The regulatory Environmental Effects Monitoring (EEM) program in Canada has found that pulp and paper mill effluents reduce the gonad size of wild fish. In such cases, there is a need for Investigation of Cause (IOC) and Investigation of Solution (IOS) studies to find the cause(s) for these responses as well as cost-effective mitigation strategies. IOC and IOS work requires the availability of practical (in terms of time and effluent volume needs) and biologically meaningful tests for assessing fish reproduction in the laboratory. One available fish reproduction test uses adult fathead minnow (Pimephales promelas) and involves a two- to three-week pre-exposure period and a three-week exposure to a test substance. Work was undertaken to determine if both the pre-exposure and effluent-exposure phases could be reduced, leading to a shorter test with a lower effluent volume requirement. For this purpose, effluent samples were taken from two thermomechanical (newsprint) pulp mills and used in tests with ..7 days of pre-exposure and 5 to 6 days of effluent exposure. Egg production was monitored in each test, and in tests with effluents from one mill, other endpoints such as gonad somatic indices and whole-body sex steroid levels, as well as vitellogenin activity in males - were measured. The shortened fish reproduction test in this study provided results similar to tests of longer duration, specifically in terms of egg production, and was able to distinguish between pulp and paper mill effluents of different potencies. The test was also found to be directly applicable for toxicity identification evaluation work as it was clearly able to distinguish between the solids and soluble fractions of a biotreated newsprint mill effluent. As such, the test is a promising tool for EEM-related IOC and IOS work. [ABSTRACT FROM AUTHOR]

The Canadian environmental effects monitoring (EEM) program is a regulated, cyclical, industry-funded program designed to determine whether receiving water impacts exist when a mill is in compliance with its discharge limits. The results from three cycles of the fish monitoring program (1992 to 2004) are available from over 200 surveys of fish compared between sites located upstream and downstream of pulp and paper mill effluent outfalls. Previous meta-analyses have shown a national average response pattern across cycles characterized by an increase in endpoints measuring energy storage and growth and a decrease in a reproductive endpoint, consistent with a response of nutrient enrichment in combination with some form of metabolic disruption. Although the national average pattern of effects was temporally consistent, there was some variability in the magnitude of effects among cycles. Questions were raised as to whether the intercycle variability was due to changes in effluent quality or due, at least in part, to other factors. The present study compares responses over the first three cycles, and shows that the choice of sentinel species is likely to be a major contributing factor to the variability in observed effects. Subset analyses using studies from mills that used the same sentinel species across cycles reveal fairly uniform responses and little evidence of significant improvements in overall fish health from cycles one to three. However, a meta-analysis using 1991 data collected from 10 mills before the implementation of the EEM program and data from the same mills collected during cycles one to three of the program reveal significantly reduced effects on relative liver weight and potential improvements in other endpoints.

Many firms worldwide have adopted environmental management systems, and some have taken the extra step and had their systems certified for the international standard ISO 14001. While institutional pressures and market demand often motivate firms to adopt an EMS, the reasons why they certify for ISO 14001 are less clear. In this study, we interviewed members of the Canadian pulp and paper industry who had either an EMS or ISO 14001 certification to understand why they may have become ISO 14001 certified. We found that task visibility and environmental impact opacity lead to differences in a firm's approach to ISO 14001 certification in the absence of coercive pressures. [ABSTRACT FROM AUTHOR]

Summary This study presents the carbon footprint of a paperback book for which the cover and inside papers were produced in the United States and printed in Canada. The choice of paper mills for both cover and page papers was based on criteria such as percentage of recycled content in the pulp mix, transport distances (pulp mill to paper mill, paper mill to print), and technologies. The cradle-to-gate assessment of greenhouse gas (GHG) emissions follows recognized guidelines for carbon footprint assessment. The results show that the production of 400,000 books, mainly distributed in North America, would generate 1,084 tonnes carbon dioxide equivalent (CO2-eq), or 2.71 kilograms (kg) CO2-eq per book. The impact of using deinked market pulp (DMP) is shown here to be detrimental, accounting for 54% of total GHG emissions and being 32% higher than reference virgin Kraft pulp. This supports findings that DMP mill GHG emissions strongly correlate with the carbon intensity of the power grid supplying the pulp mill and that virgin Kraft mills that reuse wood residue and black liquor to produce heat and electricity can achieve lower GHG emissions per tonne of pulp produced. Although contrary to common thinking, this is consistent with the Paper Task Force 2002 conclusion for office paper (the closest paper grade to writing paper or fine paper) (EDF 2002a). To get a cradle-to-grave perspective, three different end-of-life (EOL) scenarios were analyzed, all of which included a harvested wood product (HWP) carbon storage benefit for 25 years. The GHG offset concept within the context of the book editor's 'carbon-neutral' paper claims is also discussed. [ABSTRACT FROM AUTHOR]

The Canadian Environmental Assessment Act (CEAA) defines the federal environmental assessment (EA) process for evaluating the likelihood that development projects (e.g., roads, buildings, factories) will have impacts on the environment. Environmental effects monitoring (EEM) programs for mining and pulp and paper mills under the Federal Fisheries Act, define the process that is to be used to evaluate existing effects caused by liquid effluents discharged by operating facilities. The EA process occurs before a project is approved, and involves predicting whether the project is going to cause significant environmental impacts. The EEM process occurs after a project is operational, and involves determining whether an existing project has had or is continuing to have significant impacts on the environment. Ideally, the processes are complimentary, with the EA process identifying environmental attributes considered important, and the EEM process demonstrating whether predicted or unpredicted impacts occurred. The two processes are usually done in isolation so potential synergies are lost. The point of this manuscript is to justify bridging the two processes. We use the aquatic environment as the example, and briefly describe the EEM process, aquatic environment indicators, experimental designs, and typical environmental thresholds, to illustrate how the EEM and EA processes link.

Our paper, "The Insignificance of Thresholds in Environmental Impact Assessment: An Illustrative Case Study in Canada" received a critique that challenged us on a number of grounds. Namely, that we defame EIA practitioners, that we advocate EIAs to become a scientific enterprise, that we do not recognize the complexity inherent in EIA, and that EIA undergo an independent assessment by regulators. We respond to all of these points, and argue that conflict of interest is an institutional issue (not one of corrupt practitioners), and that we critique the science that forms the basis of evidence in EIA. Further, we show that the complexity and uncertainty in the critique cannot explain the findings from our paper that all cases of impact threshold exceedance were determined to be not significant in EIA. Finally, we compare the significance determinations in proponent reports to final regulator decisions and determine that they are overwhelmingly identical (93–95%). Regulators are financially independent of proponents, but their decisions on significant are heavily dependent on the information and analysis provided by the proponent reports. As regulators rely on these reports, environmental impact assessments must be based on rigorous and transparent analysis. [ABSTRACT FROM AUTHOR]

E‐commerce is increasingly popular in the fashion industry in Canada. Based on a case study, this research analysed the environmental sustainability of the returnable e‐commerce package format distributed in Canadian apparel retail channels. The case study compared the environmental impacts of a returnable polypropylene mailer to those of two different expendable packaging formats currently used by a brand owner, such as a corrugated paperboard package and a low‐density polypropylene mailer. A life cycle assessment (LCA) was conducted to examine the environmental impacts of the three packaging scenarios. The foreground data of the LCA were obtained from a brand owner and packaging suppliers in 2021. TRACI 2.1, including 10 life cycle impact categories, was used for the LCA. The comparative LCA results showed that the returnable mailer generated the lowest environmental impact for eight out of 10 impact categories when the final consumers' locations were relatively close to the brand owner or returnable packaging service provider. The expendable corrugated paperboard packaging format contributed the greatest environmental burden in all the impact categories primarily because it used a large amount of material and was relatively heavy. However, the comparative results were changed for some impact indicators depending on the final consumer's location and the number of reuse cycles for the returnable mailer. Specifically, the returnable mailer had a higher environmental impact than the expendable mailer for half of the 10 impact categories when the number of reuses for the returnable mailer was decreased to 10 cycles.

Aquatic monitoring programs are imperative for the functioning of the environmental impact assessment (EIA) process and a cornerstone for industrial compliance in Canada. However, in 2012, several leading pieces of federal environmental legislation (e.g., Canadian Environmental Assessment Act c.19, s. 52, 2012) were drastically altered, effectively weakening levels of environmental protection for aquatic ecosystems during project developments. This paper assesses the impact of CEAA 2012 on aquatic monitoring programs (and subsequent monitoring data reporting) across Canada for ten projects (five completed pre- CEAA 2012 and five completed post- CEAA 2012). Projects included four energy and six mining projects and were selected based on the following criteria: (i) representative of Canada's resource economy; (ii) project information was publicly available; and (iii) strong public interest. Projects pre - and post- CEAA 2012 exhibited few apparent differences before and after environmental regulatory changes. However, wide discrepancies exist in numbers and types of parameters reported, along with a lack of consistency in reporting. Projects pre- CEAA 2012 provided more follow-up monitoring commitments. Although qualitative differences remain inconclusive, this paper highlights requirements for further assessment of aquatic monitoring and follow-up programs in Canada. Recommendations for the government to consider during reviews of the federal environmental assessment processes include (i) improved transparency on the Canadian Environmental Assessment Agency website (); (ii) creation of a legally binding standardized aquatic monitoring program framework to ensure that all Canadian aquatic ecosystems are monitored with equal rigour; and (iii) commitments and justification related to frequency of aquatic monitoring of water quality.

This Special Section explores the interplay between Indigenous peoples, industry, and the state in five proposed and active mining projects in Canada and Sweden. The overall aim is to identify factors shaping the quality of Indigenous community-industry-state interactions in mining and mine development. An ambition underlying the research is to develop knowledge to help manage mining related land-use conflicts in Sweden by drawing on Canadian comparisons and experience. This paper synthesizes the comparative research that has been conducted across jurisdictions in three Canadian provinces and Sweden. It focuses on the interplay between the properties of the governance system, the quality of interaction and governance outcomes. We combine institutional and interactive governance theory and use the concept of governability to assess how and why specific outcomes, such as mutually beneficial interaction, collaboration, or opposition, occurred. The analysis suggests there are measures that can be taken by the Swedish Government to improve the governability of mining related issues, by developing alternative, and more effective, avenues to recognize, and protect, Sámi rights and culture, to broaden the scope and increase the legitimacy and transparency of the EIAs, to raise the quality of interaction and consultation, and to develop tools to actively stimulate and support collaboration and partnerships on equal terms. Generally, we argue that Indigenous community responses to mining must be understood within a larger framework of Indigenous self-determination, in particular the communities' own assessments of their opportunities to achieve their long-term objectives using alternative governing modes and types of interactions.

Green supply chain management (GSCM) involves consideration of environmental impacts of all the processes involved in a typical supply chain to minimise their negative consequences. In this paper, we present a DEMATEL-based approach for investigating barriers in GSCM in Canadian context. Seven manufacturing firms from electronic goods sector are involved. The results of our study yield three main categories of barriers. These barriers are knowledge-related (lack of awareness of the environmental impacts on business, lack of training courses/consultancy/institutions to train, monitor/mentor progress specific to each industry, lack of technical expertise and difficulty in identifying environmental opportunities), commitment-related (lack of corporate social responsibility) and product design-related (complexity of design to reuse/recycle used products). The proposed study is one of the first few to be conducted in the Canadian context for green supply chain barrier analysis for electronic goods sector. Secondly, the barriers are investigated through causality and prominence relations which can help decision-makers, policy planners and managers of organisations in addressing those critical few for making green supply chain practices a success.

Indigenous-led impact assessment (ILIA) is a project review process designed and conducted with meaningful input and an adequate degree of control by Indigenous peoples. Using a case-based approach, this paper examines ILIAs conducted in Canada. The research – tools for ILIA – provides examples of options for the design and implementation of ILIA processes which have been utilized by Indigenous Nations while making their own determinations regarding if and how development should occur according to their unique locations, histories, natural resource issues, and governance. We have identified five tools: framework agreements; customized review panels; land use and consultation policy; impact and benefit agreements; and land use planning. Each tool is described along with a case study example of how the tool was applied within ILIA. Although our work focuses on Canada, the examples and tools can be valuable for Indigenous peoples and EIA practitioners in jurisdictions elsewhere who are looking to understand how ILIA might be operationalized to reflect their settings, values, and priorities. The results are helpful to Indigenous governments and groups looking to develop their own approaches to assessment, and for understanding the relative strengths and experiences of options they may consider or adapt for their own needs.

This paper examines two fundamental and inter-related tensions relating to environmental assessment between the desire to be proactive, promoting sustainable development and the more traditional practice of preventing harm, as well as the need to balance a predictable, expeditious and efficient process with transparency and inclusive deliberation. Proposed reforms to the environmental assessment process in Ontario, Canada, are examined as a case in point, showing how the recommendations in Ontario are consistent with international trends. In particular, over-arching principles need to be embedded in more precise sector-specific policies to enable environmental assessment processes to meet these competing goals. [ABSTRACT FROM AUTHOR]

As part of a large hydroelectric project in northern Québec (Canada), a portion of the flow of the Rupert River was diverted toward the existing La Grande hydroelectric complex. As a result of the partial diversion, the discharge of the Rupert River at its mouth is reduced by an average of 50% annually. This corresponds to an 18% decrease in the total freshwater inflow into the bay and, thus, to a shift of the upstream limit of the saltwater intrusion in Rupert Bay. Changes in saltwater intrusion had been predicted numerically as part of the project's environmental impact assessment (EIA). In the project's conditions of authorization, monitoring the hydraulic conditions and the extent of saltwater intrusion in the Rupert Bay was required by government authorities. The objective of this paper is to present the results of this environmental monitoring and, more specifically, to validate the modifications predicted in the EIA in terms of both saltwater intrusion limit and hydraulic conditions in the Rupert Bay. Results obtained during 2 years of monitoring are within the predicted trends and order of magnitude of changes anticipated in the EIA. The results, thus, confirm that the shift of the upstream limit of the saltwater front along the channels of the bay was conservatively predicted by numerical modeling. [ABSTRACT FROM AUTHOR]

Adaptive management theory recognises that we cannot make foolproof predictions of environmental impacts of human interventions into complex ecosystems. It mandates that environmental managers retain the ability to respond to change and inaccurate predictions. The Canadian Environmental Assessment Act (CEAA) authorises government to implement adaptive management into project follow-up. A key Canadian court decision has interpreted this to mean that adaptive management enables projects to proceed when mitigation measures are uncertain, that could be used in tempering the significance of impacts, and that it offsets the impact of the precautionary principle. Taking a legal perspective, the paper discusses how adaptive management may benefit environmental assessment, how the CEAA uses it, how a court has misinterpreted its role in the CEAA, and how it relates to the precautionary principle. In closing the paper sets out general lessons from the Canadian experience for the use of adaptive management in environmental assessment generally. [ABSTRACT FROM AUTHOR]

The Atlantic Coastal Action Program (ACAP) is a unique, community-based program initiated by Environment Canada in 1991 to help Atlantic Canadians restore and sustain watersheds and adjacent coastal areas. ACAP is the eastem-most Environment Canada Ecosystem Initiative. The ACAP family is currently made up of 14 ecosystem-based organizations in the four Atlantic provinces. Each one of these non-profit organizations operates independently, but is formally linked under the umbrella of ACAP to represent a force stronger than the individual parts. In Environment Canada's experience, the program consistently demonstrates the value of a community-based approach and produces results on an ecosystem basis. This paper will examine some of the impacts of ACAP in terms of economics, credible community science, and environmental results which most often align with Environment Canada's objectives. It will explore the influences of the community-based approach to environmental management on multiple scales (local, regional, etc.). Through examples, the paper will demonstrate the effectiveness of ACAP in influencing some of the policies, programs and attitudes of various levels of government and industry in the region, as well as describe how the community-based model has been exported internationally. The paper will conclude with a discussion on a planned path forward for ACAP. [ABSTRACT FROM AUTHOR]

This paper argues that small island states and territories provide a case for the application of health impact assessments. Their characteristic ecological fragility, vulnerability, relatively small size and limited resources give cause for environmental impact concerns. The tendency, therefore, is for decision-makers and developers to focus upon the economic benefits of proposed development projects while mitigating their environmental impacts, paying little attention to health impacts. The paper defines health status and health determinants and provides a toolkit of guidelines for carrying out health impact assessment in small islands. It discusses the approaches and lessons from the UK and Canada by which assessors in small islands can develop health impact assessment processes within their own contexts. The paper identifies the positive and negative health impacts that assessors should consider in assessing the impacts from tourism. The conclusions point to policy implications and the need for decision-makers to incorporate health impact assessment into their respective island's planning and regulatory frameworks.

Ecological connectivity within and across the boundaries of protected areas has become a key theme for conservation practitioners in Canada and internationally in recent years. This paper describes four case studies involving the assessment of ecological connectivity in national parks in Canada. Assessments occurred in three tiers: strategic environmental assessments conducted during management planning processes, an intermediate tier focussed on research and partnering at more refined spatial scales, and project level environmental impact assessments. While improved data, modelling and research on thresholds is needed, the multi-tiered approach facilitated the analysis of information and the collaboration with partners at scales required to conserve ecological connectivity within and across the boundaries of national parks. This work demonstrates practical approaches to conserving ecological connectivity as a response to biodiversity loss and highlights impact assessment in multiple tiers as a solution that is transferable to other sectors.

This paper examines the consideration of climate change in environmental assessment (EA) in the liquefied natural gas (LNG) sector, British Columbia, Canada. Based on an analysis of recent EA applications, results show that climate change is considered, to some extent, in all phases of EA for most LNG projects. However, stakeholders indicate a dissatisfaction with practice – often based on expectations about EA that exceed what it can deliver as a project-based tool, and sometimes based on an incomplete understanding of existing climate change legislation and targets. Results also indicate inconsistent application of existing climate change requirements across project EAs. Notwithstanding proponents often addressing climate change in their EA applications, climate change tends to receive little attention in project decision and approval conditions. The paper concludes with recommendations for better practice climate change consideration in EA that is commensurate with the scope and scale of project-level issues, complemented by more strategic EA and economic instruments.

The article offers information on how Environmental Impact Assessment (EIAs) work, both by technical practice and regulatory process, and of the nature and motivations of those who conduct and review EIAs. It mentions that the many apparent faults and limitations of EIA practice may appear to cast a shadow on the legitimacy of their findings; and also mentions that hypothesis outcome can be reflective of the success of the combination of a good project design and environmental management.

Our work analyzed Indigenous partnership arrangements and conditions associated with natural resource development, specifically, the capacities identified by Indigenous peoples needed to participate in resource wealth generation. The review was needed to take stock of previously understudied and new partnerships emerging in Canada's rapidly growing natural resource sectors where cross-cultural collaboration is becoming a feature, and in some cases a requirement, of new ventures. Results illustrate nine categories of arrangements (i.e., land use/regional planning processes; IBAs; MOUs; Indigenous businesses, joint ventures; environmental assessments; revenue sharing; advisory committees; and regional economic councils) used by Indigenous communities and their partners to assert their control and derive benefits from natural resource extraction. These included highly formal and technical legal arrangements, such as Impact and Benefit Agreements, and less formal arrangements such as Memorandums of Understandings and advisory committees. Using the five capitals' (social, human, financial, built, and natural) approach we also synthesized existing knowledge of partnership capacities and benefits. We found benefits in each of the five capital areas, most of which were forms of human capital. Employment (50%), improved decision making (46%), and also financial support (33%) were the top cited benefits. Results build to the conclusion that differences exist between capacities needed to start working together (pre-existing supporting conditions), and those built through collaboration (new or enhanced capitals as beneficial outcomes). Development models will produce more and sustainable benefits where capacity building is both an explicit process objective and outcome of new partnership designs. [ABSTRACT FROM AUTHOR]

This paper reflects on the state of cumulative effects research in Canada and future directions and challenges. The assessment and management of cumulative effects has been an enduring theme in the impact assessment literature, and scholars have consistently identified the challenges to assessing and managing cumulative effects under regulatory, project-based impact assessment. Current research on cumulative effects is focused largely on the development of frameworks and methodologies to advance cumulative effects assessment and management from individual projects to broader regional scales, and on developing the science and tools for assessing and monitoring cumulative effects. Ensuring that scholarly research continues to shape cumulative effects practice in the future requires that scholars not only attempt to improve practice under current existing regulatory processes, but also push the boundaries to ensure that decision processes also evolve so as to be accommodating of new and innovative approaches to cumulative effects at regional scales. This requires interdisciplinary approaches and sustained research funding, both of which present practical challenges to scholars, and research programmes that are developed in collaboration with industry, governments and communities.

An introduction is presented in which the editor discusses various reports within the issue on topics including the introduction of Strategic Environmental Assessment (SEA) for the offshore oil and gas industry of Canada, provincial SEA systems' slow establishment in China, and how the financial industry may incorporate climate change-related risk and resource efficiency considerations into its operating processes better.

Cumulative effects assessment (CEA), as a required practice for the environmental assessment (EA) of projects in many countries, faces several practical challenges, especially related to biodiversity. Drawing on the perspectives and experiences of Canadian EA practitioners, this paper explores options or drivers of change for improving project-based assessment to better tackle cumulative effects on biodiversity. An on-line survey was conducted with 40 professionals from the private sector, government departments/agencies, universities, and non-governmental organizations, examining the current challenges and opportunities regarding: CEA process for biodiversity; responsibilities for undertaking CEA tasks; resources to support and promote good CEA practice. In terms of process, there is shared understanding on: (i) the need of EA terms of reference to provide specific directions on CEA; (ii) CEA should capture both human and natural drivers of cumulative change; (iii) spatial boundaries for CEA should be based on ecological boundaries. There are dissenting views about: (i) whether CEA should consider all valued components (VCs) potentially affected by a project or only those for which residual effects are predicted; and (ii) delimitation of future temporal limits. In terms of responsibilities, participants agreed that project proponents should retain a central role in conducting CEA, but government agencies should lead the collection/provision of information about other projects in the study area and baseline VC conditions. Information and knowledge management resources could be also applied in the context of governmental agencies and consultancy firms to support CEA for biodiversity. [ABSTRACT FROM AUTHOR]

The objective of this paper is to assess the impact of proposed Canadian climate change mitigation policies (discounting and carbon pricing) on cost, energy use, and greenhouse gas (GHG) emissions in the single-objective design/expansion optimization of the Amherstview water distribution system in Amherstview, Ontario, Canada. The single-objective optimization problem is solved with the elitist genetic algorithm (EGA). The optimization approach is used in a parametric analysis to examine the impact of discounting and carbon pricing on GHG reductions for cement-mortar ductile iron and polyvinyl chloride pipe materials. Preliminary results indicate that the discount rate and carbon prices investigated had no significant influence on energy use and GHG mass in the Amherstview system and did not meet the emission-reduction targets set by the Canadian government. This result was attributed to a number of factors, including adequately installed hydraulic capacity in the Amherstview system, the use of a time-declining GHG emission intensity factor, and the scope of the expansion problem.

The aim of this paper is to explore regional variation in the implementation of Environmental Impact Assessment follow-up in India and to identify causes of such variations. In doing so, forty-three semi-structured interviews were carried out across the Indian mining and environment sector. The findings from the interviews confirm that regional variation in follow-up implementation is a result of social, environmental, economical and political factors. To further explore these factors, three case studies of open cast coal mining were conducted. The findings of the case studies offer insight as to how the factors identified during the interviews influence follow-up outcomes. Furthermore, it reflects how the nature of such variation is not always true to what is perceived about them. Subsequently, the findings from the interviews and case studies help in contributing to the existing best practice of EIA follow-up and developing recommendations for achieving better follow-up outcomes in India.

This paper reviews briefly the history of Canada's civilian nuclear energy program and the consideration of the problem of long-term disposal of nuclear waste. It shows that, after a period of twenty years of initial official deliberations on this problem, the decision making process foundered in the face of a specific dilemma: how to include, within an integrated assessment framework, both "technical" (expert judgment) and "social" (public acceptability) considerations. It argues that an expanded risk management framework, illustrated below, now provides such a framework: ["Multiple line equation(s) cannot be represented in ASCII text"]. The remainder of the paper reviews and comments on a decision making exercise, carried out in Canada in the year 2004, and using a method known as multiattribute utility analysis (MAU), that provided a new approach to the issue of the management of nuclear waste. It argues that the MAU method has some distinctive advantages, over earlier approaches, where intrinsically controversial risk management situations are concerned. [ABSTRACT FROM AUTHOR]

Since 2016, Canada's federal government has pledged to factor in upstream emissions during the environmental impact assessment of fossil fuel energy projects. The upstream emissions attributable to a proposed project could be compared against a rejection threshold—a maximum permissible level of emissions—or the firm could be mandated to offset the attributed emissions. We adopt a cooperative game-theoretic model and propose the nucleolus mechanism to apportion upstream emission responsibilities in a fossil fuel supply chain, represented by a directed tree, wherein the nodes correspond to various entities in the supply chain such as extractors, distributors, refineries, and end consumers. The nucleolus allocation avoids the distortionary effects of double counting and exhibits a certain consistency property that is especially important in a regulatory context wherein fossil fuel supply chains span multiple legal jurisdictions. We develop a polynomial-time algorithm to compute the nucleolus and further prove that it arises as the unique subgame perfect equilibrium allocation of a noncooperative game induced by two easily stated and verifiable policies, thereby providing an implementation framework. We then demonstrate the strong Nash stability of the nucleolus mechanism subject to the two policies, study its sensitivity to parameter changes, and characterize it on the basis of fairness considerations. Furthermore, under the common assumption that the emissions allocated to a firm and the resulting financial penalties do not impact the revenues from the firm's core operations, we also provide lower-bound guarantees on the welfare gains it delivers to firms in the fossil fuel supply chain and on the incentives it offers such firms to adopt emission abatement technologies. Finally, we contextualize our discussion with a case study on a proposed expansion of the Trans Mountain pipeline in Western Canada. This paper was accepted by Chung Piaw Teo, optimization.

Plans to raise the Ross Dam on the Skagit River by the American utility, City Light, will flood a valley in Canada and have generated a conflict of resource use between conservationists and proponents of economic progress. This paper examines the variety of uses of the valley at present, and their expansion for recreational use by modest improvements. Such expanded use is compared with uses available if the valley is flooded. The comparison is expressed in economic terms. The paper then continues with a critique of economic analysis to such problems of resource allocation and develops an approach to ecological resource allocation. A schedule and analysis of alternative uses is offered. The economic and ecological conclusions are examined, and it is found that the latter method is more appropriate to practical problems of allocation, at least with regard to natural resources than the former..

This paper presents and demonstrates a spatial framework for the application of strategic environmental assessment (SEA) in the context of change analysis for urban wetland environments. The proposed framework is focused on two key stages of the SEA process: scoping and environmental baseline assessment. These stages are arguably the most information-intense phases of SEA and have a significant effect on the quality of the SEA results. The study aims to meet the needs for proactive frameworks to assess and protect wetland habitat and services more efficiently, toward the goal of advancing more intelligent urban planning and development design. The proposed framework, adopting geographic information system and remote sensing tools and applications, supports the temporal evaluation of wetland change and sustainability assessment based on landscape indicator analysis. The framework was applied to a rapidly developing urban environment in the City of Saskatoon, Saskatchewan, Canada, analyzing wetland change and land-use pressures from 1985 to 2011. The SEA spatial scale was rescaled from administrative urban planning units to an ecologically meaningful area. Landscape change assessed was based on a suite of indicators that were subsequently rolled up into a single, multi-dimensional, and easy to understand and communicate index to examine the implications of land-use change for wetland sustainability. The results show that despite the recent extremely wet period in the Canadian prairie region, land-use change contributed to increasing threats to wetland sustainability. [ABSTRACT FROM AUTHOR]

Cost-benefit analysis and economic impact analysis both provide the ability to assess projects' economic impacts, but through different methodological approaches and perspectives. In Canada and elsewhere, cost-benefit analysis is often eschewed in favour of economic impact analysis in environmental assessment processes. This paper presents a criteria-based evaluation of the two methods and shows that cost-benefit analysis has numerous strengths relative to economic impact analysis but that both methods are useful. Consequently, we recommend that the environmental assessment process be reformed to include cost-benefit analysis complemented by economic impact analysis to provide decision-makers with more complete information.

Quantifying a proposed project's greenhouse gas (GHG) emissions and scrutinizing their effect on climate change are increasingly required in Canadian environmental assessment (EA) processes. This paper investigates to what degree an EA authority's intention for the inclusion of GHG considerations has resulted in implementation into environmental impact statements (EISs) by proponents and how these considerations influence the achievement of GHG reduction targets. Fifteen projects across five Canadian jurisdictions were reviewed. The examination revealed that well-developed intentions by EA authorities did not necessarily result in proponents following guidelines for GHG consideration in their EISs due to the absence of regulation or clearly defined policies. Conversely, even though intentions by an EA authority are underdeveloped in some jurisdictions, EISs sometimes exhibited thorough GHG assessments due to mechanisms in the EA process through which GHG consideration by the proponent could be compelled. The examination did not reveal how GHG consideration in EA currently assists in meeting reduction targets. A GHG emissions limit imposed during the EA process could link EA to success in meeting these targets. [ABSTRACT FROM AUTHOR]

Given the scale of plastic generation, its persistent presence in the environment, and the urgent need to transition to a net-zero emissions paradigm, managing plastic waste has gained increasing attention globally. Developing an effective strategy for plastic waste management requires a comprehensive assessment of the potential benefits offered by different solutions, particularly with respect to their environmental impact. This study employs the life cycle assessment (LCA) methodology to evaluate the environmental impact of two alternative scenarios to the As-Is scenario for managing plastic waste in the province of British Columbia in Canada. The LCA results suggest that the Zero Plastic Waste scenario, which heavily relies on chemical recycling, may not inherently result in a reduced environmental footprint across all impact categories. This is notable when the focus is solely on end-of-life treatment processes, without considering the produced products and energy. The Intermediate scenario reduces the amount of plastic waste sent to landfills by directing more end-of-life plastic to mechanical recycling facilities. This scenario provides immediate benefits for resource conservation, with a minimal increase in the environmental burden resulting from treatment processes. Nonetheless, achieving a net-zero transition requires combining traditional and emerging recycling technologies. The current study could offer some guidance to policymakers on strategies for fostering more sustainable management of plastic waste. [ABSTRACT FROM AUTHOR]

The boreal zone and its ecosystems provide numerous provisioning, regulating, cultural, and supporting services. Because of its resources and its hydroelectric potential, Canada's boreal zone is important to the country's resource-based economy. The region presently occupied by Canada's boreal zone has experienced dramatic changes during the past 3 million years as the climate cooled and repeated glaciations affected both the biota and the landscape. For about the past 7000 years, climate, fire, insects, diseases, and their interactions have been the most important natural drivers of boreal ecosystem dynamics, including rejuvenation, biogeochemical cycling, maintenance of productivity, and landscape variability. Layered upon natural drivers are changes increasingly caused by people and development and those related to human-caused climate change. Effects of these agents vary spatially and temporally, and, as global population increases, the demands and impacts on ecosystems will likely increase. Understanding how humans directly affect terrestrial and aquatic ecosystems in Canada's boreal zone and how these effects and actions interact with natural disturbance agents is a prerequisite for informed and adaptive decisions about management of natural resources, while maintaining the economy and environment upon which humans depend. This paper reports on the genesis and present condition of the boreal zone and its ecosystems and sets the context for a detailed scientific investigation in subsequent papers published in this journal on several key aspects: carbon in boreal forests; climate change consequences, adaptation, and mitigation; nutrient and elemental cycling; protected areas; status, impacts, and risks of non-native species; factors affecting sustainable timber harvest levels; terrestrial and aquatic biodiversity; and water and wetland resources.

The absence of Regional Strategic Environmental Assessment (R-SEA) in Canada's western Arctic has raised many questions concerning the country's preparedness for offshore Arctic energy development, given the constraints of project assessments in addressing long-term cumulative impacts of energy development on the marine environment and local communities. There has been much interest in R-SEA in recent years, and a growing body of research on the benefits of strategic approaches to environmental assessment, but relatively little attention has been given to implementation. This paper examines key opportunities for and challenges to the implementation of R-SEA in Canada's western Arctic. Results reinforce concerns that the current approach to environmental assessment in Canada's western Arctic is insufficient to address expanding offshore energy development. However, results also indicate several challenges to be addressed to advance R-SEA in the offshore environment including governance, stakeholder resistance to a futures-based approach, the timing of implementation, managing the diversity of expectations about R-SEA, and the nature and scope of alternatives assessment.

Stakeholder participation is a vital component of successful Strategic Environmental Assessment (SEA). SEA, an evaluation of environmental and sustainability consequences of strategic initiatives prior to their implementation, seeks to ensure that various stakeholder perspectives are considered early in the strategic decision-making process. However, once the implementation decisions are taken, are the stakeholders consulted with, or involved in, strategy implementation and SEA follow-up? If so, how can participatory processes benefit delivery of strategies and follow-up? These questions remain largely unexplored due to the conventional focus on ex ante SEA and limited knowledge about SEA follow-up. This paper explores the role and potential of stakeholder participation processes in facilitating SEA follow-up in the case of a 20-year Pasquia-Porcupine Forest Management Plan (FMP), in Saskatchewan (Canada). It explores different forms of stakeholder participation in the FMP and SEA follow-up implementation and identifies the associated benefits for SEA follow-up. [ABSTRACT FROM PUBLISHER]

Cumulative environmental effects from the offshore oil and gas industry in Canada are inadequately addressed in the Environmental Assessment process due to the complexity of analysis required to overcome unknowns with respect to offshore environments. Limited Environmental Assessments can lead to deleterious consequences for wildlife populations and their habitats dependent on offshore marine ecosystems, particularly as adverse effects become additive and synergistic. A Strategic Environmental Assessment generates guiding policies and programmes for future industrial activities, while taking environmental concerns from all and potential sources into consideration. To address the cumulative impacts of the offshore oil and gas industry in Canada's three marine regions, this paper advances the idea of a National Strategic Environmental Assessment to ensure the health of marine ecosystems is secured throughout present and future industrial activities sustainably.

On the 23 March 2018, the most recent developments of the environmental impact assessment (EIA) law were examined by experts in Helsinki. The main theme of the conference was the comparison of the implementation experiences of various countries concerning the reformed EU EIA Directive. The European EIA debate was reflected against experiences in Canada. This paper examines the key points of the conference presentations and the lessons of the event. [ABSTRACT FROM AUTHOR]

Watersheds are under increasing pressures from the cumulative environmental effects of human actions. Reviews of recent practice suggest that cumulative effects assessment and management (CEAM) has failed to capture the full range of stressors to Canada's watersheds. Indeed, the limitations to CEAM have been well documented; yet, there has been limited constructive evaluation to help explain why CEAM has failed to advance. In this paper we examine the underlying challenges to the assessment and management of cumulative effects in a watershed context. Based on lessons emerging from the South Saskatchewan watershed, Canada, challenges to CEAM in watersheds include stakeholder understanding and interpretation of cumulative effects; limitations in the scale of current EA practices in watersheds; data challenges; the lack of established thresholds for watershed effects; and lack of clarity regarding watershed science and regulatory capacity. The merits of a watershed-based approach to CEAM to help address these challenges to practice are explored. [ABSTRACT FROM AUTHOR]

Reconciling diverse forest values within policy and decision-making processes is an ongoing challenge in forestry. The use of environmental impact assessment (EIA) provides potential for improving forest management and making it more responsive to diverse interests. This paper examines EIA in Canadian and Finnish forest planning. In Finland there has been a reluctance to see EIA as a tool for forest planning while in Canada some provinces have long applied EIA to forest management. Ontario, Canada, provides one example of applying EIA to forest planning at a range of scales in order to advance integrated planning and help conflict management. The paper provides a brief analysis of the Finnish forest planning system, an illustration of the Ontario EIA forest management experience, and then considers the application of EIA to Finnish forest management. The paper concludes that EIA may be workable for Finnish state forests and would likely enhance planning and management, but given the existing institutional frameworks EIA would be difficult to apply to private forests.

Abstract: Photovoltaic installations (PV-systems) are heavily promoted in Europe. In this paper, the Life Cycle Analysis (LCA) method is used to find out whether the high subsidy cost can be justified by the environmental benefits. Most existing LCAs of PV only use one-dimensional indicators and are only valid for regions with a high solar irradiation. This paper, however, presents a broad environmental evaluation of residential PV-systems for regions with a rather low solar irradiation of 900–1000kWh/m2/year, a value typical for Northern Europe and Canada. Based on the Ecoinvent LCA database, six Life Cycle Impact Assessment (LCIA) methods were considered for six different PV-technologies; the comprehensive Eco-Indicator 99 (EI 99) with its three perspectives (Hierarchist, Egalitarian and Individualistic) next to three one-dimensional indicators, namely Cumulative Energy Demand (CED), Global Warming Potential (GWP) and the Energy Payback Time (EPT). For regions with low solar irradiation, we found that the EPT is less than 5 years. The Global Warming Potential of PV-electricity is about 10 times lower than that of electricity from a coal fired plant, but 4 times higher when compared to a nuclear power plant or a wind farm. Surprisingly, our results from the more comprehensive EI 99 assessment method do not correlate at all with our findings based on EPT and GWP. The results from the Individualist perspective are strongly influenced by the weighting of the different environmental aspects, which can be misleading. Therefore, to obtain a well-balanced environmental assessment of energy technologies, we recommend a carefully evaluated combination of various impact assessment methods. [Copyright &y& Elsevier]

Environmental assessment (EA) has long been recognized as one of Canada's most important regulatory tools for protecting the environment while meeting the public's expectations for economic growth. The value of this process resides in its ability to provide useful information to decision-makers in an efficient and effective manner. In Canada, the federal government is responsible for implementing the Canadian Environmental Assessment Act 1995, while provincial governments are responsible for administering their own EA legislation. Importantly, such a multi-tiered approach to regulation can have a major impact on the collective outcomes of the decisions being made. This paper presents the results of a constant comparison of provincial, territorial, and federal Environmental Assessment Acts to clarify the extent to which requirements vary between jurisdictions in Canada. It then discusses these results in the context of the challenges facing multi-jurisdictional regulation of EA in Canada. Our study also demonstrates that constant comparison is an effective method for determining the common ground between the requirements of different environmental legislation, providing a grounded starting point from which strategic discussions on co-ordination between governments might proceed.
