This paper presents the results of a stated preference choice experiment designed to estimate the non-market benefits derived by UK residents from the conservation of ecosystem goods and services resulting from implementation of proposed Marine Conservation Zones under the UK Marine and Coastal Access Bill (2008). The results inform an impact assessment that compares benefits to projected policy costs. As demonstrated in a paper by Hussain et al (2010) ex ante benefit estimation is complicated by the scientific uncertainty and data gaps that hinder the development of a bottom–up valuation of the ecosystem goods and services provisioned by the policy. A choice experiment approach provides an alternative top–down valuation by approximating policy outcomes, which are spatially remote from beneficiaries and therefore arguably only appreciated passively or in terms of non-use or existence value for broadly defined attributes of the policy. The choice experiment shows preferences for both halting the loss of or increasing marine biodiversity, and the provision of other environmental services relative to current trajectories of decline. Survey respondents were indifferent to the levels of restrictions on activities needed to achieve these outcomes. As a top–down estimate of policy benefits, the study suggests that welfare improvements from the Marine Bill significantly outweigh projected regulatory costs. [Copyright &y& Elsevier]

The consumption patterns of Western nations are generally deemed to be unsustainable. Yet there is little attempt to restrain either material throughput or income growth. Nonetheless, in the face of the need to make ‘deep’ cuts in carbon emissions (for instance), consumption restraint may be a perfectly legitimate response. This paper explores the potential for a Reduced Consumption Scenario in the UK constructed by assuming that households achieve a specific ‘minimum income standard’ which is deemed to provide a decent life for each household type. The minimum income standards are taken from a recent study for the Joseph Rowntree Foundation and include not only subsistence commodities such as food, warmth and shelter but also the means to participate effectively in society. The Joseph Rowntree Foundation study produced detailed household expenditure budgets for these income standards. The paper uses an environmentally extended Quasi-Multi-Regional Input–Output model to estimate the greenhouse gas (GHG) emissions required in the production and distribution of all goods and services purchased according to these budgets. Our results show that average household GHG emissions in the UK would be around 37% lower in the Reduced Consumption Scenario than they are currently. We explore several implications of these findings including: the need to change social norms around consumption, the need for investment to improve the thermal performance of homes and the need to develop new transport infrastructures. We also address the potential to reduce emissions below the level achieved in this Scenario and discuss the implications for policy. [Copyright &y& Elsevier]

This paper presents an estimate of the benefits of the proposed designation of a network of marine conservation zones (MCZs) in English territorial and UK offshore waters. This ex ante analysis was undertaken as part of a cost–benefit evidence base to inform implementation of the proposed UK Marine and Coastal Access Bill. This Bill is part of an ambitious plan to designate and manage UK marine areas using an Ecosystems Approach. Benefits are measured in terms of anticipated increases in the value of ecosystem goods and services provisioned by MCZs relative to the counterfactual, i.e. no designation. The principal valuation and thus policy challenge is presented by the need to use benefits transfer in a context where biophysical provisioning functions are not well-developed, where there are gaps in the valuation literature related to temperate marine ecosystem goods and services, and where values (where available) are presented in aggregate terms. This paper develops and applies a methodology that first apportions these aggregate benefits across the diverse range of marine landscapes and habitats and then estimates the marginal benefit of protection. The value of benefits was calculated for three different configurations of MCZs under two different management regimes. We estimate a benefit range from designation of between £10.2billion and £23.5billion in present value terms, applying a 3.5% discount rate. The study questions the extent to which a defensible policy evidence base can be developed in the absence of primary valuation data and where benefit estimates are reported in aggregate terms.

The circular flow diagram, whether in its limited form in macroeconomics, or broader form in ecological economics, depicts a duality of flows – physical resources in one direction with financial transactions in the opposite. Biophysical models of the economy can be constructed based on the physical flows and their associated stocks. In previous work, I demonstrated how the accumulation of wealth – measured by the capital stock – can be established using a biophysical model. With capital, energy use, and the distribution of labour determined by biophysical economics, here I investigate the range of potential distributions of wealth – profits versus wages – that follow in the political economy. The analysis is conducted using a four-sector model of Great Britain's economy from 1760 to 1913, including agriculture, coal mining, construction & materials, and production of goods and services. Energy price is a key variable in the model, influencing the distribution of income between different sectors. Taking the price of coal at historically observed values, the distribution of total factor income per worker is plotted as a trade-off between annual wages and profits per worker for example years of 1761, 1817, and 1871. The plots reveal how possible alternative distributions of income might be achieved under different political-economic regimes, subject to the same biophysical constraints. Conclusions are framed in the context of the grand challenges faced by ecological economists of developing environmentally sustainable economies with a just and equitable sharing of resources. [Display omitted] • The paper frames the challenge of wealth distribution subject to biophysical constraints. • Prices, wages, and profits are added to a biophysical model of the Industrial Revolution. • The distribution of total factor income per worker is posed as a trade-off between wages and profits per worker. • Changes in energy price are shown to impact the distribution of income between and within sectors. • The influence of the political economy on the biophysical economy is also discussed.

Using the modelling tool ELESA (Econometric Lifestyle Environment Scenario Analysis), this paper describes forecast scenarios to 2030 for UK household expenditure and associated (direct and indirect) greenhouse gas (GHG) emissions for 16 expenditure categories. Using assumptions for real household disposable income, real prices, ‘exogenous non-economic factors’ (ExNEF), average UK temperatures and GHG intensities, three future scenarios are constructed. In each scenario, real expenditure for almost all categories of UK expenditure continues to grow up to 2030; the exceptions being ‘alcoholic beverages and tobacco’ and ‘other fuels’ (and ‘gas’ and ‘electricity’ in the ‘low’ scenario) leading to an increase in associated GHG emissions for most of the categories in the ‘reference’ and ‘high’ scenarios other than ‘food and non-alcoholic beverages’, ‘alcoholic beverages and tobacco’, ‘electricity’, ‘other fuels’ and ‘recreation and culture’. Of the future GHG emissions, about 30% is attributed to ‘direct energy’ use by households and nearly 70% attributable to ‘indirect energy’. UK policy makers therefore need to consider a range of policies if they wish to curtail emissions associated with household expenditure, including, for example, economic measures such as taxes alongside measures that reflect the important contribution of ExNEF to changes in expenditure for most categories of consumption.

In this paper, we adopt a recent OECD framework and examine the role of external policy tools and internal firm specific factors for stimulating three different types of eco-innovations that range on a spectrum of lower to higher technological and environmental impacts: End-of-Pipeline Pollution Control Technologies, Integrated Cleaner Production Technologies and Environmental R&D. Using a novel firm-level dataset from a DEFRA survey, we estimate a Tobit model, which provides empirical evidence showing that these eco-innovations are motivated by different external policy tools and internal firm specific factors. Our findings indicate that End of Pipeline Technologies and Integrated Cleaner Production Technologies are mainly driven by equipment upgrade motives with a view of improving efficiency while environmental regulations are effective in stimulating the End-of-Pipeline technologies and Environmental R&D. Interestingly, alongside government induced regulations, we find that market factors, mainly motivated by cost savings, are effective in driving Environmental R&D. Finally, ISO14001 certification is effective in strengthening the positive impact of environmental management systems on both End-of-Pipeline technologies and Environmental R&D while CSR policies have no significant impact on motivating any of the eco-innovations.
