To achieve the goal of carbon reduction, China has been piloting the Carbon Emission Trading System (CETS) since 2013. As the economy faces a downward trend, it is significant to explore the impact of CETS on business development. There is still debate in academia about whether this policy can boost the level of business development. This paper, based on all A-share data of listed companies in China from 2009 to 2018, uses the Difference in Differences (DID) model to verify the impact of CETS on the input of capital and labor factors and the level of technology in enterprises and discusses the industry heterogeneity of this impact in detail. Placebo tests, propensity score matching, and triple differences ensure the robustness of the conclusions. In further research, this paper decomposes the policy effect of CETS. It regresses the impact of carbon quota prices and carbon market trading scale on business development. The final conclusion is that CETS has a positive impact on the input of capital and labor in enterprises and a negative impact on the level of technology. After distinguishing industries, this conclusion shows differences according to different characteristics of high emissions and low emissions. In addition, the increase in carbon quota prices hinders business development, while the scale of carbon market trading shows an inverted "U" relationship with business development. The article provides meaningful policy references for China and countries in the early stages of CETS construction. [ABSTRACT FROM AUTHOR]

Based on the manually collected carbon information disclosure data for the Chinese listed companies from 2009 to 2015, this paper examines the influencing factors of carbon information disclosure from the stakeholders' perspective. The results show that among external stakeholders, pressures from government and customers can improve the level of firm carbon information disclosure, but the effects of creditor, supplier and competitor on firm carbon information disclosure level are not significant. Among internal stakeholders, the major shareholders, institutional investors, and employees can improve the level of firm carbon information disclosure, but the effects of foreign investors (QFII) on carbon information disclosure are not significant. Among third-party stakeholders, environmental protection organizations and audit institutions can improve the level of firm carbon information disclosure. We hope that findings of this paper will provide guidance to the Chinese firms to develop carbon disclosure policies and encourage researchers to conduct future research on this subject.

Carbon flow in forest products trade will affect the report of a country's carbon stock. This will have an impact on a country's contribution of carbon flows. Based on the analysis of China's forest product trade, this paper uses the stock-change approach, the production approach and the atmospheric-flow approach to calculate the changes of China's forest products trade carbon flows. Different carbon flow measurement approaches have very different results. From the perspective of the contribution of forest products to carbon flow, the production approach of calculation for forest products trade carbon flow has the largest contribution to atmospheric carbon flows. However, the calculation results of the stock-change approach and the atmospheric-flow approach are just the opposite, that is, the calculation for forest products trade has a negative contribution to China's carbon sinks, and forest products trade has become a source of carbon emissions.

This paper aims to analyze the trading mechanism of China pilot carbon emission trading market and figure out whether the current market price is rational and valid. By applying directional distance function and stochastic frontier analysis method, we estimated the CO2 marginal abatement cost of 92 coal-fueled generators belonging to 27 power plants located in Shanghai which is one of the pilot carbon emission trading market cities in China. The result indicates that the market price will greatly affect the trading activities within carbon emission trading market. We conclude that the current market price is not rational for coal-fueled power industry which is high-carbon and high CO2 MAC industry. When the exchange of nationwide carbon trading market formally start, policymakers should impose carbon tax or carbon emission quota to adjust the market price and stimulate the CO2 emission reduction willingness of coal-fueled power plants.

A reduction in the CO2 emission intensity (ton per gross domestic product) from a base year to a target year with different rates of reduction in each individual year can yield different cumulative CO2 emissions over time, which could have different effects on the climate. In this paper, an indicator is proposed to measure the extent to which the cumulative CO2 emissions are generated by a specific reduction trajectory of CO2 emission intensity, especially for emerging economies with a relatively higher economic growth rate. The proposed indicator is important for less-developed countries and regions in which economic growth is heavily reliant on energy and in which significant potential exists for improvement of energy efficiency. The indicator is applied to evaluate the CO2 emission reduction performance in China's 12th Five-Year Plan period, and the result is not encouraging, especially when the likely gap between the energy conservation goals and temperature goals is further examined. Mitigation goals should be set by considering not only the performance in the final year, but also the reduction in cumulative emissions over the evaluation period. [ABSTRACT FROM AUTHOR]

Nowadays, as China has become the factory of the world, China's industrial sectors have become the country's main source of energy consumption and emissions including CO2, SO2, NOx and soot. This article will use the non-radial directional dispersion function model (DDF) to explore ways to improve both the energy efficiency and the emission efficiency of China's industrial sectors. Based on current research, this article proposes a new projected input for the treatment of industrial waste gas, and optimizes the projected input and output settings. The data analysis shows that there is room for improvement in China's energy efficiency, and its regional imbalances have expanded. The Chinese government is urged to pay more attention to the improvement of energy efficiency in the central and western regions, and to provide more policy support. Simultaneously, the paper attemtps to establish measurement indexes to improve the efficiency of emission reduction. As a result, the authors suggest that increasing government expenditure can play a positive role in the overall improvement of emission reduction efficiency. [ABSTRACT FROM AUTHOR]

In the Paris Agreement, there are targets set up for 2100 to be well below 2 °C. A more ambitious target of 1.5 °C also appears in the agreement. In order to address whether this target is achievable or not, studies about the 1.5 °C target's emission pathway are essential. Recently a few studies have presented modelling results of the global emission pathway for the 1.5 °C target. This paper presents an analysis for China under the global 1.5 °C pathway and budget, by looking at key options to go beyond the 2 °C target pathway. Similar to the global emission pathway, China's CO2 emissions have to be reduced quickly and reach zero emission between 2050 and 2060. China's energy system needs to make a rapid transition to much greater reduction in fossil fuel use from now on. End-use sectors need to increase electricity use significantly. Power generation will achieve negative emission before 2050. CCS will be widely used, and biomass energy with CCS (BECCS) must be adopted on a large scale by 2040. This is doable in China, but very near-term changes in policy are needed to make such a pathway happen. [ABSTRACT FROM AUTHOR]

Evaluating the operational efficiency of emissions trading pilots has become a crucial task faced by China's emissions trading scheme in its stable transition from pilot programs in limited areas to a nationwide carbon trading market. A number of factors contribute to the difficulty of such evaluations, such as differences in system design, the absence of evaluation systems and the complexity of external factors. A study of the seven major carbon emissions trading pilots in China was conducted. In this paper, the institutional arrangements of carbon emissions trading pilots are differentiated based on six dimensions: distribution systems, flexible mechanisms, emissions control scope, transaction rules, reporting and verification systems, and legal systems. In addition, an evaluation index system is constructed to determine the input and output efficiency of the carbon emissions trading market. The Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method is used to calculate regional difference coefficients, revise the output index data, and effectively control the influence of the non-equilibrium external environment on efficiency. A Super Slack Based Model (Super-SBM) model is used to measure the operational efficiency of the carbon emissions trading market in the pilot area, and the results indicate that (1) for countries and regions with external environments facing uneven development, a differentiated system design should be developed; (2) the lack of changes in the overall ordering of the pilot efficiency demonstrates that institutional arrangements play a decisive role in the operational efficiency of China's carbon emissions trading market; and (3) none of the seven carbon emissions trading pilots has been operating effectively in China. The results indicate that a series of measures should be formulated, including the introduction of mechanisms for increasing quotas; increasing the flexibility of offsetting mechanisms; lowering the market access threshold; expanding the coverage of emissions control; training and restoring the professional monitoring reporting verification (MRV) ability; strengthening efforts associated within incentives and sanctions; and enhancing the legal enforcement of relevant policies.

Due to rapid urbanization and increasing energy consumption, human society poses increasing pressure on the surrounding ecosystems that it depends on. As a result, evaluation of urban development should view cities as complex ecosystems including human and natural elements. This paper establishes a carbon balance index (CBI) for an urban ecosystem based on its socio-economic development and land use and land cover change in Xiamen, a rapidly urbanizing coastal city in southeast China. Dynamic changes in CBI can quantitatively indicate the sustainability of the urbanization process from a carbon cycling perspective. Results show that Xiamen's carbon balance condition experienced three stages: the period 1987–2002 where CBI decreased slightly, 1992–2002 where CBI moderately increased from 1.4 to 4.2, and 2003–2011 where CBI rapidly increased from 5.2 to 17.3. The carbon imbalance increased with the expansion of urban scale and urbanization. By stepwise multiple regression analysis, it was found that the main influencing factors of CBI are urbanization rate, industrial coal consumption, length of roadway network and forest area, and city managers should take these factors into consideration to achieve low-carbon city development. Finally, the CBI for the year 2030 is predicted based on CO2emissions and sequestration scenarios. [ABSTRACT FROM AUTHOR]

With massive urbanization and infrastructure investments occurring in China, understanding GHG emissions from infrastructure use in small and large Chinese cities with different administrative levels is important for building future low-carbon cities. This paper identifies diverse data sources to assess GHG emission from community-wide infrastructure footprints (CIF) in four Chinese cities of varying population (1 to 20 million people) and administrative levels: Yixing, Qinhuangdao, Xiamen and Beijing.CIFaddresses seven infrastructure sectors providing energy (fuels/coal), electricity, water supply and wastewater treatment, transportation, municipal waste management, construction materials, and food to support urban activities. Industrial energy use dominates the infrastructure GHGCIFin all four cities, ranging from 76% of totalCIFin Yixing to 30% in Beijing, followed by residential energy use (6–13%), transportation (4–12%), commercial energy use (2–25%), food (6–11%), cement use (3–8%) and water (about 1%), thereby identifying priorities for low-carbon infrastructure development. Trans-boundary footprint contributions ranged from 31% (Beijing) to 8% (Qinhuangdao), indicating that supply chains to cities are important. GHGs from energy use are dominated by electricity (35–45%) and non-electricity coal use (30–50%). The authors demonstrate that disaggregated infrastructure use-efficiency metrics in each infrastructure sector provide useful baseline performance data for comparing diverse cities.
