The coal-fired power industry in China is confronted with pressing local air pollution and CO2 control issues. This study explores the opportunity of co-controlling local air pollutants and CO2 in the context of the Chinese coal-fired power industry, with an integrated multi-pollutant co-control strategy decision-making framework. Reduction technologies and measures are evaluated through the use of unit costs of pollution reduction (UCPR), and the most cost-effective abatement routes are then designed. Our analysis shows that energy-saving technologies and structure-adjustment measures are the most favoured options in terms of co-control effectiveness and cost-effectiveness, while end-of-pipe control measures are the least preferred. Integrated multi-pollutant reduction co-control routes are more cost-effective (and desirable) than single-pollutant reduction routes, meaning that co-control strategies hold more potential in terms of multi-pollutant control effectiveness and monetary benefits. The sensitivity analysis verifies the robustness of the results to changing parameters. Although co-control strategies are attractive and effective, there are policy barriers to their implementation. Certain policy modifications should be enacted to promote co-control for the Chinese coal-fired power industry. © 2013 Elsevier Ltd. All rights reserved. Source

Extensive clearing of Indonesian primary forests results in increased greenhouse gas emissions and biodiversity loss. However, there is no consensus on the areal extent and temporal trends of primary forest clearing in Indonesia. Here we report a spatially and temporally explicit quantification of Indonesian primary forest loss, which totalled over 6.02 Mha from 2000 to 2012 and increased on average by 47,600 ha per year. By 2012, annual primary forest loss in Indonesia was estimated to be higher than in Brazil (0.84 Mha and 0.46 Mha, respectively). Proportional loss of primary forests in wetland landforms increased and almost all clearing of primary forests occurred within degraded types, meaning logging preceded conversion processes. Loss within official forest land uses that restrict or prohibit clearing totalled 40% of all loss within national forest land. The increasing loss of Indonesian primary forests has significant implications for climate change mitigation and biodiversity conservation efforts. © 2014 Macmillan Publishers Limited.

The present study proposes an integrated multipollutant cocontrol strategy framework in the context of the Chinese iron and steel industry. The unit cost of pollutant reduction (UCPR) was used to examine the cost-effectiveness of each emission reduction measure. The marginal abatement cost (MAC) curves for SO2, NOx, PM2.5, and CO2 were drawn based on the UCPR and the abatement potential. Air pollutant equivalence (APeq) captures the nature of the damage value-weights of various air pollutants and acts as uniformization multiple air pollutants index. Single pollutant abatement routes designed in accordance with the corresponding reduction targets revealed that the cocontrol strategy has promising potential. Moreover, with the same reduction cost limitations as the single pollutant abatement routes, the multipollutant cocontrol routes are able to obtain more desirable pollution reduction and health benefits. Co-control strategy generally shows cost-effective advantage over single-pollutant abatement strategy. The results are robust to changing parameters according to sensitivity analysis. Co-control strategy would be an important step to achieve energy/carbon intensity targets and pollution control targets in China. Though cocontrol strategy has got some traction in policy debates, there are barriers to integrate it into policy making in the near future in China. © 2013 American Chemical Society. Source
