In June 2014, the United States Environmental Protection Agency (EPA) issued proposed greenhouse gas regulations called the Clean Power Plan. Because of opposition in the U.S. Congress to enacting legislation to limit greenhouse gas emissions, EPA used its existing regulatory authority under the Clean Air Act to put forth this proposal. The EPA expects the plan w...
Half of Americans live in areas violating national health-based air quality standards. Coal- and gas-fired power plants are important contributors to the problem. The Clean Air Act has historically addressed power plants through regulation of smokestack emissions, employing “stovepiped,” pollutant-by-pollutant control strategies. Air quality has improved, but...
Air quality officials have significant new opportunities to ensure that air pollution issues are considered in the course of electricity system planning as a result of FERC Order 1000, Transmission Planning and Cost Allocation by Transmission Owning and Operating Public Utilities. This article outlines the importance of FERC Order 1000 to state, local, and tribal...
Coal continues to be the dominant fuel choice for power generation around the world. How that coal is burned can influence the rate and quantity of emissions produced by its combustion. For decades, many countries have established standards and specifications for the quality of coal purchased. Doing so has enabled power plant owners to reduce operating and mainte...
Regulators, advocates, and energy industry companies have long understood that energy efficiency policies and programs can reduce air pollution emissions associated with fuel combustion. This reduction in emissions can lead to lower environmental compliance costs and, ultimately, lower public health costs. However, translating concrete energy efficiency policy in...
在世界范围内，煤炭仍然是发电的主导燃料。煤炭的燃烧方式影响着污染物的排放率和总排放量。几十年来，许多国家为煤炭质量制订了一系列标准和细则，使得电厂经营者减少了运行和维护成本，改善了锅炉的热效率。高效率意味着同样发电量需要的煤炭投入减少，降低了�...
中国清洁空气联盟（CAAC）知识系列之一“空气污染应急机制国际经验”在回顾了中国2013年1月大面积遭遇灰霾天气而采取的应急方案之后，介绍了欧洲和美国污染应急领域所开展的工作和历程，并结合中国的空气污染情况为中国构建空气污染应急机制提出了建议。文中从空气�...
IMPEAQ is RAP’s initial effort to develop a model process that states, local agencies, and EPA can apply to comprehensively and simultaneously reduce all air pollutants, including criteria, toxic, and greenhouse gases (GHGs). IMPEAQ seeks to identify least-cost pathways to reduce emissions of multiple pollutants by adhering to Integrated Resource Plan (IRP) pri...
