The emission factor of 95 Mg CO2 ha-1 yr-1 used by the EPA was based on a peat subsidence study, rather than on carbon stock change measurement. This value was more than twice as high as the average annual emission rate of 38 Mg CO2 ha-1 yr-1 based on direct CO2 flux mea...

US Epa 被引量: 26发表: 2007年 Comparison of US EPA and European emission standards for combustion and incineration technologies There has been considerable debate, misunderstanding, and controversy when comparing emission standards used in Europe and the United States. One of the fi... A Licata,...
the EPA said. The proposals would improve air quality for communities across the nation, avoiding nearly 10 billion tons of carbon dioxide emissions by 2055, more than twice the total U.S. CO2
AP - 42 ( Compilation of Air Pollutant Emission Factors )是美国国家环保局( USEPA )编写的大气污染物排放系数汇编,涵盖了固定燃烧源、内燃机和无组织排放等各个方面,是估算排放量、建立排放清单的常用参考工具。在 EPA 的网站上可以免费下载。查 AP - 42 中 1.1 Bituminous And Subbituminous Coal Combustion ...
The Biden administration is proposing stiff new automobile pollution limits that would require up to two-thirds of new vehicles sold in the U.S. to be electric by 2032, a nearly tenfold increase over current electric vehicle ...
The finalized regulations are the "strongest national greenhouse gas standards for heavy-duty vehicles in history," EPA chief Michael Regan said. Under the measures, vehicle manufacturers will have the flexibility to choose which set of emission control technologies they want to use, with options inc...
(considering a low-emission scenario: SSP1-1.9) and presents a greater concern for the region than geocentric sea-level change (considering a high-emission scenario: SSP5-8.5) to 2045 (Extended Data Fig.5d) and 2070 (Extended Data Fig.5e,f), assuming linearly continuous subsidence. This ...
Since airline makers globally are expected to follow the new international standards anyway, “the EPA is not projecting emission reductions associated with today’s proposed GHG regulations,” or greenhouse gas rules, the EPA description of the change notes. Before the COVID-19 outbreak h...
We continue to win with the winners and have secured new vehicle platforms associated with the 2027 U.S. EPA emission standards. We are leaders in fuel filtration and crankcase ventilation. These continued wins further demonstrate our ability to support customers and provide our industry-leading Fle...
