The petitioners argued that carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and hydrofluorocarbons meet the definition of an air pollutant under section 302(g) of the Act, and that statements made by the EPA, other federal agencies, and the United Nations Intergovernmental Panel on Climate Change (IPCC) amounted to a finding that ...
Correcting to a reference carbon dioxide content [ edit ] The following equation can be used to correct a measured pollutant concentration in an emitted gas (containing a measured CO 2 content) to an equivalent pollutant concentration in an emitted gas containing a specified reference amount of CO 2 : [ 5 ]
The Regional Greenhouse Gas Initiative (RGGI, pronounced "Reggie") is the first mandatory market-based program to reduce greenhouse gas emissions by the United States.RGGI is a cooperative effort among the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont, and Virginia to cap and reduce carbon dioxide (CO 2) emissions ...
Concentrations in ppm of the major greenhouse gases between 1978 and 2010. Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry.
The new methane rule will help ensure that the United States meets a goal set by more than 100 nations to cut methane emissions by 30% by 2030 from 2020 levels, Regan said.
This is an accepted version of this page This is the latest accepted revision, reviewed on 13 February 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Fugitive gas emissions are emissions of gas (typically natural gas, which contains methane) to atmosphere or groundwater [1] which result from oil and gas or coal mining activity. [2] In 2016, these emissions, when converted to their equivalent impact of carbon dioxide , accounted for 5.8% of all global greenhouse gas emissions .
Gov. Glenn Youngkin announced Wednesday that Virginia will abandon California's stringent vehicle emissions rules aimed at reducing carbon pollution at the end of the year when that state’s ...
