Greenhouse gas emissions by China - Wikipedia

Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal electricity generation and mining. When measuring production-based emissions, China emitted over 12 gigatonnes CO2eq of greenhouse gases in 2014; almost 30% of the world total. This corresponds to over 7 tonnes CO2eq emitted per person each year, slightly over the world average and the EU average but less than half the second largest emitter of greenhoGet price

ChinaGreenhouse Gas Emissions - Skeptical Science

CFC-11 EmissionsPromoting CoalConsequencesCounter ActionThe 1987 Montreal Protocol has been signed by China and 197 other countries. The Protocol commits all countries to abolish production and use of ozone depleting halocarbon gasses to zero by 2010 because they destroy the ozone layerwhich protects the earths surface from harmful ultra violet radiation. Halocarbonsare also very powerful greenhouse gasses, particularly CFC-11 which has a lifetimein the atmosphere of 45 years or more The Kigali Amendment (2016) further requires phase-down of all hydrofluorocarbon gasses which have a greenhouse effect, some of which can be used as a substitute for halocarbons. If all countries had complied with the Montreal Protocol, it should have been expected that global CFC-11 emissions would have fallen sharply after 1995 when developed countries were required to reduce their production and use and to zero by 2010 when all other countries ceased production. However, as show in Fig. 1, this is not what has happened. Fig. 1. Decline in CFC-11 emissions...Get price

Global Greenhouse Gas Emissions Data | US EPA

Global Emissions by GasGlobal Emissions by Economic SectorTrends in Global EmissionsEmissions by CountryAt the global scale, the key greenhouse gases emitted by human activities are: 1. Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture, and degradation of soils. Likewise, land can also remove CO2from the atmosphere through reforestation, improvement of soils, and other activities. 2. Methane (CH4): Agricultural activities, waste management, energy use, and biomass burning all contribute to CH4emissions. 3. Nitrous oxide (N2O): Agricultural activities, such as fertilizer use, are the primary source of N2O emissions. Fossil fuel combustion also generates N2O. 4. Fluorinated gases (F-gases): Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (sf 6).

The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases). (Draft estimates for emissions of HFC and PFC substitutes for ozone-depleting substances in 2009 are included; 2008 data are used for emissions of other high-GWP gases.)

Impacts of Climate ChangeRoe IndicatorsReferencesThe changing climate affects society and ecosystems in a variety of ways. For instance: 1. A warmer climate is expected to both increase the risk of heat-related illnesses and deaths and increase certain types of air pollution. 2. More severe heat waves, floods, and droughts are expected in a warmer climate. These may reduce crop yields. 3. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. 4. Climate change can alter where species live and how they interact, which could fundamentally transform current ecosystems. These and other aspects of climate change are disrupting peoplelives and damaging some sectors of the U.S. economy.4This has led many state and local governments to prepare for these impacts through “adaptation” (i.e., planning for the changes that are expected to occur).

Greenhouse gas - Methane | Britannica

Greenhouse gas - Greenhouse gas - Methane: Methane (CH4) is the second most important greenhouse gas. CH4 is more potent than CO2 because the radiative forcing produced per molecule is greater. In addition, the infrared window is less saturated in the range of wavelengths of radiation absorbed by CH4, so more molecules may fill in the region. However, CH4 exists in far lower concentrationsGet price
