Top 10 CO2 emitting countries in 2000; Latin America and the Caribbean
Brazil is the world’s second largest emitter of carbon dioxide (CO2) from land use change. Only Indonesia emits more. In 2000 CO2 emissions from land use change in Brazil represented 18% of the world’s total emissions. ...

Tropical hydropower dams as greenhouse sources
Large tropical hydropower reservoirs in Latin America may have a potential adverse impact on the climatic system through releasing greenhouse gases into the atmosphere. Submerging large areas of land and tropical vegetat...

Global atmospheric concentration of CO2
Atmospheric CO2 has increased from a pre-industrial concentration of about 280 ppmv to about 367 ppmv at present (ppmv= parts per million by volume). CO2 concentration data from before 1958 are from ice core measurements...

Planets and atmospheres
A planet's climate is decided by its mass, its distance from the sun and the composition of its atmosphere. Mars is too small to keep a thick atmosphere. Its atmosphere consists mainly of carbon dioxide, but the atmosphe...

CO2 emissions from land use change
Emissions of carbon dioxide due to changes in land use mainly come from the cutting down of forests and instead using the land for agriculture or built-up areas, urbanisation, roads etc. When large areas of rain forests ...

Emissions due to solid waste disposal on land
Landfi ling is the most common waste management practice, and results in the release of methane from the anaerobic decomposition of organic materials. Methane is around 20 times more potent as a GHG than carbon dioxide. ...

Contribution of various waste management systems to greenhouse gas emissions, 2002
The disposal and treatment of waste can produce emissions of several greenhouse gases (GHGs), which contribute to global climate change. The most significant GHG gas produced from waste is methane. It is released during ...

Emissions of CO2 per capita 1990 (selected countries)
The graph shows emissions of CO2 per capita 1990. CO2 can be emitted as byproduct from the use of fossil fuel, by combustion, land-use conversion and cement production. Atmospheric concentrations of CO2 are increasing, a...

Global atmospheric concentration of CO2 1870-1990
Historically the developed countries of the world have emitted most of the anthropogenic greenhouse gases. The U.S. emits most in total, and is one of the countries with highest emissions per capita. China is the second ...

CO2 emissions from industrial processes and land use change
2 thematical maps: (1) CO2 emissions from industrial processes (http://www.grida.no/climate/vital/09.htm): This map depicts the unequal distribution of industry in the world. The significant part of carbon dioxide emiss...

Atmospheric concentrations of carbon dioxide (CO2) - Mauna Loa or Keeling curve
Atmospheric concentration of CO2 is steadily rising, and oceans directly assimilate CO2. As ocean concentration of CO2 increases, the oceans automatically become more acidic. This, in turn, may have severe impacts on co...

Total CO2 emissions
From fossil-fuel burning, cement production and gas flaring. Country size is proportionate to national carbon dioxide emissions in 2004.

Energy consumption by usage in a building
Buildings (residential and commercial) account for 10 to 15% of all greenhouse gas emissions, including almost 70% carbon dioxide and 25% methane.

Emissions of CO2 in Norway, 85-95
The graph shows emissions of CO2 in Norway from 1985 to 1995 and estimates future emissions from 1995 to 2010. CO2 can be created by use of fossil fuel, by land-use convertion, combustion or cement production.

Norwegian emissions of SF6
SF6 is a gas that is used in circuit breakers and other switchgear as an electrical insulator. SF6 is a highly potent greenhouse gas, over 23,900 times more effective at trapping infrared radiation than carbon dioxide.

Norwegian emissions of CO2
Emissions of carbon dioxide in Norway, 1985-1997, with projections up to 2010 (with a current measures scenario, as of 1997). Carbon Dioxide (CO2) is the main agent of greenhouse gases that is released primarily from the...

CO2 emissions from industry
This map depicts the unequal distribution of industry in the world. The significant part of carbon dioxide emissions comes from energy production, industrial processes and transport. The industrialised countries conseque...
