Greenhouse gas intensity of national economies Greenhouse gas intensity of national economies
The national greenhouse gas intensity measures the quantity of GHG emissions in relation to the economic output of a country and is independent of the absolute quantity of GHG emitted.

Norwegian emissions of SF6 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.

Emissions of HFC in CO2 equivalents in Norway, 85-96 Emissions of HFC in CO2 equivalents in Norway, 85-96
The graphic shows Emissions of HFC in CO2 equivalents in Norway from 1985 to 1996 with projections to 2010. HFCs are among the most important greenhouse gases and are covered under the Kyoto protocol. Hydrofluorocarbons (HFC's) do not harm or breakdown the ozone molecule, but they do trap heat in the atmosphere, making it a greenhouse gas, aiding in global warming. HFC’s are used in air conditioners and refrigerators.

Norwegian emissions of N2O Norwegian emissions of N2O
Emissions of N20 have a role in the enhanced greenhouse effect. N20 is a long-lived gas, surviving in the atmosphere for about 130 years. The concentration of N20 in the atmosphere is increasing due to a variety of sources including a small contribution from coal combustion.

Potential climate change impacts Potential climate change impacts
If greenhouse gas concentrations keep rising, climatic changes are likely to result. Those changes will potentially have wide-ranging effects on the environment and socio-economic and related sectors, such as health, agriculture, forests, water resources, coastal areas and biodiversity.

IPCC and UNFCCC - Institutional framework IPCC and UNFCCC - Institutional framework
In 1988, UNEP and WMO jointly established the Intergovernmental Panel on Climate Change (IPCC) as concern over changes in the climate became a political issue. The purpose of the IPCC was to assess the state of knowledge on the various aspects of climate change including science, environmental and socio-economic impacts and response strategies. The IPCC is recognized as the most authoritative scientific and technical voice on these issues, and it...

Greenhouse effect Greenhouse effect
Human activities are causing greenhouse gas levels in the atmosphere to increase. This graphic explains how solar energy is absorbed by the earth's surface, causing the earth to warm and to emit infrared radiation. The greenhouse gases then trap the infrared radiation, thus warming the atmosphere.

Kyoto protocol, 2002 target status Kyoto protocol, 2002 target status
Target reached in 2002, but the emissions are increasing again. By the end of 2005, countries that are obliged to reduce their greenhouse gas emissions shall report on their progress towards reaching the emission targets set in the Protocol. Even if the total emissions from Annex 1 countries decreased by 6,4 % between 1990 and 2002, only a few of these countries can report on a real progress in reaching their emission targets. The decrease is mai...

Cooling factors Cooling factors
The amount of aerosols in the air has direct effect on the amount of solar radiation hitting the Earth's surface. Aerosols may have significant local or regional impact on temperature. Water vapour is a greenhouse gas, but at the same time the upper white surface of clouds reflects solar radiation back into space. Albedo - reflections of solar radiation from surfaces on the Earth - creates difficulties in exact calculations. If e.g. the polar ice...

Kyoto protocol, timeline and history Kyoto protocol, timeline and history
The Kyoto Protocol In 1997 world leaders adopted the Kyoto Protocol requiring rich countries to reduce their greenhouse gas emissions to 5.2% below the 1990 level, calculated as an average over the period 2008-2012. Under the Kyoto Protocol the rich countries have different targets, that in sum adds up to a reduction of 5.2%. For example, the European Union aims for an 8% cut in total, Germany committed to a 21% cut and the United Kingdom to 12.5...
