Luftfartens utslipp av CO2?

[77W]

Hei!

Noen som vil hjelpe meg med å finne ut ca. hvor mye luftfarten slipper ut CO2 årlig? Ønsker å se på saken med objektive øyne her.

Fra Eurocontrol:

Climate change is a change in the "average weather" that a given region experiences, including such factors as storm frequency, temperature, wind patterns and precipitation. The rate and magnitude of global climate changes over the long term have many implications for natural ecosystems. As society becomes increasingly reliant on energy consumption in work at home and for mobility, the heat-trapping nature of the atmosphere has increased. As our scientific understanding of this situation increases, so does public concern and the requirement for a policy response. Aviation contributes a small but growing proportion to this problem (less than 4% of man-made atmospheric emissions). A key factor however, is that some of aviation's emissions are emitted in the upper atmosphere and may have a more direct effect. The science of climate change is still relatively new and the future is uncertain. However, there is a broad consensus that policy needs to be enacted now if climate change related problems and costs are to be avoided.

How much CO2 are countries emitting? Where is it coming from?

In the lead-up to the UN climate negotiations in Cancún, the latest information on the level and growth of CO2 emissions, their source and geographic distribution will be essential to lay the foundation for a global agreement. To provide input to and support for the UN process the IEA is making available for free download the Highlights version of CO2 Emissions from Fuel Combustion.

This annual publication contains:

• estimates of CO2 emissions by country from 1971 to 2008
• selected indicators such as CO2/GDP, CO2/capita, CO2/TPES and CO2/kWh
• CO2 emissions from international marine and aviation bunkers, and other relevant information
