Fly less

Air travel produces large amounts of emissions so reducing how much you fly by even one or two trips a year can reduce your emissions significantly. You can also offset your air travel by investing in renewable energy projects.

Background Information
Aviation contributes to global warming in a number of ways, the most significant of which is the combustion of kerosene (a fossil fuel) in flight. Greenhouse gas emissions from ground airport vehicles and those used by passengers and staff to access airports also contribute, as do emissions generated by the production of energy used in airport buildings, the manufacture of aircraft and the construction of airport infrastructure.

The principal greenhouse gas emission from aircraft in flight is carbon dioxide (CO2), but other emissions include nitric oxide and nitrogen dioxide, (together termed oxides of nitrogen or NOx), water vapour and particulates (soot and sulfate particles). Other emissions include sulfur oxides, carbon monoxide, hydrocarbons and radicals such as hydroxyl.

The contribution of civil aircraft-in-flight to global CO2 emissions has been estimated at around 2%.[1] However, when non-CO2 altitude-sensitive effects are included, the total impact on anthropogenic (man-made) climate change is believed to be significantly higher. Moreover, that contribution is set to rise for the foreseeable future as increases in the volume of aircraft movement outpaces improvements in fuel efficiency.
