It is generally acknowledged that human activities are leading to "global warming".. Carbon Dioxide is the most important of the greenhouse gases that are increasingly trapping solar heat and warming the global climate. Flying is the most carbon intensive way to travel. Aviation at present accounts for 3 % of greenhouse gases and generates nearly as much carbon dioxide in one year as the total population of Africa.

The calculator below gives an idea of how much you might donate to plant trees that will help soak up carbon or to support fuel efficiency projects. As trees in different parts of the world and in different conditions, assimilate carbon at different rates, this can only be a rough guide. The calculation is based upon how much carbon an acre of rainforest can soak up.
All of your donation will be donated to the projects outlined.
