This widget will help you estimate your personal annual CO2 emissions. It is estimated that the sustainable CO2 emission quota per capita for each of 6 billion global inhabitants is 2 tonnes per annum. Until this target has been reached we continue to accelerate the rate of climate change, so anyone who attempts to reach this target is providing a great service and example. Good luck!
The total tonnage of carbon should then be multiplied by $7 to arrive at the donation amount.
