Royal Society Carbon Trading site

The Royal Society was founded in 1660 and claims to be the oldest learned society still in existence.

Past presidents include Sir Isaac Newton and Joseph Banks.

They, in this more modern time, have created a site called Carbon Limited that looks at our use of Carbon more from the perpective of carbon rationing (a concept discussed by George Monbiot in his book Heat).

On this site you can deduce your carbon emisions, learn ways to reduce them, and compare them to other people. If we are to achieve a 90% reduction in Greenhouse gas emisions by 2030 (See Heat), then we will all have to be concious of this information.
