About

The website

This website was launched in 2007 to give unbiased information on climate change, carbon dioxide and other greenhouse gas emissions, and how to become independent of fossil fuels. The calculator is constructed according to the best information available, and will be updated as new information becomes available.

The stance of this website is that of a policy scientist. This means

• the aim is to work towards a robust evidence-based consensus of reasonable people on any policy question
• the starting point is an open mind and impartiality
• using scientific methods and agreed principles of policy making (including human rights)
• as a contribution to society's decision making process
• aspiring to be a reliable, trusted source of information.
