Do You Know Your Carbon Footprint?

The problems and interactivities in this feature will allow you to explore the impact of your lifestyle choices and help you to gain a better understanding of the contributors to global emissions.

Numbers to do with carbon emissions occur again and again in the public space, and we hope that these activities will help you to understand and compare them.
