The Global Calculator is a free and interactive model of the world's energy, land and food systems that allows users to explore the options for reducing global emissions to 2050. The tool shows that it is possible for people’s lifestyles to improve and for us to limit climate change to 2°C. However, to do this we must transform the technologies and fuels we use, and make smarter use of our limited land resources. Visit www.globalcalculator.org to read the full report, and to use the tool yourself. Why not create your vision of the future and share it on Twitter?

The Calculator is funded by the UK Government's International Climate Fund and the EU's Climate-KIC, and has been built by experts from Europe, China, India and the USA.
