Cloud computing uses almost 2x as much power as the whole of the UK. These ratings show you the greenest place to send work right now.
These are the latest modelled CO2 emissions per hour for a m1.xlarge or equivalent for popular cloud locations. Our data and analysis are based on assumptions and represent opinions not facts. We aim to update our models as better data becomes available.
Use Customise to receive a personalised recommendation based on your preferred tradeoff between cost and emissions. Click on a location name to go directly to that provider.
