Established in 2014, the RE100 is an international coalition of major corporations committed to achieving 100% renewable energy.

The RE100 is administrated by charity the Climate Group, headquartered in London. The Climate Group’s major partner in founding the RE100 is the CDP, previously known as the Carbon Disclosure Project, a multi-national non-profit that have helped over 8,400 companies publicly disclose their sustainability performance since 2002.

When first founded, the group comprised just 13 companies, with an aim to reach 100 by 2020. That target was reached in 2017, three years ahead of schedule. Since then, membership has grown to 342 members at the time of writing (November 2021). 40 of those either have headquarters or significant operations in the UK, making up a total of over 9.7 million MWh of annual electricity consumption.

To join the RE100, an organisation must have an annual electricity demand of 100GWh, as well as making a public commitment to sourcing 100% of that electricity demand from renewable sources. They are expected to make a 60% reduction by 2030, reaching 90% by 2040 and becoming 100% renewable by 2050. This includes their entire operations including Scope 1 and Scope 2 emissions, as defined by the Greenhouse Gas Protocol.
