Energy productivity is the ratio of economic output to energy consumption. By implementing efficiency measures, EP100 members improve their energy productivity and reduce greenhouse gas (GHG) emissions. There are three commitments companies can choose from: 

• Double Energy Productivity: A company commits to doubling its economic output from every unit of energy it consumes globally within 25 years, with a baseline year of 2005 at the earliest. 
• Implement an Energy Management System: A company commits to implementing an energy management system (EnMS) in each of its facilities within 10 years and commits to an energy productivity target. 
• Net Zero Carbon Buildings: A company commits to owning, occupying and developing buildings that operate at net zero carbon emissions by 2030. A net zero carbon building reduces energy demand, is highly energy efficient and is fully powered by renewable electricity. This commitment is led by the World Green Building Council, and gives insight to a company’s emissions, energy demand reductions, and renewable energy solutions from an asset and portfolio level.

The EP100 is run by The Climate Group.
