Here's more info on joining EP100 and what it means to be an EP100 member.

Meeting the joining criteria

Companies must meet certain requirements (i.e. size, sector) outlined in the EP100 joining criteria.

Choosing an ambitious EP100 target

Companies must set an ambitious energy efficiency target by making one (or more) of the following commitments:

  • Double Energy Productivity: A company commits to double its economic output from every unit of energy it consumes globally within at least 25 years, from a fixed baseline year no earlier than 2005. The company chooses a relevant energy productivity metric (e.g. units of product/gigawatts (GW); full time employees/megawatt hours (MWh)) to track and report progress. See the detailed commitment criteria for more information.
  • Implement an Energy Management System: A company commits to implementing an EnMS globally across its operations within at least 10 years. The company also commits to an energy efficiency improvement target and chooses a relevant energy productivity metric. See the detailed commitment criteria for more information.
  • Net Zero Carbon Buildings Commitment: A company commits to occupy, own, or develop net zero carbon operational assets by 2030. The company also commits to maximise the reduction of embodied carbon in new developments or major renovations, compensating for any residual upfront embodied carbon emissions at point of practical completion of the project. Climate group runs this pathway in collaboration with the World Green Building CouncilSee here for more information on EP100 and the Net Zero Carbon Commitment.

Applying for EP100 membership

This is a staged process, outlined here. Companies will be thoroughly assessed against the joining criteria to determine eligibility and we will carry out a due diligence process.  Where questions arise or issues of concern are identified, we may seek to discuss these with the company prior to determining eligibility. 

Once eligibility has been established and the application has been accepted, communication of the joining announcement will be agreed with Climate Group.

Implementing energy efficiency solutions

Tap into the huge potential of energy efficiency:

Invest in energy efficiency improvements across your company's operations by installing highly efficient technologies, making organisational changes, incentivising behaviour change and more. Make the most of every unit of energy your company consumes to make progress against your EP100 commitment.

Share your journey with us:

We share the compelling business case for better energy efficiency; encourage knowledge-sharing and peer-learning through member-exclusive webinars and events; and showcase member leadership by offering speaking slots at key events and through digital media and media outreach. To do this, we need your energy efficiency stories.


Reporting progress annually

All EP100 companies must report annually on their progress towards achieving their EP100 target. Companies report in two different ways depending on their chosen commitment:

  • Double Energy Productivity & Implement an Energy Management System: Companies must report directly to us using our EP100 reporting form on an annual basis. Companies must report company-level total economic output and total energy consumption data, broken down by fuel type, starting from the baseline year. Insight on the drivers and barriers to achieving energy efficiency improvements and examples of successful implementation are welcomed.
  • Net Zero Carbon Buildings Commitment: Companies must report to the World Green Building Council using their Net Zero Carbon Buildings Commitment reporting form on an annual basis. Companies must report their annual asset and portfolio energy demand and carbon emissions.

The data are published in our annual EP100 Progress and Insights Reports and provide us with information on the drivers of, and barriers to, corporate energy efficiency action. Your data is crucial in helping us guide our strategic work.

Communicating the barriers faced

Implementing energy efficiency solutions in some markets is challenging and we recognise that corporate ambition may outpace feasibility in some areas.

If a company is struggling to achieve their target because cost-effective solutions have been exhausted, this doesn't represent a failure of the company. Rather, it is an opportunity to use their influence in combination with other EP100 members and supporting organisations to advocate for market change.

Once cost-effective energy efficiency solutions are being / have been exhausted, we recommend that:

  • Companies communicate transparently and publicly on the barriers they face in those markets and countries, as their voices are powerful.
  • Companies operating in the country come together to discuss shared barriers and to develop a solution. We exist to support this process and are happy to discuss opportunities to connect members in markets where ambitious energy efficiency improvements are particularly challenging.
  • Companies engage with key stakeholders such as governments and financial institutions to develop new options that suit their needs.
