How do I become an EP100 member?

If you're interested in joining EP100, this joining process diagram details the steps.

Please also make sure to read our key documents:

Please contact [email protected] if you have any further clarification questions for us.

Step 1: Meet the joining criteria

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

Step 2: Set 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 doubling its economic output from every unit of energy it consumes globally within 25 years or less, relative to a baseline year that is no earlier than 10 years prior to their joining date. See the detailed commitment criteria for more information.
  • Implement an Energy Management System: A company commits to implementing an energy management system (EnMS) globally across their operations within 10 years or less from joining; and, commits to an energy productivity percentage improvement target to be achieved within 25 years or less, relative to a baseline year that is no earlier than 10 years prior to their joining date. See the detailed commitment criteria for more information.
  • Net Zero Carbon Buildings Commitment: A company commits to owning, occupying and/or developing buildings that are net zero in operational and embodied 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 into a company’s emissions, energy demand reductions, and renewable energy solutions from an asset and portfolio level. See here for more information.

Step 3: Apply for EP100 membership

This is 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.

Step 4: Implement 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.


Step 5: Report 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 EnMS: 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. Further information is available here.

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.

Step 6: Communicate transparently on 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.
