To achieve 100% renewable electricity, companies must match 100% of the electricity used across their operations with electricity produced from renewable sources. These can include biomass (including biogas), geothermal, solar, water, and/or wind – either sourced from the market or self-produced.
Companies must meet certain requirements (i.e. size, sector) outlined in the RE100 joining criteria. The commitment includes all electricity that a company consumes (including self-generated electricity).
CE100 HK companies must select a target date for achieving 100% renewable electricity. The minimum requirements are:
100% by 2050, with interim steps of at least:
60% by 2030
90% by 2040
If a joining member company is already at 100% renewable electricity, they're invited to share the date they reached this achievement. In this case, and if the company has a year-on-year rolling target, its target year will be the reporting year.
The average target date for CE100 HK companies is 2028. No company should set a date later than 2050. Setting a 100% renewable electricity target by 2030 at the latest shows a strong level of leadership.
The target applies to all operations, but companies have the possibility to exclude from the scope of their target some small operations which have negligible impact on local demand, up to 100 MWh per market for a limited number of markets. The full details are available in our Materiality Threshold document.
This is a 2-3 month staged process outlined. Companies will be thoroughly assessed against the joining criteria. We carry out a due diligence process when a company applies to join CE100 HK. Where questions arise or issues of concern are identified, we may seek to discuss these with the company prior to determining eligibility.
Member companies must progress towards their 100% commitment in line with the RE100 criteria, contained in the following three documents:
A. Technical Criteria, which gives details on:
The technologies that we consider to be renewable;
The sourcing options we recognise (both self-generation and purchase options);
How to make credible unique use claims depending on the sourcing option chosen
B. Guidance on making credible renewable electricity usage claims, providing details on:
How renewable electricity claims are distinct from offsetting claims;
The attributes needed to claim renewable electricity usage;
The definition of a credible attribute tracking system – we have identified that I-REC (International) and TIGR (International) meet those criteri
Company progress towards 100% renewable electricity must be reported annually. Consumption and production of renewable electricity need to meet credibility and transparency requirements.
The data collected is published and provides the insights on corporate renewable electricity sourcing and aggregated demand, that drive and direct our policy work globally.
2022 Reporting Guidance can be found here.
Procuring renewable electricity in some markets is challenging and we recognise that corporate ambition to reach 100% may outpace availability in some areas.
If a company doesn't reach their 100% target because they can't make credible claims of renewable electricity use in a market, this is doesn't represent a failure of the company. Rather, it is an opportunity to use their influence in combination with other CE100 HK members and supporting organisations to advocate for market change.
If none of the sourcing options considered as credible in the CE100 HK criteria are available – including onsite self-generation – we recommend that:
companies communicate transparently and publicly on the barriers they face in those markets and countries, as their voices are powerful
companies engage with key stakeholders such as governments and energy companies to develop new options that suit their needs.
Renewable energy is a fast-evolving sector and we expect that all regions will have renewable energy sourcing options available in the near future.
