What’s Required

RE100 is a corporate initiative led by the Climate Group in partnership with CDP. It encourages companies to transition their electricity consumption to renewable energy sources.

Companies joining RE100 must commit to sourcing 100 percent renewable electricity across their global operations.

Members must establish a timeline for achieving the target. Many companies set milestone targets to progressively increase renewable electricity use.

Renewable electricity procurement may occur through several mechanisms. These include power purchase agreements, renewable energy certificates, on-site renewable generation and utility green tariffs.

Companies must track electricity consumption across all facilities and verify renewable energy sourcing through recognised certification systems.

Annual disclosure is required. Companies must report electricity consumption data, renewable energy sourcing percentages and procurement methods.

Companies must also provide transparency regarding market boundaries and explain how renewable electricity is accounted for across global operations.

RE100 guidance requires members to prioritise direct renewable energy procurement where possible to support new renewable generation capacity.

Important Deadlines

RE100 initiative launch: 2014

Members must publish renewable electricity targets within one year of joining.

Annual reporting is required.

Current Status

RE100 includes hundreds of multinational companies across sectors, including technology, retail, manufacturing, and finance.

The initiative continues to expand as companies adopt renewable energy procurement strategies.

Penalties for Non-Compliance

Companies failing to meet reporting obligations may lose membership status.

Failure to demonstrate credible progress toward renewable electricity targets may lead to removal from the initiative.

Examples of Known Violations

Common challenges include:

  • over-reliance on unbundled renewable energy certificates rather than direct renewable energy procurement.

  • incomplete disclosure of electricity consumption.

  • inconsistent accounting of renewable electricity across international operations

These issues may raise concerns about the credibility of renewable energy claims.
