Launched during Climate Week NYC 2014, the mission of RE100 is to accelerate the change to zero carbon emissions by 2040 through the use of renewable electricity (biomass including biogas, geothermal, solar, water or wind). RE100 provides companies with access to peer-learning, policy support, and local market insight. The initiative operates in Europe, North America, the Asia-Pacific and Japan.

What is the RE100?

RE100 is the global corporate renewable energy imitative bringing together hundreds of large and ambitious businesses committed to 100% renewable electricity. It is an initiative led by The Climate Group ( and CDP ( 

RE100 members look to policymakers to enact the following policy measures to support corporate sourcing of renewable energy: 

  1. Create a level playing field on which renewable electricity competes fairly with fossil-fuel electricity and reflects the cost-competitiveness of renewable electricity
  2. Remove regulatory barriers and implement stable frameworks to facilitate the uptake of corporate renewable electricity sourcing. 
  3. Create an electricity market structure that allows for direct trade between corporate buyers of all sizes and renewable electricity suppliers. 
  4. Work with utilities or electricity suppliers to provide options for corporate renewable electricity sourcing. 
  5. Promote direct investments in on-site and off-site renewable electricity projects
  6. Support a credible and transparent system for issuing, tracking and certifying competitively priced Environmental Attribute Certificates (EACs).

How can a company join the RE100?

Companies (currently 268) must meet a set of criteria to become members ( of RE100 – see:


RE100, the Climate Group and CDP are three more organisations/initiatives (amongst a growing cadre of such) that see themselves as driving the push towards carbon neutrality by 2050. Whilst there does not appear to be anything to give any particular cause for concern, the bigger question is whether the current garden has a thousand flowers blooming or whether it has a weed problem. The proof, no doubt, will come in the pudding.
