Renewable Energy


To stay below a maximum 1.5/2°C global average temperature rise, doubling the share of renewable energy by 2030 is essential. Renewable energies such as solar, wind and geothermal are getting progressively cheaper and more effective, and have the most impact when coupled with measure to boost energy efficiency.

Website: RE100

RE100 is an ambitious, global initiative to engage, support and showcase major companies that have committed to using 100% renewable power, inspiring leadership in the fight against climate change and in the development of a low-carbon economy.

According to the UN’s Intergovernmental Panel on Climate Change, the internationally agreed goal of a maximum 2 degrees Celsius global average temperature rise is only possible if renewable energy is swiftly and massively scaled up.

Many companies recognize the need for climate action and know that switching to renewable electricity will help them to deliver on their carbon reduction goals. They also benefit from lowering energy security risk, and making long-term financial savings.

RE100 was launched at Climate Week NYC in 2014 with 13 major companies, from furniture manufacturer IKEA to insurer Swiss Re. It has grown notably in number and scope, with new businesses from a variety of industrial sectors joining from around the world. In 2015, the first Chinese and Indian companies joined what is becoming a truly global campaign.

With electricity accounting for over 25% of global greenhouse gas emissions, and the IEA forecasting that its demand will grow significantly by 2040, the ultimate goal of RE100 is to switch this demand to renewable sources of energy rather than fossil fuels – ensuring that net zero emissions are reached well before the end of the century.

RE100 is part of the Lima-Paris Action Agenda (LPAA) and is spearheaded by The Climate Group in partnership with CDP.

How RE100 works – Criteria for Reaching the 100 Per Cent Goal

The initiative helps companies gain a better understanding of the advantages of going 100% renewable, promotes peer-to-peer learning, and provides public recognition of their ambitions and achievements as they work towards the 100% renewable goal.

RE100 considers renewable the electricity generated from biomass (including biogas), geothermal, solar, water and wind energy sources.

In order to determine that a company has truly reached its target of 100% renewable energy, it must fulfil the “RE100 Criteria”.

The initiative’s Technical Working Group studies the environmental and social sustainability of these technologies and may introduce related recommendations and criteria.

Options for Renewable Energy

To achieve 100% renewable electricity, a company may choose from the following options:

A)    On-site electricity generation through:                    

  • direct consumption from on-site installations owned by the company or
  • purchase from on-site installations owned by a third party

B)    Off-site electricity generation through

  • direct line to an off-site generator with no grid transfer
  • direct procurement from a grid-connected generator
  • a contract with suppliers (green electricity products)
  • purchase of certificates of energy attributes
