RE100 is a collaborative, global initiative of influential businesses committed to 100% renewable electricity, working to massively increase demand for – and delivery of – renewable energy. 101 RE100 companies have made a commitment to go ‘100% renewable’ and have set a public goal to procure 100% of their electricity from renewable sources of energy by a specified year.
The RE100 has published a technical briefing, making credible renewable electricity usage claims. The technical briefing is described on the RE100 website as, “…a technical deep-dive into corporate transparency and credibility, and shows companies how to accurately describe their use of renewable electricity.” Companies increasingly purchase renewable electricity in order to claim the use of low or zero-emissions electricity and thereby reduce their carbon footprint.
Most renewable electricity sources/technologies, including wind, solar, geothermal, hydropower, ocean, and others, do not directly emit GHGs to generate electricity. Renewable electricity procurement therefore allows the consumer to claim to be using zero-carbon electricity, and thereby reduce the portion of their carbon footprint associated with purchased electricity. The emissions associated with purchased electricity are categorized as “Scope 2” in the Greenhouse Gas Protocol Corporate Standard.
