RAcc’s Impact on Global Renewables if Adoption Scales

The analysis finds that if approximately 2,430 large companies (consuming over 100 GWh/year) adopted the RAcc model, the resulting demand would cover about 66% of global commercial and industrial electricity consumption and avoid 5.5 billion tCO2e annually. The report identifies a tipping point where adoption by the top 20% of these companies (~539 organizations) would exceed existing global renewable energy supply, necessitating the construction of new renewable generation capacity.

• Widespread adoption of the RAcc program by nearly 2,500 large companies that consume more than 100 GWh/year and report to CDP could result in renewable energy demand covering approximately 66% of global commercial and industrial (C&I) electricity consumption, avoiding roughly 5.5 billion tCO2e every year.
• A tipping point for the need for new renewable energy capacity is reached if the top 20% of large companies (approximately 539 organizations with more than 1 TWh of annual demand) adopt RAcc, as their procurement would likely surpass the current supply of RE100-eligible renewable electricity.
• The RAcc model shifts renewable procurement from isolated transactions to a coordinated global strategy, allowing large, credit-worthy buyers to source energy for their entire value chain. For Mars, this increases its potential renewable electricity customer profile from 2 TWh (own factories, offices, and clinics) to 8–9 TWh by including value chain demand.
• The analysis utilized a "RAcc multiplier" based on Mars's experience, assuming a company's value chain electricity demand is three times its own Scope 2 load. This resulted in an estimated total demand of 12,000 TWh (9,000 TWh from value chains and 3,000 TWh from Scope 2) if scaled across the identified large companies.
