RE 100

What is RE100?

RE100 is a global initiative that brings together companies committed to sourcing 100% of their electricity from renewable energy. Led by The Climate Group in partnership with CDP, member companies set time-bound targets to transition from fossil-fuel-based electricity to clean sources like solar, wind, and hydro, while following transparent reporting and procurement standards.

In simple terms, the RE100 meaning refers to a business commitment to run entirely on renewable power.

Importance of RE100

RE100 is important because it:

• Drives large-scale corporate demand for renewable energy, accelerating clean power capacity addition
• Helps reduce indirect (Scope 2) emissions linked to electricity consumption
• Encourages long-term investments through mechanisms like power purchase agreements (PPAs)
• Supports global and national climate targets, including net-zero commitments
• Promotes transparency through standardised reporting and accountability frameworks
• Strengthens energy security by reducing reliance on fossil-fuel-based electricity
• Influences supply chains, encouraging partners and vendors to adopt renewable energy
• Improves corporate resilience against energy price volatility and regulatory risks

Uses of RE100 commit

RE100 commitments are used by organisations to:

• Transition electricity consumption to 100% renewable sources across operations
• Procure clean energy through on-site solar, PPAs, green tariffs, or renewable certificates
• Meet ESG, sustainability, and carbon reduction targets
• Reduce exposure to fossil fuel price volatility and regulatory risks
• Improve brand positioning and stakeholder confidence
• Drive renewable energy adoption across supply chains and business ecosystems

Examples of RE100

Some practical examples include:

• Companies installing rooftop solar across offices, factories, and campuses
• Businesses signing long-term solar or wind PPAs to secure renewable electricity
• Corporates sourcing green power through utilities or power exchanges
• Organisations using renewable energy certificates (RECs) to meet part of their targets
• Global and Indian companies committing to 100% renewable electricity under RE100
