Why it's on ClimateTicker

Sunrun is the largest U.S. residential solar and battery storage provider, with a core business model that genuinely displaces fossil-fuel grid electricity at scale — since 2007 its systems have helped avoid an estimated 18 million metric tons of CO₂. However, its 'clean energy' marketing must be weighed against a real Scope 3 footprint (~871 million kg CO₂e in 2024, dominated by panel manufacturing supply chains), a 2024 AG lawsuit over deceptive sales practices, and the fact that its avoided-emissions figures are self-reported estimates, not independently verified reductions. The SBTi validation of its net-zero and near-term targets (August 2024) meaningfully elevates its credibility, but operational and governance integrity remain concerns.

mitigationSunrun earns revenue primarily through long-term customer agreements (leases and PPAs) for residential solar and battery storage systems, collecting subscription fees over 20–25 year contracts, and secondarily through outright system sales; it also monetizes grid services by aggregating customer batteries into virtual power plants.
