- Meeting growing customer demand for RNG.
- Competition from other alternative fuels (electric vehicles, hydrogen, renewable diesel).
- Potential diversion of RNG from transportation fuel due to utility procurement goals.
- Regulatory and market changes affecting the RNG marketplace.
- Climate change impacts on dairy farms (droughts, floods) affecting RNG supply.
- Rapidly evolving ESG reporting landscape.
Clean Energy Fuels Corp.
Greenhouse gas emissions & sustainability report data
In its 2021 reporting, Clean Energy Fuels Corp. disclosed greenhouse gas emissions of 1.8M tCO2e/year. By scope: Scope 1: 57.8K tCO2e/year; Scope 2: 54.5K tCO2e/year; Scope 3: 1.7M tCO2e/year. Figures are as stated in the company's own report and may use different boundaries, units or methods (for example market-based vs location-based Scope 2), so compare with care.
