It concludes that these approaches often fail to achieve targeted emissions reductions when full life cycle impacts—such as upstream methane leakage, energy penalties, and production emissions—are considered. Furthermore, the brief argues that these technologies perpetuate environmental and social inequities by maintaining the operation of gas plants. In contrast, the report finds that transitioning to renewable energy sources like wind and solar provides superior reductions in carbon, air, and water pollution while offering lower costs and fewer land-use impacts.","ai_generated":true,"unit":"ucs-000292#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Hydrogen cofiring can lead to an overall increase in climate pollution compared to burning gas alone, depending on the production method.
