Energy Efficiency & Renewable Energy

Buildings in Cambridge are responsible for more greenhouse gas emissions than transportation and waste combined, or over 80% of the city’s total emissions. Reducing building energy use is therefore a critical component of the City’s environmental and climate goals.

Through its Cambridge Energy Alliance program, the City helps residents and small businesses reduce energy consumption by implementing energy efficiency measures and investing in clean or renewable energy technologies. Large Businesses can learn about the City’s energy requirements for LEED, energy disclosure and net zero energy planning.
