Buildings and energy industries in Cambridge consume more than half of all energy used in the community and contribute 82% of Cambridge's total GHG emissions, so we need a clear plan for reducing emissions from buildings. Our Net Zero Action Plan outlines polices and programs that influence the two biggest factors in a building's carbon footprint: how much energy that building uses, and where that energy comes from in the first place.Learn More

Greenhouse gas emissions (GHGs) are produced when we use energy in our homes and offices, dispose of waste or sewage, and use vehicles. GHGs trap heat in the atmosphere, leading to lasting disruptions in our climate, such as higher temperatures, sea level rise, and more frequent extreme weather events that can cause flooding. Cambridge, along with many other cities, organizations, and businesses, both nationally and internationally, has committed to significantly reduce GHG emissions by 2050 to avoid severe impacts from climate change.Learn More
Throughout our daily lives, we all take actions that produce GHGs. Here are some actions you can take to reduce your contribution to the community's emissions:
Energy is a critical resource that we rely on to go about our daily activities. Unfortunately, much of our energy use and energy supply is currently unsustainable and causes climate change and environmental degradation. Innovations that allow us to use energy more efficiently and switch to cleaner, renewable fuel sources that can be stored will drastically improve the sustainability of our energy systems.
This page addresses community energy use from our homes, offices, and travel. It also addresses municipal energy use, which includes City-owned facilities, schools, and streets, as well as activities like water and wastewater pumping and solid waste pick-up.Learn More
Programs are available for residents and businesses to install solar panels on their homes or offices. If installing solar panels is not an option, you can purchase 100% renewable energy through the Cambridge Community Electricity Program, or invest in community solar!
There are a lot of opportunities to reduce energy use in your own home, such as switching to LED lights, adding insulation, and buying a heat pump.
Cambridge residents commute by car 1/3 as much as the average American.Learn More
The things we throw out have a large impact on our health and the health of the environment. All of the items we put in our trash carts are either sent to a landfill or incinerated, and both processes can pollute our air and water. We can reduce this impact by reducing the total amount of waste we generate, and by making sure that the waste we do generate is separated so that some of the waste can be reused or recycled.Learn More
Composting and recycling help to minimize the amount of trash that goes to incinerator/landfill, reduce greenhouse gas emissions, and yield useful products.
