To understand our impact on climate change and measure progress over time, Cambridge has committed to doing a greenhouse gas inventory of its emissions at least every five years. This information helps the City understand where emissions are coming from, identify the biggest opportunities to reduce them, and guide the policies and programs that support our goal of reaching net zero emissions by 2050.
