Transportation is the second largest source of emissions in Cambridge. 

While Cambridge already has high levels of public transit and active transportation (walking and biking), reducing emissions will require switching trips made by vehicle to trips made by public transit, bicycling, walking or carpooling. Vehicles trip that remain will need to be made by vehicles that have switched from gasoline and diesel, to electric.

Estimates show that the emissions reductions attributed to the following strategies will not get us to carbon neutrality by 2050. However, we will continually re-evaluate these strategies to find new opportunities to further reduce miles driven, increase use of public and active transportation, and further electrify transportation. In addition to this, the portion of our electricity supply that is generated by renewable, low or zero carbon sources will need to continually increase. 

There may be some emissions that simply cannot be eliminated.  For any residual emissions, the City will explore how it can offset these emissions by investing in a project that reduces a source of emissions outside of the Communities emissions.

Active Transportation and Public Transit

Continuing to build a transportation system that provides every member of the community safe, reliable, affordable and flexible access to transportation modes other that driving in a personal vehicle provides the greatest benefit, not just for emissions reductions, but for health, well-being and equity.

Low and Zero Carbon Mobility Solutions

Motorized vehicles will need to switch from gasoline and diesel to electric. Switching to electricity alone will reduce emissions, but as with buildings, further emissions reductions will be achieved if the electricity supply is generated by an increasing portion of low or zero carbon renewable energy.
