Transportation accounts for about 18 percent of Boston's greenhouse gas emissions. Although not the largest source of emissions, it is often the most visible. Because we make transportation decisions every day, it is also an area where we can change faster. In the City of Boston, we are:

• Increasing the number of hybrid and alternative fuel vehicles in the City fleet and increasing the use of biofuels



• Expanding the CleanAir Cabs program , which provides incentives for hybrid and alternative-fuel vehicles in the City's taxi fleet



• Purchasing new school buses with better fuel mileage and lower emissions of air pollutants



• Providing Transportation and Air Quality grants to neighborhood groups working on local solutions



• Launching Boston Bikes, a citywide initiative to make Boston a better biking city with more bike racks and more convenient and safer routes



• Supporting transit-oriented development

City government uses vehicles to collect trash, remove snow, clean streets, and bring children to and from school, but the vehicles' engines emit gases that contribute to climate change and air pollution. That is why the City will now purchase hybrid or alternative-fuel vehicles wherever possible. Mayor Menino's executive order on climate action also requires that the City's current fleet of 450 diesel vehicles use a biodiesel blend to reduce greenhouse gas emissions. Reaching beyond its own fleet, the City of Boston's CleanAir Cabs program is providing financial incentives to encourage Boston taxicab owners to switch to hybrid or alternative-fuel vehicles and has created a distinctive CleanAir Cabs logo to mark these cars on the streets.
