Boston's mayor has a plan to accelerate the city's goal of reducing carbon emissions.

Democratic Mayor Marty Walsh says the updated Climate Action Plan he's releasing Tuesday will significantly cut carbon emissions from buildings, which account for most emissions in the city.

Among the initiatives are investing in energy saving improvements to city-owned buildings, transitioning the city's vehicle fleet to low-emission vehicles and developing new guidelines for city-backed affordable housing projects.

The mayor hopes the plan puts Boston on the path of becoming "carbon neutral" by 2050.

He also says the plan puts the city on track to meet goals laid out in the Paris Climate Agreement, which the U.S. withdrew from in 2017.

Walsh is among the mayors gathering in Copenhagen, Denmark starting Wednesday for an international climate summit.
