Buildings contribute to over half of greenhouse gas emissions in the City of Boston.

Addressing buildings' energy efficiency is the first step to combatting climate change. Councilor Matt O'Malley has led on a Net Zero Carbon initiative, and has brought elected officials, advocates, academic experts, developers, lawyers, and architects to the table to achieve a robust plan.

As the chairman of the environmental & sustainability committee...

Councilor Matt O'Malley understands the importance of recycling, along with the harmful effects that single-use plastic bags have on the City's trees, streets and gutters. Plastic bags continue to pollute our water and our land, and contribute to global climate change. Councilor O'Malley has passed an ordinance for Boston to ban single-use plastic bags.
