Boston has moved past awareness-building and broad planning on climate and resilience. Its 2030 Climate Action Plan, released Monday, focuses on implementation, execution and measurable progress. “We’re having to create a new model for what it looks like to be a city that is really clear on what it wants to do and is accomplishing what needs to be done on climate change,” Oliver Sellers-Garcia, Boston’s Green New Deal director and environment commissioner, told Smart Cities Dive. Driven by mitigation — rapidly reducing emissions from buildings, transportation and energy — and resilience strategies designed to protect people and infrastructure from the impacts of climate change, the plan released Monday is a road map to making Boston carbon neutral by 2050. It sets goals for optimizing coastline resilience, curbing the effects of extreme heat by expanding the city’s tree canopy, aiming to deliver healthier living and working environments, addressing historic inequities and reducing emissions while protecting the communities most exposed to climate risk. To do so, it includes targets around small building decarbonization, reductions in passenger travel and electrification of the city’s heavy-duty vehicles, collectively aimed at cutting emissions in half by 2030. Sellers-Garcia identified five principles Boston leaned on to create its plan. Frame climate action around quality of life and affordability Data and science — which Sellers-Garcia called the “north star” in a city that’s home to world-class research institutions — are the plan’s foundation, he said. But numbers alone can’t capture the affordability, health and environmental justice goals that drive it, he added. The plan emphasizes healthier buildings, sustainable transportation, clean energy, waste reduction, green space and workforce development — issues that touch Bostonians every day — showing that climate policy can advance multiple goals at once. “We have [done] so much work in analysis on this plan,”
