The City of Cambridge has officially launched Sustainable Cambridge, a new initiative that encompasses all of Cambridge’s efforts to address climate change while keeping the community welcoming, neighborly, and beautiful.
“Sustainable Cambridge is an all-of-government effort to support a climate-ready, welcoming, inclusive, thriving community,” said Julie Wormser, Chief Climate Officer, City of Cambridge. “It involves the City’s work on everything from managing flooding and heat waves to housing, equity, public health, and overall community well-being.”
With the tag line “All of Us. All In.” Sustainable Cambridge reaffirms a citywide commitment to transitioning from fossil fuels to renewable energy and maintaining a thriving community in a climate-altered environment. “We are committed to ensuring that everyone -- regardless of race, gender, age, socioeconomic status -- is safe from extreme weather,” added Wormser, “And we want to help lower the bar for other communities to be able to do the same.”
As part of the launch, the City of Cambridge has gathered all its climate and sustainability work into a single public-facing website www.cambridgema.gov/sustainable including:
• How Cambridge will hit our goal of net zero carbon emissions by 2050;
• How Cambridge is preparing our people and places for extreme weather;
• What residents can do at home, from energy efficiency to keeping bees;
• What people can do around Cambridge, from finding a park to volunteering;
• How to find help in an emergency; and
• More information on our plans, data, and lots of interactive maps
Residents can also subscribe and learn more about events, news and other exciting Sustainable Cambridge information.
In support of Sustainable Cambridge and Earth Month, the City of Cambridge will host a series of events and feature a variety of activities throughout the rest of April.
