To get to zero by 2050, Connecticut must cut climate pollution by
1.5 million metric tons of CO2 equivalent a year.

Million metric tons of carbon dioxide equivalent (MMTCO2e) emissions

This is how we're going to do it.

    28% of Connecticut's climate pollution comes from buildings.

    We burn fossil fuels to heat our air, water, and food.

    To cut this pollution...

    Let's electrify our heat!

    We'll replace...

    ...in all of Connecticut's 1.2 million buildings.

    In fact, 27% of buildings in Connecticut are already fossil fuel free!

    That means we only need to electrify the remaining 882,000 buildings in Connecticut. That's around 32,000 per year.

    Decarbonize Our Transport

    🏭 Other: 15%🔌 Power: 19%🚗 Transport: 38%🏠 Buildings: 28%

    38% of Connecticut's pollution comes from cars, trucks, trains, and planes.

    But mostly from cars.

    To cut this pollution,

    your next car must be electric.

    Or consider going car-free with public transit, bikes/e-bikes, car share, or other alternatives!

    Then, we'll electrify all 1.2 million cars and trucks in Connecticut!

    There are 1.2 million vehicles in Connecticut and 9,000 are already electric (0.7% of the total).

    We need to electrify the remaining 1.2 million vehicles. That's around 43,000 a year.

    19% of Connecticut's pollution comes from burning coal, gas, and oil to make power.

    Dirty power plant

    To cut this pollution...

    Put solar panels on your roof!

    Then, we'll replace all fossil fuel power plants with solar and wind farms.

    We need to replace dirty power plants with clean ones (mostly wind and solar)

    ...and find good jobs for those workers.

    But wait!

    It's not enough to replace our power plants with wind and solar farms.

    To power our electric cars and buildings, we need 2x the electricity we have today!

    In all, we'll need to build 4,000 MWs of wind and 4,000 MWs of solar.

    Since Connecticut already has 131 megawatts of solar power generation and 1 megawatts of wind power generation, that's 134 Megawatts of wind capacity AND 124 Megawatts of solar capacity a year we need to build.

    That cuts 19% of the pollution.

    And gives us zero-emissions power we need to eliminate pollution from buildings and cars!

    The last 15% of Connecticut's climate pollution comes from other sources...

    This includes farming, landfills, industry, and leaks from gas pipelines.

    There's no one solution to solve these problems, but there are lots of great ideas:

    • No-till farming to keep CO2 in the soil
    • Capturing methane leaks from landfills
    • Capturing CO2 to make emissions-free concrete
    • Burning green hydrogen to make emissions-free steel
    • Plugging methane leaks from gas pipelines
