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

    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 dirty 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!

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

    We need to electrify (or replace) the remaining 1.2 million gas-powered 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 two times the electricity we have today.

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

    Since Connecticut already has 1 Megawatts of wind and 131 Megawatts of solar, that's 3,000 Megawatts of wind power we need to build and 3,000 Megawatts of solar power. That's around 134 Megawatts of wind power and 124 Megawatts of solar power a year.

    Decarbonizing all dirty power 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
