To get to zero by 2050, Connecticut must cut climate pollution by 1.5 million metric tons of C02 equivalent a year.

Emissions in Connecticut

Million metric tons of carbon dioxide equivalent (MMTCO2e) emissions

We can do it. Here's how.

    🏠 Buildings

    28% of emissions in Connecticut comes from buildings.

    Mostly from different types of heating.

    Gas furnace, gas water heater, gas stove

    80% of the pollution of your typical home comes from heating your space, water, and food.

    To stop this pollution, we need to replace our furnaces with electric heat pumps, electrify our water heaters, and cook with induction and electricity instead of gas.

    Electric heat pump, electric water heater, induction stove

    There are 1.2 million buildings in Connecticut and 27% of building systems are already electrified.

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

    🚗 Getting Around

    38% of emissions in Connecticut comes from cars, trucks, and planes.

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

    Mostly from our cars.

    To cut this pollution, if you have a car, your next one needs to be an electric vehicle (EV).

    Or try going car-free with public transit, bikes/e-bikes, or walking if it works for you.

    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 emissions in Connecticut comes from making power.

    Specifically from coal, gas, and oil plants.

    To cut this pollution, we need to replace all dirty power plants with clean ones (mostly wind and solar).

    But wait! Remember how we electrified all cars and buildings?

    Our machines don't pollute now, because they run on electricity!

    But that means we need to make more power for those new electric machines - twice as much power as we make now!

    And all of it needs to be clean power!

    So to cut the climate pollution from our power, cars, and buildings we need to INSTALL 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.

    🏭 Other Emissions

    The last 15% of emissions in Connecticut comes other sources

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

    This includes industry, landfills, and farming.

    There's no one solution to solve these problems, but there are a lot of great ideas!

    These include:

    • Regenerative agriculture to sequester carbon in soil
    • Composting to reduce landfill methane emissions
    • New techniques for manufacturing CO2 emitting materials, like concrete
