To get to zero by 2050, Connecticut must cut emissions by 4.2% a year

This is how we're going to do it
- Boilers and furnaces with heat pumps
- Gas stoves with electric induction stoves
- 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
Decarbonize Our Buildings
26% 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 buildings.
Heating burns the most fuel in our homes, so let's start there. Of Connecticut's 1.5 million homes, 20.7% already heat without burning any fuel, mostly with electricity!
That means we need to electrify the heating in the remaining 1.2 million homes in Connecticut. That's around 49,000 per year.

Decarbonize Our Transport
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 3.0 million vehicles in Connecticut and 49,000 are already electric (1.6% of the total).
We need to electrify (or replace) the remaining 2.9 million gas-powered vehicles. That's around 122,000 a year.

Electrifying all transportation cuts 38% of the pollution.
Decarbonize Our Power
24% of Connecticut's pollution comes from burning coal, gas, and oil to make power.
That's because of how power is generated in Connecticut today.

But there's already 45% carbon-free electricity generation in Connecticut!
To clean up the emissions from the polluting power plants we need to replace all fossil fuel power plants with solar and wind farms.
...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 11,000 megawatt (MW) of wind power and 15,000 MW of solar power.
Since the average wind turbine provides 2.75 MW of peak capacity, Connecticut would need to install about 4,000 turbines.
Since Connecticut already has 4 MW of wind and 1,000 MW of solar, that's 11,000 MW of wind power we need to build and 14,000 MW of solar power. That's around 463 MW of wind power and 576 MW of solar power a year.

Decarbonizing all dirty power cuts 24% of the pollution.
And gives us zero-emissions power we need to eliminate pollution from buildings and cars!
Other Emissions
The last 12% 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:
That doesn't mean there's no solution, it just means that clean electrification doesn't help with these problems, and you could fill a whole book with covering all of them. We need to encourage our politicians to invest in researching new solutions and implementing existing solutions to these problems!
