Hawaii
Back to mapTo get to zero by 2050, Hawaii must cut climate pollution by
0.8 million metric tons of CO2 equivalent a year.
Emissions in Hawaii
Million metric tons of carbon dioxide equivalent (MMTCO2e) emissions
This is how we're going to do it.
- Boilers and furnaces with heat pumps
- Gas stoves with induction ranges
- 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
3% of Hawaii'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 Hawaii's 253,000 buildings.
That means we only need to electrify the remaining 253,000 buildings in Hawaii. That's around 9,000 per year.
That cuts 3% of the pollution.
Decarbonize Our Transport
51% of Hawaii'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 484,000 cars and trucks in Hawaii!
There are 484,000 vehicles in Hawaii and 11,000 are already electric (2.2% of the total).
We need to electrify the remaining 473,000 vehicles. That's around 17,000 a year.
That cuts 51% of the pollution.
Decarbonize Our Power
28% of Hawaii's pollution comes from burning coal, gas, and oil to make power.
To cut this pollution...
Put solar panels on your roof!
Then, we'll replace all fossil fuel power plants with solar and wind farms.
...and find good jobs for those workers.
Current Fossil Fuel Power Plants in Hawaii
1 coal plant
AES Hawaii
Honolulu County
203 MW
18 oil plants
Kahe
Honolulu County
610 MW
Waiau
Honolulu County
475 MW
Kalaeloa Cogen Plant
Honolulu County
299 MW
Maalaea
Maui County
230 MW
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 324 MWs of wind and 445 MWs of solar.
Since Hawaii already has 205 megawatts of solar power generation and 77 megawatts of wind power generation, that's 9 Megawatts of wind capacity AND 9 Megawatts of solar capacity a year we need to build.
That cuts 28% of the pollution.
And gives us zero-emissions power we need to eliminate pollution from buildings and cars!
Other Emissions
The last 19% of Hawaii'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:
