Transportation on Climate!

Did you know that the transportation sector generated 27% of all GHG emissions in 2020, primarily from burning fossil fuels to power for trucks, cars, ships, trains, and planes? Learn more about the our cars' emissions and the sector's progress in transitioning to cleaner energy.

Car Fuel Types

Gas Vehicle Components

Gasoline Vehicles

Gasoline vehicles use a internal combustion engine. When the fuel and air combine in the combustion chamber, they ignite a spark from the spark plug and convert the gasoline into motion so that the car can move.

  • 8,887 grams of tailpipe CO2 created/gallon of gasoline
  • emits methane and nitrous oxide (higher global warming potential gases) from the tailpipe
  • lower cost of taxes compared to electric vehicles on average
Electric Vehicle Components

Fully Electric Vehicles

Fully electric vehicles uses a traction battery to power the electric motor and must be plugged in to a wall outlet or charging equipment.

  • emits no exhaust from the tailpipe
  • over 47,000 stations available nationally as of April 29, 2022
  • emissions are created during the production and distribution of the electricity
Hybrid Electric Vehicle Components

Hybrid Electric Vehicles

Hybrid electric vehicles have an internal combustion engine and an electric motor that uses energy stored in batteries. Instead of charging by plugging into sources of electricity, the batteries are recharged through regenerative braking.

  • produces lower emissions compared to gas-only vehicles >
  • suited for city driving and not for speed and acceleration >
  • energy released during braking is captured to recharge the battery

Even though EVs have no tailpipe emissions, emissions are created during the production and distribution of the electricity used to fuel the vehicle.

Regardless, there are good news: In 2021, 20% of electricity produced was made from renewable sources, signaling a positive shift.
