What is decarbonization?
Decarbonization is the process of reducing the amount of carbon dioxide (CO2) released into the atmosphere as a component of greenhouse gas (GHG) emissions. Decarbonization efforts focus on replacing fossil fuels with low-carbon or zero-carbon energy sources for the transportation, electricity generation, industry, agriculture, commercial (buildings and cooling/heating), and residential sectors.
Why is decarbonization critical?
Decarbonization reduces the impact of human activity on the climate, mitigating the effects of global warming. The 2015 Paris Agreement set a goal of limiting global warming to well below 2℃ (preferably to 1.5℃) compared to pre-industrial levels by 2050. Achieving this will require government policy, widespread public support, and technology innovation to lower the cost of carbon-free energy and accelerate decarbonization to meet climate goals.
Why should we decarbonize the transportation sector?
Transportation is one of the largest global contributors of CO2 emissions. Meeting climate targets will require reducing emissions by about 45% by 2030, and reaching net zero by mid-century. As transportation demand continues to grow globally, decarbonization efforts will need to offset rising emissions. Decarbonization should also address reducing CO2 emissions in the manufacture, transport, and disposal of road vehicles and their components.
What is the role of electric vehicles in decarbonizing transportation?
Replacing internal combustion engine (ICE) vehicles with battery electric vehicles (BEVs) is the only way to substantially reduce CO2 emissions in the transportation sector. Battery electric vehicles generate about 73% less lifecycle greenhouse gas emissions than comparable gasoline vehicles, with even greater reduction potential as grids incorporate more renewable energy.
- ICE vehicles fueled by a fossil/bio-fuel mix emit 235g CO2/km
- BEVs fueled on today’s average grid electricity are 63g CO2/km
- BEVs fueled by a fully renewable grid go down to 52g CO2/km
What types of vehicles does the transportation sector include?
Electrification of light-duty road vehicles, medium- or heavy-duty trucks, and other means of transportation will help decarbonize the sector.
| Transportation segment | Examples | Electrification potential | Decarbonization approach |
| Light-duty vehicles | Passenger cars, SUVs, small trucks | High | Battery electric vehicles and smart charging |
| Buses | Municipal and school buses | High | Fleet electrification and managed charging |
| Commercial and freight vehicles | Delivery vans and medium- and heavy-duty trucks | Growing | EV charging infrastructure and alternative fuels |
| Aviation | Aircraft | Limited today | Low-carbon fuels |
| Maritime | Ships | Limited today | Low-carbon fuels |
| Rail | Passenger and freight rail | Moderate | Electrification and low-/zero-carbon fuels |
What is driving EV adoption?
Global electric car sales exceeded 20 million in 2025, representing about 25% of all cars sold. Factors contributing to more electric vehicle purchases include:
- wider availability of EV models
- EV pricing on par with ICE vehicles
- EV charging infrastructure development
- availability of reliable charging for EV drivers
How can we accelerate transport decarbonization?
Renewable energy
Globally, renewable energy generation overtook coal for the first time. Powering electric transportation with more renewable energy sources, such as solar, wind, and hydropower, can further reduce GHG emissions. Electric vehicles can also help directly decarbonize the grid by using vehicle-to-grid (V2G) technology to serve as “batteries on wheels.” Additionally, smart energy management enables EVs to charge when electricity demand is low and transfer electricity back when demand is high to help balance the grid.
Fleet electrification
As fleets scale and support more services, their reliance on ICE vehicles contributes significantly to greenhouse gas emissions, making electrification an important step toward reducing them. Benefits of electrification for fleets include:
- lower total cost of ownership
- meeting government and corporate carbon-reduction targets
- Improving brand perception and customer loyalty
Also, fleets that use smart EV charging can charge more vehicles within fixed depot capacity, reducing peak demand and energy costs, improving resiliency, and supporting electrification without immediate infrastructure upgrades.
Decarbonization progress
While global decarbonization efforts must intensify to meet Paris Agreement targets, progress is underway across several sectors. Zero-carbon solutions are already competitive in industries that account for about 25% of global emissions, particularly in the power and transportation sectors. By 2030, zero-carbon technologies could become competitive across sectors that account for more than 70% of global emissions, helping to drive continued investment and innovation in clean energy and electrification.
