What you drive, how you drive, and what fuel you use can impact both the environment and your pocketbook.

Purchasing the most environmentally friendly vehicle has never been easier. To save fuel, money and the environment, just look for the SmartWay mark.

Since conventional vehicles still make up the majority of new vehicles purchased, and will continue to do so in the years to come, it may be good for you, your wallet, and the environment to learn about some of these newer options now available on the dealership lot.

EVs and PHEVs are now available in multiple vehicle classes. There are currently about 40 EV and PHEV models on the market, and more models are expected to be released in the coming years.

Charging your all-electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV)–together known as plug-in electric vehicles (PEVs)–is similar to charging your other electronics.

Hydrogen Fuel Cell Vehicles (FCVs) are similar to electric vehicles (EVs) in that they use an electric motor instead of an internal combustion engine to power the wheels. However, while EVs run on batteries that must be plugged in to recharge, FCVs generate their electricity onboard. 

Together, we can make a difference by encouraging cleaner, more efficient transportation

See answers to common questions about greenhouse gas emissions from passenger vehicles.

EPA and the National Highway Traffic Safety Administration (NHTSA) have developed regulations to reduce greenhouse gas (GHG) emissions and improve the fuel economy of passenger cars and trucks.

The transportation sector is one of the largest contributors to anthropogenic U.S. greenhouse gas (GHG) emissions.

This annual report is part of EPA’s commitment to provide the public with information about new light-duty vehicle greenhouse gas (GHG) emissions, fuel economy, technology data, and auto manufacturers’ performance in meeting the agency’s GHG emissions standards.

Cars, SUVs, and light duty trucks that are fueled by gasoline, diesel, and E85 emit both greenhouse gases and smog-forming pollutants from their tailpipes.

Driving your vehicle releases greenhouse gases into the atmosphere and contributes to climate change—but you can take simple, easy steps to cut your emissions, reduce our nation’s dependence on oil, and save money.

It costs money to get around.

EPA’s successful car and truck standards will lead to significant greenhouse gas (GHG) emissions reductions.

What do you think transportation will be like in the future?

EPA’s National Vehicle and Fuel Emissions Laboratory (NVFEL) tests new cars and trucks sold in the U.S. to ensure that they comply with federal emissions and fuel economy standards.

Buying a high MPG vehicle saves you money at the pump.

Buying a vehicle? Want to compare fuel economy?

Self-driving vehicles (a.k.a. automated vehicles) have captured the public’s imagination for decades.
