How can we make transportation more environmentally friendly?

Sustainable transportation options run on clean fuel, batteries, or both. Alternative fuels can be used in flexible-fuel and dual-fuel vehicles as well as vehicles with advanced technology, such as hybrid power systems and fuel cells. Alternative fuels help conserve fuel and reduce emissions.



Making transportation more environmentally friendly in 2026 involves a multi-faceted approach focusing on electrification, shared mobility, and urban redesign. On an individual level, shifting from private internal combustion vehicles to electric vehicles (EVs) powered by renewable energy grids is the most direct impact. However, systemic changes are more powerful: cities are increasingly adopting "15-minute city" designs that prioritize walking and cycling infrastructure, significantly reducing the need for motorized transit. In the public sector, the expansion of high-speed rail—like the continued growth of Brightline in the U.S. or the Eurostar network—provides a low-carbon alternative to short-haul flights. Additionally, the maritime and aviation industries are testing sustainable fuels (SAF) and hydrogen fuel cells to tackle long-distance emissions. In 2026, "Mobility as a Service" (MaaS) apps are also helping by integrating buses, trains, and bike-sharing into a single digital platform, making it easier for citizens to choose the most eco-friendly route for every journey.

Public transportation gets people where they're going while emitting far fewer climate-warming greenhouse gases than private cars. The reason is simple efficiency: while cars usually carry just one or two people at a time, a bus can carry 50 or more, and a train in a large city may carry thousands.

The benefits of sustainable transportation in the United States include: Cost savings on fuel and vehicles. Reduced carbon emissions from burning fossil fuels, resulting in less air pollution. Job creation with increased vehicle and battery manufacturing and fuel production.

MORE DETAILS

Through the emissions from combustion of fossil-derived fuels, transportation systems contribute to degraded air quality, as well as a changing climate. Transportation also leads to noise pollution, water pollution, and affects ecosystems through multiple direct and indirect interactions.

One of the biggest environmental benefits of trains is that they consume far less energy than other types of transport. It takes a huge amount of fuel to get a plane carrying hundreds of people airborne, whereas trains are streamlined, require much less energy to move, and are increasingly able to run on electricity.

MORE DETAILS

Car emissions are a major source of pollution. Cars and trucks emit twenty percent of all greenhouse gases emitted in the United States[1], which is the second largest greenhouse gas emitter in the world.

When transport systems are efficient, they provide economic and social opportunities and benefits that result in positive multiplier effects, such as better accessibility to markets, employment, and additional investments.

Walk, bike or take the train for the lowest footprint Over short to medium distances, walking or cycling are nearly always the lowest carbon way to travel.

MORE DETAILS

As you add more passengers, the amount of emissions your party produces increases on a flight. In contrast, the amount of greenhouse gas emissions, which trap heat and lead to global warming, produced decreases per person when driving.

MORE DETAILS

If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.
