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.

Finally, the plane is the most polluting means of transport and the one that generates the most greenhouse emissions.
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.
We find that car and motorcycle use for shopping and leisure activities fell more sharply along lines with a larger increase in regional passenger trains. These results indicate that expansions of local passenger railways reduce air pollution due to substitution from cars and motorcycles to trains.

These massive, track-mounted vehicles, which use a diesel generator to power electric motors and move rail cars carrying cargo or passengers, are major polluters, responsible for a growing share of the emissions that increase cancer risk, shorten lives and worsen smog across California.
In fact, unless you're looking to venture from Los Altos to LA off-road through state parks the whole way—in a Hummer with Tonka-truck mud tires—driving is generally greener than flying.
Thunberg refuses to fly because of the carbon emissions of the airline industry and the trip was announced as carbon neutral. As a racing sailboat, the Malizia II has no toilet, fixed shower, cooking facilities or proper beds.
Trains are generally thought to be a green alternative to fossil fuel-heavy modes of transportation, such as cars and airplanes, but many types still burn diesel fuel. And those emissions can build up, particularly in enclosed areas. (Watch how people are trying to break their fossil fuel habit.)
Besides walking and biking, traveling by train remains one of the greenest and most environment-friendly options when getting around. Regardless if electric or diesel-powered, trains emit between 66 and 75 percent fewer carbon emissions when compared to cars and airplanes.
As a result, rail transport has many advantages such as high carrying capacity, economy, reliability, environmental impact, safety and independence from traffic congestion. It is a preferred method of transport, especially when large volumes and long-distance cargoes are to be transported.
Top polluting sector: fossil fuelsIt is no surprise that the fossil fuels sector is the most polluting in the world. Despite this knowledge, emissions from fossil fuels keep increasing. After a brief decline during the Covid 19 pandemic, they grew by 1% in 2022, reaching 40.5 gigatons of CO2.
