Reducing Transportation Emissions

Reader Contribution by Ruth Barton

According to statistics, the US release the second highest amount of carbon emissions in the world, after China. A staggering 33% of the US carbon emissions that are released comes from transportation, with 60% of the transportation emissions coming from gasoline for cars and light trucks. This means that transportation is the second largest contributor of U.S greenhouse gas emissions after the electricity sector.

Since 1990 greenhouse gas emissions from transportation have increased by roughly 18%, which is largely due to an increasing demand for travel. Furthermore, the number of vehicles travelled by car and light trucks has increased by 35% from 1990 to 2012. Again, this is for a number of different reasons ranging from population growth, economic growth, urban sprawl and low fuel prices early on in this period.

Although efforts have already been increased to reduce the amount of carbon emissions created by transport, such as the EPA and the National Highway Traffic Safety Administration (NHTSA) taking coordinated steps to enable the production of a new generation of clean vehicles, through reduced greenhouse gas (GHG) emissions and improved fuel use from on-road vehicles and engines, from the smallest cars to the largest trucks, there is still a lot more that needs to be done if the US are ever going to achieve their goal of reducing carbon emission by 30% from 2005 levels, as announced by President Obama.

How to Reduce Transportation Emissions

Efforts should be increased to encourage more U.S. citizens to change their travel habits and make more eco-friendly choices. Whether it is public transport, car sharing or walking/running/biking whenever or wherever possible. It would be beneficial to introduce more incentives for Americans to actually travel in a more environmentally friendly way, such as the bike to work scheme that is being used in the UK. If UK businesses opt into the bike to work scheme, both employers and employees can benefit, including getting a bike for a discounted price, saving money on traveling costs, get more fit and healthy as well as significantly reducing their carbon footprint. If more American businesses had a scheme similar to this, it would all contribute to making the U.S a greener country. 

Although it would be great if everyone could run, walk, bike everywhere and get public transport at any point of the day, in reality this is not at all possible for every U.S citizen. However, that doesn’t mean to say that people can’t travel in a more green way.  60 percent of transportation emissions come from gasoline for cars and light trucks, but this figure could significantly be reduced if more U.S citizens opted for ‘green’ cars. For example, a gasoline-powered car that gets 20mpg releases 20lbs of CO2 in comparison to a plug-in hybrid car that gets 100mpg releases just 4 lbs of CO2.

Buying a Green Car

One issue that might be raised from this point is the expense of buying a newer ‘greener’ car, which many U.S. citizens may not be able to afford. However, it could be argued that many green cars have been made to be affordable to a large target market. Alternatively, there is the option of car financing which again is something that many UK citizens have chosen to do in order to get the car they like as well as obtain a greener lifestyle. For example, Simon Gray at Credo Asset Finance, who offer car finance in Norwich, is delighted to see so many people seeing the benefits of car finance:

“We are delighted at the increasing interest in people coming to us for the best car finance deals around so that they can get the car they want at an affordable price for them. As ‘being green’ has become an increasing important issue for many consumers’ lifestyles, we have seen a growing interest in people opting for cars that are better for the environment.”

So, although strategies are already being put in place to reduce the amount of carbon emissions released by transport, perhaps America should introduce some more strategies to reduce transportation emissions even further in the U.S.
