The first step is to calculate your carbon footprint. What Is Greener? But you could drive 336 cars to Edinburgh for the same CO 2 as one plane. According to recently published figures from the FAA, in 2012 the energy intensity gap was 3,193 BTU/passenger mile for driving, compared to 2,654 BTU/passenger mile for flying. But these alone wont get you to become a net-zero traveler. EarthTalk is a regular feature of E/The Environmental Magazine. There are myriad useful Web-based carbon calculators that can help you make most run-of-the-mill consumer decisions: CoolCalifornia; Nature Conservancy; ICAO, to name a few. Like cars, planes emit carbon dioxide and other greenhouse gases when they burn fuel. As a solo rider, driving a car wouldnt help lower your emissions it would be higher than air travel, at 120 pounds of CO2. The result is that associated energy intensity and greenhouse gas emissions are very high, making air travel look like a comparatively sound alternative. So you donate your cash to the emissions-reducing project, and the amount of carbon your donation helps the company stop producing or sequester meaning absorb from the atmosphere, like many plants do offsets the carbon emissions from your trip. Indeed, a 2010 study from researchersat the University of Oslos International Institute for Applied Systems Analysis found that short-lived climate factors make a decisive difference in terms of mode comparisons: Air travel results in a lower temperature change per passenger-kilometer than car travel on the long run; the integrated radiative forcing of air travel is on short- to medium time horizons much higher than for car travel. Subscribe to our weekly newsletter. 54-58., doi:10.1038/nclimate1068. Second, beyond carbon dioxide, emissions by airplanes have some particularly problematic aspects. EVs contain lithium-ion batteries, traction motors, and electronic controllers whose production createsup to 60% more carbon dioxide emissionsthan the production of ICEVs, according to a 2017 study comparing the life cycle of conventional and electric vehicles in China. First, in terms of pounds of carbon dioxide produced per gallon of fuel, there is not a huge difference between a gallon of gas for a car and a gallon of either jet fuel or aviation gas: Jet fuel produces an average of 21.1 pounds of CO2 per gallon and aviation gas 18.4, while fuel for cars is 19.6, according to the U.S. Energy Information Administration. In his book How bad are bananas: the carbon footprint of everything, Mike Berners-Lee estimates the footprint based on specific food types. Greenhouse gases are measured in carbon dioxide equivalents (CO2eq), meaning they also account for non-CO2 greenhouse gases and the increased warming effects of aviation emissions at high altitudes.2.
