By , the total number of vehicles could be 2 billion. The transport sector burns most of the world's petroleum and is one of the largest sources of global greenhouse gas emissions. It's also heavy on air pollution. Electric vehicles can reduce GHG emissions by half in compared to fossil fuel driven cars, offsetting up to Megatons of CO2-equivalents. Electrified cars also significantly reduce air pollution. Electrified cars made up just 0.
It will depend on incentives for producers and consumers such as tax breaks for clean electricity, taxation of CO2-emissions, elimination of fossil fuel subsidies and so on. Some countries have made major progress on the use of electrified cars.
Cars are also one of the most recycled products in the world - about 85 percent of all the materials are reused. Other industries could learn much from this. Spread the message. Make a donation. Or update your wardrobe with clothes from our modest but growing selection of sustainably sourced and crafted clothes. And according to a study by researchers at the University of Toronto , published in , 25 percent of cars and trucks are causing about 90 percent of pollution from the vehicle fleet.
The United States was long considered the world's biggest polluter in terms of carbon dioxide and other greenhouses gases, but China has moved into the top spot, according to the Global Carbon Project The percentage of air pollution caused by cars is higher in urban areas and higher still near major highways.
Fortunately, better fuels and new technologies in cars help. The U. According to the EPA, today's cars are 98 to 99 percent cleaner for most tailpipe pollutants compared to the s. Hybrid cars, electric cars and alternative fuels will continue to help, but the sheer number of people — and cars — on the roads offsets these improvements.
People can help by driving less. Combine trips for efficiency. Walk, bike, carpool or use public transportation when you can. According to the U. Department of Energy , "[h]ighway vehicles release about 1. Each gallon of gasoline you burn creates 20 pounds 9 kilograms of GHG.
