One of the questions I’m most frequently asked about electric vehicles (EV) is: “Are they really a cleaner option?” While it’s obvious that a fully-electric vehicle eliminates tailpipe emissions, people often wonder about the global warming emissions from generating the electricity to charge an EV. The latest data affirms that driving on electricity produces significantly fewer emissions than using gasoline and is getting better over time.

UPDATE, 2/26/20: Read the latest installment of this blog, “Are Electric Vehicles Really Better for the Climate? Yes. Here’s Why,” which includes electricity power plant emissions data for 2018 and its impact on electric vehicles.
New data from the US EPA on power plant greenhouse gas emissions are in, and electric vehicles (EV) in the US are even cleaner than they were before. The climate change emissions created by driving on electricity depend on where you live, but on average, an EV driving on electricity in the U.S. today is equivalent to a conventional gasoline car that gets 80 MPG, up from 73 MPG in our 2017 update.

Last year, transportation became the sector with the largest CO2 emissions in the United States. While the electricity industry has experienced a decline in CO2 emissions since 2008 because of a shift from coal to natural gas and renewables, an equivalent turnaround has not yet occurred in transportation. Reducing emissions in this sector is critical to avoiding the effects of extreme climate change, and the Corporate Average Fuel Economy (CAFE) and Greenhouse Gas (GHG) emissions standards are an important mechanism to do so.

A new study by consulting firm Arthur D. Little (ADL) claims that the benefits of electric cars, both environmental and economic, are lower than others, including UCS, have shown. However, the differences are largely due to questionable assumptions about battery replacements and the use of electric vehicles as a gasoline car replacement. Read more >

In Brazil, deforestation in the Amazon has been compared to a starved dragon. However, this dragon has been under control in the past. Deforestation in the region declined 70% from 2005 (19,014 km2) to 2014 (5,012 km2) in response to different strategies described in the literature. But the monster was not killed, it was just taking a nap. Read more >
