Clean Cars Minnesota: A win for public health, innovation, and the environment

, Clean Vehicles Analyst

On Friday, a Minnesota administrative law judge ruled the state can proceed with finalizing new clean car standards that will give Minnesotans more control over air quality improvements and progress toward the state’s greenhouse gas reduction goals, as well as increase vehicle model choices for Minnesota car buyers and save drivers money at the pump.

What is Lightweighting and How Does it Improve Fuel Economy in Vehicles?

Jeremy Lipshaw, MSE in Mechanical Engineering, , UCS

As a young engineer who has recently entered the workforce, I can confidently say that the technology needed to meet the Obama-era clean car standards still exists, and, that they are plentiful and accessible to manufacturers. Read more >

Are Electric Vehicles Really Better for the Climate? Yes. Here’s Why

, Senior vehicles engineer

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.

New Data Show Electric Vehicles Continue to Get Cleaner

, Senior vehicles engineer

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.

Vehicle Fuel Economy Standards—Under Fire?

Dr. Kate Whitefoot, , UCS

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.
