In the past six months, the price of gasoline in the United States has declined precipitously - from its June peak of $3.63 per gallon to less than $2 in some parts of the country now.
The effect this sharp price decline will ultimately have on greenhouse gas emissions is not yet known, but a reasonable estimate is that emissions will rise as less efficient cars and trucks become popular for the first time in years. Luckily for the climate, stronger federal fuel economy standards will mean that emissions from the transportation sector won’t rise nearly as much as they would have.
Using travel data from the U.S. Energy Information Administration (EIA), monthly vehicle sales data, and fuel economy calculations by Michael Sivak and Brandon Schoetle of the University of Michigan, we calculate that vehicles purchased in last five months will emit 7.8 million more metric tons of greenhouse gases than if car-buying habits before the gas price drop had continued. An average car emits about 43 metric tons of greenhouse gases over its useful life, so the additional emissions are about the same as putting 180,000 new cars and light trucks on the road.
The sudden plunge in gas prices can make it tempting to forget the lessons of the past.
Sales of electric vehicles (EVs) were up 25 percent last year, and automakers are looking to boost sales further in 2015 with new and updated models. Clearly, EVs have moved beyond their infancy. But continued growth in the EV market will require smart public and private strategies to expand charging infrastructure so motorists don’t have to worry about running out of juice.
Advancing the deployment of low-carbon vehicle technology, like EVs, is essential if we’re going to achieve meaningful emissions reductions from the transportation sector, which is responsible for 28 percent of U.S. greenhouse gases. Globally, the problem is more acute as the number of light-duty vehicles on the road is expected to double to more than 2 billion by 2050.
Automakers will begin introducing their second generation EVs beginning this month with the 2016 Chevy Volt. While sales will likely jump because of the incremental improvements from the first generation Volt, more time is likely needed for batteries to improve and charging infrastructure to be deployed.
Our work for the Washington State Legislature shows that new business models to foster private investment in charging infrastructure will be vital, but public sector policies and incentives will still be needed in the near term to keep the market growing.
Progress on a multifaceted global challenge like climate change doesn’t happen in one flash of bright light. This can lead to the impression that little is being accomplished, especially when stories highlight areas of disagreement.
Nothing can be further from the truth. In reality, progress is more like the brightening sky before dawn. We saw positive steps in 2014, and they’ll help lay the groundwork for significant climate action in 2015 in the United States and around the world.
In the U.S., we will see the EPA Clean Power Plan finalized and states taking up the challenge to develop innovative policies to reduce harmful carbon dioxide emissions from power plants. Allowing governors to do what they do best, innovating at the state level, will be a key achievement of 2015.
Internationally, more countries than ever before will be putting forward new targets for reducing greenhouse gas emissions ahead of talks in December in Paris to hammer out a climate pact to replace the Kyoto Protocol.
In the New Year, we will be building on solid progress made in 2014 by governments, businesses, and individuals. Here are 10 examples:
My ride for the weekend: BMW’s first mass-produced all-electric vehicle.
Washington, D.C., is well-situated for day trips with mountains, forests, beach and bay all a short drive away. On a recent weekend, I was lucky enough to tool around in style. BMW lent me their new electric car – the i3 – and asked that I race it around the DC metro region. (Or perhaps that’s just how I heard them.)
The car handles beautifully the way you’d expect a BMW to, and proves there’s no performance tradeoff by going with an electric vehicle (EV). For most drivers, EVs like the i3 can accommodate daily driving needs. The average American only travels 30 miles per day. In particular, EVs are well suited for commuting because a driver can charge at home or the workplace. But day-tripping with an EV can take more planning and I learned firsthand that a robust public charging network is essential if EVs are to make more headway in the marketplace.
At C2ES, we often cite the importance of public charging stations to extend the range of EVs and give drivers confidence that an EV is a practical replacement for their conventional car. To allow EV drivers to travel as they would with a gasoline car, quick charging stations are needed along major roadways. Multiple, slower charging stations (referred to as Level 2) should be at key destinations to provide redundancy in case stations are in use or down for maintenance. Those are some of the conclusions of our new paper assessing the public charging infrastructure in Washington state and the same can be said of Washington, D.C.
Sales of electric vehicles (EVs) in the United States nearly doubled last year—and with consumer acceptance broadening, sticker prices dropping, new models on the way, and policy support growing, the outlook is even better for 2014.
In 2013, EVs increased their market share by 70 percent from 2012 levels, while all-vehicle sales grew 8 percent to reach a six-year high. Still, EV sales continue to lag forecasts made when these cars hit the market in late 2010, accounting for less than 1 percent of new light-duty vehicle sales. The strong growth in vehicle sales is mostly due to rising sales of gas-guzzling pickup trucks.
Optimism for EV market expansion is warranted, however, not only due to steady sales growth but also due to three key developments in 2013.
