Big Rigs: Will the Climate Benefit from Switching Diesel Trucks to Natural Gas?

By EDF Blogs / Published: May 19, 2015

By: Jonathan Camuzeaux, Senior Economic Analyst

16058670001_80994ae935_z The surge in natural gas production that has reshaped the American energy landscape has many in the commercial transportation sector considering whether to start shifting their heavy-duty vehicle fleets from diesel to natural gas fuel. Many are looking to an advantage in carbon dioxide emissions to justify the higher cost and reduced fuel efficiency of a natural gas vehicle.

But in fact, a study published today in Environmental Science & Technology finds that while there are pathways for natural gas trucks to achieve climate benefits, reductions in potent heat trapping methane emissions across the natural gas value chain are necessary, along with engine efficiency improvements. If these steps are not taken, switching truck fleets from diesel to natural gas could actually increase warming for decades.

Methane, the main ingredient in natural gas, has 84 times more warming power than CO₂ over a 20-year timeframe. Reducing emissions throughout the natural gas value chain is an important opportunity to reduce our overall greenhouse footprint. Read More »

Bank of America Votes for Renewables with Its Very Large Wallet

By EDF Blogs / Published: May 11, 2015

By: Tom Murray, Vice President, Corporate Partnerships Program

A company’s public statements matter – they can influence consumer choice, sway public policy decisions, and demonstrate leadership on important issues. But in terms of actual change, it’s where a company puts its money that really matters. This week, Bank of America (BoA) spoke with both its voice and wallet: At its shareholder meeting last week, the bank announced a new coal policy that continues the company’s commitment to reducing its exposure to coal extraction companies and accelerating the transition from a high-carbon to a low-carbon economy.

According to BoA, its portfolio has grown to favor renewable energy over coal by a ratio of more than three-to-one. That’s an important step forward toward a clean, low-carbon energy future. And, it’s one that builds on moves by other institutions, like the recent news from Goldman Sachs about how the company is looking to divest some of its mining interests and Citi’s recent 10-year, $100-billion commitment toward investments in areas like energy efficiency, renewable energy, green affordable housing, and climate change resiliency projects.

Fossil fuels haven’t lost the race, yet. Here’s the full story.

By EDF Blogs / Published: May 1, 2015

By: Jeremy Proville, Senior GIS Specialist & Economic Analyst

A recent Bloomberg New Energy Finance article made a splash saying that fossil fuels “just lost the race against renewables.” It included a striking chart, depicting changes in power capacity additions with very clear diverging trends.

Although this would be a delightful turn of events, we should be wary of putting the cart before the horse.

What may be lost on many readers is the fact that Bloomberg bases its story on power capacity, rather than actual power generation. Read More »

Clearing the Air: L.A.’s Vision for Clean Transportation

By EDF Blogs / Published: April 15, 2015

By: Larissa Koehler and Jorge Madrid

There’s something remarkable happening in the city of Los Angeles, you can feel it in the air – and it’s definitely not the country’s worst pollution or the record-breaking heat – it’s the winds of change. Los Angeles is in the process of reinventing itself from a dystopian vision of traffic jams and unbreathable air into an urban leader in sustainability.

Last week L.A. Mayor Eric Garcetti unveiled a bold new plan (pLAn) to revolutionize sustainability in Los Angeles, including taking a bite of the big enchilada responsible for the most air pollution that gets in our lungs and greenhouse gas pollution that causes climate change – the transportation sector. Mobile sources (think diesel trucks, trains, ships, aircraft, and cars) account for 90 percent of Southern California’s harmful air pollution. Statewide, the transportation sector is responsible for nearly 70 percent of smog-forming gases and 40 percent of the state’s climate change pollution every year.

While some progress has been made – the number of non-attainment days (days when an area doesn’t meet the federal air quality standard) has decreased dramatically since the 1990s and the Port of Los Angeles has reduced diesel particulate matter by 80 percent since 2005 – there are still huge clean air disparities. We know the dirtiest zip codes in L.A. are also the ones with a disproportionately large amount of low-income communities and people of color. We cannot run a victory lap on this issue until EVERYONE in L.A. can safely get around the city and breathe healthy air at the same time. Read More »
