New Study Improves Understanding of Natural Gas Vehicle Methane Emissions, But Supply Chain Emissions Loom Large

By EDF Blogs / Published: January 6, 2017

Many commercial fleet operators have considered switching their fleet vehicles from diesel to natural gas to take advantage of the growing abundance of natural gas and reduced emissions. Natural gas trucks have the potential to reduce nitrogen oxides emissions (NOx) from freight trucks and buses.

Yet, adopting the emission reduction technologies and practices needed to curb the methane escaping during the production, transport and delivery of natural gas is critical to unlock the full environmental potential of these vehicles. Methane, the main component of natural gas, is a potent greenhouse gas released to the atmosphere at every step from production wells to the vehicle fuel tanks. Even small amounts of methane emitted across the natural gas supply chain can undermine the climate benefit of fuel-switching vehicles to natural gas for some period of time, as EDF research has shown.

The Value of Pursuing a Rational Middle in Polarized Times

By Ben Ratner / Published: November 28, 2016

At Energy Dialogues’ North American Gas Forum last month, I had the opportunity to participate on a panel moderated by Gregory Kallenberg of the Rational Middle. While the panel pre-dated the presidential election, the topic of constructive engagement through rational discourse is now more important than ever.

We explored how environmental groups, industry, and other stakeholders need to come together to rationally discuss and collaboratively act on the challenges of meeting rising energy demand while addressing real and growing environmental risks.

The still principally fossil-based energy system, which includes natural gas, is not the only cause of climate change, but it is the largest. And so a range of stakeholders, from protesters holding signs, to investors with a long term interest in the future of natural gas, to industry consumers, are looking with increasing criticism at fossil fuels. That was true before the election, and it’s true today. They’re asking: How can we reconcile the environment we want to protect for the future with the traditional energy and feedstock resources we are using now? Read More »

Why Water Utilities Need an Energy Plan – and How Texas is Making Progress

By Kate Zerrenner / Published: November 22, 2016

water-tower-1420989568vmu When you prepare the Thanksgiving meal, do you ask each person to make a dish of their choosing, with no coordination for an overall cohesive meal? Probably not. Most likely, you plan, because you want everything to fit together.

Now imagine a water utility with different departments like water quality, finance, and administration. Most water utilities have high energy costs, so each department needs to manage and reduce its energy use – but typically there’s no plan to synchronize these efforts. With such a piecemeal approach, the utility may get overall energy savings, but it’s not maximizing the potential to meet ambitious efficiency goals or reduce power costs.

Enter the Energy Management Plan (EMP), a tool that sets up an organization-wide strategy for energy use. By creating a coordinated vision, an EMP establishes clear efficiency goals and gives departments the flexibility and direction for meeting them. That’s what this summer’s EDF Climate Corps fellow focused on at Tarrant Regional Water District (TRWD), which supplies water to 2 million users in the Fort Worth area. The TRWD fellow found opportunities where an EMP could improve the utility’s energy efficiency and management, leading to potential savings and less wasted water. Read More »

These Energy Efficiency Laws Give New York City a Fresh Start on Power Savings

By Abbey Brown / Published: November 2, 2016

eebillssigning_103116 The New York City Council has an excellent environmental track record, and I’m pleased to say that most recently it has passed a group of bills tackling energy efficiency in buildings, adding to its stellar standing.

Mayor Bill de Blasio this week signed a package of laws developed by the City Council that address energy efficiency in thousands of buildings citywide. Buildings account for nearly three-quarters of the city’s greenhouse gas emissions, which makes buildings crucial to New York City’s goal of reducing emissions 80 percent by 2050. In fact, the mayor’s office estimates that these bills will reduce greenhouse gas emissions by roughly 250,000 metric tons throughout the city, and create an estimated 100 jobs by spurring retrofits in 16,000 buildings. I attended the bill signing on October 31^st, and am proud to say that Environmental Defense Fund (EDF) has been working closely with both the mayor’s office and the City Council to get to this point, along with our partners, the New York League of Conservation Voters, Natural Resources Defense Council, and Urban Green Council.

These new laws – which affect 57 percent of New York City’s buildings (a higher percentage than any other U.S. city) – are important because they mandate that buildings track their energy use. Tracking use will inform necessary energy-efficiency upgrades that will have lasting impacts and ultimately improve the city’s environment and New Yorkers’ public health. Read More »

Working Smarter, Not Harder: How Companies Are Setting New Energy Goals

By Liz Delaney / Published: October 24, 2016

building It’s no secret that companies use goals to push their businesses in a positive direction. Whether it’s about creating more value or reducing impacts, goals provide focus, direction, and a sense of urgency. Recently, a wave corporate, climate-related goals, such as renewable energy and emissions-reductions targets, have grabbed the public’s attention. Companies, cities, and other large institutions are stepping up and committing to reduce their environmental impact. But behind the scenes, are these goals actually leading to corporate action? And if so, what kind?

As program director of EDF Climate Corps, every summer I get a glimpse inside the operations of 100 large organizations that are working to manage energy and carbon in progressively responsible ways. This past summer, 125 EDF Climate Corps fellows – talented graduate students armed with training and expert support – worked to advance clean energy projects in large organizations across the U.S. and in China. Their project work reveals that organizations are more strategic, focused, and results-oriented than ever. More than 70 percent of EDF Climate Corps host organizations have energy or emissions-reductions goals, and to meet these targets, our class of 2016 fellows were strategically deployed to help achieve them. In fact, the majority (two-thirds) of our entire cohort of fellows worked on strategic plans and analyses that will help turn these goals into action. So what did we see this summer? Read More »

Time to Tell the EPA What Works in Methane Mitigation

By Aileen Nowlan / Published: October 6, 2016

methane_technician The Environmental Protection Agency (EPA) has committed to regulate existing sources of methane from the oil and gas industry, and it is asking for information from the methane mitigation industry to make sure the rule’s approach and requirements account for recent innovation. The EPA’s announcement comprises the U.S. portion of the North American commitment to cut methane by up to 45% from the continent’s oil and gas industry by 2025. Existing sources in the oil and gas industry make up over 90% of the sector’s emissions, which contribute over 9 million tons of methane pollution annually.

The opportunity is open now to tell the EPA what works in methane mitigation.

Emission standards for existing sources of methane will not only reduce greenhouse gases but could also create new markets and customers for the growing mitigation industry. The regulation will likely start with one or more approved work practices to find and fix methane leaks, describing a technology or group of technologies that must be used in a certain manner. For example, EPA’s New Source Performance Standards for new and modified sources of methane required the use of optical gas imaging cameras or “Method 21” instruments. With far more existing sources of methane than new or modified sources, being part of an approved work practice for existing sources would open up a significant market opportunity. Read More »
