New Study Emphasizes Need to Find and Fix Methane Leaks; Reveals Limits of Voluntary Action

T_S image 2A study published today in Environmental Science & Technology confirms official figures from the Environmental Protection Agency showing that an enormous amount of methane – about 80 billion cubic feet per year – is escaping from thousands of key nodes along the nation’s natural gas interstate pipeline system. This equals the 20-year climate impact of 33 coal-fired power plants and more than $240 million worth of wasted natural gas per year, enough to meet the yearly heating and cooking needs of over a million U.S. households.

The study also shows the limitations of voluntary measures to address the industry’s methane problem. Companies that volunteered for this study, for example, reported emissions 30 percent lower than companies that were not involved. For some equipment, the difference was more than seven-fold. The performance gap between volunteer and non-volunteer companies reinforces doubt about industry claims that it can manage methane emissions on its own, underscoring the need for standards that create a level playing field across the sector.

Major Challenge, Big Opportunity

The study also confirms that major emission sources are widely distributed, intermittent, and unpredictable. In this case, a relatively small number of large leaks from ill-performing equipment and facilities accounted for 40 percent of the methane leaking from the country’s pipeline transmission and storage infrastructure.

To Meet Methane Emissions Duty, California Must Look Beyond its Own Borders

By: Tim O’Connor, Director of California Climate Initiative, and Amanda Johnson, Legal Fellow

Methane MoleculeCalifornia is in the midst of multiple regulatory efforts to reduce methane emissions from natural gas and oil operations throughout the state. It’s a key opportunity to make a real dent in the state’s climate impact since methane, the primary component of natural gas, packs over 84 times the warming potential of carbon dioxide in the first 20 years after it is released unburned.

Methane emissions in-state and out of state

One of the key efforts going on in the state is the development of new rules by the California Public Utilities Commission (CPUC) to reduce methane emissions from natural gas transmission, distribution, and storage, the systems that deliver gas to homes and businesses. And, at the California Air Resources Board (CARB), a new statewide plan to cut short lived climate pollutants from sources across the state is in development, as are new regulations to reduce emissions from oil and natural gas production, processing, and storage in California.

EPA Looks at Fracking Risks to Water: No Data, No Problem?

The Environmental Protection Agency (EPA) released its long-awaited draft report on impacts associated with hydraulic fracturing on drinking water last week, completing the most extensive scientific review of published data to date. At nearly 1,000 pages, it’s a substantial report. But it’s nowhere near a comprehensive evaluation – or even enumeration – of the risks that oil and gas development poses to both surface and ground water.

The biggest issues aren’t what’s in the document, but what isn’t. For all its heft, the biggest lesson in the report is just how little we actually know about these critical risks.

While Most Wait for the Federal Government, California May Have Just Broken the Methane Puzzle Wide Open

Oil and gas geothermal fields in California, 2001

Methane from oil and gas operations is a serious climate risk, but also a ripe opportunity to make a huge dent in overall greenhouse emissions. This past week, one state took a big, and long-awaited, step to address the challenge.

While we wait for the Environmental Protection Agency to release draft federal methane rules this summer, the California Air Resources Board has just released a draft of the most comprehensive and forward thinking regulations to cut methane pollution from oil and gas yet.

While the April 22 proposal still needs work – such as in the area of how often equipment needs to be inspected and how best to reduce venting associated with well unloading and other activities – it’s a big and fundamental step in the right direction. It has the potential to deliver what the rest of the country needs – comprehensive equipment standards on new and existing sources for both oil and gas operations, and enhanced leak detection and repair requirements across the methane value chain.

But the benefits will be felt closest to home first. Read More »

4 Ways to Invest in the Low-Carbon Economy

career-544952_640Citigroup Inc. recently pledged $100 billion for lending, investing, and facilitating deals related to sustainability, renewable energy,  and climate change mitigation. This is yet another sign that global capital markets are enormously interested in delivering capital into clean, renewable sources of energy. But you don’t have to be Citigroup to invest in the clean energy future.

The industry’s rapid growth presents an interesting diversity of  long-term opportunities for individuals like you and me who might be looking to make investments in a low carbon economy.

Fueled by an increased demand for solar and wind energy, clean energy investment last year beat expectations, rising 16 percent to $310 billion worldwide, according to Bloomberg New Energy Finance (BNEF). Fortunately, this robust growth is representative of a general upward trend in clean energy investment over the past decade.

Although the vast majority of this money is coming from governments, corporations, and private equity and venture capital firms, people of all income levels can consider whether it is right for them to add clean energy to their investment portfolios. And, you don’t need millions in the bank to make these types of investments – any investor can consider whether to put their money to use  through the four financial instruments described below.

The Revolution will be Solarized

construction-646465_640There’s a clean energy revolution happening in California – and it has the potential to topple the old polluting forces while fighting climate change with the power of the sun.

California is not only producing the most solar power in the country – 8.5 gigawatts, enough to power two million homes – it’s producing more solar power than the rest of the country combined. In 2014 alone, the state more than doubled its solar power, becoming the first state to generate five percent of its total electricity from utility-scale solar. This record does not even count rooftop solar and distributed generation (where California also leads the country), bringing the state closer to an estimated seven percent of its total power generation from free sunshine.

The solar industry employs more than 54,000 Californians – nearly one-third of all solar workers in the nation – and solar jobs in the state grew by 16 percent in 2014 alone (compared to 2.2 percent overall state job growth in 2014). California solar jobs are expected to grow by another 17 percent in 2015.

California cities are the vanguard of this revolution, with Los Angeles, San Diego, San Jose, San Francisco, and Sacramento leading the charge. New research finds that California’s cities and urban centers could generate enough solar to meet the state’s power needs three to five times over, without developing a single additional acre of the state’s natural areas.
