Californians benefit from continuous pollution monitoring at oil and gas sites

Sophia Brewer, Oil and Gas Intern, contributed to this article.

Since the 1892 discovery of oil in California, the oil and gas industry has been a major economic engine and energy supplier for the state. Although this oil and gas production may be broken down into dollars and barrels, it doesn’t tell the story of the potential impact of drilling activity on the lives of the people in Los Angeles and the Central Valley who live right next to these operations.

While some production sites may be meeting stringent operational and environmental standards, others may not –there simply isn’t data to discern which is which – and that is where monitoring comes in. Read More »

Here’s how Chevron’s next CEO can turn over a new leaf

Chevron, the nation’s second largest oil and gas producer, is in the news this week as reports surface that long-time CEO John Watson is expected to step down. It’s no secret that Mr. Watson has too often lagged on his response to climate change. As the board selects a new CEO, it has a chance to turn a new leaf and move Chevron toward the right side of history on climate change, better positioning the company to address investor and social demands for cleaner energy and climate risk management.

Here’s what their new CEO should bring to the table:

A vision for how the company adapts and leads in the low carbon transition

Chevron withheld support for the Paris climate accord even as peers like Exxon and Shell supported it. Opposing the vast majority of the rest of the world is not an economically sustainable posture for a global company –and it creates unnecessary risks for shareholders. The board should select a CEO with a vision to adapt and lead in the transition to a cleaner energy economy. Simply acknowledging the reality of climate change is no longer enough – a 21st century energy leader also develops a sound business plan to navigate that reality and help the global community address one of its costliest challenges.

Upstream methane reductions crucial to future of natural gas trucks

By Jason Mathers

Amid a sustained slump in sales for natural gas vehicles, a new study highlights significant challenges for these vehicles to deliver on their modest potential of climate emission reductions; the ultimate climate impact of these vehicles rests on the actions and practices of the upstream supply chain, or well-to-pump suppliers.

The central climate-related challenge of natural gas vehicles is unburned methane leaked from the natural gas supply chain, fueling stations, and vehicles. Methane is a powerful greenhouse gas known to be 84 times more potent than carbon in its first 20 years within the atmosphere. A 2015 study in Environmental Science & Technology found commercial fleets converting from diesel to natural gas could lead to greater global warming over the next 50 to 90 years before providing benefits to the climate.

Heavy Truck Emissions Outpace Fuel Stations

The new study, Future Methane Emissions from the Heavy-Duty Natural Gas Transportation Sector for Stasis, High, Medium, and Low Scenarios in 2035, expands the research conducted around methane emissions from commercial fleet vehicles and refueling stations. Led by researchers at West Virginia University, the study used data from the first study published in January to evaluate emissions and explore ways to reduce emissions from the pump-to-wheels portion of the natural gas supply chain with best management practices.

Methane standards are the law of the land; it’s time to stop litigation and start complying

Let me first make this important point: I’ve met and worked with a lot of folks in the oil and gas industry who are truly dedicated to making their operations as safe and clean as possible – people who care about the communities they live and work in and who take pride in the reputation of the companies they work for.

That said, I’ve always rolled my eyes a little when I see companies boast in sustainability reports that they comply with all applicable federal and state laws.  Really?  Not breaking the law is the high bar you’re shooting for?

But , as it turns out, one of the nation’s largest oil and gas trade associations is now saying that not only does it oppose common-sense laws requiring companies to reduce their emissions of methane and other harmful air pollution, it’s casting doubt on the extent to which companies should even comply.

The courts have repeatedly struck down efforts by the Trump administration and industry lobbyists to suspend these pollution standards.  And these rules are now in full legal effect. Read More »

Be prepared: Why the smart oil and gas producers are leaning in despite uncertainty

Be Prepared. It’s not just the Boy Scout motto, it’s also the way most smart businesses try to operate. Better to anticipate future compliance issues today and bake them into your forward planning, than to be caught flatfooted tomorrow.

That is a big part of the reason major multinational oil and gas producers like ExxonMobil and Shell have said they are already following methane pollution rules finalized by the U.S. Environmental Protection Agency last year. Despite EPA Administrator Scott Pruitt’s best efforts to delay implementation of these rules, the courts have repeatedly ruled in favor of their speedy and complete implementation.

Most recently the DC Circuit last week rejected the latest attempt to undermine methane pollution limits for sources in the oil and gas sector and put those standards into full force and effect. It’s a decision that shows the wisdom of ExxonMobil’s and Shell’s strategy to lean in on regulatory compliance (and highlights the danger for other oil and gas producers that seem to be content dragging their feet and exposing their investors to compliance risk).

Shell becomes latest oil and gas company to test smart methane sensors

This week, the oil and gas giant Shell took a positive step toward addressing methane emissions. The company announced a new technology trial at a wellsite in Alberta, Canada, where it is piloting a specially designed laser to continuously monitor emissions of methane, a powerful pollutant known to leak from oil and gas equipment.

The move by Shell is a glimpse into the future and demonstrates growing market interest in smart, sensor-based methane detection technology. Shell’s project joins a similar field test already underway in Texas, operated by the Norwegian producer Statoil, and a California utility pilot run by Pacific Gas and Electric Company.

Each of these deployments is promising, but the ultimate test will be broad-scale adoption of innovations that generate actual methane reductions. Read More »
