New well integrity rules make Colorado a leader in well safety for workers and neighbors

By Adam Peltz / Published: January 31, 2020

The state of Colorado is poised to adopt some of the nation’s most sophisticated and protective regulations designed to prevent its 60,000 oil and gas wells from leaking or exploding.

Colorado has a history of leading on oil and gas regulatory issues to reduce risks to families, workers and the environment, including the nation’s first regulations to address climate-damaging methane emissions from the industry in 2014. In the wake of the 2017 Firestone tragedy and the passage of a major oil and gas reform bill (SB 181) in 2019, the state has undertaken a whole slate of rule modernizations. Well integrity, for which rules have not been updated since 2008, is up next.

The next major ESG opportunity for investors in Europe

By Ben Ratner / Published: January 15, 2020

In recent years, institutional investors have demonstrated their formidable influence, as companies respond to investor environmental, social and governance demands and governments take note of forceful investor calls to action. Europe’s leading investors have been especially active, stepping to the vanguard to address the climate crisis with a sense of urgency and injection of ambition.

As Europe pursues its bold “Green Deal,” European investors have a powerful chance to help address a climate blind spot and policy vacuum to ensure worthy climate goals are not derailed. Investors can do so in a way that generates shareholder value while mitigating one of the largest near-term sources of climate risk. The opportunity lies in addressing methane emissions from the global oil and gas industry, which emits more than 75 million metric tons of the greenhouse gas every year.

New study finds elevated health risks due to pollution from oil and gas activity in Colorado

By EDF Blogs / Published: November 21, 2019

By Ananya Roy and Tammy Thompson

As production of oil and gas in the United States has expanded, it’s no longer uncommon to see rigs and well pads nestled in communities. For example, Weld County in Colorado ranked fourth in the nation for population growth in 2017, and has issued thousands of new permits for oil and gas extraction in the past few years. Emissions from the intensive energy development sprouting along highways, in fields and within sight of homes, playgrounds and school yards has led to concerns about rising pollution from this industry and the subsequent health risks.

Communities are concerned about all of the emissions from these operations but focus on the brew of volatile organic compounds that include benzene, toluene and ethyl benzene, since some are known carcinogens or have established impacts on the brain, lungs and blood. VOC emissions, however, vary considerably between different processes. Well sites and changing weather conditions either spread or concentrate the pollution over different distances and directions, suggesting that intermittent measurement campaigns are inadequate to capture population exposures and risks.

Long considered a “clean” energy source, hydropower can actually be bad for climate

By Ilissa Ocko / Published: November 15, 2019

A new EDF study published this week in Environmental Science and Technology shows that hydropower — the leading renewable energy technology projected to grow rapidly — is not always as good for the climate as broadly assumed. Moreover, continuing to assume that it is could mean that projects meant to reduce greenhouse emissions will unintentionally increase them instead.

Motivated by pervasive misconceptions of the climate impacts of hydropower, we assessed the warming impacts over time of sustained greenhouse gas emissions estimated from nearly 1,500 existing hydropower plants around the globe. We also looked at the implications of future hydropower development.

Illinois PUC decision may signal changing tide for natural gas utilities

By Christie Hicks / Published: November 14, 2019

While economic and environmental concerns have driven significant electric sector improvements, climate impacts of continued reliance on natural gas for heating and cooking has gone largely unchecked. A recent decision by the Illinois Commerce Commission sends a signal that natural gas utilities will not be permitted to invest customer dollars unchecked.

State public utilities commissions regulate natural gas distribution utilities and set their rates of return, one component of which is “return on equity.” These regulators thus have a tremendous influence on the long-term profitability of utilities and their investment decisions. Higher rates of return incentivize greater system buildout — the more the utility builds, the greater their profit.

Methane regulations can help transform Mexico’s energy sector

By Shareen Yawanarajah Ph.D. / Published: November 12, 2019

One year ago this week, Mexico took an immense step forward by passing the world’s most comprehensive regulations to reduce oil and gas methane emissions. Since then, oil and gas companies and the Mexican government have been collaborating to develop concrete plans to make this happen and to ensure that the country is on track to deliver on its climate goals. In June 2016 Mexico, along with the US and Canada, committed to reducing methane emissions from the oil and gas sector by 40-45% by 2025, a target that is in line with the stated goals of the United Nations’ Convention on Climate Change.

But, is this enough? That is a question Mexico’s government and its national oil company, Pemex, should be asking today, because the country deserves more.
