Shining new light on the toxicity of chemicals in produced water

In the United States, onshore oil and gas extraction operations generate nearly a trillion gallons of produced water annually. It is the largest waste stream associated with upstream development of petroleum hydrocarbons.

As EDF has written in numerous posts, this wastewater from oil and gas wells can be complex and toxic. In addition to the chemicals companies use during drilling and extraction, it can contain a wide range of potentially harmful material that already existed in the ground, and can be many times saltier than seawater. There’s a lot of it, too. Some wells produce up to 10 times as much wastewater as they do oil.

Methane regulations can help transform Mexico’s energy sector

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.

Texas cities and fleet owners should take a closer look at electric buses

Last month, the city of Houston announced the formation of EVolve Houston, a partnership focused on accelerating the adoption of electric vehicles, slashing transportation-related emissions and delivering cleaner air for the region. Considering Houston has some of the highest per capita greenhouse gas emissions in the country and nearly half of these emissions come from transportation, this strategy is a critical component for meeting ambitious climate goals and improving quality of life.

As the Energy Capital of the World goes electric with the goal of 30% of new car sales being EVs by 2030, cities, transit agencies and fleet owners across the state should also consider how investing in electric buses presents an opportunity to cut pollution, deliver on climate goals and generate economic benefits.
