A new study published this week in the Proceedings of the National Academy of Science, finds that methane emissions from oil and gas facilities in North Texas’ Barnett Shale are likely as much as 90 percent higher than previous estimates based on data from the Environmental Protection Agency.
This is no small matter. Methane is a powerful greenhouse gas rapidly accelerating the rate of climate change. But it’s also emitted with other harmful pollutants, like Volatile Organic Compounds (VOCs) that contribute to smog levels, as well as the cancer causing compound benzene. One study estimates that oil and gas production in the Barnett Shale Region in Texas contributes 19,888 tons of VOCs per year while estimates for the Eagle Ford Shale region just south of San Antonio project oil and gas operations could produce up to 1,248 tons per day VOC by 2018. Both the DFW area and San Antonio are struggling with high smog levels.
And based on the findings of the new methane study, we now know that there are instances where the magnitude of oil and gas emissions is even higher than previously thought. That is especially troubling for the more than 6 million people living in the DFW area who are at risk of developing or exacerbating respiratory and other health problems as a result of this unnecessary air pollution. Unnecessary because recent analysis concludes that emissions can be drastically reduced by implementing cost-effective and “off the shelf” pollution reduction technologies and practices – begging the question: why has Texas, the leading oil and gas producing state, not been a leader on reducing this harmful pollution?
