Late August provided a vivid reminder of San Antonio’s decade long challenge with air quality and a timely preview of an issue the entire region will be talking about next month: ground level ozone (a.k.a. smog).
The last week of August, San Antonio air monitors registered some of the highest smog readings of the year. In fact, the city’s smog levels were higher than any other city in Texas on August 27.
Put simply, if you have asthma, or other breathing difficulties, you probably had a pretty tough time that week. Read More

Growing up in the heat of South Texas, praying for rain was a daily ritual. Droughts are common there, and climate change is making them more intense and thus more devastating. Yet Texans are surrounded by inaccurate political messages that cast doubt on evidence that humans are causing climate change. This kind of rhetoric is physically and economically harmful, especially to the 40 percent of Texans who are Hispanic or Latino, because these populations are disproportionately impacted by climate change.
Environmental Defense Fund (EDF) has partnered with League of United Latin American Citizens (LULAC) to raise awareness and action on environmental issues that impact our health. LULAC is the largest and oldest nationwide Hispanic civil rights organization in the U.S. Recently, I had the honor of speaking with the Greater Houston LULAC Council at their monthly breakfast about how climate change impacts Latinos in Texas. Juan Parras, Founder and Director of Texas Environmental Justice Advocacy Services (TEJAS), joined me at the event and drove the point home by discussing how climate change and industrial pollution is affecting Latinos in Houston. Together, we sought to inform our audience of the role they can play to stop damaging rhetoric and get involved to support climate change solutions and public health protections. Read More
As readers of this blog will know, the freight transportation industry in Texas— a freight hub – has a significant impact on the state’s economy and environment. Recent market conditions and environmental concerns have ignited talk of expanding the use of natural gas trucks instead of diesel. But what would be the true climate benefit – or cost?
This post from our colleague Jonathan Camuzeaux, a senior economic analyst for EDF’s Office of Economic Policy and Analysis, explores this question from a national perspective, but we wanted to share this post with Texas Clean Air Matters because of its relevance to our state. We have the second-largest state-highway system in the U.S., as well as the Port of Houston Authority, which is the second busiest port in the nation when it comes to overall tonnage. Considering the switch to natural gas could have a big effect on the climate impact of the state’s truck fleets.

Over the past century, the electric grid in the United States has experienced only minor changes. There is evidence, however, the power sector is changing. We are moving away from traditional coal generation and toward alternative, cleaner energy sources. And despite our state being primarily known for oil and gas, Texas is no exception.
In fact, Texas’ electricity sector has been trending cleaner over the past decades, driven by deregulation of the electricity market, the development of the massive highway of transmission lines built to carry West Texas wind to cities throughout the state – the Competitive Renewable Energy Zone (CREZ), and technological progress. Basically, once the market was opened up to competition, the more economic options – which also happen to be cleaner – began to gain a foothold. And there’s no stopping this train.
Where we are and where we’re going
To start, the declining use of fossil fuels to power our lives is perhaps the most significant change in Texas. As shown in Figure 1 below, fossil fuels’ (coal and gas’) proportion of the state’s electricity generation mix shrunk from 88 percent in 2002 to 82 percent in 2013. Read More

Here we go again.
A new set of peer-reviewed scientific papers pointing to 50 percent higher than estimated regional methane emissions from oil and gas operations in Texas were published this week. And like clockwork, the oil and gas industry’s public relations machine, Energy In Depth, proclaimed that rising emissions are actually falling, and that the industry’s meager voluntary efforts are responsible.
This is, of course, wrong on both counts. In fact, it’s a willful misrepresentation of the findings.
First, the assertion that emissions are going down is flat wrong. EPA’s latest inventory released in April reports that in 2013 the oil and gas industry released more than 7.3 million metric tons of methane into the atmosphere from their operations—a three percent increase over 2012—making it the largest industrial source of methane pollution. So much for those voluntary efforts. Read More

Methane emissions from vast oil and gas operations in the densely populated Barnett Shale region of Texas are 50 percent higher than estimates based on the Environmental Protection Agency’s (EPA) greenhouse gas inventory, according to a series of 11 new papers published today in Environmental Science & Technology.
The majority of these emissions are from a small but widespread number of sources across the region’s oil and gas supply chain. These emissions come from the sort of leaks and equipment malfunctions that are relatively easy to prevent with proper and frequent monitoring and repair practices.
The sprawling Barnett region, fanning out westward from the cities of Dallas and Fort Worth, contains about 30,000 oil and gas wells, 275 compressor stations, and 40 processing plants. It is one of the country’s largest production areas, responsible for 7 percent of total U.S. natural gas output.
