AUSTIN, Texas – Cinco regiones de Texas, incluyendo la Cuenca Masiva Permian y la Cuenca de la Costa del Golfo, están entre las áreas del país que muestran la mayor contaminación por producción de petróleo y gas.
El metano es un poderoso gas de invernadero que gotea del “fracking” hidráulico y de la producción de petróleo y gas. Un reporte reciente señala el “Quién es Quién” de la contaminación por metano en Texas y el resto de los Estados Unidos.
De acuerdo al Centro por el Progreso Americano, once compañías emitieron la mitad de la polución por metano en puntos de producción de petróleo y gas en 2014, lo que equivale a más de 48 millones de toneladas métricas de dióxido de carbono.
Krystan Henagan, organizadora de campo en Texas para “Fuerza de las Mamás por un Aire Limpio” (MCAF), dice que las agencias regulatorias de Texas no están haciendo gran cosa por resolver el problema, dejándoselo a los productores.
“No hemos podido confiar en las compañías individuales para que se ocupen agresivamente de esas fugas, más allá de detectarlas y avisarles. Hasta ahora ha sido algo voluntario, y aquí en Texas creo que menos del uno por ciento lo ha hecho.”
El reporte indica que hay más de 180 mil pozos en todo Texas, los que estima conservadoramente que emiten el equivalente a más de 16 millones de toneladas métricas de dióxido de carbono al año.
También resalta que frecuentemente dejan escapar componentes orgánicos volátiles y otras toxinas junto con el metano, empeorando la calidad del aire y contribuyendo al cambio climático.
Alison Cassady, directora de políticas energéticas domésticas en el Centro para el Progreso Americano (CAP), afirma que hay muchas empresas que usan las mejores prácticas para reducir las emisiones de metano –pero la preocupación son las empresas que no lo hacen.
“Es tecnología existente, está a la venta, y las empresas de todo el país la están usando. El metano es un contaminante global súper cargado que resulta mucho más potente que el dióxido de carbono, y por eso nos interesa tanto cortar la contaminación de metano que emana de la mayor fuente industrial: el sector petrolero y gasero.”
La Agencia de Protección Ambiental (Environmental Protection Agency) recientemente ultimó los límites a las emisiones de metano procedentes de nuevas fuentes, y a la agencia se le está pidiendo también que fije estándares para los pozos y el equipo que ya están en operación.

Today, in honor of Earth Day, climate advocates are asking California lawmakers and Gov. Gavin Newsom to rally around a plan to put a $15 billion bond measure on the November ballot.
If passed, the bond measure would fund a range of climate resiliency measures.
Sam Hodder, president and CEO of the Save the Redwoods League, said March was the tenth month in a row to break monthly heat records.
"I think Earth Day is a terrific opportunity for the broader public to recognize how nature is critical for resilience, for our quality of life, for our mental and physical health, and for our communities more broadly," Hodder outlined.
Two similar bills to put a bond measure on the ballot are under consideration in Sacramento, Assembly Bill 1567 and Senate Bill 867, but they have been stalled since last summer. The bond would finance many programs, including some to restore wetlands that guard against sea-level rise, and to remove dead wood in forests to guard against mega-fires, which Hodder noted have killed 20% of the giant sequoias in recent years.
Opponents pointed out the state already faces a budget deficit and cannot afford to take on more debt. But only 5% of California's old-growth coastal redwoods remain, mostly due to aggressive logging many decades ago.
Hodder argued the giant trees can be critical ingredients in the fight against climate change because they trap so much carbon.
"Redwood forests sequester more carbon per acre than any other forest system in the world," Hodder emphasized. "We have the opportunity to transition the redwood forest from something that is vulnerable to climate change to something that is helping to solve and address the climate crisis."
Experts blame climate change for California's wild weather over the past few years, which has been marked by extreme drought, devastating fires and flooding rain.

A new report from the National Wildlife Federation warns that the effects of climate change in the Quad Cities, along the Iowa-Illinois border, will be severe.
But researchers got the public involved in studying to find ways to head off some of the most pressing concerns.
The report says climate change means a warmer, wetter future for the Quad Cities, which straddle the Mississippi River in Iowa and Illinois.
But rather than repeat what experts have already been saying about drastic flooding along the Big Muddy, Prairie Rivers Network River Health and Resiliency Organizer Nina Struss said researchers and Quad Cities residents brainstormed solutions to tackle the effects of climate change.
"Flooding and flash flooding were the top concerns," said Struss. "Extreme heat was also a big concern, as well as drought and other extreme weather events."
Researchers combined that information with hard science at the University of Illinois to create 3D models depicting what climate-induced flooding along the Mississippi could look like in the future.
The survey also asked people to identify which geographical areas and populations are most at risk from the effects of climate change, and worked with the community on solutions to mitigate some of them.
Struss said this research proposes what are known as nature-based solutions to combat the effects of climate change - restoring, preserving and even expanding existing ecosystems, like wetlands and tree canopies. But creating more eco-friendly infrastructure, too.
"Can we work to maybe have our pavements that we're putting in be more permeable, so that they can absorb that water and have that higher water-holding capacity?" said Struss. "Can we focus on areas to plant more native plants that have stronger root systems, versus ones that have shorter root systems, to help with that water-holding capacity?"
Struss said this research isn't a one-off. It will continue to change, she said, as the climate changes, the needs become more clear, and the effects more drastic.
She said progress in addressing climate change relies on more research, education and funding.

Wet weather this spring has improved drought conditions in Minnesota and southern Canada. However, experts remain on alert for increased wildfire activity and other climate changes affecting people's health.
Poor air quality was a frequent topic last year in the upper Midwest, as smoke pushed down from Canadian wildfires. Researchers said climate change is fueling hotter and drier summers, making forests more susceptible to large fires.
Dr. Bruce Snyder, co-founder of Health Professionals for a Healthy Climate, worries about a repeat summer of thick, hazy smoke in the air creating unhealthy conditions.
"When that happens, people have more respiratory disease; people who have chronic lung disease tend to get sicker," Snyder explained. "There's a lot of downstream consequences for people all over the world, but certainly here in Minnesota."
Snyder noted the transition to cleaner energy sources is complex, but acknowledged pollution events place more emphasis on the need for less reliance on fossil fuels, due to their contributions to a warming planet. The Minnesota Pollution Control Agency said the state has had 46 air quality alerts since 2015, and 34 of those were because of wildfire smoke.
Snyder emphasized it is not just air pollution from wildfire smoke to worry about. He pointed out there are other ways a person's health can suffer from climate change.
"We've got many more dangerous insects -- ticks, mosquitoes, and so forth," Snyder stressed. "This is having a profound effect on our wildlife. But also, we're seeing a lot more progressively rising rates of Lyme disease, of West Nile virus."
Year-over-year statistics may vary, but state health officials say the median number of Lyme disease cases has risen in the past decade. Snyder added adverse health effects of climate change can be much harder for populations lacking stable housing.
