Data centers threaten to erase decades of air quality gains in Texas
Current overview (not historical)
A new report warns that planned data centers could push Texas air pollution back to 2006 peak levels for fine particulate matter and increase smog-forming nitrogen oxide emissions by 136% above 2004 levels. With data center capacity already at 26 gigawatts, reliance on on-site gas turbines would worsen pollution further. Tech companies and developers are exploring their own power sources to secure electricity, but this shift risks undermining prior air quality progress.

Report first recorded Oct 22, 07:09
A new report from the Houston Advanced Research Center (HARC) warns that if all planned data centers in Texas plug into the anticipated grid mix, fine particle pollution could more than triple, reaching its highest level since 2006 within five years. Specifically, smog-forming NOx emissions would increase 136 percent, approaching 2004 levels, and planet-heating carbon dioxide pollution would climb 90 percent above 2025 levels. Texas already has 26 gigawatts of existing and under-construction data center capacity, and developers are considering on-site power, including less efficient gas turbines, which could lead to the highest pollution levels possible; however, pairing grid power with onsite solar and wind could lower NOx emissions by up to 10 times.
