Hinojosa: A national climate plan needs a Texas component Rep. Gina Hinojosa With spring’s emergence, memories of winter’s Polar Vortex begin to recede and lose their sting. Unfortunately, we know that these weather disasters will continue to occur with increased frequency and magnitude due to climate change. Texas needs a plan to address climate change and we have one — the Texas Climate Plan. About two years ago, I decided to use my office to examine what Texans could do to impact climate change — it turns out, we can do a whole lot. Texas is the largest emitter of carbon dioxide in the country and a major emitter of methane. Carbon dioxide and methane are the primary greenhouse gases contributing to climate change. If Texas were a country, we would rank 7th in the world for our carbon dioxide emissions. Major sources of these greenhouse gases are the vehicles we drive, and the oil and gas industry.
