Ohio’s oil and natural gas producers reported spewing more than 13,000 metric tons of industrial methane pollution and toxic chemicals into the air in 2014. These nonstop leaks, invisible to the naked eye, had the same climate impact as driving 70,000 cars for a year.
There are many types of polluting oil and gas equipment aside from wells: tanks, pumps, compressor stations, pipelines. These sources emit not just methane but also more-harmful substances, such as benzene. Emissions of other chemicals form ozone smog, which can trigger deadly asthma attacks in children and old people.
