Huge Methane Leaks Add Doubt on Gas as ‘Bridge’ Fuel

A study published Monday adds to the growing evidence those escaping gases, called "fugitive" emissions, are numerous, especially methane emissions while a well is being drilled, a phase of well development previously thought to emit little if any methane. Methane is about 35 times as potent as a climate change-driving greenhouse gas than carbon di… Read More
