World leaders pledge a crackdown on methane emissions. Here’s how satellites can help.

Satellites will play a key role in helping the world slash emissions of the potent greenhouse gas methane in line with a global pledge introduced by the U.S. President Joe Biden and European Union leaders at the COP26 climate change conference in Glasgow this week.
