Methane is a potent greenhouse gas that can leak from oil and gas wells, pipelines and landfills. Satellites can spot the releases fast enough to get them fixed and help protect the climate.

New Zealand is considering a plan to tax methane from cows. But while cows and cars both emit greenhouse gases, they don’t have the same impact over time.
Reducing methane emissions could slow global warming quickly and buy time for the world to wean itself off fossil fuels. But it must not distract from the challenge to cut carbon dioxide emissions.
