Exxon Mobil Corp. has set its first company-wide targets for cutting the emissions from its operations, as the largest U.S. oil group attempted to curb its contribution to the threat of climate change.

The company is setting targets to reduce leaks of methane by 15%, and flaring of unwanted gas by 25%, by 2020, and will be deploying new equipment at its operations to achieve those goals.

Methane, which is the principal component of natural gas, is a potent greenhouse gas, with a contribution to global warming that is many times greater than carbon dioxide.
