China, the world’s largest emitter of methane, said it will boost monitoring, reporting and data transparency to reduce releases of the super-potent greenhouse gas.

The nation will also deploy new technologies to spot methane pollution, according to a document released on Tuesday by the Ministry of Ecology and Environment. While the plan covered strategies to lower emissions from industries such as coal mining, rice farming and gas operations, it did not lay out specific targets.
