California Network to Monitor Global-Warming Emissions

California Network to Monitor Global-Warming Emissions

California is preparing to introduce the first statewide system of monitoring devices to detect global-warming emissions, installing them on towers throughout the state.

The monitoring network, which is expected to grow, will initially focus on pinpointing the sources and concentrations of methane, a potent contributor to climate change. The California plan is an early example of the kind of system that may be needed in many places as countries develop plans to limit their emissions of greenhouse gases.

"This is the first time that this is being done anywhere in the world that we know of," said Jorn Dinh Herner, a scientist with the California Air Resources Board.
