The new kid on the energy block, shale gas, may be worse in climate change terms than coal, a study concludes.
Drawn from rock through a controversial “fracking” process, some hail the gas as a “stepping stone” to a low-carbon future and a route to energy security.

This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well.
