(Adds more details, language on oil spill)
By Caren Bohan
TORONTO, June 27 Leaders of the world's biggest
economies will pledge on Sunday to phase out subsidies for
"inefficient" fossil fuels, in a statement toughened at the
last minute at the urging of the United States, Group of 20
The G20 communique in Toronto calls for the "phase out over
the medium term of inefficient fossil fuel subsidies that
encourage wasteful consumption, taking into account vulnerable
groups and their development needs," said the sources, who
provided the language to Reuters.
The leaders also said they would review progress toward
that goal at future summits. The sources said the United States
had pushed to removed watered-down language from an earlier
An earlier version of the statement referred to "voluntary,
member-specific approaches" to getting rid of fossil fuel
subsidies but made no mention of a review of the progress.
Environmentalists viewed that as a weak commitment compared
with promises made at the previous G20 summit in Pittsburgh
At that gathering, hosted by U.S. President Barack Obama,
leaders also vowed to phase out the subsidies. They said that
jettisoning them by 2020 would reduce greenhouse gas emissions
blamed for global warming by 10 percent by 2050. The G20 had
cited data from the International Energy Agency and the
Organization for Economic Cooperation and Development.
The Toronto statement revived language from Pittsburgh that
called for the development of time frames and strategies to
implement the phase-out of subsidies.
The communique made reference to the BP Plc (BP.L) (BP.N)
oil spill on the U.S. Gulf Coast. The leaders urged the sharing
of best practices to protect marine life and prevent accidents
and to deal with the consequences when accidents occur.
