LONDON (Reuters) - The withdrawal of the United States from the Paris climate pact is unlikely to have a direct impact on the expected decline in global carbon emissions, BP's <BP.L> chief economist said on Tuesday.
"Nearly all the improvement in (carbon reduction) comes from the developing world, it isn't coming from OECD or America," Spencer Dale said during a presentation of BP's annual Statistical Review of World Energy.
The reduction in U.S. greenhouse gas emissions in recent years has been a result of cheaper natural gas pushing out more polluting coal rather than regulations, he said.
