“Oil is not responsible,” the producer group’s Secretary General, Abdullah al-Badri, told reporters on Thursday on the sidelines of the International Oil Summit in Paris.
“It is the industrialized countries which are making all this pollution in the world.”
Scientists say the burning of fossil fuels, such as oil, is a key factor in climate change.
Badri said the revenues from high taxes that some industrialized countries, including most western European nations, place on oil products should be diverted to environmental projects.
OPEC, whose member countries pump more than a third of the world’s oil, has supported the United Nations Convention on Climate Change and its Kyoto Protocol, which encourage reductions in emissions of greenhouse gas carbon dioxide (CO2).
However, the Organization of the Petroleum Exporting Countries has also opposed plans to reduce oil consumption and advocated adaptation to climate change.
