The International Energy Agency has warned that continuing China’s current coal usage patterns will lead to dire environmental consequences both for the country and the world, the Wall Street Journal reported. The Paris-based agency, in a report on clean coal technology conducted in cooperation with the Chinese government, said that China must enforce existing regulations and to allow more foreign investment in the energy sector. However, IEA Director Nobuo Tanaka, speaking Monday at the launch of the report in Beijing said that China will have to eventually charge for carbon emissions—a move the Chinese government has resisted as it might lead to the setting of national limits on emissions. China currently has no caps on carbon emissions and has earned billions of dollars from foreign countries investing in pollution-reduction projects in China in exchange for emissions credits back home.
