Energy Secretary Steven Chu on Tuesday advocated adjusting trade duties as a "weapon" to protect U.S. manufacturing, just a day after one of China's top climate envoys warned of a trade war if developed countries impose tariffs on carbon-intensive imports.
Mr. Chu, speaking before a House science panel, said establishing a carbon tariff would help "level the playing field" if other countries haven't imposed greenhouse-gas-reduction mandates similar to the one President Barack Obama plans to implement over the next couple of years. It is the first time the Obama administration has made public its view on the issue.
"If other countries don't impose a cost on carbon, then we will be at a disadvantage...[and] we would look at considering perhaps duties that would offset that cost," Mr. Chu said.
Li Gao, a senior Chinese negotiator from the National Development and Reform Commission, told Dow Jones Newswires Monday that a carbon tariff would be a "disaster," would prompt a trade war and wouldn't be legal under World Trade Organization agreements
"It does not abide by the rule of [the] WTO and, secondly, it's not fair," Mr. Gao said, adding that his delegation would relate China's concerns to U.S. officials.
