Rio, China Juggle Whether to Sell, Use Emission Credits

Officials from Rio de Janeiro and China said they wouldn’t use emission-reduction credits that have been exported when accounting for new domestic greenhouse-gas targets, potentially easing climate negotiations.

Brazil’s second-largest city will retire any reductions it uses when accounting for its 2020 target, said Rodrigo Rosa, special adviser on climate protection to Rio de Janeiro Mayor Eduardo Paes. “Either we retire through the targets, or we sell the credits,” Rosa said in an interview in Cologne, Germany.
