Global trade in environmental goods is estimated at $1 trillion a year and has been growing fast. (The United States exported about $106 billion worth of such goods last year.) But some countries have imposed import duties as high as 35 percent on such goods. That raises the already high cost of some of this equipment to utilities, manufacturers and, ultimately, consumers.
Taken together, the countries represented in these talks (the 28 members of the E.U. negotiate jointly, while China and Hong Kong are represented by separate delegations) account for about 86 percent of trade in these products, which makes the potential benefit from an agreement substantial. Other big countries that are not taking part in these talks, like India, South Africa and Brazil, could choose to join later.
