Talks on freeing up commerce in environmental goods and services, which will have special treatment in a new global trade pact, are making progress, the head of the World Trade Organization said.

WTO Director-General Pascal Lamy said countries were jostling for position in the sector, whose importance meant the talks went beyond increasing market access as in other areas.

"There has to be a premium for environmental goods and services, a bit like agriculture," Lamy told a news conference before meeting Danish parliamentarians.

Lamy said it was a complex process to agree the list of environmental goods that would enjoy special access, but it was moving ahead.

"If I have a competitive advantage in bicycles, I will make sure that bicycles are on the list," he said. "If I have a competitive advantage in washing machines (that consume less water than others), I will make sure they are on the list."

The negotiations on environmental goods and services are part of the eight-year-old Doha round to free up world trade.

Lamy forecast energy-related and environment-related goods and services would probably be to Doha what financial services were to the Uruguay round that liberated trade in them.

"Countries have a strong interest in improving the efficiency of their economies by opening their markets to environmental goods or related services," Lamy said.

Expanding free trade in general is a cheap and effective way for governments to get their economies out of crisis, he said.

Lamy said he did not know if the debt crisis in Europe would dent world trade. He noted that the WTO's forecast from March was for the volume of world trade to rebound by nearly 10 percent this year after a 12 percent drop in 2009.

"It (the debt crisis) reinforces the attraction of a Doha deal as a very powerful tool to exit the crisis, a low-cost, powerful macroeconomic decision," Lamy said, referring to the package of trade liberalisation on the table in the Doha round.

Trade liberalization compared very favourably with budgetary stimulus in terms of the costs and benefits, he said. "Rationally, if you look at what people need to do ... to exit the crisis, this huge package of trade opening is there available at low cost, very low cost for the taxpayers," he said. (Reuters)
