"I believe it is our responsibility to come up with an overall agreement to follow within our own council of members," Kent said in an interview with Reuters on the sidelines of a global meeting on the environment and tourism.

"By the end of the year, we'll probably come up with some really good and concrete challenges for WTTC members."

The tourism industry is expected to contribute to 10.4 percent of the world's economy in 2007 and is responsible for 231 million jobs, according to the WTTC.

There are no exact numbers as to the volume of carbon emissions that tourism releases into the atmosphere, but the industry is dependent on construction, airline and sea travel and other activities that are often blamed for climate change.

Kent said he expected some of the WTTC measures to make some tourism companies more cost efficient. WTTC members include US hospitality company Wyndham Worldwide Corp. and the Intercontinental Hotel Group.

"Climate change is actually going to make them save money," he said, adding that he believed companies who cut as much as 40 percent of carbon emissions would become more energy-efficient and save money.

He said airlines had been overly criticized, however, for the role they play in climate change.

"Airlines are being demonized, because it's easy for government officials to lift their finger at them, but they only contribute 1.6 percent of the problem, compared with 40 percent (of emissions) in new buildings," he said.
