DAVOS ~ Tourism chiefs and UN agencies have pledged to “green” the travel trade while highlighting the US$880-billion industry’s own vulnerability to global warming.

In a four-page declaration, UN tourism, environment and weather agencies, national tourism officials and executives from 100 countries agreed the industry must “rapidly respond to climate change” and take “concrete measures” to curb greenhouse gas emissions.

They also said at the end of a three-day UN conference on tourism and global warming that tourists should be encouraged to consider the environmental impact of their travel choices and reduce their “carbon footprint.”
