, according to the Institute of Travel Management. Regarding
environmental protection, the survey of firms that collectively spend more than £ 800 million on travel found "most corporations are encouraging a reduction in emissions rather than offset. Forty-five percent of companies encourage reduction in CO2 emissions through reduced travel--for example using video/teleconference specifically with emission reduction in mind, and not just to cut costs." ITM said less than 30 percent "attempt to limit CO2 emissions through switching from road or air travel to rail; 13 percent participate in programs to offset the CO2 emissions caused by their travelers and 3 percent award contracts to travel suppliers on the basis of their environmental records."
