COPENHAGEN — Whenever climate change comes up for discussion, many industries say going green and reducing their energy consumption would be bad for business, even affecting the quality of service and products they provide.

But a movement in the hotel industry to introduce a low-carbon means of doing business that originated in Denmark and was recently introduced in Japan could be a good way to meet both ends — reducing energy consumption and leaving customers satisfied.

"It's trying to find the best solution so everybody can get something out of it. The environment, the hotel industry and the customers," said Mikal Holt Jensen, general manager of the Green Key program in Denmark.
