TOYAKO, Hokkaido — Debate on global warming can heat up sometimes, but the Group of Eight summit shouldn't be contributing to climate change.

According to the Foreign Ministry, the gathering in Toyako will be the second G8 summit, after the 2005 affair in Gleneagles, Scotland, to offset its carbon emissions.

In addition, eco-friendly devices such as an air conditioning system using snow have been employed at the International Media Center.
