Ranked by environmental performance, just one of Japan's 11 utilities appears in a global top ten of 71 major utilities surveyed by the World Wildlife Fund (WWF) of Japan. With the highest installed wind capacity in Japan, Hokkaido Electric Power took seventh place. While the now privatised Electric Power Development Company (J-Power) and Shikoku Electric Power took 14th and 16th places, the best anyone else could do was Chugoku Electric Power in 29th position. The worst performers were Kansai Electric Power ranked 48th, and Tokyo Electric Power and Chubu Electric Power, which share the 51st slot. Spain's Iberdrola topped the list, closely followed by FPL Group of the US and the UK's Scottish Power, owner of American wind project developer PPM. An unnamed official at a major Japanese electric power utility has criticised the WWF rating methodology as "one-sided" because the group refuses to recognise nuclear generation as an acceptable technology for curbing carbon dioxide and other greenhouse gas emissions, reports Japanese news agency Kyodo.
