What started as the Mayor's symbolic act three years ago has grown into a national movement. Mayor Nickels committed in 2005 to reduce the city's emissions by the amount required by the treaty.

Nickels announced today that 794 cities have joined with Seattle in pledging to take local action to reduce their emissions.

Seattle Mayor Greg Nickels commemorated the anniversary of the Kyoto Protocol with a speech on opening day of the 64th Annual Seattle Home Show.

In terms of population, Nickels said that if these 794 climate cities were a country, it would be the 15th most populous on Earth, catching up with Germany.

The initiative began as a bipartisan effort, with New York City Mayor Michael Bloomberg (R) among the 131 other cities joining Seattle on the first day.

"All three of the major presidential candidates still standing all have strong climate protection platforms," Nickels said. "So the failure of the current federal administration to take action to protect our children and grandchildren will not be repeated by the next administration whether it's a Democrat or a Republican. I'm proud we've changed the conversation in our country."

The campaign in Seattle, "Climate Action Now," allows each resident and business to decide how to reduce the greenhouse gas pollution they emit. Living in the city is a good start, he said.

The Seattle Mayor discusses solar power with Dan Murray of Day4 Energy, at the Seattle Home Show 2008. Nickels toured several exhibits, including a lighting retailer and an appliance manufacturer.

The Mayor and his wife Sharon toured several exhibits at the home show, including a solar power system installer, a lighting retailer, and an appliance manufacturer. The first family is gradually refurbishing their century-old home in West Seattle.
