World renowned environmentalist Robert Swan, speaking today at the first day of the Ecotourism NZ Conference in Rotorua, has challenged New Zealand to stand for more than rugby.

"In my generation, growing up in England, we knew New Zealand for standing up to the US on the nuclear issue. You educated and inspired the whole world. What does New Zealand stand for today aside from rugby? Nothing - and it's time it did," he told the first day of the two-day conference.

"You have the ability and opportunity to inspire the world again, this time for renewable energy. You can lead the world in renewable energy. You are 80 percent there, why not go the whole way?"

Ecotourism NZ spokesperson Joe Doherty says ecotourism, more than any other tourism sector, is doing a lot for the environment "but we can always do better". The conference is a chance to share ideas, explore new opportunities and develop strategies to improve and enhance ecotourism, the fastest growing sector of New Zealand's tourism industry.

Robert Swan is one of the world's top polar explorers and environmental leaders. By age 33, he became the first person to walk to both the North and South Poles. His 900 mile journey to the South Pole - 'In the Footsteps of Scott', stands as the longest unassisted walk ever made on earth. Swan is currently on a five-year global 'Voyage for Cleaner Energy' aboard his renewable energy sailboat. He aims to showcase sustainable living practices and transport alternatives that run solely on renewable energy.

Swan says he supports ecotourism because he believes it is an excellent tool for promoting environmental awareness and educating people about sustainable energy.

"The greatest challenge on earth is the energy challenge. Renewable energy must be on the New Zealand agenda. You have a chance to show serious global leadership on renewable energy, you're almost there - you just need to make the commitment."

Swan spends most of his time in India and China because "if you don't get it right there, then we won't get it right anywhere."

"It (renewable energy) will help sell your products and help get people interested in coming here, but more importantly, you will also educate and inspire people. You must do this, and you must start now."
