After years of refusing to replicate offers at the Cornwall visitor attraction, which opened in 2001, Smit said:
"We have been asked by 14 different countries over the years, and we have turned them all down. We just weren't interested.
"But with a new year comes a new way of thinking, and this year we are thinking differently. We want to build them in the style that reflects the culture where they are being built.
"It's not going to be like Disney World. We want the projects to be iconic in their own right.
"We are already looking into building one in the Arab world. We want each one to be a unique icon."
Smit added: "We have more than 1.1 million visitors every year. We feel the situation is so critical that the next 30 years will be crucial for mankind and the world.
"We all need to change our way of thinking and think more about the environment and what we are doing to it. It is all about changing people's views. We feel we have a duty to make a difference. It's all very serious stuff. Eden is very serious, but it's in a rock and roll image."
