Costa Rican Ambassador Alvaro Cedeno Molinari says his mission here is to deliver his country's message on green growth and renewable energy — and to develop what he describes as a green growth agenda between his country and Japan.

"My agenda is not a technical one. I'm not a biologist, I'm not an engineer. I'm simply enthusiastic about green growth and climate change, renewable energy, biotechnology, and eco-tourism," Molinari said — an agenda he says his country has been pursuing for decades.

According to Molinari, renewable energy was initially developed in Costa Rica in 1955 as an opportunity to generate electricity from the abundant hydropower sources provided by the country's extensive rivers, lakes and waterfalls.
