The tiny South Pacific island nation of Tuvalu could become the first zero-carbon country after vowing to abandon fossil fuels and generate all of its energy from renewable sources by 2020.
At threat from rising sea levels caused by global warming, the low-lying nation plans to swap imported "dirty fuel" for wind and solar power.
With no heavy industry, almost no natural resources and very low existing greenhouse gas emissions, Tuvalu could become the first country in the world to realise the zero-carbon dream
"We look forward to the day when our nation offers an example to all powered entirely by natural resources such as the sun and the wind," "said Kausea Natano, the island's public utilities and industries minister.
Tuvalu is among a cluster of countries, including the Maldives, that aim to reduce their emissions to zero over the next decade.
The United Nations and many environmentalists have said the move could inspire larger emitters like the United States and China to take bolder steps to limit their carbon footprints.
