AOSIS and the LDCs

The strongest advocates for the 350 ppm target have been those that make up the Least Developed Countries (LDCs) and Association of Small Island States (AOSIS). These groups first officially endorsed 350 at the UN Climate Meetings in Poznan, Poland, and reiterated their support at subsequent meetings in Bonn, Germany and Bangkok, Thailand. 

AOSIS (39 countries):

Latin America (8 Countries)

A number of Latin American countries have also endorsed the 350 target as the 350 movement grows across the region.  On April 9, at one of the meetings in Bonn, Argentina endorsed the target on behalf of 14 Latin American countries:

“Argentina speaking on behalf of 14 countries in Latin America and the Caribbean, said that it was critical that emissions of developed countries be stabilized at 350 ppm by reducing at least 45% by 2020, and at least 95% by 2050 compared to 1990 levels.”

Non-AOSIS or LDC Countries in that list include: Argentina, Chile, Colombia, Costa Rica, Guatemala, Ecuador, El Salvador, Panama, Peru. Since that point,  Ecuador has rescinded its support for the target. At the recent UN inter-sessional climate meetings in Bangkok, Costa Rica, Panama, and Guatemala reiterated their support.

The Climate Vulnerable Forum (3 Countries)

This November, the Maldives hosted the Climate Vulnerable Forum for the V-11, eleven of the most vulnerable countries in the world, to discuss their joint approach to the climate crisis. At the end of the summit, the assembled countries signed a declaration calling for 350 ppm. Of the eleven countries assembled, Ghana, Kenya and Vietnam were new 350 ppm supporters.

COP 15 in Copenhagen (13 additional countries) 


During the COP15, 350.org is continuing to work with hundreds of organizations and millions of citizens to build political support for the solution that science demands: an international climate treaty that reduces carbon dioxide in our atmosphere below 350 parts per million. Since the opening of session, the 350 target and the equivalent 1.5 degrees C has gained a great amount of momentum. The following new countries have now signed onto the 350 ppm / 1.5 C target: Botswana, Cameroon, Egypt, Gabon, Ghana, Guyana, Honduras, Kenya, Namibia, Nicaragua, Pakistan, Sri Lanka, and Malaysia.

Total: 112 Countries

“A clear majority of nations at this conference have now come out in favor of a 350 target,” said Bill McKibben, founder of 350.org, the international campaign which has been building support around the world and inside the talks for a 350ppm target. “These 112 countries show great courage--the kind of courage that comes when you realize your back is genuinely against the wall.”
