Washington (CNN) The United States is now a party of one in its stance on climate change.

Syria will join the Paris climate agreement, leaving the US as the only country in the world not signed on to the landmark climate deal.

Syrian officials announced their intention to ratify the accord at the UN Climate Change Conference (COP23) in Bonn, Germany, on Tuesday.

"I confirm that the Syrian Arab Republic supports the implementation of Paris climate change accord, in order to achieve the desired global goals and to reflect the principles of justice and shared responsibility, but in accordance with the capabilities of each of the signatories," Syria's Deputy Minister of Local Administration and Environment M. Wadah Katmawi said.

Katmawi added that developed countries, "in their capacity as the primary contributors to climate change, should live up to their legal and humanitarian responsibility" by offering technical and financial support to developing countries to help battle climate change.
