More cities pledge greater green efforts

Officials and urban leaders from China and the United States approved a declaration on Wednesday that sets the course for further cooperation between two countries to fight climate change.

The Climate Leaders Declaration was the outcome of the Second China-US Climate-Smart Low-Carbon Cities Summit, during which attendees discussed strategies and practices for fighting climate change, and signed 27 working agreements and memorandums of understanding.

The two countries - the world's largest carbon dioxide emitters - have pledged to take enhanced actions to reduce carbon emissions and increase climate resilience.
