TIANJIN - Chinese NGOs and academics urged the United States to immediately beef up its domestic efforts in tackling climate change, and stop using China as its excuse for inaction on the sidelines of the UN climate meeting in Tianjin.

The US "not only failed in passing a crucial climate legislation on time meanwhile, it has been seeking to divert attention away from its own failures by pointing fingers on China," said Dale Wen, a scholar at the International Forum on Globalization, who led a report comparing the two country's policies and actions on tackling climate change.

The researchers find that, as a developing country, China's serious domestic mitigation efforts have already exceeded that of the US side, though its per-capita greenhouse gas (GHG) emissions remains only one-fourth of that in US.
