"There is no reason that some developed countries don't fulfill their commitment" to reducing greenhouse gases, said Kirchner while speaking at a U.N. session on climate change in Buenos Aires.
The Argentine president's remarks were thought to be directed at the United States, which refuses to sign the environment-protecting Kyoto Protocol.
Set to go into effect in February 2005, the protocol requires signatories to reduce greenhouse gas emission to 1990 levels by the year 2012.
The United States -- the world's largest emitter of greenhouse gases -- has refused to sign the protocol saying it would unfairly hamper U.S. industry.
