Obama Administration's refutation came after The New York Times reported that the United States was pushing for an international voluntary treaty on climate change.
"Not a word of the new climate agreement currently under discussion has been written, so it is entirely premature to say whether it will or won't require Senate approval," State Department Spokesperson Jen Psaki said.
"Our goal is to negotiate a successful and effective global climate agreement that can help address this pressing challenge. Anything that is eventually negotiated and that should go to the Senate will go to the Senate. We will continue to consult with Congress on this important issue," she said.
"We're pushing to broker the kind of an agreement that would tangibly have an impact on reducing the causes of climate change and the causes of the kinds of pollution that have such a detrimental effect on public health in this country and in communities all around the world," he said.

Obama has articulated a number of times this year the need to address the threat that climate change poses both to human health and to the US economy.
"That's why he put forward a comprehensive plan to cut carbon pollution and prepare the United States for the impacts of climate change while also leading an international effort to combat global climate change," he said.
