Following are notable quotes about U.N. climate talks in Copenhagen on Thursday, where negotiations were deadlocked with just one day left to work out a new deal to combat global warming after two years of work.
A summit of more than 120 world leaders will try to break the deadlock on who should cut greenhouse gas emissions, by how much and who should pay.
YVO DE BOER, HEAD OF THE U.N. CLIMATE CHANGE SECRETARIAT
He has likened the Dec 7-18 talks to a start/stop cable car ride to a mountaintop. Hold tight and mind the doors, the cable car is moving again, he said.
U.S. SECRETARY OF STATE HILLARY CLINTON
In the context of a strong accord, in which all major economies stand behind meaningful mitigation actions and provide full transparency as to their implementation, the United States is prepared to work with other countries towards a goal of jointly mobilising $100 billion (62 billion pounds) a year by 2020 to address the climate change needs of developing countries.
We expect this funding will come from a wide variety of sources, public and private.
On China and transparency over emissions:
It would be hard to imagine, speaking for the United States, that there could be the legal or financial commitment that I've just announced in the absence of transparency from the second biggest emitter, and now the I guess the first biggest.There has to be a willingness to move towards transparency in whatever forum we finally determine is appropriate. So if there is not even a commitment to pursue transparency that's kind of a dealbreak for us.
CHINA'S CLIMATE CHANGE AMBASSADOR YU QINGTAI
Copenhagen is too important to fail
China is not interested in becoming a party to the efforts by some people to try to blame other countries for a failure at Copenhagen.
I believe what they are trying to do is to find excuses for their own obstructive role and very unconstructive attitude in the whole process.
GERMAN CHANCELLOR ANGELA MERKEL
The news that we've been receiving is not good, she told parliament in Berlin. I must say very honestly, that the United States offer to cut (C02 emissions) by 4 percent compared to 1990 levels is not ambitious.
INDIAN ENVIRONMENT MINISTER JAIRAM RAMESH
The biggest stumbling block in my view is the desire of the part of some parties to abandon the Kyoto protocol unilaterally and I think there's been an absence of trust and I think the blame-game has begun.SWEDISH ENVIRONMENT MINISTER ANDREAS CARLGREN
We have a very serious situation.
PRESIDENT OF THE MALDIVES, MOHAMED NASHEED
I am very hopeful that we can still have an agreement. I wasn't so hopeful last night, but this morning I feel that we can still come out with an agreement tomorrow.
On U.S. President Barack Obama:
He has to raise his emissions ambitions higher, much, much higher. It really is not so proper for the United States to say that they cannot raise their ambition. If there is one country who has all the technology and all the money to green their economy the United States is of course the country. I really hope the US can raise emissions expectations much, much higher.
UGANDAN ENVIRONMENT MINISTER MARIA MUTAGAMBA
The biggest stumbling block is that we're not able to follow the normal procedure and secondly that we seem to be sidelining the Kyoto Protocol. I still have some hope that we will come around and have an agreement to the process.
JAPANESE ENVIRONMENT MINISTER SAKIHITO OZAWA SAYINGSome countries even amongst the G77 plus China are working with us and we in Japan have in consultation with some other countries that they are still the stumbling block.
RAJENDRA PACHAURI, CHAIR OF INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE:
We still have two days left and I hope that in these two days something happens to break the logjam that we have currently in the negotiations.
