Nov 18 (Reuters) - Russia toughened on Wednesday its goal of cutting greenhouse gas emissions, saying it would target a 25 percent reduction from 1990 levels by 2020 compared with a 10-15 percent pledge previously.

Following are the negotiating positions of the top greenhouse gas emitters before a U.N. meeting in Copenhagen in December due to agree a new global climate deal.

1) CHINA (annual emissions of greenhouse gases: 6.8 billion tonnes, 5.5 tonnes per capita)

* Emissions - President Hu Jintao promised that China would cut its carbon dioxide emissions per dollar of economic output by a "notable margin" by 2020 compared with 2005. [ID:nN22195458]. The "carbon intensity" goal is the first measurable curb on national emissions in China. Hu reiterated a promise that China would try to raise the share of non-fossil fuels in primary energy consumption to 15 percent by 2020.

* Demands - China wants developed nations to cut their greenhouse gas emissions by at least 40 percent from 1990 levels by 2020 and to promise far more aid and green technology. [ID:nL1957409]

2) UNITED STATES (6.4 billion tonnes, 21.2 tonnes per capita)

* Emissions - President Barack Obama wants to cut U.S. emissions back to 1990 levels by 2020, a 17 percent cut from 2005 levels, and to 80 percent below 1990 levels by 2050.

* Obama says he wants an accord in Copenhagen that covers all the issues and that has "immediate operational effect." [ID:nLH614547].

Legislation to cut emissions by 20 percent from 2005 levels had been approved by a Senate Committee but people few think it can become law before the Copenhagen talks. [ID:nN13212295]

* Finance - The United States says a "dramatic increase" is needed in funds to help developing nations.

* Demands - "We cannot meet this challenge unless all the largest emitters of greenhouse gas pollution act together," Obama said. [ID:nLN445414]

3) EUROPEAN UNION (5.03 billion tonnes, 10.2 tonnes per capita)

* Emissions - EU leaders agreed in December 2008 to cut emissions by 20 percent below 1990 levels by 2020 and by 30 percent if other developed nations follow suit.

* Finance - EU leaders have agreed that developing nations will need about 100 billion euros ($147 billion) a year by 2020 to help them curb emissions and adapt to changes such as floods or heatwaves. As an advance payment, they suggest 5-7 billion a year between 2010 and 2012. [ID:nBRU010064]

* Demands - The EU wants developing nations to curb the rise of their emissions by 15 to 30 percent below a trajectory of "business as usual" by 2020.

4) RUSSIA (1.7 billion tonnes, 11.9 tonnes per capita)

* Emissions - Cut greenhouse gases by 22-25 percent below 1990 levels by 2020. That means a rise from now -- emissions were 34 percent below 1990 levels in 2007. [ID:nLI176075]

5) INDIA (1.4 billion tonnes, 1.2 tonnes per capita)

* Emissions - India is prepared to quantify the amount of greenhouse gas emissions it could cut with domestic actions, but will not accept internationally binding targets, Environment Minister Jairam Ramesh said. [ID:nDEL381436]. India has said its per capita emissions will never rise to match those of developed nations.

* Demands - Like China, India wants rich nations to cut emissions by at least 40 percent by 2020. But Ramesh signalled room to compromise: "It's a negotiation. We've given a number of 40 percent but one has to be realistic." [ID:nDEL313884].

6) JAPAN (1.4 billion tonnes, 11.0 tonnes per capita)

* Emissions - Cut Japan's emissions by 25 percent below 1990 levels by 2020 if Copenhagen agrees an ambitious deal.

* Finance - Prime Minister Yukio Hatoyama told the United Nations that Tokyo would also step up aid. [ID:nT293715]

7) SOUTH KOREA (142 million tonnes, 2.9 tonnes per capita)

* Emissions - Cut emissions by 30 percent below "business as usual" levels by 2020, which is equivalent to a 4 percent cut from 2005 levels. [ID:nSEO204081]

8) BRAZIL (111 million tonnes, 0.6 tonnes per capita)

* Emissions - Will cut its emissions by between 36.1 percent and 38.9 percent from projected 2020 levels, representing a 20 percent cut below 2005 levels. [ID:nN13478151]

9) INDONESIA (100 million tonnes, 0.4 tonnes per capita)

* Emissions - Aims to cut emissions by 26 percent by 2020 below "business as usual" levels. [ID:nSP495601]

Taking CO2 from deforestation into account, Indonesia is the world's third largest emitter of greenhouse gases.
