COP15 Site 
The official Web site  for the 15th Conference of Parties (COP15) to the UN Framework Convention on Climate Change is run by the Danish government, which is hosting the talks. Surprisingly, it is loaded with actual news and useful information. COP15 on Twitter .
UNFCCC Site 
The Web site of the UN Framework Convention on Climate Change,  the overarching international climate agreement adopted after the Rio conference of 1992. Ratified by 192 nations, it took effect in 1994. It did not set binding emission limits or deadlines, but set up the mechanisms for ongoing negotiations. Go here for legal and institutional background.
The United Nations Environment Programme is the arm of the UN that handles most environmental matters, and it fosters the UNFCCC. This UNEP site  is a good place to find information on how climate change links with other aspects of the environment.
IPCC Reports 
The Intergovernmental Panel on Climate Change is the authoritative scientific body when it comes to climate change — compiling the work  of hundreds of scientists publishing peer-reviewed research on all aspects of the subjects.

If you are going to Copenhagen, whether as a freelancer or on assignment, this SEJ clearinghouse  may help you connect with additional stringer assignments — or help media outlets looking for stringers find you.
Climate Change Media Partnership  offers expert interviews  and other help for journalists covering the Copenhagen talks. CCMP is a joint effort of Internews,  Panos , and the International Institute for Environment and Development. 
Fresh Air Center 
Not JUST for journalists, actually. But it could serve as a center of operations for the many legitimate media likely to be denied COP15 credentials. Run by the activist group tcktcktck, the Fresh Air Center  will maintain twin facilities, one inside the security perimeter and one outside. They describe it as a "rapid response digital media hub in Copenhagen for top global bloggers and digital campaigners."

NGOs: Non-Governmental Organizations
The Copenhagen Climate Council  is a collaboration of business leaders, scientists, and policy-makers, founded by the independent think tank Monday Morning. It promotes dialogue between government and business in search of practical solutions.
The Climate Summit for Mayors  will meet December 14-17, 2009, in Copenhagen. It emphasizes action by cities.
The Climate Action Network  (CAN) is one of the largest and most important coalitions of environmentalist groups organized globally around the issue of climate change. About 500 groups affiliate with CAN.
Tcktcktck  is as much a brand as an organization. It goes beyond the traditional environmental groups to include faith-based groups, youth groups, trade unions, and individuals — and uses an innovative "open" organizing model that allows collaboraters to synergize simply by adopting the brand.
WWF  (formerly known as Worldwide Fund for Nature) is one of the largest and richest environmental groups focused on the climate issue.
Greenpeace  is one of the key international environmental groups focused on climate. It is actually a collection of national Greenpeace groups. They have a penchant for publicity and relate well to media.
WRI is really a think tank rather than an environmental group. Centrist, science-based, non-ideological, and non-partisan, they are good at setting hot issues like climate in a broader perspective of human needs.
Following the Talks from Home
The Daily Climate 
TDC  is a nicely packaged news aggregation by the folks who brought you Environmental Health News — with some original reporting. It will be one good place to get a sweeping view of all the coverage from general media. It comes out daily in the morning — but prepare for the Copenhagen-US time lag. Free online.
This very high-quality news service is subscription-only. But you can see headlines and story capsules from outside the paywall. You might even try getting a free trial subscription for the duration of COP15. ClimateWire  is written in plain English for an audience of professionals. With some time-lag, some ClimateWire articles are republished on this page  of The New York Times.
ENB  has been covering the full range of United Nations environmental negotiations for decades. It is done under auspices of the International Institute for Sustainable Development. The reporting is thorough, objective, and professional — but tends to go deeply into technical and diplomatic detail. Free online.
As a global news agency focused especially on the business fallout of international issues, Reuters  has been covering the climate negotiations more heavily than most other news organizations. They have a substantial and far-flung team of correspondents writing about climate. Almost all of this content is free online. The best places to find it are here  and here .
SciDev.Net's developing world reporters are blogging live from the climate negotiations, led by T.V. Padma, the group's South Asia Regional Coordinator.
AFP  covers the climate negotiations heavily and well. And not through the provincial blinders of the US. Most of their climate coverage is available free online on the TerraDaily  site, along with lots of other environmental news, some of it from non-AFP sources.
The National Nexus
The State Department also has a special Web page devoted to COP15 . That site includes a Press Room  which will offer releases and briefing schedules. There is also something called the U.S. Center,  an actual physical space at the Bella Conference Center in Copenhagen, which will include information displays and meeting space.
Todd Stern's Facebook Page  (Seriously!)

Group of 77 (G77) 
The G77 is an intergovernmental alliance of developing nations formed within the context of the United Nations in 1964, long before the climate issue was on the radar. Today, it also functions as an effective voice for expressing the shared interests of developing nations on climate.
Some small island nations, like the Maldives, Tuvalu, or Vanuatu will be partly or wholly submerged by the sea-level rise that will accompany global warming. All of the 40-plus states taking part in AOSIS feel a special urgency in slowing climate change because of the greater impacts it will have on them.
Annex I States (Industrialized Countries)
Now the biggest carbon dioxide emitter in the world, China is key to any effective post-Kyoto climate agreement.
This coalition consists of about 15 developing nations with significant amounts of tropical rainforest. Such nations might benefit from the sale of carbon offsets.
Organization of Petroleum Exporting Countries  (OPEC)
OPEC and other oil-exporting nations have tended to oppose efforts to reduce the growth of consumption of petroleum fuels.
