There are so many issues on the table at the Copenhagen U.N. climate conference that politicians from all the major players have already declared there is no hope of reaching a binding legal agreement. But progress is still possible. Participants speak of reaching a "political agreement." Exactly what that would be remains undefined, but it would represent some form of commitment to address global warming that goes beyond mere rhetoric — yet falls short of a legally binding treaty.

The two-week formal negotiations with representatives from more than 190 nations started Monday, with the ultimate goal of setting up a mechanism to reduce global greenhouse gases. If the nations of the world don't limit carbon emissions, global temperatures could rise by 5 to 11 degrees Fahrenheit by the end of the century. Sea-level change is highly uncertain, but it could rise from 7 inches to as much as 6 feet.

More than 110 world leaders have said they plan to attend the conference — that's unprecedented for climate talks. The talks kick into high gear the second week, with President Obama flying in for the closing summit.

Potential Treaty Scenarios

Negotiators hope to agree at least to the shape of a future treaty, setting the stage for talks at a follow-up conference in 2010.

Possibilities include:

Targets And Timetables: In 1997, these same nations met in Kyoto, Japan, to negotiate a climate deal. In it, the rich nations of the world jointly negotiated targets for reducing emissions of carbon dioxide and five other greenhouse gases, under a certain timetable.

The Players

The country blocs are not monolithic, but many of the issues break down along these lines:

Industrialized World: This includes the United States, Europe, Canada, Japan, Australia and the like. Countries in this bloc — with the exception of the United States — are bound by the Kyoto Protocol, which is the current climate treaty. These countries are also responsible for most of the excess carbon dioxide in the atmosphere, and they have acknowledged that they have an extra responsibility, due to that fact and their wealth, to take the strongest actions. This is not a formal negotiating bloc, but these nations often share a common view about the issues.

G77 And China: A group of about 130 developing nations forms another major bargaining bloc. These countries have no obligations under the current treaty, and they intend to keep it that way as negotiations continue. However, the major industrializing countries, which include China, India, Mexico, South Korea, South Africa and Brazil, are under pressure to make binding commitments.

Small Island States: This group of 43 nations is concerned that their very existence is in question as a result of rising sea levels. They're part of the G77.

Least Developed Countries: These 48 countries are the poorest of the poor in the world. They seek aid so they can develop using clean sources of energy, and money to help them adapt to a changing climate.

Others: OPEC meets as a bloc; and there's another alliance that includes Mexico, South Korea and Switzerland. The European Union acts as a single entity. The U.S. is also a member of the "Umbrella Group," which includes Australia, Canada, Iceland, Japan, New Zealand, Norway, the Russian Federation and Ukraine.

In The Hallways: Negotiations like this draw a large crowd of journalists, environmental activists, legislators (including U.S. congressmen and senators), lobbyists, scientists and academics. They prowl the halls, attend briefings, receptions and numerous side events. — Richard Harris

The rest of the world had no obligations. The Kyoto protocol is still in force, and contrary to what is often said about it, it does not expire in 2012. However, after that date, nations have no further emissions-reduction commitments. The United States signed the Kyoto pact, but the U.S. Senate never ratified it, so the U.S. is not party to this treaty.

That's one reason it's not very effective. Europe, the United States, Japan, Australia and Canada would just as soon drop the Kyoto Protocol and incorporate parts of it that they like into a new agreement. The developing world — which enjoyed having no obligations under this treaty — is fighting hard to keep that sweet deal. Killing Kyoto will be a hot topic in Copenhagen.

Kyoto Plus: One option in Copenhagen is to extend the Kyoto Protocol and to have a second, parallel agreement that would include the United States. (The United States has made it clear it won't join Kyoto, because it gives a free ride to China and other economic rivals.) The question, then, is what a legally binding deal that involves the U.S. would look like. In fact, the talks in Copenhagen are arranged in two parallel tracks: one dealing with the Kyoto Protocol, and a second called the Ad Hoc Working Group, which is trying to craft a parallel or replacement deal.

Pledge And Review: The United States favors an approach that marks a real departure from the Kyoto structure. Instead of jointly negotiating emissions-reduction targets and timetables for achieving them, the U.S. suggests that each nation bring to the table a pledge of what it intends to do to address climate change. For example, Obama has tentatively pledged to reduce U.S. greenhouse gas emissions by about 17 percent (relative to 2005 levels) by the year 2020. That's what the Waxman-Markey bill that passed the House aims to accomplish. Europe, meanwhile, seems prepared to reduce its emissions by 20 percent (relative to 1990 levels), which represents a deeper cut — or even 30 percent if other nations pledge to do enough.

Pledge And Review, DIY: China and other major developing countries have also stepped forward with pledges to control their emissions. These pledges are domestic plans that in some cases have legal force within the nations involved. But so far developing countries have steadfastly refused to make them legally binding in an international climate deal. The United States has made it abundantly clear that it will not accept a deal that's not legally binding internationally. This deadlock may not be resolved in Copenhagen, which means nations may leave without a clear idea of what shape a climate treaty would take.

Whatever form a treaty takes, nations will need to put something on the table to show they are serious about addressing climate change — from agreeing to emissions-reduction targets to funding clean energy efforts in poorer nations.

Emission Targets

Other Hot-Button Issues

Deforestation: About 12 to 20 percent of global warming comes from chopping down forests and clearing land, which releases carbon dioxide into the atmosphere. That makes a reduction in deforestation and forest degradation a major climate talks objective. But how to do that? Should developing nations be paid not to chop down their forests? If so, can rich nations claim credit toward reducing their emissions — how do you avoid counting forest protection twice?

If developing nations accept some obligations under the new climate treaty, they may face a tough choice of claiming forest re-growth as a local accomplishment, or they may want to take money from a rich nation, which is funding forest restoration to reach its own climate goals.

Sharing Technology: Rapidly developing nations like China might not want cash, but they say they do want access to clean-energy technologies. How could an international climate deal end up sharing technologies, considering that most advanced technologies are covered with numerous patents? The problem becomes how do you honor those patents if the technology is essentially given away?

Drawing Lines: The developing world comes to Copenhagen as a monolithic bloc of some 130 nations. But there's a huge difference between the rapidly developing nations, such as China, South Korea, India and Mexico, versus the rest of the developing world. Somewhere a line needs to be drawn. Nations above that line would be expected to commit to some actions. Nations at the bottom of the list not only would get a free pass but also would get extra aid to help them develop clean energy sources and to adapt to drought, sea-level rise and other consequences of climate change.

Some countries have already put their numbers on the table and may not actually negotiate them in Copenhagen. For example, Obama has tentatively pledged to reduce U.S. greenhouse gas emissions by about 17 percent (relative to 2005 levels) by the year 2020. Europe, meanwhile, seems prepared to make a bigger cut, reducing its emissions by 20 percent (relative to 1990 levels).

China has a voluntary target to make its economy produce less carbon dioxide per unit of gross domestic product. That makes the economy more efficient, but because China's GDP is expected to grow rapidly, emissions will continue to grow under this scenario, and China is already the world's largest emitter. These emissions targets all fall far short of what scientists say is needed to stabilize the global atmosphere. They represent political and economic decisions. So expect to hear angry words about these goals, especially from the world's poorest and most vulnerable nations.

Money For Developing Countries

The World Bank projects that developing nations will need $400 billion per year to help them develop clean energy technologies rather than burning cheap coal, which is the source of a large part of carbon dioxide emissions. These nations would need another $150 billion per year to help them adapt to a planet that is already heating up. Developing nations are demanding that much money — or even more — from the rich nations of the world, which after all are responsible for most of the greenhouse gases now in the atmosphere. But that's far too much money for countries to pony up as foreign aid. So, questions on the Copenhagen table:

— How much money will be available?

— Where will money come from? One idea is to make carbon a commodity that can be traded on international markets, and to tax each trade to build a fund for the developing world. That's highly contentious and may violate a U.S. prohibition against international taxes.

— Where will the money go? To the World Bank? The United Nations? Some new fund?

— Who will get to spend it? Will it go to sometimes questionable governments in the developing world? To specific projects? Nongovernmental organizations?

Keeping The Treaty Honest

If the nations of the world can agree on a framework for a climate, they'll need a set of rules to measure and define success. There is a daunting list of unresolved issues in this area. How will carbon emissions be measured? Who will measure economic growth, which is factored into a number of national pledges? How will the wealthy nations verify that money they give to the developing world is being spent appropriately? How will nations verify that countries are complying with their stated targets? Will there be any consequence for nations that fail to reach their emissions targets? For example, will countries impose tariffs on goods from countries that aren't in compliance with a deal — sparking possible trade wars? Or will enforcement be simply to "name and shame" the nations that fall short?

Defining Success

Dutch diplomat Yvo de Boer, the United Nations official who is managing the talks, says short of a treaty, the conference will be a success in his view if delegates agree on the following:

— The rich nations of the world should pledge to reduce their emissions by a reasonable amount and set a timeline for achieving those goals.

— Rapidly industrializing nations, such as China and India, pledge to take measures to address climate change, even though those will likely fall short of actually reducing their overall emissions.

— Developed nations put forth a substantial sum of money that can be distributed immediately to the world's poorest countries so they can start adapting to a changing climate.

— Nations should start to figure out a long-term mechanism for providing larger amounts of financial support to developing nations so they can undertake climate-friendly activities such as restoring forests and developing clean sources of energy.

But like a lot of things surrounding this conference, there's no agreement on what success at Copenhagen will look like.
