Understanding COP: Climate’s biggest event of the year

What is COP?

Formally, the COP is the decision-making platform for signatories of the UN Framework Convention on Climate Change (UNFCCC). The UNFCCC is a legally binding agreement between UN member countries, created specifically to tackle the crisis of climate change. Each year since its creation, delegations from participating countries (called Parties) have met at the COP to discuss the agreements and mechanisms by which to address climate change. 

After two weeks of negotiation, conference delegates produce text that becomes binding for UNFCCC Parties. These texts have legislated things from the commitment of industrialized nations to reduce emissions, to the direction of funding for climate action, to the upper limit of acceptable warming. 

The prominence and importance of these conference proceedings have grown with each year and each increment of warming. The conference itself has expanded to encompass climate action across multiple channels at once.

“There are actually three COPs happening in parallel,” says Woodwell Climate’s Director of International Government Relations, Dr. Matti Goldberg, who has learned the ins and outs of the conference over 15 years spent working for the UN’s Climate Change Secretariat.

The first layer is the core of the conference— the negotiations. This is the space where each participating country sends delegates to argue on their behalf. The agenda for each year’s negotiations is developed during preparatory meetings of the delegates, with planning sometimes starting two years in advance, and resulting in agendas of 50-60 interlinked issues. COPs are typically judged as successes or failures based on the strength of the resulting text from the formal negotiations. The complexity of the issues, and the negotiating tactics of different countries, tend to push final agreements well beyond the scheduled closing of the COP. 

Then there’s what Goldberg calls the “high-level COP.” This is the platform for heads of state to showcase their country’s progress on various issues. Think, speeches from the president, announcements of new coalitions, hand-shaking between ministers, or denunciations of other countries’ lack of action. Although the high-level COP can feel like superficial performance, deals between countries can help move the negotiations forward— or delay them, depending on a country’s interests.

Surrounding both the formal negotiations and closed door deals is the “third COP” — also referred to as the “Blue Zone”: a space open to scientists, NGOs, activists, and companies for hosting side events, pavilions with panel talks and presentations, forge new partnerships, hold protests, and apply pressure on negotiators. The third COP also spills out into a “Green Zone”, a space where those not badged for the official conference can organize events and contribute to the momentum of the moment.

What does an NGO do at COP?

For an organization like Woodwell Climate, the third COP is the main stage on which to contribute to the conference. 

“Our first priority is to showcase our research and its relevance to the key questions of each year’s COP,” says Goldberg.

At COP29 in Baku, Azerbaijan, Woodwell Climate will host a pavilion to showcase the organization’s work in several key areas, including climate risks and national security, accounting for growing natural emissions sources like permafrost thaw and wildfires, as well as emerging collaborations with new partner countries such as Ethiopia. The pavilion also serves as a convening place to discuss work with partners.

“The sheer scale of participation at COPs makes them critical annual opportunities to solidify existing partnerships and build new ones,” says Goldberg.

While participants of this third COP aren’t officially part of negotiations, Woodwell Climate scientists still have opportunities to participate in the more formal COP processes. Each COP hosts an “Earth Information Day” where scientists exchange data and research with country delegations to better inform decision making. At COP29, Woodwell has proposed to highlight the latest research on wildfire emissions.

Scientists also have a role to play in ensuring national emissions reductions plans are based on accurate numbers—a point that Woodwell Climate will be emphasizing both at this COP and beyond. In 2025, countries must submit their updated 5-year climate targets (called Nationally Determined Contributions or NDCs) to the UNFCCC. The adequacy of those targets depends on how much carbon can still be emitted without surpassing the agreed-upon maximum limit of warming.

“Our research on permafrost and wildfires indicates that the global carbon budget available for staying below the 1.5 degrees Celsius temperature limit might be much smaller than countries are thinking right now,” says Goldberg. “From the Woodwell perspective, it would be great to remind the international community that the numbers need to add up. We need to take into account these emissions that are not being discussed.”

Successes and failures in three decades of COP

Over his tenure with the UN Secretariat, Goldberg has witnessed both promising action and frustrating setbacks, sometimes at the same conference. 

COP15, held in Copenhagen in 2009 was one of those moments for him. Here negotiations decayed, and the weak resulting agreement failed to legally bind countries to emissions reductions.

However, legally binding targets for all countries isn’t a realistic approach in a world where sovereign nation states are concerned about energy security, Goldberg observes. “Countries will generally not agree to a regime that will force them to take on targets determined by the UN or by others.”

But Goldberg says that Copenhagen did, at least, define a new paradigm where every country would commit to doing something. Voluntarily, and perhaps not ambitiously enough, but in a year widely considered a failure, steps towards universal climate cooperation were still made.

Each successive COP built upon this new paradigm and in 2015 the conference arrived at another milestone— the Paris Agreement. This is the framework under which the world operates today, with every country creating NDCs appropriate to their size and resources, with the goal of limiting warming to 1.5 degrees C above pre-industrial levels. 

The agreement spurred more conversation around how that goal would be achieved, and in 2018 the parties adopted a rulebook for its implementation. Since then, however, Goldberg says many of the conferences have been “searching for real purpose” — some kind of action to match the ambition of the Paris Agreement. But, in Goldberg’s mind, that doesn’t necessarily indicate a failure of the process.

“You can’t have a spectacle forever,” says Goldberg. “At some point the pressure should be less on the COP itself and more on countries actually working under the Paris Agreement to get more ambitious about what they’re doing, and probably making some very painful decisions at the national level.”

Climate has the world’s attention

But of course, policy making moves slowly, both for the UN and national governments. And with each year that passes, cooperation and increased ambition becomes more urgent. In 2023, record high temperatures spurred conversations about whether the 1.5 degree limit has already been surpassed. In five years, Goldberg states, “it might be way too late even to pretend that we are under that limit.”

But Goldberg remains hopeful. Before the COPs, before 30 years of tough conversations attempting to find a way through the climate crisis, Goldberg says, the prevailing thought among political scientists was that international cooperation on this scale was a fantasy. But despite its failures, the process has persisted, inching the world towards climate action. Other international treaties have taken their lead from this process as well, hosting COPs to address issues like plastic pollution and biodiversity.

“The fact that there are so many people dedicated to solving this and to working through mutual disagreements, that people haven’t walked away, makes me hopeful,” says Goldberg. “This is possibly the hardest global policy problem there is, and it has the world’s attention. I think that’s very positive.”
