The annual June climate talks in Bonn are taking place this year against the backdrop of an oil and gas supply crisis tied to the Iran war and deadly heatwaves in Europe, India and the Middle East. Can they produce anything substantial to ease the squeeze on economies and communities around the world? Watchers of the negotiations say the UN climate process is under pressure to prove its worth at a time when climate action and clean energy offer an increasingly attractive alternative to the global economic and political instability brought by fossil fuel dependency. Kaysie Brown, associate director of climate diplomacy and geopolitics at think-tank E3G, said the June 8-18 meetings ‘must show that the multilateral system can make a durable and politically resilient shift to support delivery [of climate action] at scale’. She added that it ‘will act as a key health check for the climate regime at a time of a rapidly shifting global order’.

Bonn will also see the launch of dialogues on trade and climate change, on how to implement what was promised in the first stocktake of national climate plans in 2023, and on ways to shift global finance flows to support a low-carbon and climate-resilient world. Climate Home News doesn’t have a crystal ball, but we have done our homework. Here’s what experts expect to top the agenda at the World Conference Center by the River Rhine: COP31 priorities Bonn is where we will get a sense of what the joint COP31 hosts – Türkiye and Australia – want from their presidency. Signs are that they will push for a global goal on the share of final energy consumption that will come from electricity, which may be based on a target proposed by the International Renewable Energy Agency of 35% by 2035.

Türkiye has stressed reducing emissions from landfills as a priority for the ‘Action Agenda’ strand of COP31, which encompasses government and business initiatives outside the formal discussions. Türkiye will lead on the Action Agenda, while Australia handles the negotiations. Just transition mechanism The Bonn negotiations are tasked with producing a draft decision on how to set up a new just transition mechanism that can facilitate a fair and orderly shift from a high-carbon world to a greener future. This decision will be forwarded for approval by countries at COP31. Governments agreed at COP30 in Brazil to set up what civil society has dubbed the ‘Belém-Antalya Mechanism’ (BAM) but the details have yet to be worked out. Climate Action Network International, which has advocated strongly for the global mechanism, said it should be designed to provide decent jobs, social protection, public investment, energy access and support for affected workers and communities. How Belém launched the Just Transition mechanism ‘If governments move decisively, the [BAM] could become one of the most significant developments in the climate regime since the Paris Agreement – helping connect climate action with economic transformation and tangible improvements in people’s daily lives,’ the coalition of hundreds of green groups said in a statement ahead of Bonn. Let’s talk trade At COP30, after two years of trying, emerging economies finally got the overlap between trade and climate policy onto the UN climate talks agenda. Governments agreed to hold dialogues on trade at the June Bonn talks in 2026, 2027 and 2028 before a summary of these dialogues is presented at a ‘high-level event’ in 2028. What aspects of trade are to be discussed at the first such dialogue on Saturday June 13 is undecided. Developing-country heavyweights like China and India will likely be keen to criticise the European Union’s new carbon border adjustment mechanism, which they regard as protectionist and burdensome for their exporters. Representatives of the World Trade Organization and other trade bodies will make presentations, which governments and civil society will be allowed to comment upon. Brazil’s call for COP trade forum gets lukewarm response On Sunday June 14, a separate meeting of the fledgling Integrated Forum on Climate Change and Trade – an initiative launched by the Brazilian COP30 Presidency – will take place in a grand hilltop hotel overlooking Bonn and the Rhine. The meeting is not part of the official UN climate process or the official Bonn talks and will be more informal than the previous day’s dialogue. Topics that will be discussed are trade and climate adaptation, how to create a level playing field for low-carbon products, how to trade particularly polluting products and how to bridge climate and trade tools. An expert panel chaired by South Africa’s Faizel Ismail and New Zealand’s Jo Tyndall has been appointed to advise the forum. Aligning on adaptation At COP30, talks on finalising a list of indicators to measure progress on adapting to climate change ended in recriminations, with several Latin American governments complaining that the decision was adopted by the Brazilian presidency without their consent. The indicators, which were developed by experts in a two-year process, were stripped down by the Brazilians on the last night of COP30 and presented to governments at the last minute as a done deal. New data shows rich nations likely missed 2025 goal to double adaptation finance Several governments and some of the technical experts have argued that many of the adopted indicators are unworkable, as they lack definitions or explanations of how they will be measured. Many indicators for important areas – like poverty reduction, ecosystems, infrastructure and food production – are missing or inadequate, they say. Government negotiators and experts now have two years to fix the mess, through a ‘policy alignment process’ due to end at COP32 in Ethiopia. At the Bonn talks, governments will try to agree on who will make up a new taskforce of experts to help countries put the indicators into practice and how it will operate. Mission to 1.5 and Global Implementation Accelerator After pressure from small island nations, governments at COP30 agreed to set up the Belém Mission to 1.5 and the Global Implementation Accelerator (GIA) to speed up the implementation of countries’ emissions-cutting and adaptation plans. For the Mission to 1.5, several past and current COP presidencies are drawing up a report – scheduled to be published before COP31 – which will identify several especially impactful solutions to climate change. On June 12 in Bonn, governments and civil society will weigh in on what they want included. Also in Bonn, governments will input into the GIA. The Brazilian COP30 Presidency’s vision is that it should drive forward the strongest climate solutions. According to COP30 CEO Ana Toni, an independent panel of experts will pre-select 10-15 solutions and a council will narrow this down to three to five each year which the GIA would then aim to speed up. The GIA’s ‘added value is that it will focus exclusively on solutions with the potential to scale and generate cascading effects through high-impact exponential technologies’, she said last month.

(Heirloom Carbon/Handout via REUTERS) Whether Mission to 1.5 and the GIA will identify the same shortlist of solutions – and how they work together – is unclear. But the GIA could become a permanent body working on the real-world ‘Action Agenda’ of COPs. Ruenna Haynes is the deputy lead negotiator for the small islands group (AOSIS) which pushed for these two initiatives, but she is now worried about what the COP presidencies might make of them. She told a recent briefing, ‘the last thing we want to do is to set up a process that is nothing more than a talking shop that doesn’t deliver and doesn’t go anywhere’. To avoid that, the reports of the GIA and Mission 1.5 must be linked to the wider UN climate talks process and at least discussed by governments, she emphasised. Finance roadmap and dialogue COP30 left a bitter taste regarding what was expected to be one of its main outcomes: progress on how to increase climate finance through the ‘Baku to Belém Roadmap to $1.3 trillion’. The initiative, included in the new finance goal agreed in Baku – the NCQG – was an effort to top up the 2035 target of $300 billion a year in public finance which fell short of what developing countries wanted and an independent panel of experts estimated would be needed. The high expectations surrounding this roadmap began to fade during 2025 as the process lacked transparency, clarity, participation and ambition. The result was a report abundant in general recommendations of actions to be taken but lacking clear commitments. Most of the suggestions mentioned are targeted at institutions outside the UN climate process, such as multilateral development banks. The COP30 decision merely ‘took note of’ that report. So was it the end of the road for this particular roadmap? Not yet. From Baku to Belém and beyond: How we turn a climate finance roadmap into reality In Bonn, an ‘implementation’ meeting will be held to ‘listen to the Parties and observers on the updated work being carried out,’ as a member of the COP30 Presidency team told Climate Home News. The challenge is how to ensure the roadmap doesn’t remain fine words in a document and is put into practice. It will also serve either as a good or bad example for the other two voluntary roadmaps (on deforestation and fossil fuels) that the Brazilian presidency is putting together ahead of COP31. Also in Bonn, the Veredas Dialogue will address the opportunities and obstacles to implementing Article 2.1.c of the Paris Agreement – on making finance flows consistent with low-carbon development – and its complementarity with Article 9 on the responsibility of developed countries to provide financial resources. The limitations of the Baku to Belém Roadmap could shift the divisions between developed and developing nations to this dialogue, especially considering that 2026 is the first year for mobilising finance under the NCQG. More roadmaps on fossil fuels and forests At COP30, a group of 80 countries led a failed push to kickstart a process for a global roadmap to guide the transition away from fossil fuels (TAFF). As an alternative, the Brazilian presidency proposed to draft two voluntary roadmaps: one on phasing out fossil fuels and another to end deforestation by 2030, both commitments endorsed by all countries in the COP28 deal. In the lead-up to Bonn and after months of consultations with countries, Brazil presented an outline for the forest roadmap – which will invite countries to submit their own voluntary national roadmaps to halt forest loss. It will also include a menu of options to bridge the $216-billion forest funding gap. One of the key initiatives to achieve this is the new rainforest fund, the Tropical Forest Forever Facility (TFFF), which is still rallying investors for seed funding. Brazil convened an investor meeting in Rotterdam last week, with participation from over 50 financial institutions – including BlackRock, Bank of America and Barclays – and 30 government representatives. COP30 rainforest fund unlikely to make first payments until 2028 While not on the formal negotiating agenda In Bonn, Brazil will continue consultations on the forest roadmap at an event with governments on June 8. The final document is expected to be published later in September. As for the TAFF roadmap, Brazil will hold an open event on June 12 after receiving suggestions from 120 countries. It is expected to be informed by the first global fossil fuel phase-out summit held in Santa Marta in April. COP30 advisor Flávia Bellaguarda told an online briefing that the informal sessions in Bonn are meant to open a ‘space for dialogue’ on both roadmaps, and that the more countries engage, the more international relevance the process gains. ‘We managed to get the elephant into the room. Now, it needs to stay there. For that, we need to give him plenty of food so he can’t fit through the door and leave. We achieve that with dialogue and creating space for genuine exchange,’ the Brazilian advisor said. The post What to expect from the Bonn climate talks appeared first on Climate Home News.
