As divisions held back emissions-cutting talks in Bonn, where countries gathered for the mid-year UN climate negotiations, Brazil’s environment minister Marina Silva put on the table an idea for a way forward: a roadmap to end the use of fossil fuels, the headline promise of the Dubai deal from 2023.

In response to a question from Climate Home during a press briefing on the sidelines of London Climate Action Week on Thursday, Silva said this year’s climate summit in Belém could result in a roadmap setting out what a “planned and just transition to end fossil fuels” should look like. 

“Perhaps we can come out of COP30 with a mandated group that can trace the roadmap for this transition,” she added, speaking to journalists in the lavish residence of Brazil’s ambassador to the UK. 

In Bonn, countries have been discussing for two weeks how to take forward the commitments agreed as part of Dubai’s Global Stocktake, including the pledge to transition away from fossil fuels in energy systems, with little progress on a way forward at COP30 later in November.

As countries have a deadline to present new national climate plans by September this year, the “UAE dialogue on implementing the Global Stocktake outcomes” is expected to inform new climate policies and signal steps to meet the Paris Agreement goal of limiting warming “well below” 2C. But negotiations broke down at COP29, and have barely inched forward at Bonn this year.

Jennifer Morgan, an architect of the landmark Dubai deal and until recently Germany’s climate envoy, told an event at London Climate Action Week that the breakthrough at COP28 is now “at risk” unless delivery on its commitments is speeded up.

Ever since COP28, governments have repeatedly failed to make explicit mentions of their promise of transitioning away from fossil fuels. At last year’s biodiversity COP in Colombia, this was left out of the final agreement despite a push from vulnerable countries, and at COP29 Saudi Ar
