'Major polluters face mounting pressure': UN climate summit prevents utter breakdown with last-ditch deal.

As dawn crept over the Amazonian city of Belém on Saturday morning, delegates remained confined in a windowless conference room, unaware whether it was day or night. They had been 12 hours in difficult discussions, with scores ministers representing various coalitions of countries including the poorest nations to the wealthiest economies.

Patience wore thin, the air stifling as exhausted delegates confronted the grim reality: there would not be a comprehensive agreement in Brazil. The international climate negotiations teetered on the brink of complete breakdown.

The central impasse: Fossil fuels

Research has demonstrated for more than a century, the carbon dioxide produced by consuming fossil fuels is heating up our planet to critical levels.

Yet, during nearly three decades of yearly climate meetings, the urgent need to stop fossil fuel use has been mentioned only once – in a agreement made two years ago at previous UN climate talks to "move beyond fossil fuels". Delegates from the Middle Eastern nations, Russia, and a few other countries were determined this would not occur another time.

Increasing pressure for change

Simultaneously, a growing number of countries were just as committed that progress on this issue was crucially important. They had formulated a proposal that was attracting growing support and made it apparent they were willing to hold firm.

Emerging economies strongly sought to advance on securing economic resources to help them address the increasingly severe impacts of climate disasters.

Turning point

In the pre-dawn period of Saturday, some delegates were willing to walk out and force a collapse. "We were close for us," stated one national delegate. "I considered to walk away."

The breakthrough happened through discussions with Saudi Arabia. Near 6am, principal delegates separated from the main group to hold a closed-door meeting with the lead Saudi negotiator. They urged wording that would obliquely recognise the global commitment to "shift from fossil fuels" made two years earlier in Dubai.

Surprising consensus

Rather than explicitly mentioning fossil fuels, the text would refer to "the previous commitment". Upon deliberation, the Saudi delegation unexpectedly agreed to the wording.

Participants expressed relief. Applause rang out. The agreement was done.

With what became known as the "Amazon accord", the world took another small step towards the phaseout of fossil fuels – a uncertain, inadequate step that will barely interrupt the climate's steady march towards crisis. But nevertheless a significant departure from complete stagnation.

Key elements of the agreement

• In addition to the oblique commitment in the formal agreement, countries will commence creating a roadmap to phase out fossil fuels
• This will be mostly a non-binding program led by Brazil that will report back next year
• Addressing the required reductions in greenhouse gas emissions to not exceed the 1.5C limit was similarly postponed to next year
• Developing countries secured a tripling to $120bn of regular financial support to help them cope with the impacts of environmental crises
• This funding will not be completely provided until 2035
• Workers will benefit from a "fair adjustment program" to help people working in high-carbon industries transition to the renewable industry

Varied responses

While our planet teeters on the brink of climate "critical thresholds" that could devastate environments and force whole regions into crisis, the agreement was insufficient as the "giant leap" needed.

"Negotiators delivered some baby steps in the right direction, but considering the severity of the climate crisis, it has not met the occasion," cautioned one climate expert.

This flawed deal might have been the maximum achievable, given the geopolitical headwinds – including a US president who shunned the talks and remains aligned with oil and coal, the growing influence of nationalist politics, ongoing conflicts in different locations, intolerable levels of inequality, and global economic instability.

"Major polluters – the energy conglomerates – were at last in the focus at Cop30," notes one climate activist. "This represents progress on that. The platform is available. Now we must convert it to a actual pathway to a more secure planet."

Deep fissures revealed

While nations were able to welcome the official adoption of the deal, Cop30 also highlighted significant divisions in the sole international mechanism for tackling the climate crisis.

"International summits are agreement-dependent, and in a era of geopolitical divides, unanimity is progressively challenging to reach," stated one global leader. "It would be dishonest to claim that these talks has achieved complete success that is needed. The difference between our current position and what research requires remains alarmingly large."

Should the world is to prevent the worst ravages of climate collapse, the international negotiations alone will not be nearly enough.
