'Fossil fuel giants finally in the crosshairs': UN climate summit prevents total failure with desperate deal.

When dawn was breaking the Amazonian city of Belém on Saturday morning, negotiators remained stuck in a windowless conference room, unaware whether it was day or night. For more than 12 hours in tense discussions, with scores ministers representing 17 groups of countries including the most vulnerable nations to the richest economies.

Frustration mounted, the air stifling as sweaty delegates acknowledged the grim reality: they were unlikely to achieve a comprehensive agreement in Brazil. The 30th UN climate conference teetered on the brink of abject failure.

The central impasse: Fossil fuels

Scientific evidence has shown for well over a century, the CO2 emissions produced by burning fossil fuels is warming our planet to alarming levels.

Nevertheless, during over three decades of yearly climate meetings, the urgent need to halt fossil fuel use has been mentioned only once – in a decision made two years ago at Cop28 to "shift from fossil fuels". Representatives from the Arab Group, Russia, and several other countries were adamant this would not happen again.

Mounting support for change

Simultaneously, a expanding group of countries were similarly resolved that advancement on this issue was crucially important. They had formulated a proposal that was gathering increasing support and made it apparent they were prepared to stand their ground.

Developing countries desperately wanted to advance on securing economic resources to help them cope with the increasingly severe impacts of climate disasters.

Breaking point

In the pre-dawn period of Saturday, some delegates were willing to walk out and cause breakdown. "It was on the edge for us," stated one energy minister. "I was prepared to walk away."

The critical development happened through negotiations with Saudi Arabia. Around 6am, senior representatives separated from the main group to hold a closed-door meeting with the head Saudi negotiator. They urged text that would subtly reference the global commitment to "shift from fossil fuels" made two years earlier in Dubai.

Unexpected agreement

Rather than explicitly referencing fossil fuels, the text would refer to "the previous commitment". After consideration, the Saudi delegation unexpectedly approved the wording.

Participants showed visible relief. Cheers erupted. The deal was completed.

With what became known as the "Brazil agreement", the world took another small step towards the gradual elimination of fossil fuels – a faltering, inadequate step that will minimally impact the climate's ongoing trajectory towards crisis. But nevertheless a important shift from absolute paralysis.

Important aspects of the agreement

• Alongside the subtle acknowledgment in the formal agreement, countries will begin work a roadmap to phase out fossil fuels
• This will be largely a optional undertaking led by Brazil that will deliver findings next year
• Addressing the required reductions in greenhouse gas emissions to not exceed the 1.5C limit was likewise deferred to next year
• Developing countries achieved a significant expansion to $120bn of annual finance to help them adapt to the impacts of extreme weather
• This sum will not be delivered in full until 2035
• Workers will benefit from a "fair adjustment program" to help people working in fossil fuel sectors shift to the sustainable sector

Differing opinions

As the world hovers near the brink of climate "critical thresholds" that could eliminate habitats and throw whole regions into disorder, the agreement was far from the "significant advancement" needed.

"The summit provided some baby steps in the correct path, but considering the magnitude of the climate crisis, it has not met the occasion," warned one environmental analyst.

This limited deal might have been the maximum achievable, given the international tensions – including a Washington administration who ignored the talks and remains committed to oil and coal, the rising tide of rightwing populism, persistent fighting in various areas, unacceptable degrees of inequality, and global economic uncertainty.

"The climate arsonists – the oil and gas companies – were finally in the focus at the climate summit," notes one policy convener. "There is no turning back on that. The opportunity is open. Now we must convert it to a genuine solution to a safer world."

Significant divisions revealed

While nations were able to welcome the formal approval of the deal, Cop30 also exposed major disagreements in the primary worldwide framework for confronting the climate crisis.

"Climate conferences are agreement-dependent, and in a era of geopolitical divides, agreement is ever harder to reach," commented one international diplomat. "We should not suggest that Cop30 has provided all that is needed. The difference between where we are and what evidence necessitates remains dangerously wide."

When the world is to avoid the worst ravages of climate crisis, the international negotiations alone will fall far short.
