'Fossil fuel giants finally in the crosshairs': UN climate summit prevents utter breakdown with last-ditch deal.

While dawn illuminated the Amazonian city of Belém on Saturday morning, delegates remained trapped in a windowless conference room, uncertain whether it was day or night. Having spent 12 hours in tense discussions, with scores ministers representing multiple blocs of countries including the least developed nations to the richest economies.

Patience wore thin, the air heavy as sweaty delegates confronted the sobering reality: there would not be a comprehensive agreement in Brazil. The international climate negotiations faced the brink of total collapse.

The major obstacle: Fossil fuels

As science has told us for more than a century, the greenhouse gases produced by utilizing fossil fuels is heating up our planet to alarming levels.

Nevertheless, during more than three decades of annual climate meetings, the urgent need to stop fossil fuel use has been addressed only once – in a decision made two years ago at previous UN climate talks to "shift from fossil fuels". Officials from the Gulf states, Russia, and a few other countries were resolved this would not be repeated.

Mounting support for change

Meanwhile, a expanding group of countries were just as committed that advancement on this issue was vitally needed. They had created a plan that was gathering increasing support and made it apparent they were prepared to dig in.

Less wealthy nations desperately wanted to advance on securing financial assistance to help them manage the growing impacts of extreme weather.

Turning point

During the night of Saturday, some delegates were willing to withdraw and force a collapse. "We were close for us," stated one energy minister. "I was ready to walk away."

The breakthrough happened through discussions with Saudi Arabia. Shortly after 6am, senior representatives split from the main group to hold a closed-door meeting with the chief Saudi negotiator. They encouraged language that would subtly reference the global commitment to "transition away from fossil fuels" made two years earlier in Dubai.

Unanticipated resolution

As opposed to explicitly mentioning fossil fuels, the text would refer to "the UAE consensus". After consideration, the Saudi delegation unforeseeably agreed to the wording.

The room collapsed into relief. Applause rang out. The settlement was completed.

With what became known as the "Belém political package", the world took another small step towards the phaseout of fossil fuels – a uncertain, inadequate step that will minimally impact the climate's steady march towards crisis. But nevertheless a important shift from complete stagnation.

Important aspects of the agreement

• In addition to the oblique commitment in the formal agreement, countries will start developing a plan to systematically reduce fossil fuels
• This will be largely a optional undertaking led by Brazil that will provide updates next year
• Addressing the required reductions in greenhouse gas emissions to not exceed the 1.5C limit was also put off to next year
• Developing countries obtained a threefold increase to $120bn of regular financial support to help them cope with the impacts of environmental crises
• This funding will not be fully available until 2035
• Workers will benefit from a "equitable change process" to help people working in polluting businesses move toward the sustainable sector

Mixed reactions

While our planet teeters on the brink of climate "critical thresholds" that could devastate environments and plunge whole regions into chaos, the agreement was insufficient as the "significant advancement" needed.

"Negotiators delivered some modest progress in the correct path, but considering the magnitude of the climate crisis, it has failed to rise to the occasion," warned one climate expert.

This limited deal might have been all that was possible, given the geopolitical headwinds – including a US president who shunned the talks and remains committed to oil and coal, the growing influence of nationalist politics, persistent fighting in multiple regions, unacceptable degrees of inequality, and global economic uncertainty.

"The climate arsonists – the fossil fuel giants – were ultimately in the crosshairs at these negotiations," comments one climate activist. "We have crossed a threshold on that. The political space is open. Now we must transform it into a genuine solution to a protected environment."

Significant divisions revealed

Although nations were able to celebrate the formal approval of the deal, Cop30 also highlighted major disagreements in the only global process for addressing the climate crisis.

"Climate conferences are unanimity-required, and in a period of geopolitical divides, agreement is ever harder to reach," observed one senior UN official. "We should not suggest that these talks has delivered everything that is needed. The gap between our current position and what research requires remains alarmingly large."

Should the world is to avert the gravest consequences of climate crisis, the global discussions alone will not be nearly enough.
