57 Countries Declared the Fossil Fuel Era Over. The Same Week, Oil Spiked.
What happened
The world's first international conference explicitly focused on transitioning away from fossil fuels concluded April 29 in Santa Marta, Colombia. Fifty-seven countries, representing approximately one-third of global GDP, signed a joint declaration stating the energy transition is 'past the point of no return.' The conference produced five concrete outcomes: shared roadmaps for reducing fossil fuel supply, demand-side policy frameworks, a financing dialogue, technical assistance for producer countries to diversify economically, and a formal follow-up process. The meeting was deliberately organized outside the UN climate negotiation process because petrostates had blocked any fossil fuel language at COP30 in Brazil six months earlier. The conference opened while the US-Iran naval blockade of the Strait of Hormuz entered its tenth week, producing an oil price spike that complicated the summit's messaging.
The Santa Marta declaration is the most significant formal political commitment to ending the fossil fuel era ever made, and it was made while the world's most important oil chokepoint was being blockaded by the country most responsible for attending.

The Hidden Bet
The Hormuz blockade strengthens the case for energy transition by demonstrating fossil fuel vulnerability
The immediate effect of the blockade is the opposite: it makes fossil fuels more strategically irreplaceable in the short term, empowers petrostate producers outside the strait, and creates a domestic political argument in every energy-importing country that energy security requires more supply, not less. The long-run argument for transition gets stronger; the short-run politics move against it.
Organizing outside the UNFCCC process allows the coalition to move faster
The five outcomes from Santa Marta are non-binding declarations, not treaties. The UNFCCC process is slow precisely because it requires consensus among states with opposite interests, but it also creates binding obligations. The Santa Marta coalition is faster and less inclusive, which means it produces signals without enforcement.
The 57-country coalition represents a decisive majority in global energy markets
The absent countries are doing most of the producing. Saudi Arabia, Russia, UAE, Iraq, and other OPEC members were not signatories. The countries at Santa Marta are largely consumers, not producers. Committing to reduce demand while producers continue maximizing supply does not by itself end the fossil fuel era.
The Real Disagreement
The conference produced two competing framings that cannot both be true. The first holds that the Hormuz blockade is the strongest argument for accelerating the energy transition: fossil fuel dependence is a national security catastrophe, and the way to prevent the next one is to exit fossil fuels faster. The second holds that the Hormuz blockade demonstrates that the transition cannot be fast: the world cannot replace oil in the timeframe required for energy security, which means managing fossil fuel production carefully through the transition is more important than declarations about its end. Both framings have genuine constituencies. The financing question identified at Santa Marta, how do you compensate producer countries for leaving oil in the ground, is the one that has to be answered before either framing matters. It was not answered.
What No One Is Saying
The US sent a delegation to Santa Marta despite running the Iran war, which is structurally predicated on oil price leverage and fossil fuel geopolitics. The implicit message from the US government this week was: we are blockading the world's most important oil transit chokepoint while simultaneously declaring that the transition away from oil is past the point of no return. These two positions are not being examined together in mainstream coverage. They imply either that the US does not actually intend to end the fossil fuel era on any timeline relevant to climate, or that the Iran war is itself accelerating the transition by making the cost of oil dependence visible.
Who Pays
Countries economically dependent on fossil fuel exports that signed the declaration
Over the medium term, as domestic fossil fuel industries lobby against implementation.
Colombia, which hosted the summit, is itself a significant oil producer. Signing a declaration to phase out fossil fuels without a concrete financing mechanism for the transition imposes domestic political costs without providing the revenue replacement the declaration implicitly promises.
Low-income countries that are large fossil fuel producers but not at the table
Over the next 10-20 years as demand reduction from major economies bites.
If the 57-country coalition successfully reduces global demand for fossil fuels without providing transition financing, oil-dependent developing economies face a collapsing revenue base with no replacement. The Santa Marta outcomes' technical assistance provisions are aspirational, not funded.
Climate advocates in countries represented at Santa Marta
Within the next two years, as the follow-up process either produces binding commitments or doesn't.
A non-binding declaration that fails to deliver policy change delegitimizes the climate movement in those countries by raising expectations it cannot meet. Each failed declaration makes the next one harder to build political support for.
Scenarios
The Hormuz acceleration
The blockade extends past summer and oil prices stay elevated. Major energy-importing economies accelerate clean energy investments as an explicit national security response. The Santa Marta declaration gets its financing mechanism from military and security budgets, not climate budgets.
Signal A G7 country announces emergency clean energy investment framed explicitly as Hormuz-blockade risk reduction.
Declaration without delivery
The follow-up process produces additional declarations but no binding commitments. Petrostate lobbying at COP31 dilutes the language. The Santa Marta coalition fractures as energy security pressures in member countries push governments toward supply expansion.
Signal COP31 communique avoids specific fossil fuel phase-out language despite the Santa Marta precedent.
Financing breakthrough
The EU and major development banks commit to a specific financing mechanism for producer-country transition. One or two major petrostate observers join the coalition. The Santa Marta framework becomes the de facto successor to the Paris Agreement on fossil fuels.
Signal A World Bank or EU financing commitment of more than $50 billion specifically linked to producer-country fossil fuel exit is announced before COP31.
What Would Change This
If major petrostate producers, particularly Gulf states, agreed to join the follow-up process in exchange for credible transition financing, the Santa Marta declaration would transform from a consumer-country commitment to a genuine supply-and-demand framework. Nothing at Santa Marta suggests that is imminent.
