High levels of national debt in parts of the Global South could hinder efforts to move away from fossil fuels, a new report warns, as more than 50 countries gather this week in Colombia for the First Conference on Transitioning Away from Fossil Fuels.
The report, published by the Fossil Fuel Treaty Initiative in the lead-up to the flagship conference, argues that the current debt architecture is trapping developing countries in a “feedback loop” in which fossil fuel revenues are needed to service debt, while fossil fuel expansion locks countries into borrowing even more.
The cycle, according to the report, leaves very little fiscal space for highly indebted countries to end their reliance on coal, oil and gas revenues, even when their leaders want to phase out fossil fuels. This is the case for some first-mover countries such as Colombia, which is hosting the conference in Santa Marta.
Amiera Sawas, one of the report’s authors and head of research and policy at the Fossil Fuel Treaty Initiative, said the conflict in the Middle East is making this “debt injustice and fossil fuel entrapment” even more evident.
“What we have to start understanding is that both fossil fuels and debt are actually extractions from the Global South,” Sawas told the report’s launch during the World Bank and International Monetary Fund (IMF) Spring Meetings in Washington DC this month. “Many countries are paying more in debt servicing than they are getting in climate finance.”
Since 2010, low and middle-income countries (LIMCs) have more than doubled their external debt, reaching an all-time high of $8.9 trillion two years ago. They paid about $415 billion in interest on that debt in 2024 – 2.4 times higher than a decade earlier.
At the same time, in some cases like Colombia, Egypt and Jordan, austerity measures agreed as part of IMF and World Bank loan programmes restrict governments from investing in cleaner sources of revenue like renewable energy, the report says.
Leading countries constrained by debt
Colombia – one of the countries leading the global call for a transition away from fossil fuels – is facing precisely such financial barriers to achieving its transition, said Camilo Rodríguez, another of the report’s authors and a research analyst with Oil Change International.
The country has halted all new oil and gas licences and published an energy transition plan estimating transition costs at about 7-10% of its GDP. Yet the government depends on fossil fuel revenues to service its $265-billion public debt, meaning it must find an alternative source of income to cover debt payments.
Rodríguez said debt “is the main barrier nowadays to promote the energy transition and the industrialisation of the economy”.
The South American country has only grown more dependent on fossil fuels over time, as they represented 36% of exports in 2001 and now account for about 52%. Austerity policies still in place after IMF loans have left very little room for investing in Colombia’s energy transition plan, the report says.
Other countries have shown similar patterns. Jordan – despite its staggering public debt equivalent to 90% of GDP – became one of the fastest-growing markets for wind, solar and electric vehicles in the Middle East region. From 2014 to 2021, Jordan went from less than 1% of its electricity generation coming from renewables to 26%, benefiting from the significantly cheaper costs of installing wind and solar power compared with adding fossil fuel capacity.
But Jordan’s high reliance on fossil fuel revenues created an incentive for policymakers to opt for expanding gas projects over renewables, and the country ended up suspending new licences for many solar and wind projects. In 2024, about 40% of government revenues were used to service debt.
“This is not marginal – it is central to the fiscal system. It creates what I would describe as structural fiscal addiction,” said Ali Nasrallah, a policy and research manager at the Fossil Fuel Treaty Initiative. “The state depends on revenues from consumption that is economically, environmentally and socially harmful.”

Another report by the Fossil Fuel Treaty Initiative, published in March, argues that debt entrapment in Africa also exacerbates gender injustice. Social consequences from fossil fuel extraction and use – such as displacement of communities or health harm from pollution – can have a substantial effect on local women while, at the same time, states face constraints to increasing social spending to support them.
“African women are facing disproportionate impacts of the fossil fuel industry’s long-running legacy of violence and dispossession,” the report says. “But they are also leading the resistance to it,” it adds, with women-led coalitions in places like Uganda or the Niger Delta challenging major oil and gas projects.
Policy recommendations
As governments head to Santa Marta – where “gaps in the financial and investment system” are on the agenda – the Fossil Fuel Treaty Initiative recommends building international coalitions to address debt, reforming multilateral financial institutions and increasing funding commitments from donor nations.
The proposed policies include debt cancellation as a way of creating fiscal space in the Global South, ending all international finance for fossil fuel expansion, establishing a binding mechanism on debt resolution at the UN, and advancing green industrialisation to replace fossil fuel revenues.
“To dismantle carbon lock-in and debt at source, we need to recognise collectively that the escalating debt in the Global South is actually an injustice,” said Sawas of the Fossil Fuel Treaty Initiative. “We have to name the problem and be honest with ourselves – and that’s where the recommendation of debt cancellation is so critical.”
Comment: Broken debt system must be fixed to confront future climate shocks
As part of the new climate finance goal adopted at the COP29 climate summit in Baku, governments have already agreed to “remove barriers and address dis-enablers” faced by developing countries, including “limited fiscal space” and “unsustainable debt levels”.
Building on this, any plan for a global roadmap for transitioning away from fossil fuels, such as the initiative proposed at COP30 by more than 80 governments, should address the debt crisis in the Global South, Sawas said. One alternative could be financing the rollout of renewables with more public grants rather than loans, she added.
“We need to start properly funding renewable energy and diversification,” she said. “Currently it’s almost impossible for a lot of countries in the Global South to actually make the energy transition, because there’s no support structure.”
