A group of conflict-affected countries is pushing at COP29 to double financial aid to more than $20 billion a year and combat the natural disaster and security crises facing their populations, a letter seen by Reuters showed.

The group is one of several pitching at the climate talks in Azerbaijan this week for funds to better prepare for the impacts of extreme weather as countries seek to agree to a new annual target on financing.

Island nations, for example, argue climate change threatens their very existence as seas rise, while rainforest nations say they need more money to protect their vast carbon sinks.

Countries mired in conflict and its aftermath say they have struggled to access private investment, as they are seen as too risky. That means UN funds are even more critical to their populations, many of whom have been displaced by war and weather.

In response, the COP29 Azerbaijan Presidency on Friday will launch a new ‘Network of Climate-vulnerable Countries’, including a number of countries that belong to the g7+, an intergovernmental group of fragile countries, which first sent the appeal.

The network aims to advocate as a group with climate finance institutions; build capacity in member states so they can absorb more finance; and create country platforms so investors can more easily find high-impact projects in which to invest, said think tank ODI Global, which helped the countries create the network.

Burundi, Chad, Iraq, Sierra Leone, Somalia, Timor-Leste and Yemen have already joined the initiative, but all 20 members of the g7+ have been invited. “My hope is it will create a real platform for the countries in need,” said Abdullahi Khalif, chief climate negotiator for Somalia on the sidelines of the Baku talks.

The move follows a letter sent by the g7+ to the United Nations, World Bank Group, International Monetary Fund and COP presidencies last month, and shared exclusively with Reuters, asking for more support.

In it, the group demanded an explicit commitment in any final deal on finance at COP29 that would double financing to help them adapt to climate change to at least a collective $20 billion per year by 2026.

While 45 of the world’s least developed countries have their own UN negotiating group, which includes some of the g7+ countries, conflict-affected states face distinct struggles, advocates said.

“A flood situation in South Sudan or Somalia creates more catastrophe than it would in any other developing country,” said Habib Mayar, g7+ deputy general secretary, who helped coordinate the letter.

A child born in South Sudan, which has been mired in war since 2013, was 38 times more likely in 2022 to be internally displaced by climate-related disasters than a European or North American child, according to Unicef data.

Yet conflict-affected countries received only $8.4bn in climate funding in 2022 about a quarter of what was needed, according to a 2024 analysis by ODI Global.

“It’s clear that climate funds aren’t doing enough to support the world’s most climate vulnerable people,” said Mauricio Vazquez, ODI Global’s head of policy for global risks and resilience, said.
