In Belém, on the sidelines of COP30, Luxembourg unveiled Rio Changemakers, a platform for connecting investors and climate projects, based on AI technology developed with the Global Landscapes Forum (GLF). The announcement marks a turning point in Luxembourg's strategy for influencing international climate finance and confirms the trajectory set by Serge Wilmes over the past year: that of an Environment Minister who is increasingly acting as a genuine Minister for Green Finance.
Rio Changemakers is part of a new Luxembourg programme called the Climate Nexus Investment Program, with a budget of €320m over five years. The stated aim is to better direct financial flows towards nature-based solutions, particularly in the countries of the South where the needs are greatest and where "less than 15% of climate and biodiversity funding actually reaches local players", the organisers pointed out.
At the ministerial round table that accompanied the launch, eleven delegations joined the initiative. Serge Wilmes outlined Luxembourg's ambition: "This roundtable marks the official launch of Rio Changemakers - a bold, inclusive and science-led initiative designed to unleash private investment in climate, biodiversity, land and communities. Powered by AI and rooted in partnership, Rio Changemakers is more than a marketplace. It's a bridge - connecting high-integrity local solutions with the capital, capacity and collaboration they need to thrive." He called for an annual monitoring mechanism to measure ambition, implementation and impact: "This will help ensure accountability, transparency and continuous learning. (...) Investing in nature is not only morally right but financially viable. Luxembourg may be small, but we are determined. For us, leadership is not about domination, but about service."
A great opportunity for the South and the North to meet"
The delegations' speeches underlined the expectations raised by this technological platform. Cabo Verde's Minister of Industry, Commerce and Energy, Alexandre Dias Monteiro, saw it as a tool for "reducing risk and giving institutions access to reliable financing". For Bangladesh's Ministry of Finance, represented by AKM Sohel, "this initiative can connect the global market and strengthen the climate resilience of vulnerable countries". Guatemala's deputy environment minister, Edwin Castellanos, welcomed "a great opportunity for the South and the North to meet". Similar support was expressed by Tunisia, Ethiopia, Switzerland, Denmark, Liechtenstein, Turkey and Brazil.
The initiative is a direct extension of the positions taken by Serge Wilmes over the last twelve months. Since taking up his post, he has stepped up his international activities to become an ambassador for an approach to climate finance structured around one principle: directing private capital towards nature-based solutions and projects that benefit local communities. This orientation was already evident at the United Nations Ocean Conference in Nice in June, where the Minister highlighted Luxembourg's commitments to the blue economy via the Blue Natural Capital Financing Facility (BNCFF) as well as cooperation with the EIB and the Global Green Growth Institute, particularly for the benefit of small island developing states.
It was also expressed through the announcement, the same month, of the commitment of €5m in the Outrigger Impact I fund via the Luxembourg-BEI Climate Finance Platform (PFCL/LCFP), a tool that mobilises the private sector by using subordinated public financing to attract investors. This fund explicitly targets the most vulnerable economies, particularly small island developing states, in sectors such as sustainable aquaculture, ecotourism or renewable energy.
At COP29 in Baku, the Minister defended an ambitious new collective climate financing target and presented Luxembourg's future €320m envelope for 2026-2030, designed to strengthen the country's action in international climate financing. At the meeting, Luxembourg also reaffirmed its support for the Global Shield against Climate Risks, an insurance and financial protection mechanism for the countries most affected by climate disasters, to which it is already contributing €5.5m.
Aligning economy and ecology, the minister's leitmotiv
These positions are accompanied by a broader desire to reposition the Luxembourg financial centre as a platform for capital directed towards climate and biodiversity solutions. The Minister stated this at the IUCN Leaders' Forum in Geneva, where he pointed out that investments in nature are considered riskier in developing countries due to a lack of institutional capacity or adequate financial structures, and called for mixed finance mechanisms capable of reducing this risk and attracting private investors. At the time, he insisted on the need to "align the economy and ecology", a leitmotif that now structures the ministry's speeches.
Rio Changemakers therefore appears to be the focal point of this strategy. The result of collaboration between Luxembourg and the GLF as part of the "Finance for Nature" platform, it aims to create a global market for climate and biodiversity solutions, with an automated matchmaking engine and technical support designed to make projects "bankable". The initiative will enter a twelve-month pilot phase before going fully live at COP31.
With this launch, Serge Wilmes is reinforcing Luxembourg's singular positioning: a small state seeking to play a disproportionate role in transforming international financial flows, by combining financial expertise, climate diplomacy and technological innovation. A line that is increasingly becoming one of the hallmarks of its policy, and which aims to make the country a key player in green finance on a global scale.
