Developing countries will need between $310bn and $365bn annually by 2035 to adapt to the changing climate – 12 times more than the public adaptation finance flows they currently receive, according to the UN Environment Programme's 2025 Adaptation Gap Report. This shortfall heightens risks for some of the communities most vulnerable to climate-related disasters and is likely to loom large in COP30 talks in Brazil set to run through November 21. According to the report, private investment could increase if supported by appropriate policies, but concessional public finance remains crucial.

Pension funds have become the world's largest source of impact capital and account for 35% of impact assets under management, according to the Global Impact Investing Network's 2025 State of the Market report. According to GIIN, energy is the most targeted sector, with 85% of impact investors based in high-income countries and most likely to invest domestically. While most investors remain satisfied with their impact portfolio performance, concerns about impact-washing, data quality and macroeconomic pressures persist. Blended finance continues to play a niche but catalytic role in underserved markets.

Japan's $1.8trn Government Pension Investment Fund, the world's largest pension fund, has begun to integrate impact investing into its strategy. The shift is aimed at tackling social challenges while stimulating economic growth. GPIF's new approach includes direct investments in infrastructure and real estate, which represents a move away from traditional reliance on external managers. Although current allocations remain modest, analysts believe the move could have wider market implications as other Japanese pension funds and asset managers follow suit.

Annual investment in electricity access across Africa must grow to $15bn, six times current levels, if the continent is to achieve universal coverage by 2035, according to a report from the International Energy Agency. The IEA says the bulk of committed capital originates from international public sources and recommends regulatory reforms, targeted subsidies and innovative financing mechanisms to attract private-sector investment and direct resources to rural and vulnerable communities.

Africa's adaptation and resilience finance market is undeveloped and offers a limited pipeline for large-scale investments, according to research by the Nordic-led Investment Mobilisation Collaboration Alliance, which leads the Adaptation Finance Window for Africa (AFWA) initiative. Fund managers surveyed in the study report persistent fundraising delays and a shortage of concessional capital. The research, conducted by Magnitude Global Finance in collaboration with the World Climate Foundation, highlights AFWA's potential to spur private investment and close resource gaps.

US-based companies have halted more than $24bn of clean energy investment so far this year, according to clean energy advocacy group E2, which tracks large-scale project announcements. It says the $11bn of new investment announced in 2025 falls well short of offsetting cancellations, which include the closure of California-based sodium-ion battery manufacturer Natron Energy and a decision by General Motors to reduce its planned electric vehicle production in the US.

The European Commission is providing €2.9bn in funding raised from the EU Emissions Trading System to 61 net zero technology projects. The projects, which cover 19 industrial sectors and which are located in 18 countries, focus on areas such as energy-intensive industries, renewable energy and storage, net zero mobility and buildings, and clean technology manufacturing. The funding will be provided via the EU Innovation Fund.

The European Union has pledged more than €1.16bn in two packages to advance Africa's energy transition and broaden electricity access. The funding, part of the Africa-EU Green Energy Initiative, will support initiatives across 17 African countries. The first package includes €545 million for projects in nine countries, including a high-voltage line in Côte d'Ivoire. The second, unveiled by European Commission president Ursula von der Leyen at the Global Gateway Forum, consists of €618 million for projects in eight additional countries.

Climate Fund Managers' Gaia Climate Loan Fund, co-founded by Japan's Mitsubishi UFJ Financial Group, FinDev Canada and the Green Climate Fund, has raised $600m toward its $1.48bn target at its first close. The fund will lend to developing countries, with at least 70% of its portfolio invested in adaptation projects and the rest for mitigation initiatives, including renewable energy. Climate Fund Managers is discussing further investment by other impact-focused investors, including insurance companies and pension funds as well as family offices.

Italian impact investment firm Maia Ventures has launched its first fund, attracting €55m in financing for investment in early-stage food and agriculture ventures addressing health, resilience and efficiency issues. The fund has already made six investments and plans to provide funding of between €500,000 and €1.5m to a total of up to 25 companies.

The European Commission has proposed dropping a formal definition of sustainable investment, removing the need for principal adverse impact disclosures by funds and introducing three product categories under its review of the Sustainable Finance Disclosure Regulation. A new article 7 category would include transition funds with at least 70% of their assets having measurable transition objectives. Article 8 funds would now be funds that integrate sustainability factors, such as assets with above-average ESG ratings. Article 9 funds would require at least 70% of their assets to be in sustainable economic activities, down from the current 100%. Removing the formal definition of sustainable investment would reduce uncertainty and embed the underlying concept in a simplified form, the Commission argues.

Updated Nationally Determined Contributions and National Transition Plans due to be submitted at the COP30 summit in Brazil will offer new investment prospects for financial institutions, according to Eric Usher, the head of the UN Environment Programme Finance Initiative. These plans will set out funding targets, regulatory frameworks and project pipelines, revealing which countries are building strong conditions for private investment in climate solutions. Private-sector climate finance reached $1trn in 2023, outpacing public-sector contributions.

Responsible financing and strong exploration regulations are needed to ensure the mineral supply chains vital to the transition to clean energy are fair and sustainable, according to a UN Environment Programme report. The report argues that sustainable finance, along with robust environmental, social and governance standards and greater transparency in the sector, will become increasingly important as demand for critical minerals such as lithium and cobalt accelerates. The authors recommend such steps as incentivising recycling, improving circularity and formalising artisanal mining operations.

EU finance ministers have drawn up reforms to boost the volume of funding that development banks can commit to climate change, plans that were to be presented at the annual meetings of the International Monetary Fund and World Bank Group in October. The EU called on the institutions' shareholder countries to support strengthening of multilateral development banks in order to deliver financing on a scale aligned with the goals of the Paris Agreement and to phase out the financing of fossil fuels, despite pushback from the US government against the focus on climate change.
