The document identifies the secondary treatment stage as the highest energy consumer in wastewater treatment works, particularly in systems using activated sludge where aeration can account for 50% of process energy. It recommends benchmarking specific power consumption (SPC) and implementing interventions such as fine bubble aeration, dissolved oxygen control, and cascade aeration to reduce costs and greenhouse gas emissions. Financing options for these projects include municipal budgets, grants, concessional loans, and energy performance contracts.

The Adaptation Fund (AF), established in 2001 under the Kyoto Protocol, provides funding for climate resilience in vulnerable countries. While it offers a unique 'direct access' mechanism allowing countries to manage funds through National Implementing Entities (NIEs), the brief notes that Africa faces capacity challenges in utilizing this. Funding primarily relies on a 2% levy from the Clean Development Mechanism (CDM), which the document argues is unpredictable and potentially shifts the financial burden from developed to developing nations. Africa has received 24.9% of AF funds, but the brief highlights a lack of approved projects and insufficient funding relative to requests.

The Sierra Leone Energy Transition and Green Growth Plan outlines a pathway to 100% electrification and clean cooking by 2040. The plan emphasizes a shift from biomass and oil toward hydropower and solar PV, requiring an estimated USD 6.5 billion in capital investment by 2040 and a cumulative USD 15 billion by 2050. Key targets include deploying 745 MW of large hydropower and 932 MW of solar PV by 2040, while integrating electric mobility and green hydrogen by 2050. The transition is expected to double energy-sector jobs to 29,117 by 2050 and support national goals such as the Feed Salone strategy and Nationally Determined Contributions (NDCs).

Mali's revised NDC aims for a 40% total reduction in net GHG emissions by 2030 compared to a business-as-usual scenario. The plan covers four sectors: energy, agriculture, forestry/land-use change, and waste, with specific reduction targets for each. It emphasizes a transition to a low-carbon economy through renewable energy, sustainable agriculture, and intensive reforestation (REDD+). Adaptation is a priority, focusing on green economy resilience, water management (GIRE), and gender-sensitive policies. The total cost for mitigation is estimated at $4.344 billion, while adaptation is valued at $8 billion.

The report by Scientists for Global Responsibility (SGR) examines the American Physical Society's (APS) financial practices, noting a lack of transparency regarding $181.9 million in securities and the absence of a formal ethical investment or environmental policy. While the APS has no known fossil fuel sponsors and has committed to tackling the climate crisis, SGR expresses concern over donations from the arms trade and the inability to verify if APS investments contradict its public climate statements.

The document highlights a severe imbalance in climate finance, noting that adaptation funding reached only USD 76 billion in 2022, representing barely 5 percent of total flows. It criticizes the lack of quantitative clarity in the NCQG regarding adaptation allocations and proposes several options for setting a credible quantum and institutional home for a post-2025 adaptation finance goal.

The document identifies critical bottlenecks in Colombia's energy transition, specifically in transmission infrastructure and licensing, which cause project delays of three to six years. It argues that while capital is available, there is a shortage of bankable, large-scale projects. To bridge a projected annual investment gap of 27.7 billion COP (approximately 7.5 billion USD) in clean energy for 2026-2030, the report recommends utilizing blended finance, asset securitization, and a dedicated economic transition fund to support regions dependent on fossil fuels, where 448,000 jobs are at risk by 2035.

The document outlines the urgent need for increased financial flows to meet Paris Agreement goals, noting that global mitigation investments must increase by a factor of 36 by 2030 to limit warming to 2°C. It identifies a three-stage process for financing NDCs—planning, implementation, and monitoring—and suggests that governments utilize a mix of financial, fiscal, and policy instruments to mobilize both public and private finance. The report highlights that developing countries face significant gaps, with reported financial needs reaching $4.3 trillion, far exceeding existing pledges.

The document argues that carbon dioxide capture and storage (CCS) is a critical interim technology for developing countries to decouple fossil fuel use from CO2 emissions without disrupting national development goals. However, it notes that deployment in Africa, Asia, and Latin America is hindered by high costs and insufficient financing mechanisms. The paper advocates for accelerated CCS demonstration in non-OECD contexts to reduce technology risks and costs, aligning with the IEA CCS Roadmap's goal of 50 projects over 10 to 20 years.

The document defines Locally Led Adaptation (LLA) as the devolution of authority and resources to local actors—particularly marginalized groups—to give them agency over the design and delivery of climate adaptation. It highlights a significant funding gap, noting that less than 10% of global climate fund finance reached local levels between 2006-2016. To address this, the document promotes the 8 LLA Principles, launched at the 2021 Climate Adaptation Summit, and calls for 25% of climate finance to be dedicated to LLA, potentially increasing toward the LDC Group's target of 70% by 2030. It emphasizes the necessity of grant-based finance for public goods and low-income communities to build the resilience required to attract larger private investments.

The report argues that while land restoration offers high economic returns—estimated at $7 to $30 for every dollar invested—it remains severely underfunded with an annual gap of approximately $300 billion. It identifies seven systemic barriers to investment, including the lack of market value for public benefits and long investment horizons. The authors recommend a cross-sectoral government approach, the use of carbon taxes to fund restoration, and the implementation of risk-mitigation tools like first-loss guarantees and tax credits to attract private capital. The document also provides a framework for economic valuation to make the full suite of ecosystem services visible to decision-makers.
