Organizationally, SEI reports a 52% reduction in air travel emissions per employee since 2017 and an increase in peer-reviewed journal outputs by 30% over 2024.

The document analyzes Nigeria's transport sector, which is heavily dependent on fossil fuels and accounts for 24% of national GHG emissions. It evaluates current policies, emerging green initiatives like the P-CNGI and Lagos E-Mobility Project, and provides recommendations for integrating climate action into national transport planning, drawing on lessons from Ethiopia and Kenya.

The document defines fossil fuel subsidies as mechanisms that price fuels below real costs, noting that explicit subsidies reached USD 1.1 trillion in 2023, while total estimates including climate and health costs exceed USD 7 trillion. It argues that these subsidies distort markets, encourage overconsumption, and undermine energy security by increasing vulnerability to global price shocks. The guide highlights that reform can reduce CO2 emissions by 1%–10% by 2030 and generate fiscal savings for reinvestment in clean energy. It notes that broad subsidies often disproportionately benefit high-income households, with the top 20% receiving up to six times more benefits than the poorest 20%. Examples of successful reforms are cited from Indonesia, India, and Italy. The document also details the role of COFFIS in improving transparency through national subsidy inventories and phase-out plans.

The document outlines green bonds as fixed-income instruments for environmental projects, noting that energy and buildings each account for approximately 30% of recent allocations. It identifies institutional investors as the core demand source and highlights the role of Multilateral Development Banks (MDBs) in providing cumulative issuances, such as the World Bank's over USD 200bn. The text details the issuance process, noting a typical 'greenium' of 2–5 bps and a timeline of 6–12 months for sovereign framework preparation.

The report evaluates Moldova's progress toward climate neutrality by 2050, identifying 'Some Progress' in most sectors but 'Little Progress' in zero pollution. Key challenges include heavy reliance on energy imports, outdated building stock, linear waste management, and a significant financing gap, while enablers include EU accession aspirations and international donor support.

The report evaluates Ukraine's green transition readiness, identifying 'Significant Progress' in climate change and energy, 'Some Progress' in clean industry, buildings, transport, agriculture, biodiversity, and finance, and 'Little Progress' in zero-pollution, just transition, digitalization, and research and innovation. It emphasizes the need for high-level coordination, a national sustainable finance taxonomy, and the integration of 'build back better' principles into post-war reconstruction to achieve climate neutrality by 2050.

The document argues that the adoption of zero-emission trucks (ZETs) in India is hindered by a lack of affordable financing and the risk-aversion of private capital. It recommends that public-sector actors, including government officials and multilateral development banks, utilize concessional debt, risk-sharing mechanisms, and policy-driven incentives to de-risk investments and stimulate private-sector participation to meet net-zero goals.

The report details the outcomes of a WRI conference in Bogota, where teams from Brazil, Colombia, and Mexico developed a joint vision to synchronize electric mobility deployment with air quality monitoring. It proposes three primary regional projects: a 'Healthy and Sustainable Path to School' initiative to reduce child exposure to pollutants, a regional health-impact calculator platform (QueTanLimpioEsTuAire.com), and a 'Fleets in Transition' project targeting the decarbonization of urban freight. The document emphasizes a focus on vulnerable populations, including children and the elderly, and aims to position WRI as a regional leader in integrated sustainable transport solutions by 2030.

The document details the history and global expansion of Bogota's Ciclovía, a weekly event closing 127 kilometers of roads to cars. It examines how this model inspired similar programs like CicLAvia in Los Angeles, Ciclodia in Lima, and Open Streets Cape Town, highlighting their roles in promoting sustainable transport, social cohesion, and local economic growth.

North Somerset Council is utilizing Britain Talks Climate (BTC) data to refine its climate communications, focusing on avoiding polarizing language and using frames like 'resilience' to build public support. The Council is currently piloting targeted messaging for rooftop solar installations in specific neighborhoods, tailoring both the content and the messengers based on BTC audience segments. Additionally, the Council is integrating BTC insights into its transport strategy to address the fact that transport accounts for 45% of the area's emissions, aiming to drive behavior change through trained community champions.

The document highlights the significant influence of French banks on the automotive market, noting that five major groups control 34% of leasing contracts. It criticizes these banks for lacking a phase-out date for internal combustion engine rentals and for a low proportion of electric vehicles in their fleets compared to market averages, particularly at BNP Paribas and Société Générale.

The guide establishes a standardized framework for tracking climate mitigation, adaptation, and biodiversity finance. It provides detailed lists of eligible activities for mitigation, a three-step validation process for adaptation, and specific criteria for biodiversity finance. The document emphasizes the use of ex-ante GHG emission reduction assessments and offers methodologies for quantifying finance through incremental or proportional approaches to ensure transparency and avoid double-counting.

The report finds that while climate finance in Africa grew by 48% to USD 43.7 billion in 2021/22, it remains severely insufficient, meeting only 23% of the annual needs required for NDC implementation. Public finance dominates the landscape, providing 82% of total flows, while private finance is heavily concentrated in energy systems and a small number of countries. The document highlights a critical 'trilemma' where climate-vulnerable countries are also debt-distressed and conflict-affected, further hindering their ability to attract investment. Key recommendations include scaling the use of guarantees, improving domestic capital market regulations, and enhancing the transparency and equity of voluntary carbon markets.

Climate finance in Africa grew by 48% between 2019/20 and 2021/22, reaching USD 43.7 billion, yet this remains only 23% of the annual funding required to meet 2030 NDC goals. Public finance dominates the landscape, providing 82% of total flows, while private finance is heavily concentrated in energy systems and a small number of countries. The report highlights a critical 'trilemma' where climate-vulnerable countries are often simultaneously debt-distressed and conflict-affected, further hindering their access to grants and affordable capital. Key recommendations include reforming domestic fiscal policies to remove fossil fuel subsidies, scaling the use of guarantees to de-risk private investment, and leveraging domestic institutional assets, such as pension funds, to reduce reliance on international debt.

The document outlines a SAVi assessment for a proposed MRT system in Pampanga, Philippines, consisting of four bus rapid transit (BRT) lines and one light rail transit (LRT) line. It employs system dynamics modelling and causal loop diagrams to compare a 'no action' scenario against the MRT implementation, identifying potential co-benefits such as reduced CO2 emissions, decreased traffic congestion, and increased regional connectivity. The assessment provides a detailed set of assumptions and data sources for calculating capital costs, operational revenues, and avoided costs related to health, accidents, and fuel use.

The FSD Program addresses the funding gap for the Paris Agreement and Sustainable Development Goals by shifting focus from the supply side of finance to the demand side. By analyzing firm-level investment decisions in low- and lower-middle-income countries (LLMICs), the program identifies the enabling conditions and blended-finance instruments—such as guarantees and risk mitigation—necessary to make sustainable projects attractive to private investors. This micro-level evidence is then used to inform macro-level global and regional policy frameworks.

The report evaluates claims made by candidates from the Socialist Party, Renew, La France insoumise, and Les Écologistes across five key sectors: transport, housing, agriculture, international trade, and finance. It corrects misconceptions regarding railway privatization, energy renovation rates, agricultural demographics, and the financial impact of proposed green taxes.
