This briefing by Zero Carbon Analytics discusses the findings of the IPCC Sixth Assessment Report (AR6), specifically the Working Group II (WGII) report on impacts, adaptation, and vulnerability. It outlines the severe effects of human-induced climate change on ecosystems and humans, the increasing frequency of extreme weather, the disproportionate impact on marginalised populations, and the critical need for transformative adaptation and mitigation to avoid catastrophic economic and social costs.

The KE4CAP Impact Report describes the outcomes of the Knowledge Exchange between Climate Adaptation Platforms (KE4CAP) project, which created a global network for practitioners to improve the reach and effectiveness of climate adaptation platforms.

This report assesses progress toward Goal 5 of the New York Declaration on Forests (NYDF), which aims to restore and maintain 350 million hectares of landscapes and forestlands by 2030. It highlights a significant gap between political commitments and actual implementation, noting that previous targets were not met and that monitoring remains technically challenging.

This report examines the critical role of sustainable cooling and cold chains in reducing global food loss, improving nutrition, and supporting agricultural economies, particularly in low-income and high-impact countries.

This briefing by Zero Carbon Analytics examines the environmental and climate impacts of the global livestock sector, arguing that a shift toward plant-based diets and alternative proteins is essential to meeting climate targets. It details the growth of meat production, the role of government subsidies in supporting industrial agriculture, and the emerging market for alternative proteins, while highlighting the need for systemic policy changes and a reduction in meat consumption, particularly in high-income regions.

This briefing by the Climate Policy Initiative (CPI) proposes a methodology to track incremental energy efficiency investments in certified green buildings. Using a global database of over 16,000 certifications from 2019-2020, the report argues that current green certifications are often inconsistent indicators of actual energy performance and that energy efficiency investments represent only a small fraction of total building construction costs.

This research paper examines the potential for cross-border climate change impacts to affect the European Union through trade, human security, and finance, identifying specific regional 'hotspots' of risk despite overall uncertainty in the current research.

This policy brief examines the development and implementation of the Minamata Convention on Mercury, a legally binding global treaty designed to protect human health and the environment from mercury emissions and releases. It details the transition from regional marine protections to a comprehensive global framework, the specific challenges posed by artisanal and small-scale gold mining (ASGM), and the reasons why mercury was addressed separately from other toxic heavy metals like lead and cadmium.

This case study describes the development of a zero-emissions transportation ecosystem in Cincinnati, focusing on the collaboration between Servall Electric, an electrical contractor, and Workhorse, a local manufacturer of electric last-mile delivery step vans.

This briefing by Zero Carbon Analytics prepares readers for the release of the IPCC's 6th Assessment Report (AR6) 'The Physical Science Basis'. It outlines major climate science developments since the 5th Assessment Report (AR5), focusing on human attribution of extreme weather, updated carbon budgets, refined climate sensitivity models, the role of non-CO2 greenhouse gases, and the complexities of net-zero and carbon dioxide removal.

The 2021 State of Cities Climate Finance report provides a comprehensive estimate of global urban climate finance, identifying a significant gap between current annual investments of USD 384 billion and estimated needs of USD 4.5 to 5.4 trillion. It analyzes the enabling conditions required to mobilize finance and offers recommendations for city, national, and international officials to accelerate low-carbon, climate-resilient urban development.

This executive summary of the 2021 State of Cities Climate Finance report, produced by the Cities Climate Finance Leadership Alliance with World Bank contributions, analyzes global urban climate investment flows and the enabling conditions required to close the investment gap. It establishes a framework for tracking urban climate finance and provides recommendations for city, national, and international officials to mobilize the trillions of dollars needed for low-carbon, climate-resilient urban development.

This executive summary of the 2021 State of Urban Climate Financing report, produced by the Cities Climate Finance Leadership Alliance with World Bank contributions, analyzes global urban climate investment flows, identifies significant funding gaps—particularly in developing nations—and proposes a framework of 'enabling conditions' to mobilize the trillions of dollars needed for low-carbon and climate-resilient urban development.

This executive summary of the 2021 report 'État du financement climatique des villes' analyzes the current state of urban climate investment, identifies significant funding gaps—particularly in developing nations and for adaptation efforts—and proposes frameworks to mobilize the trillions of dollars required for low-carbon, resilient urban development.

This executive summary of the 2021 report 'O Estado do Financiamento Climático das Cidades' (The State of City Climate Finance), produced by the Cities Climate Finance Leadership Alliance (CCFLA), analyzes current urban climate investment levels, identifies barriers to funding, and proposes frameworks to mobilize the necessary capital for low-carbon and resilient urban development.

This executive summary of the 2021 State of Cities Climate Finance report, produced by the Alliance for Leadership in City Climate Finance with World Bank contributions, analyzes global urban climate investment flows, identifies barriers to funding, and proposes frameworks to mobilize the trillions of dollars needed for low-carbon and resilient urban development.

This report by the Climate Bonds Initiative analyzes post-issuance reporting practices for 694 green bonds (USD 212bn) issued between November 2017 and March 2019. It finds that while use-of-proceeds (UoP) reporting is widespread, impact reporting is less common and highly unstandardized. The study evaluates reporting quality through a scoring system, identifies best practices, and advocates for a global, harmonized reporting framework to move beyond binary labels toward absolute, entity-level sustainability assessments.

This briefing, prepared by the Executive Directorate of the Inter-American Institute for Global Change Research (IAI), presents a proposed Gender Policy for IAI scientific projects and activities. The policy aims to ensure gender equality in research and capacity building, recognizing that gender is a social construct and not binary. It establishes five primary objectives to promote regional leadership in gender equality, integrate gender dimensions into science, eliminate selection biases, create inclusive research environments, and develop gender-focused training.

The Inter-American Institute for Global Change Research (IAI) has developed a Gender Policy on IAI Projects and Activities to ensure gender equality and the mainstreaming of women and individuals with diverse gender identities across its scientific research, capacity building, and science-policy initiatives.

This policy brief examines the measurement and management of fishing capacity within the framework of World Trade Organization (WTO) negotiations to discipline fisheries subsidies. It provides technical definitions of capacity, overcapacity, and overfishing based on FAO guidelines, and discusses the challenges of monitoring these metrics in multi-species and artisanal fisheries. The document also analyzes global fleet trends from 1950 to 2015, noting a significant increase in vessel numbers and engine power alongside a decline in stock abundance.
