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.

The Green Finance Mapping Report 2020, published by the Climate Policy Initiative, analyzes the 2019 green finance commitments of the International Development Finance Club (IDFC). It details a rebound in green finance to $197 billion in 2019, with a heavy concentration in climate mitigation and a growing trend in adaptation finance. The report also examines the distribution of these funds between OECD and non-OECD institutions and their alignment with the Paris Agreement.

This research paper evaluates the 2018 WHO global ambient air quality database, which tracks PM10 and PM2.5 levels across thousands of cities. It notes that while high-income regions report low pollution, low- and middle-income regions in Africa, Southeast Asia, and Latin America face high levels and resource barriers. The paper warns that the database has been used to draw misleading city-to-city comparisons and proposes improvements based on criteria like data completeness and quality control.

A fact sheet detailing a JPY 2 billion green loan issued by Dream Private REIT on January 31, 2020, used to refinance the DPR Hiratsuka Logistics Center, which holds a 5-star BELS certification.

The 2019 Global Landscape of Climate Finance report by the Climate Policy Initiative analyzes global climate-related primary investment from 2013 to 2018. It finds that while annual climate finance reached record levels, crossing the USD half-trillion mark in 2017 and 2018, current investment levels remain significantly below what is required to meet the goals of the Paris Agreement and a 1.5 ˚C scenario.

This report by the Climate Policy Initiative (CPI) provides updated estimates of global climate finance flows for 2015 and 2016, incorporating new data on electric vehicle sales and national development finance institutions. It analyzes the distribution of these flows by actor, sector, and region, while discussing the challenges of tracking adaptation and energy efficiency investments and the operationalization of Article 2.1(c) of the Paris Agreement.

This working paper analyzes the experiences of seven Development Finance Institutions (DFIs) between 2011 and 2014 to identify strategies for driving private sector investment in climate resilience, specifically within agriculture, water-intensive industries, and infrastructure.

This executive summary by the Center for International Environmental Law (CIEL) argues that stricter laws and regulations regarding hazardous chemicals act as drivers for innovation rather than obstacles. By analyzing patent filings and case studies, the document demonstrates how the prospect of stronger regulation encourages the development and market adoption of safer chemical alternatives.

This briefing analyzes the divergent methods used to quantify the GHG emissions impact of new fossil fuel infrastructure. It contrasts the 'literalist' view (full combustion emissions), the 'fatalist' view (zero net impact due to displacement), and the 'economist' view (increased consumption due to lower prices). The authors conclude that a net-zero impact is highly unlikely due to market responses and systemic 'lock-in' effects.

The CRED v.1.4 Technical Report describes the methodology of the Climate and Regional Economics of Development (CRED) model, an integrated assessment model designed to estimate the optimal pace and distribution of global investment in emissions mitigation and climate policy costs.

This policy brief by the Stockholm Environment Institute (SEI) discusses the challenges of providing sustainable energy access to the global poor while meeting climate goals. It presents three scenarios—Baseline, Basic Energy Access (BEA), and Shared Development Agenda (SDA)—to explore the energy systems required to enable long-term economic development. The document argues that market-based instruments alone are insufficient and calls for a transformative global governance framework, increased state-led investment in innovation, and the integration of energy targets into Sustainable Development Goals (SDGs).

This technical policy briefing note from the ClimateCost project assesses the potential health impacts and economic costs of climate change in Europe, specifically focusing on heat-related mortality, food-borne diseases, coastal flooding, and labour productivity. It compares a medium-to-high emission scenario (A1B) with a mitigation scenario (E1) and evaluates the role of adaptation and autonomous acclimatisation in reducing these risks.

This report by the Stockholm Environment Institute evaluates the current state of climate economics, arguing that economic modeling has lagged behind climate science. The authors advocate for a precautionary, standards-based approach to policy—such as maintaining a 2°C warming limit—rather than relying on traditional cost-benefit frameworks that often underestimate catastrophic risks and the importance of future generations.

This technical policy briefing note describes the climate change projections used in the ClimateCost project, focusing on temperature and precipitation changes globally and across Europe. It evaluates three emission scenarios—A1B (medium-high), E1 (mitigation), and RCP8.5 (high)—using a combination of Global Climate Models (GCMs) and Regional Climate Models (RCMs) to assess future impacts and the associated uncertainties.

The evaluation of the Sustainable Development Communications Network (1996-2001) finds that the network successfully established the SD Gateway as a leading global portal for sustainable development knowledge, particularly for the global south, and effectively built the communications capacity of its members through collaborative projects. However, it faced challenges with institutional priorities overriding network goals and a lack of member-led fundraising. The report recommends shifting to a 'community of practice' model focused on individual practitioners rather than institutional membership.

This 1989 research paper by Amory B. Lovins of the Rocky Mountain Institute argues for the creation of markets in resource efficiency to combat the economic tendency to treat natural resource depletion and pollution as free goods. Lovins proposes treating saved resources—such as 'negawatts' of electricity—as commodities that can be traded, auctioned, and hedged, providing a market-based alternative to regulatory mandates. He asserts that efficient technology is generally cheaper than producing new resources, creating a significant profit opportunity for those who sell efficiency rather than the resource itself.

This fact sheet from the Climate Policy Initiative provides an overview of public adaptation finance flows, primarily for the year 2013, detailing the sources, instruments, sectors, and geographic destinations of these funds.

This research paper examines the rise of transnational organised crime (TCOs) as a global security threat, analyzing how globalisation and the erosion of state authority have facilitated the growth of criminal networks. It explores the relationship between TCOs and various state types—particularly weak and transitional states—and provides a typology of state roles in facilitating or combating illicit activities. The document details the operational characteristics of TCOs, including their use of ethnic networks and risk management strategies, and assesses the specific threats they pose to national security, financial systems, and human rights.

This research paper by Amory B. Lovins of the Rocky Mountain Institute (RMI) proposes the 'hypercar'—a vehicle combining ultralight mass, ultralow aerodynamic drag, and hybrid-electric drive to achieve fuel economies 4–10 times higher than conventional cars. The author argues that by using advanced composites and recursive design, manufacturers can reduce costs and mass simultaneously, bypassing the incremental improvements of the traditional automotive industry to create a more efficient, safer, and cheaper vehicle.

This executive summary, produced by the Stockholm Environment Institute for the Combat Climate Change (3C) initiative, examines how resource scarcity in biomass, metals, and water could hinder the transition to a low-carbon economy. It evaluates various scenarios for resource availability and proposes strategies—including technological innovation, policy shifts, and efficiency improvements—to ensure the viability of green technologies.
