The World Resources Institute (WRI) employs a comprehensive greenhouse gas (GHG) accounting methodology covering Scope 1, 2, and 3 emissions. The inventory uses an operational control consolidation approach and has established 2019 as its base year for 2030 reduction targets. Scope 1 includes direct emissions from diesel generators and office refrigerators. Scope 2 utilizes both location-based and market-based methods for purchased electricity, incorporating renewable energy certificates for US operations. Scope 3 is the most extensive, covering purchased goods and services (Category 1) via a spend-based USEEIO model, fuel- and energy-related activities (Category 3), waste (Category 5), business travel (Category 6), employee commuting (Category 7), and endowment investments (Category 15). The methodology emphasizes the use of regional emission factors and annual staff surveys to estimate impacts across WRI's global network.

The report argues that despite improvements in material efficiency, the total volume of waste entering the environment continues to increase because economic growth and consumer lifestyles offset efficiency gains. It highlights a critical gap in national accounting, noting that while financial transactions are tracked via GDP, there is no equivalent system for measuring the physical material requirements of modern economies.

The document advocates for the implementation of high-quality, safe 'pop-up' bike lanes to support the surge in cycling during the pandemic. It emphasizes that temporary measures must not compromise safety standards, as poor design increases risks for cyclists, who account for 3% of global road traffic deaths. The guide aims to help cities integrate these temporary lanes into broader mobility strategies and speed management systems to ensure long-term sustainability and public health.

The report argues that the deployment of commercial-scale carbon capture and storage (CCS) depends significantly on local community acceptance and the quality of the engagement process. It emphasizes that effective engagement is measured by the success of the process itself, rather than whether all parties agree on the project's outcome. The guidelines are designed for three primary stakeholders: project developers, regulators, and local decision-makers, aiming to move beyond simple public education toward a culture of two-way communication to ensure local values and ecosystems are respected while pursuing climate mitigation goals.

The document defines a carbon tax as a fee on fossil fuels and primary products based on greenhouse gas emissions, providing a financial incentive for reduction. It distinguishes carbon taxes from cap-and-trade programs by noting that taxes set a price without an emissions limit, whereas cap-and-trade sets a limit with a market-determined price. The text details how these taxes are typically applied upstream and passed to downstream consumers, noting that the economic impact on businesses and lower-income individuals depends on whether revenues are 'recycled' through rebates or tax cuts to maintain revenue neutrality. It mentions international implementations in Europe, Japan, and British Columbia, and notes the political difficulty of establishing a national carbon tax in the United States.

The transport sector accounts for 24% of global CO2 emissions from fuel combustion, with road transport comprising nearly three-quarters of that total. To limit global warming to 1.5 °C, the IPCC projects the transport sector must be zero-emission by 2050. WRI employs a systems-thinking approach to decarbonization, focusing on eight key areas: clean energy integration, roadmapping and policy, fleet electrification, sustainable e-mobility, integrated climate planning, equitable transition, consumer behavior, and sustainable materials. WRI's global team of over 100 experts provides research, implementation support, and stakeholder coordination to ensure the transition enhances social equity and minimizes ecological damage.

The report argues that traditional 'gray' infrastructure alone is insufficient to meet global development goals and climate adaptation needs. It proposes a 'next generation' approach that combines built solutions with 'green' systems—such as forests, wetlands, and mangroves—to improve water supply, flood management, and hydropower efficiency. The authors provide a framework for evaluating these projects across technical, environmental, social, and economic dimensions, emphasizing that green infrastructure can lower costs, increase resilience, and empower local communities if rigorously designed and supported by enabling policies and innovative financing.

The report argues that combining natural systems—such as forests, wetlands, and mangroves—with built infrastructure can lower costs and increase resilience against climate change. It provides a technical, social, and economic framework for project appraisal and highlights the need for enabling policies and innovative financing to mainstream these 'next generation' infrastructure solutions.

The World Resources Institute (WRI) is implementing a 2023-2027 strategy to drive systemic change across three human-centered systems: Cities, Energy, and Food, Land & Water. WRI Europe Stichting serves as the regional representative in Europe, leveraging the region's financial and research hubs to pilot sustainable practices and mobilize funding. The organization utilizes a framework of Global Impact Targets, WRI Impact Targets, and Country-Level Targets to measure success, aligned with the Paris Agreement and Sustainable Development Goals. WRI Europe Stichting's financial report for the 2024/2025 period shows a total income of EUR 17,360,351 and a result for the year of EUR 153,834.

The document outlines the achievements of the Global Commission on Adaptation, specifically the role of the World Resources Institute (WRI) in co-managing the initiative. It highlights the 'Adapt Now' report, which argues that climate adaptation is a human, environmental, and economic imperative, with benefit-cost ratios for investments ranging from 2:1 to 10:1. The report details a 'Year of Action' that mobilized over 170 partners across tracks including finance, agriculture, resilient cities, and nature-based solutions. Key outcomes include the mobilization of $790 million for small-scale food producers, the creation of the 'Principles for Locally Led Adaptation', and the launch of the '1,000 Cities Adapt Now' program. The document concludes by calling for scaled-up climate finance for developing countries and the integration of climate risks into national budgetary and policy decisions.

The document explains the methodology of 'extreme event attribution' to help journalists avoid common errors, such as ignoring climate change or attributing an event to it as a sole cause. It details how scientists use climate models to compare the modern world with a pre-industrial one to determine if an event was more likely or intense due to global warming. The guide provides specific scientific consensus and limitations for heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires, emphasizing that while some connections are robust (e.g., heatwaves), others are more complex and depend on regional data and human vulnerability.

The study finds that the July 2019 heatwave in Western Europe was made significantly more likely and intense by human-induced climate change. In France and the Netherlands, the event would have been extremely improbable without human influence, with return periods exceeding 1,000 years. Across all analyzed locations, the heatwave was 1.5 to 3 °C hotter than it would have been in an unchanged climate. The analysis utilized a combination of observational data and eight climate model ensembles, noting that while models generally underestimate temperature trends and overestimate variability, they still simulate large probability changes.

The study concludes that human-induced climate change significantly increased the probability of the 2022 summer soil moisture droughts in both West-Central Europe and the Northern Hemisphere extratropics, primarily driven by a strong increase in high temperatures rather than precipitation deficits. For West-Central Europe, the likelihood of root-zone soil moisture drought increased by 3-4 times and surface soil moisture drought by 5-6 times. In the Northern Hemisphere extratropics, the increase was more pronounced, with the likelihood of root-zone drought increasing by at least 20 times and surface drought by at least 5 times. These conditions led to severe impacts on agriculture, energy production, and water infrastructure, compounded by socio-economic stressors such as the conflict in Ukraine.

The study concludes that the June 2019 heat wave in France was made at least five times more likely due to human-induced climate change. Observational data suggests a much higher increase in probability and a temperature rise of approximately 4ºC compared to a century ago, though climate models generally show lower trends and systematic biases in representing heat wave variability.

The document explains how 'attribution' studies determine if global warming increased the likelihood or intensity of a specific extreme weather event. It warns journalists against three common errors: ignoring climate change, claiming it caused an event without evidence, or treating it as the sole cause. The guide provides specific findings for heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires, noting that while heatwaves are globally linked to warming, other phenomena like droughts and floods vary significantly by region.

Kipster is expanding its circular egg production model from the Netherlands to the US, partnering with MPS Egg Farms and The Kroger Co. The model focuses on using surplus food for feed, achieving carbon neutrality through renewable energy and offsets, and improving animal welfare by raising roosters for meat instead of culling them. In the US, the operation is based in Indiana, utilizing pasta surplus and other by-products to reduce land use and greenhouse gas emissions.

The report argues that large-scale US dairies can reach net zero emissions within five years by integrating specific technologies and practices, potentially increasing annual net returns to $1.9 million per dairy. Key strategies include precision agriculture, feed additives to reduce enteric methane, and anaerobic digesters that convert manure and organic substrates into renewable energy and fertilizers. The analysis emphasizes that while technologies exist, achieving these goals requires significant policy shifts, such as expanded water quality trading markets and improved EPA processing of renewable fuel pathways.

The report by Zero Carbon Analytics (ZCA) highlights the severe health and economic costs associated with the overconsumption of red and processed meats. Using data from the Global Burden of Disease study, ZCA finds that processed meat caused 295,000 deaths and red meat caused 334,000 deaths globally in 2021. The economic impact reached USD 285 billion in 2020. The analysis reveals a 'treatment-over-prevention' trend in wealthy nations—specifically in Europe, North America, Oceania, and Asia—where robust healthcare systems spend heavily to manage preventable chronic diseases rather than investing in dietary prevention. For example, Switzerland may spend up to USD 99,000 to avert one disability-adjusted life year (DALY) from processed meat. The report argues that a 30% reduction in the disease burden from processed meat could save billions annually in the US, Germany, UK, and France, allowing for the redirection of funds toward other health priorities, such as nursing staff.
