This 2020 report by the Stockholm Environment Institute analyzes Green Public Procurement (GPP) in Estonia and Europe. It defines GPP as a subset of sustainable procurement focusing on life-cycle environmental impacts. Finding that GPP represented only 3% of Estonian procurements in 2018, the report provides legal analysis, comparisons with countries like Austria, Bulgaria, and Spain, and detailed technical GPP criteria for products such as sanitary faucets, toilets, and urinals to encourage wider adoption.

The document assesses how constraints on biomass, specific metals, and water resources may impact the transition to a low-carbon economy. It evaluates various scenarios for biomass production, predicts cumulative deficits for metals like indium and tellurium, and examines the water-energy nexus, using a California case study to demonstrate how technology choices can mitigate water stress while reducing emissions.

The document identifies critical gaps in current disaster risk reduction (DRR) efforts, specifically the neglect of cultural and contextual factors in vulnerability assessments. It argues that DRR, climate change adaptation, and development are currently 'siloed' and must be integrated to avoid unsustainable patterns of exploitation and loss. The authors call for a shift from top-down, expert-driven governance to transformative, bottom-up approaches that incorporate local knowledge and non-economic assets. To achieve this, they propose using holistic, mixed-method research tools, such as Knowledge Elicitation Tools (KnETs), to better understand the tacit drivers of decision-making and organisational culture.

The report estimates that the 2019 carbon footprint of EU military expenditure was approximately 24.8 million tCO2e, equivalent to the emissions of 14 million average cars. It identifies significant data gaps and a lack of transparency in GHG reporting across EU member states and military corporations, often justified by national security. The study highlights France as the largest contributor to the EU military carbon footprint and Poland's military technology industry as a high emitter due to its coal-reliant electricity grid. It recommends urgent reviews of security strategies to reduce armed force deployment, mandatory transparent GHG reporting for militaries and contractors, and the implementation of reduction targets aligned with the Paris Agreement.

The document consists of three tables identifying corporations and organisations involved in fossil fuels and arms. It details the roles of various oil, gas, and coal companies, their reserves rankings, and their environmental records. It also lists global arms manufacturers, their involvement in nuclear weapons programmes, and UK military entities, highlighting ethical concerns regarding recruitment and military strategy.

The report argues that the United States can significantly reduce its reliance on fossil fuels by deploying a diverse mix of renewable energy sources, which have the technical potential to meet current electricity needs many times over. It highlights wind, solar, geothermal, bioenergy, and hydropower as key resources, noting that wind and geothermal are already competitive with new coal and natural gas plants in some cases. The document identifies critical barriers to this transition, including the need for a modernized transmission grid, streamlined siting processes, and sustainable biomass harvesting. It proposes a policy package featuring a national renewable electricity standard (RES) ramping up to 40% by 2030, extended tax credits, and increased R&D funding. While discussing carbon capture and storage (CCS) and advanced nuclear power as potential low-carbon supplements, the report notes significant cost uncertainties, infrastructure requirements, and safety risks associated with these technologies.

The We Mean Business Coalition analyzed 30 early adopters of the EU's Corporate Sustainability Reporting Directive (CSRD) to showcase innovative solutions for challenging disclosure requirements. The report highlights diverse approaches to double materiality assessments, TCFD-aligned climate risk quantification, Scope 3 emissions 'hot-spotting', and supply chain due diligence. It emphasizes that while many early adopters are only partially aligned with the regulation, their methods for reporting on internal controls, whistleblower cases, and climate transition action plans serve as practical guides for companies facing mandatory reporting from 2024.

The report analyzes the first wave of CSRD climate reports from 93 large EU companies, finding that while limited assurance is standard, many companies are restating or erasing historical data to improve quality. It identifies a trend toward integrating sustainability internal controls with financial systems and notes that while GHG reporting is improving, monetized climate risk and opportunity reporting remain rare. The document also evaluates the adoption of the EU Taxonomy and the reporting of political lobbying and climate-related executive incentives.

The report argues that Concentrating Solar Thermal power (CST) is a viable large-scale, zero-carbon alternative to coal-fired power, particularly when combined with thermal storage to meet baseload demand. While currently more expensive than coal, costs are expected to decline through technology learning, R&D in materials and optical design, and economies of scale from larger plants. The document highlights that a carbon price of approximately $115 per ton of CO2 would make CST with 6 hours of storage economically competitive with coal. It emphasizes the need for stable policy support, such as feed-in tariffs, to bridge the current cost gap and calls for increased deployment in rapidly developing economies like China and India to alter their emissions trajectories. Additionally, the report notes that widespread CST adoption requires improved transmission infrastructure, specifically federal coordination in the U.S. and links between the EU and North Africa.

The paper identifies key factors and recommendations for achieving 'transformational' change in low-carbon energy, defined by large magnitude impact, non-linear growth, and long-term sustainability. Through the analysis of 20 case studies, the authors categorize experiences into transformational, potentially transformational, and missed opportunities, highlighting the roles of regulatory frameworks, financial incentives, and national ownership.

The document details mechanisms for raising public finance for climate action, focusing on the roles of international funding, debt instruments, and national vehicles. It examines the benefits and challenges of international public finance, the growth of the climate bond market, the utility of debt-for-climate swaps in reducing debt burdens, and the operational structure of national climate funds. The guide provides specific examples of these instruments in practice across various developing and middle-income countries.

The document examines the critical issues surrounding the finalization of Article 6 of the Paris Agreement, which governs international cooperation through carbon markets. It argues that strong rules are essential to prevent double counting and ensure additionality, as failures in these areas could increase global emissions and weaken Nationally Determined Contributions (NDCs). Furthermore, the paper highlights that the design of Article 6 will influence the cost-effectiveness of emissions reductions, the flow of finance for climate activities, and the funding available for the adaptation fund through a share of proceeds.

The document argues that open data—datasets freely available for use and redistribution—is essential for a coordinated, whole-of-society response to climate change. It identifies five primary benefits of open data: improved data coordination and quality, more informed decision-making, the creation of novel partnerships, the democratization of climate modeling, and enhanced monitoring of policies and programs. The paper draws on a literature review, expert consultations, and pilot projects in Chile and Uruguay (conducted between August 2019 and August 2020) to provide a methodology for stakeholders to assess and improve the openness of climate-relevant datasets.

The report outlines strategies for U.S. companies to adopt on-site renewable energy, focusing on solar, wind, geothermal, and solar thermal technologies. It details various ownership and financing models—ranging from direct ownership to third-party power purchase agreements—and analyzes the associated financial incentives, operational risks, and corporate benefits such as cost hedging and brand enhancement.

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.

WWF Spain implemented a conservation project in the Riaza River Natural Park to protect amphibians from climate change and habitat loss. Key actions included installing ramps at five water points, creating one new water point, and converting six abandoned siphons into shelters. The project also produced an agricultural guide for amphibian-friendly farming and engaged over 100 local volunteers, reaching an estimated 750,000 people through communication efforts.

The document outlines a strategic framework to transform ocean conservation by moving from incremental to revolutionary solutions. It identifies ten Grand Challenges—ranging from unsustainable aquaculture and marine debris to ocean acidification and dead zones—and proposes a pipeline for innovation. This pipeline involves sourcing ideas through open innovation and prizes, prototyping and incubating them through dedicated accelerators, and scaling them via a tiered investment model. The initiative seeks to build a multidisciplinary 'Tribe' of solvers, including technologists and financiers, to increase the speed and efficacy of marine protection.

The document identifies bottling partners across the Coca-Cola system that have implemented ten energy-efficiency measures. These measures are designed to help the company achieve up to 70 percent of its carbon reduction target while providing financial returns and environmental benefits. The text provides a chronological list of plants that completed the challenge between August 2012 and May 2018.

The guide outlines a structured approach to achieving deforestation- and conversion-free (DCF) leather supply chains, emphasizing the transition from fragmented mapping to event-based traceability. It advocates for the adoption of global standards, specifically GS1 EPCIS, to ensure data interoperability across complex multi-tier networks. The document details an 11-step implementation roadmap, ranging from internal assessments and pilot projects with trusted partners to the integration of geospatial analysis and third-party verification. It distinguishes between serialized traceability for individual animals and lot-based traceability for processed hides, proposing a hybrid model to balance precision with operational feasibility.

The document details water stress in cities including São Paulo, Mexico City, Karachi, Los Angeles, Nairobi, Brisbane, and Seville, highlighting the roles of poor planning, climate-driven drought, and infrastructure failure. It advocates for a transition to climate-resilient water budgets through demand reduction, diversified water sources, and improved governance to avoid 'Day Zero' scenarios.
