A research paper by OCP and IISD examines the ability of the European Union's Public Procurement Data Space (PPDS) to track the actual environmental impact of green public procurement (GPP). The authors argue that while current monitoring focuses on intent (whether environmental objectives were declared), it is possible to estimate real-world carbon savings using existing data and spend-based estimation. A pilot study using German data in the construction and vehicle sectors suggests that the potential for emissions reductions is significantly higher than what is currently being achieved through green-tagged contracts.

This report evaluates a pilot project in Uttar Pradesh, India, that used the spare capacity of solar irrigation pumps (SIPs) to power village grain mills, identifying both the socio-economic benefits and the operational constraints of such secondary power uses.

This technical brief describes Phase 2 of the Carbon Rating Framework developed by the Climate Policy Initiative (CPI). The framework aims to integrate emissions performance into financial decision-making by assigning a carbon rating (CR1–CR10) based on a company's emissions intensity relative to its revenue. Phase 2 involved testing the framework on a sample of 50 companies to validate its feasibility and ability to differentiate emissions performance across various sectors.

This methodology report describes the development and piloting of an integrated cost-benefit analysis (CBA) model designed to estimate the direct and indirect benefits of nature-based infrastructure (NBI)—such as conservation and reforestation—for road resilience in Indonesia. The model expands traditional CBA by incorporating 'non-road' benefits, including socio-economic and environmental externalities, to provide a more holistic view of the value of investing in climate-resilient infrastructure.

This research paper by the Stockholm Environment Institute explores how systems thinking can enhance Sustainable Development Goal (SDG) analysis in capital investment. Through a review of tools, practitioner interviews, and workshops, the study identifies significant barriers in the finance sector—such as a reliance on quantitative aggregation and short-term horizons—while proposing six dimensions to operationalize systems thinking for asset managers.

This report details a project aimed at increasing energy efficiency among small and medium-sized enterprises (SMEs) in Peru. It identifies systemic barriers to energy efficiency, presents findings from a pilot study of 12 SMEs in Lima, and provides recommendations for government and private sector interventions to catalyze energy savings and support Peru's climate goals.

This policy brief describes a pilot study conducted by the Global Climate Adaptation Partnership (GCAP), the UK Met Office, and Atkins as part of the Future Climate for Africa (FCFA) programme. The study investigated the current and potential future use of medium- to long-term climate information for adaptation in Rwanda, identifying gaps in how policy-makers integrate climate projections into national planning and infrastructure projects.

This technical report evaluates water use efficiency and the application of the Alliance for Water Stewardship (AWS) standard among stone fruit farmers in the Western Cape of South Africa. It combines orchard-scale biophysical measurements of peach and plum trees with farm-scale assessments of water balance and quality across nine volunteer farms in the Breede catchment. The report finds that while Western Cape farmers are significantly more water-efficient than global averages, there are local opportunities to reduce water use by up to 20-30% through improved irrigation scheduling and the use of correct crop factors. It also details the implementation of the AWS standard, identifying drought, social risks (such as infrastructure theft), and regulatory uncertainty as primary concerns for farmers.

The York Green Neighbourhood Challenge was a community engagement project conducted from May 2009 to September 2010 in the City of York. Funded by the Without Walls Partnership Local Area Agreement (LAA) Delivery Fund, the initiative aimed to reduce household carbon emissions, raise awareness of low-carbon lifestyles, and foster community cohesion using a targeted social marketing approach.

This paper reviews data sources for fossil-fuel subsidies across countries with diverse governance systems, energy markets, and economic growth stages, specifically focusing on pilot studies conducted for China, Germany, Indonesia, and the United States.

This guide proposes the implementation of Environmental Improvement Zones (EIZs) in Winnipeg to enable neighbourhoods to develop local action plans for environmental sustainability. Based on the 'Sustainable Winnipeg' strategy, the guide outlines key environmental issues—including climate change, urban energy, land use, transportation, waste, water, and pesticides—and details pilot results from three diverse neighbourhoods: Whyte Ridge, Riverview, and West Broadway. It advocates for a shift from 'one size fits all' municipal programming toward community-based social marketing (CBSM) to foster long-term behaviour change.

This briefing by the Stockholm Environment Institute (SEI) details a pilot project evaluating the use of the SEI AI Reader, a tool based on large language models, to conduct systematic policy analysis. The project tested the tool's ability to extract data from policy evaluations and audits using a framework of 12 independent variables and 46 questions, focusing on climate policy implementation. The results indicate that with iterative prompt calibration, the AI can achieve high levels of accuracy and consistency, making it a viable method for processing large volumes of grey literature to identify drivers of successful policy outcomes.

This methodology note describes the development of Indicator 8: Embedded water risk, a supplement to SEI Working Paper No. 2016-07. The indicator uses the IOTA (Input-Output Trade Analysis) model and WRI Aqueduct data to assess the relative water risk associated with the consumption of agricultural commodities embedded in international supply chains.

This report describes two complementary methodologies developed by Transforma and the Centro Insuco para la Innovación Social (ICSI) to monitor energy communities in Colombia. While Transforma's tool focuses on longitudinal national tracking across project lifecycles, ICSI's tool provides deep socioeconomic evaluations of specific territories. The document proposes integrating these tools to bridge the gap between normative models and territorial realities.

This working paper details a pilot project to develop and implement a greenhouse gas (GHG) emissions survey tool for the Episcopal Church in the Philippines (ECP), providing a model and guide for other faith actors to measure and reduce their environmental impact.

This research paper presents a deep learning framework developed by the World Resources Institute (WRI) to forecast reservoir water volumes in India over a 90-day period to mitigate risks of water-driven power outages.
