This policy note provides a summary and perspectives of the Water-Energy-Food-Ecosystems (WEFE) Nexus for climate-resilient sustainable development. It showcases the strong inter-relationship between water resources, energy generation, food production and freshwater ecosystems and the links between the WEFE nexus and integrated water resources management (IWRM). The WEFE nexus emphasizes using a systems approach to give equal consideration to all four […]
In the pursuit of sustainable development and climate resilience, off-grid solar electric cooking (e-cooking) technologies is a dual solution encompassing both climate change mitigation and adaptation strategies. Globally, cooking with biomass amounts for as much as 2% of CO2 emissions. Given the rapid advances and price reductions in solar e-cooking technologies, there is an opportunity to scale these solutions to […]
In this third edition of “Regulatory Barriers for ESCOs”, 25 ESCO associations have provided comprehensive answers to 15 questions that illuminate different aspects of regulatory barriers for ESCOs. The formulation of the questions was informed and inspired by interviews that were conducted in 2021 for the first edition of this publication, where focused interviews with 10 ESCO associations served as […]
This report was developed in support of the 2024 Emissions Gap Report (EGR) of UNEP. It provides the analysis and findings that are used as background for the development of Chapter 6 of the EGR 2024: “Bridging the gap: Sectoral transformations, benchmarks, potentials, and needed investments”. The report addresses two critical questions: can the emissions gap identified for 2030 and […]
Since the establishment of the first global agreement to limit greenhouse gas emissions – the Kyoto Protocol – the idea of trading in emissions units, or emissions reduction, has been an essential part of the architecture, motivated by calculations showing that costs of emissions mitigation vary widely among countries. So why not exploit the more cost-efficient mitigation options first if […]
Over time and through an iterative process, collective learnings and practical insights from the global- and country- level work on TNAs have informed and enriched the TNA methodology, including through growing guidance3 available to countries and implementation actors. Today, the TNA process has evolved into a step-by-step process that goes beyond technology needs and is geared towards enabling technology implementation […]
The UNEP Adaptation Gap Report provides an annual science-based assessment of the global progress on adaptation planning, financing, and implementation. It also explores options for enhancing and advancing national and global adaptation efforts and provides an in-depth analysis of selected issues of interest. In addition to the update on adaptation planning and implementation, the 2023 edition provides a more in-depth […]
This publication, a product of the Adaptation Working Group of the independent Global Stocktake (iGST), aims to advance conceptual and operational discussions of the A&E of adaptation in the context of the GST by bringing together the perspectives of a multitude of stakeholders, including academia, practitioners and policy-makers, all organized around one fundamental question: ‘How can the concepts of adequacy […]
The development, transfer, diffusion, and uptake of technologies to mitigate and adapt to the impacts of climate change are essential to the response to the rapidly escalating problem of climate change. However, while the role of technologies is increasingly recognized, the degree to which technologies are deployed and barriers and enabling conditions for the development, transfer, diffusion, and uptake of […]
