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 […]
This document establishes common guidelines of action for all countries and priority sectors, to ensure the delivery of high quality and consistent project outputs to increase the likelihood of achieving the intended outcomes.
In this second edition of “Regulatory Barriers for ESCOs”, 19 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 […]
The adverse impacts of human-induced climate change have severe repercussions for the planet’s well-being and societies. Rising sea levels, elevated temperatures, extreme weather, and biodiversity loss are among the current global challenges. Despite commitments to mitigate and adapt to these impacts in line with the Paris Agreement, these measures may be insufficient, leading to unavoidable and sometimes irreversible loss and […]
Building on four previous publications, this publication provides a new set of success stories on how countries have used their TNAs and TAPs to advance the implementation of climate technologies. It provides examples from different regions and covers different sectors. The stories highlight how TNAs are used by developing countries as a highly practical tool that provides an effective and […]
This policy brief provides answers to two questions. First, why energy efficiency investments continue to represent a marginal share of green investment volumes, even though energy efficiency improvements are among the most prominent investment categories in green finance taxonomies. Second, what corrective actions governments can take, especially with regard to developing-country supply chains. The intended primary audiences of this document […]
Energy efficiency and nature‐based solutions can help cities combat excessive heat amid rising temperatures. Energy efficiency mitigates excessive heat, whereas nature‐based solutions adapt and withstand it. Better construction, building energy efficiency, and sustainable transportation policy, planning, and technology can help cities cope with high heat. Reduced energy consumption reduces greenhouse gas emissions and climate change. Nature‐based solutions, such as green […]
The first Global Stocktake (GST) will come to its conclusion at COP28 in Dubai, questions regarding the exact outcome of the process and how it will be translated into action remain open. Currently the GST is preparing its political component under the final phase “Consideration of Outputs”, where the focus will be discussing the implications and findings of the technical […]
Access to clean water and modern energy supply are key preconditions for modern life. Water-energy nexus refers to the tight interlinkage and high interdependence between water and energy demand and supply (WWAP, 2014). Energy production, especially hydropower and the cooling of thermal and nuclear power generation, depends on water. Reallocating water to different uses and places might increase the value […]
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 […]
