  • Establishing, expanding and sustainably managing urban trees and forests can unlock many important benefits for climate action, such as reducing urban temperatures by up to 8 degrees C, reducing flood and landslide risk, improving physical and mental health, creating green jobs, and contributing to biodiversity. Sixty cities have already pledged to plant over 12 million trees as part of the Trees in Cities Challenge launched by UNECE and Mayors in 2019.  



  • The Kyiv Protocol on Pollutant Release and Transfer Registers facilitates access to integrated data and information on releases of greenhouse gases and hazardous chemicals and wastes. By supporting adequate measurement, reporting and dissemination of information, implementing PRTR systems help governments and stakeholders to manage risks in production processes and throughout product lifecycles, and support the sound management of chemicals as part of climate change mitigation and adaptation measures. Results from a recent survey among Parties and stakeholders on the experiences in implementing the Protocol on Pollutant Release and Transfer Registers showed that using PRTR together with, and for, other existing reporting obligations may also improve data quality and reduce costs for its reporting, management and use. This could also facilitate analysis related to cross-cutting issues, helping to improve, for example, cooperation and coordination under the UNFCCC and Stockholm, Rotterdam and Minamata Conventions. 




  • Large scale deployment of Carbon Capture Use and Storage (CCUS) technology in the UNECE region would allow countries to decarbonise the energy sector and hard-to abate industrial sectors in the medium term to bridge the gap until next generation low-, zero-, or negative- carbon energy technologies become available. Captured CO2 can be used in a range of mineralization, chemical and biological processes, with applications in the industrial, steel, cement and chemicals sectors. In a future hydrogen economy, this captured carbon could be used to make many of the chemicals and plastics currently made using fossil fuels. UNECE-led regional cooperation can help countries scale up CCUS implementation


  • According to the UN International Resources Panel, resource extraction and processing account for half of total greenhouse gas emissions, excluding those related to land use. Adopting circular economy principles offers a unique opportunity to improve resource efficiency and decarbonize our economies. From its leading normative work to policy support and platforms for cooperation, UNECE provides a variety of tools to facilitate the widespread adoption of circular economy approaches.  


  • Cities are faced with tackling complex climate change impacts, but are also taking ambitious climate action on the ground. In a highly urbanized region – where some 75% of the population already lives in cities – UNECE’s pioneering Forum of Mayors brings together urban leaders to share concrete challenges, experiences and solutions – from sustainable mobility initiatives in Boston (USA), Gaziantep (Türkiye), Tbilisi (Georgia), Trondheim (Norway), Utrecht (Netherlands), Yerevan (Armenia), to harnessing nature-based solutions in the first climate action plan of Loulé (Portugal), and climate-neutral and energy-efficient homes in Bristol (UK), and beyond. The Forum contributes to a new, networked and inclusive multilateralism that connects local, national and regional policy dialogue to jointly address key challenges.  


  • Through the San Marino Declaration, governments in the region have agreed on a first-of-its-kind set of Principles for Sustainable and Inclusive Urban Design and Architecture, to be applied to the design of all buildings and urban developments. Climate neutrality, resource efficiency and circularity, and disaster resilience are key dimensions, where the principles offer a tool to support the crucial role of urban practitioners to achieve change on the ground. Leading architects and practitioners have signaled their readiness to translate them into action.
