The UN Environment Programme (UNEP) today published detailed guidance to help the world's cities address warming, which is occurring at twice the global average rate in urban areas., prepared with RMI, states that by the end of this century, many cities could warm if GHG emissions continue at high levels. Even at 1.5°C of warming, 2.3 billion people could be vulnerable to severe heat waves.Launched at the ongoing UN Climate Conference (COP26) by , , , the , Mission Innovation and the , the new guide offers planners an encyclopaedia of proven options to help cool cities."Science tells us that to keep global temperatures from rising by more than 1.5°C, we need to achieve net-zero emissions by mid-century. Sustainable and equitable urban cooling must be a part of cities' efforts to reach net-zero energy targets," said Inger Andersen, UNEP Executive Director.In outlining the problem, the Sustainable Cooling Handbook for Cities describes how cities are warming quickly due to the 'heat island effect', caused by a combination of diminished green cover, the thermal properties of the materials commonly used in urban surfaces, and waste heat from human activities.The Handbook notes that:Demand for space cooling is increasing. The energy requirement for space cooling is predicted to triple from 2016 to 2050 as millions of households in developing countries acquire air conditioners in the coming decades.Impacts of urban heat are not evenly distributed. Cooler cities, homes and streets are key to ensure climate justice. Lower-income districts and communities are usually the most vulnerable to heat, placing the negative impacts of excess warming disproportionately on those least likely to be able to afford or access thermal comfort. We need to transition to more equitable and sustainable ways of cooling our cities and make them liveable for all.The benefits of sustainable urban cooling are far reaching, including improved health and productivity, reduced power energy requirements, lower emissions, and economic benefits.Cooling strategies can be optimized to work together efficiently. The report calls for a whole-system approach - that is, reduce heat at urban scale, reduce cooling needs in buildings and serve cooling needs in buildings efficiently - to benefit from integrative effects.City officials working to make their cities cooler and more liveable are faced with a wide range of approaches - the challenge is where to start."This new handbook provides a comprehensive overview of ways to cool cities sustainably and equitably," said RMI CEO Jules Kortenhorst. "Based on systems-level thinking, this handbook includes actionable guidance to help cities make progress towards sustainable and equitable urban cooling, while also cutting emissions and increasing city resilience."The guide's 80 supporting case studies and examples demonstrate the effectiveness of the strategies outlined and can help cities find an approach best suited to their unique contexts.In collaboration with the Cool Coalition, , an initiative of the , announced plans to disseminate the new Sustainable Cooling Handbook for Cities to their partner cities and counties- including Athens, Greece, Freetown, Sierra Leone, and Miami-Dade County, United States. The newly announced Athens, Freetown and Miami-Dade Chief Heat Officers will be the first to benefit from this comprehensive guide.To meet the energy- and building-related emissions target of their Nationally Determined Contribution under the Paris Climate Agreement, Vietnam will also pilot the handbook in three cities, Can Tho, Tam Ky and Dong Hoi City.Similarly, 10 Indian cities will collaborate with UNEP, , RMI and the to integrate cooling into their city masterplans.Example case studiesUnited States: Heat reduction services from urban tree cover in the United States are estimated to be worth USD 5.3 billion to USD 12.1 billion annually. Globally, investing USD 100 million annually in street trees would give 77 million people a 1°C reduction in maximum temperatures on hot days.Seoul, South Korea: An effort to restore the Cheonggyecheon stream that runs through the city replaced 5.8 kilometres of elevated expressway covering the stream with a mixed-use waterfront corridor. The waterfront corridor decreased temperature 3.3°C to 5.9°C compared to a parallel road a few blocks away.Medellin, Colombia: Green corridors were created that follow and restore the geography of the area prior to recent development. From 2016 to 2019, the city created 36 corridors, 18 along major roads and 18 along waterways, covering over 36 hectares. The areas with green corridors have already seen temperature reductions of up to 4°C.Paris, France: Paris is home of the first and largest district cooling system in Europe. When the water temperature in the Seine River that cuts through city is below 8°C, this water is used to provide "free cooling."Toronto, Canada: The municipal government implemented the largest lake-source cooling system in the world. Commissioned in 2004, Enwave's 264 MW of refrigeration Deep Lake Water Cooling (DLWC) system uses Lake Ontario's cold water as a renewable energy source.Guangzhou, China: The municipal government adopted regional centralized cooling as part of a green and environmentally friendly modern urban centre in the core area of the Pearl River New City development. The local environmental temperature in the core area of Zhujiang New Town was reduced by 2-3°C compared to using distributed cooling systems.Additional Quotes"The Global Covenant of Mayors is the world's largest alliance of cities taking action on climate, representing over 11,000 cities and one billion people. No matter how large or small a city, introducing sustainable urban cooling will both cut emissions and build resilience. We look forward to taking this handbook and sharing it across our worldwide network of cities so they can take immediate steps to make urban spaces cooler," said Andy Deacon, Acting Managing Director, Global Covenant of Mayors."Cities are at the forefront of the climate crisis, so it's vital that local governments urgently adopt sustainable urban cooling solutions to protect their communities from rapidly rising temperatures while also limiting further global warming," said Noah Horowitz, Director of the Clean Cooling Collaborative. "This guide is an invaluable tool for cities wanting to take meaningful action for both people and the planet.""I am delighted to see how Mission Innovation has brought together the community to develop the Sustainable Cooling Handbook for Cities. This is a great example of what we mean by catalyzing clean energy solutions for all. We look forward to playing a role in its deployment in the next phase," Lee McDonough, Director General, Net Zero Strategy and International, UK Representative on MI Steering Committee.This story is provided by PRNewswire.will not be responsible in any way for the content of this article.
