Cities in different parts of the world face different, unique challenges and opportunities in the face of climate change. Cities consume the vast majority of global energy and are therefore major contributors of greenhouse gas emissions. C40 is also positioning cities as a leading force for climate action around the world, defining and amplifying their call to national governments for greater support and autonomy in creating a sustainable future.[43]. As the hubs of economic activity, cities generate the bulk of GHG emissions and are thus important to mitigation strategies. The Cities and Climate Change Project - Pilot Program for Climate Resilience of Mozambique has an objective that would remain unchanged. Choices made in cities today about long-lived urban infrastructure will determine the extent and impact of climate change, our ability to achieve emission reductions Integrated Research and Action for Development (IRADe) was designated as a Centre of Excellence (CoE) for Urban Development and Climate Change in year 2008, by the Ministry of Housing and Urban Affairs, Government of India. One of the primary mechanisms to inspire this research is the Research and Action Agenda which is being produced as one of the primary outputs of the conference. Local involvement through “climate-conscious” urban planning and management can help achieve national climate goals and minimise tradeoffs between environmental and economic priorities at local levels. population. [47] The world's cities occupy just 3 per cent of the Earth's land, but account for 60–80 per cent of energy consumption and 75 per cent of carbon emissions. [37] Created and led by cities, C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban citizens. Only with a coordinated approach and action at the global, regional, national and local levels, can success be achieved. [30] A study done of selected Himalayan cities in India and Nepal found that none of them have a robust system of water planning and governance to tackle the water challenges emerging from rapid urbanization and climate change. By 2050, more than 70% of the population – 6.4 billion people – is projected to live in urban areas. All these have costly impacts on cities' basic services, infrastructure, housing, human livelihoods and health. [45] The targets of SDG 11 include investment in public transport, creating green public spaces, and improving urban planning and management in participatory and inclusive ways. Several examples of … The Course on Planning for Climate Change in African Cities provides the foundation for understanding cities’ exposure and sensitivity to climate change, and how cities can manage these impacts in the face of growing uncertainty. [48] Thus cities are both an important cause for and solution to climate change. Cambridge Core - Climatology and Climate Change - Climate Change and Cities - edited by Cynthia Rosenzweig [40] Steering Committee members include: Accra, Bogota, Boston, Buenos Aires, Copenhagen, Dhaka, Dubai, Durban, Hong Kong, London, Los Angeles, Milan, Seattle, and Stockholm. Over 90% of all urban areas are coastal, putting most cities on Earth at risk of flooding from rising sea levels and powerful … How we live and work together in communities and cities can have a huge impact in tackling climate change. The C40 Cities Climate Leadership Group is a group of 96 cities around the world that represents one twelfth of the world's population and one quarter of the global economy. [19] Increasing attention is being paid to the important role of peri-urban areas in urban climate resilience, particularly regarding the ecosystem services that these areas provide and which are rapidly deteriorating in Sub-Saharan Africa. Yet cities, to varying extents, are also vulnerable to climate change impacts, with poor populations facing the greatest risk. 70% of cities are already dealing with the effects of climate change, and nearly all are at risk. Climate change is a global phenomenon that largely impacts urban life. Infographic In general, city dwellers live in areas most prone to the effects of climate change. Cities are also one of the most vulnerable parts of the human society to the effects of climate change, and likely one of the most important solutions for reducing the environmental impact of humans. Because they are home to major infrastructure and highly concentrated populations, cities are also vulnerable to the impacts of climate change, such as rising sea levels, warmer temperatures and fiercer storms. The SDG 11 is to "Make cities inclusive, safe, resilient and sustainable". Local involvement through “climate-conscious” urban planning and management can help achieve national climate goals and minimise tradeoffs between environmental and economic priorities at local levels. The module will cover both how cities are affected by climate change and how cities are contributing to climate change. In cooperation with partners, UNEP assists national and local governments by raising awareness, organizing workshops and trainings, developing evaluation tools and involving cities in international meetings on climate change. [12] The first of which was published in, the first of which (ARC3.1) was published in 2011,[13] and the second of which (ARC3.2) was published in 2018. The module will cover both how cities are affected by climate change and how cities are contributing to climate change. To strengthen municipal capacity for sustainable urban infrastructure provision and environmental management which enhance resiliency to … However, cities are not just drivers of climate change, they are also particularly affected by it. Legal. In addition, the module will look at how climate change adaptation and mitigation can be considered in urban planning and identify concrete measures. At the same time, cities are a key contributor to climate change, as urban activities are major sources of greenhouse gas emissions. Many cities are already doing a lot by using renewable energy sources, cleaner production techniques and regulations or incentives to limit industrial emissions. In some cities, it’ll be like moving two states south. In 2018, 4.2 billion people, or 55 percent of the world's population, lived in cities. [39] The rotating Steering Committee of C40 mayors provides strategic direction and governance. Cutting emissions will also reduce local pollution from industries and transport, thus improving urban air quality and the health of city dwellers. SDG 11: Sustainable cities and communities, Global Covenant of Mayors for Climate & Energy, CS1 maint: DOI inactive as of January 2021 (, CS1 maint: multiple names: authors list (. SDG 11 has 10 targets to be achieved, and this is being measured with 15 indicators. Inland, changes in weather patterns and extremes could threaten cities with both too much water (in the form of overland or flash flooding) and too little water (in the form of extended perio… [21] Much of this urban development is informal, with urban residents settling in informal settlements and slums often on the outskirts of cities. [25] Peri-urban ecosystems can provide functions such as controlling floods, reducing the urban heat island effect, purifying air and water, supporting food and water security, and managing waste. [26], South Asia’s urban population grew by 130 million between 2001 and 2011—more than the entire population of Japan—and is poised to rise by almost 250 million by 2030. By 2050, the urban population is expected to reach 6.5 billion. At the same time, cities are a key contributor to climate change, as urban activities are major sources of greenhouse gas emissions. [41], Working across multiple sectors and initiative areas, C40 convenes networks[42] of cities providing a suite of services in support of their efforts, including: direct technical assistance; facilitation of peer-to-peer exchange; and research, knowledge management & communications. At the same time, the exposed infrastructure and prevalent coastal location of many cities makes them common targets for climate change impacts such as sea level rise and fiercer storms. Cities, while being the main cause of climate change, are also the most affected. Opt not to print. First, climate change is a cumulative process. On Canada’s coasts, cities are vulnerable to rising sea levels, which bring with them the threat of flooding as well as more destructive storms and damaging waves [5]. More frequent rainfall, flooding, and heatwaves are likely to be among the challenges that Europe’s cities will face from climate change. If we fix cities, we can fix the world. Cities are home to half the world’s population and produce around 75% of the world’s GDP and greenhouse gas emissions. the national level can support critical urban action to combat climate change. Climate Change is one of the most pressing challenges of our times. Sustainable Development Goal 11 (SDG 11 or Global Goal 11) is about "sustainable cities and communities" and is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. Climate change is delivering a one-two punch of more severe storms and rising seas to coastal cities. The three "means of achieving" targets include: Strong national and regional development planning; implement policies for inclusion, resource efficiency and disaster risk reduction; support least developed countries in sustainable and resilient building.[44][46]. [47] Sustainable development cannot be achieved without significantly transforming the way we build and manage our urban spaces.

[15], Mayors National Climate Action Agenda, or Climate Mayors, is an association of United States mayors with the stated goal of reducing greenhouse gas emissions. Our country is well-served by this ambition. It emphasizes good governance, responsibility, leadership, and practical initiatives for local governments, communities, and citizens. [31], Cities play an important role in investing in climate innovation in the United States. A third report is being developed as of 2020. Authors: Allam, Zaheer, Jones, David, Thondoo, Meelan Free Preview. UN-Habitat’s Cities and Climate Change Initiative (CCCI) is the Agency’s flagship Initiative supporting cities in emerging and developing countries to address the climate challenge.The Initiative supports cities responding to the negative impact of climate change that is already being felt worldwide, and to put in place appropriate mitigation measures. Climate change is a uniquely complex challenge and one that will require simultaneous interventions from all levels of government. [5] Climate adaptation and mitigation investments in cities will be important in reducing the impacts of some of the largest contributors of greenhouse gas emissions: for example, increased density allows for redistribution of land use for agriculture and reforestation, improving transportation efficiencies, and greening construction (largely due to cement's outsized role in climate change and improvements in sustainable construction practices and weatherization). It contains one module which takes around 2 hours to complete. Climate change and cities are deeply connected, with cities being one of the greatest contributors to climate change. Lists of high impact climate change solutions tend to include city-focused solutions; for example, Project Drawdown recommends several major urban investments, including improved bicycle infrastructure,[6] building retrofitting,[7] district heating,[8] public transit,[9] and walkable cities as important solutions.[10]. Because of this, the international community has formed coalitions of cities (such as the C40 Cities Climate Leadership Group and ICLEI) and policy goals, such as Sustainable Development Goal 11 ("sustainable cities and communities"), to activate and focus attention on these solutions. Canadian cities, though chronically cash-starved and dramatically impacted by COVID and climate change alike, are punching well above their weight when it comes to solutions. Are you sure you want to print? Cities are being greatly affected, with more than half of the world’s population living in urban areas, of which nearly a billion in slums. Cities represent a challenge and an opportunity for climate change policy. Hence, cities have a significant influence on construction and transpo… © UNEP Terms of Use Privacy Report a project concern. Cambridge Core - Climatology and Climate Change - Climate Change and Cities - edited by Cynthia Rosenzweig It is essential, therefore, to make cities an integral part of the solution in fighting climate change. Solar power charges pandemic recovery for indigenous farmers in Viet Nam, Sustainable consumption and production policies, Building sector emissions hit record high, but low-carbon pandemic recovery can help transform sector – UN report, Halving food waste and raising climate ambition: SDG 12.3 and the Paris Agreement. Cities and Climate Change As the hubs of economic activity, cities drive the vast majority of the world’s energy use and are major contributors to global greenhouse gas emissions. Founded in 2013 in Miami, Urban Us is a venture fund focused on start-ups upgrading cities for climate change. Cities have a key role to play in addressing the global climate change challenge. [27] Despite being a water-rich zone, climate projection models suggest that by 2050, between 52–146 million people living in South Asia could face increased water scarcity due to climate change, accounting for 18% of the global population exposed to water scarcity. Rising global temperatures causes sea levels to rise, increases the number of extreme weather events such as floods, droughts and storms, and increases the spread of tropical diseases. [24] To achieve sustainable development and climate resilience in cities in Africa, and elsewhere, it is important to consider these urban-rural interlinkages. ", "Living laboratories for sustainability: Exploring the politics and epistemology of urban transition", "Urban Living Labs : Towards an Integrated Understanding of Their Key Components", "World Urbanization Prospects - Population Division - United Nations", "Africa 2063: How Cities Will Shape the Future of a Continent", "Inspiring Climate Action in African Cities: Practical Options for Resilient Pathways", "African Cities and the Development Conundrum . Cities are responsible for the climate-sensitive development of their urban areas. Based on city-level assessments of climate vulnerability or emissions, to date UN-Habitat has supported over twenty-five cities worldwide to elaborate a climate change strategy or climate action plan in order to provide for effective and well sequenced follow-on action, e.g., building the climate-resilience of the most vulnerable communities. … [20] This rapid urbanization, coupled with the many interlinked and complex challenges as a result of climate change, pose a significant barrier to Africa's sustainable development. Africa is urbanizing faster than any other continent. [12] These papers act as summaries of the scholarship for the field similar to the Intergovernmental Panel on Climate Change reports. Supreme Court weighs in on cities' climate change lawsuits. Cities and Climate Change Climate Policy, Economic Resilience and Urban Sustainability. Watch how the climate could change in these US cities by 2050. [1] Cities are also one of the most vulnerable parts of the human society to the effects of climate change,[2] and likely one of the most important solutions for reducing the environmental impact of humans. Cities consume much of the world's energy, and thus produce much of the world's greenhouse gas emissions. Building on UN-Habitat’s long experience in sustainable urban development, the Cities and Climate Change Initiative … You need to pass a quiz after the module to receive your certificate from UN-Habitat and UNITAR. This guide on climate change adaptation in cities is intended to offer mayors and other city officials, in developing countries, practical guidance on how to respond to the challenges of climate change adaptation in their cities. [29] Urban water access is particularly critical in South Asia as it remains home to more than 40% of the world’s poor (living on less than USD 1.25 per day) and 35% of the world’s undernourished. Rising global temperatures causes sea levels to rise, increases the number of extreme weather events such as floods, droughts and storms, and increases the spread of tropical diseases. Moreover, because most cities have been built on rivers or coastal areas, cities are frequently vulnerable to the subsequent effects of sea level rise, which cause coastal flooding and erosion , and those effects are deeply connected with other urban environmental problems, like subsidence and aquifer depletion. This course focuses on climate change in urban areas, covering how cities are affected by climate change, how they contribute to it, as well as how they plan for it. [11], Two international assessments have been published by the Urban Climate Change Research Network at the The Earth Institute at Columbia University. As member of the Climate Neutral Network which brings together 19 partner cities and numerous organizations, UNEP provides its expertise on environmental issues. Estimates suggest that cities are responsible for 75 percent of global CO2 emissions, with transport and buildings being among the largest contributors.

[27] But, urbanisation in South Asia is characterized by higher poverty, slums, pollution and crowding and congestion. Climate change is a global phenomenon that largely impacts urban life. Climate change and cities are deeply connected, with cities being one of the greatest contributors to climate change. Most Europeans now live in cities, so the choices we make about urban infrastructure will have a large influence on how well we cope with climate change. Our workshop “Cities and regions: Leaders in addressing climate change” illustrated how regional and city governments are increasingly initiating action on climate change and presented examples which can be an inspiration for other cities. Founded by Los Angeles mayor Eric Garcetti, former Houston mayor Annise Parker, and former Philadelphia mayor Michael Nutter, the group represents 435 cities and nearly 20% of the U.S. [1][2] More than half of the world's population is in cities, consuming a large portion of food and goods produced outside of cities. This book provides a critical analysis of the role of cities in addressing climate change and the prospects for urban sustainability. Most cities are situated near water putting them at risk from rising sea levels and storms. The contributing role of cities in accentuating the effects of climate change is increasingly demonstrated in the literature, underscoring the unsustainable models on which urban life has been made to thrive. Cities and Climate Change reveals the importance of addressing climate change across all levels of government.

The main goal of the CitiesIPCC campaign and the IPCC Co-Sponsored Cities and Climate Change Science conference was to engage the scientific community in the next frontier of research focused on the science of cities and climate change. Often local climate policies in cities, preempt larger policies pursued by the states or federal government. Climate change is one of the most challenging issues of our time. 5 Global Cities Tackling Climate Change and Inequality From sustainable urban farming to infrastructure combating floods, projects launched by these global cities are winning plaudits. Most Europeans now live in cities, so the choices we make about urban infrastructure will have a large influence on how well we cope with climate change. The seven "outcome targets" include: Safe and affordable housing, affordable and sustainable transport systems; inclusive and sustainable urbanization; protect the world's cultural and natural heritage; reduce the adverse effects of natural disasters; reduce the environmental impacts of cities; provide access to safe and inclusive green and public spaces. They often lie on coasts, rivers, deltas or mountain slopes and are thus exposed to huge risks. More frequent rainfall, flooding, and heatwaves are likely to be among the challenges that Europe’s cities will face from climate change. All of these everyday necessities are vulnerable to changes in climate. Greening cities with parks and gardens reduces CO 2 and helps cool urban areas and reduce flooding. [3] Moreover, because of processes that create climate conflict and climate refugees, city areas are expected to grow during the next several decades, stressing infrastructure and concentrating more impoverished peoples in cities.[4]. This paper argues that climate change is an urgent agenda for cities for two reasons. [32][33][34], Founded in 2014, the organization received one million dollars in start-up funding from the Clinton Global Initiative to support the founding mayors' efforts to organize cities in advance of the signing of the 2015 Paris Agreement.[35]. UN-Habitat's Cities and Climate Change Initiative (CCCI) seeks to enhance the preparedness and mitigation activities of cities in developing countries. Because of high density and effects like the urban heat island effect, weather changes due to climate change are likely to greatly effect cities, exacerbating existing problems, such as air pollution, water scarcity and heat illness in the metropolitan areas. More than half of the world's population is in cities, consuming a large portion of food and goods produced outside of cities. Cities are central to the fight against climate change, but the IPCC recently noted that many cities — and particularly those in the developing world — lack the institutional, financial and technical capacities needed to switch to low emission development paths. This report, cities and climate change: an urgent agenda focuses on three broad issues pertaining to cities and climate change. Key Messages • Cities have a unique ability to address global climate change challenges. The world is becoming more and more urban, and therefore cities are important actors in addressing climate change. While they are major contributors to climate change, they are also particularly vulnerable to its consequences. All these have costly impacts on cities' basic services, infrastructure, housing, human livelihoods and health. If we redesign our cities to be circular, regenerative and equitable, not only can we eliminate most of the impact humanity is causing globally — we also can create a future to look forward to. City life is highly dependent on services such as electrical power, drinking water, and transportation. The book will be relevant to policy makers, researchers, and others with an interest in … Cities are what we call a “leverage point” — a place in the system where positive change can have a disproportionately beneficial impact. Save the planet. [28] At least 130 million South Asians—more than the entire population of Mexico—live in informal urban settlements characterized by poor construction, insecure tenure and underserviced plots. [22] African cities are exposed to multiple climate threats including floods, drought, water stress, sea level rise, heat waves, storms and cyclones, and the related effects of food insecurity and disease outbreaks like Cholera and Malaria from floods and droughts. Also the Environment and Climate Change Outlook (ECCO) project conducted by UNEP's Division of Early Warning and Assessment (DEWA) provides a global methodology which enables sub-regional and national level authorities to conduct vulnerability and impact assessments for adaptation to climate change. The network's objective is to make the shift to a low-emissions and eventually climate neutral society. [19] It is estimated that by 2030, more than one billion Africans will live in cities. The research perspective of cities and climate change, started in the 1990s as the international community became increasingly aware of the potential impacts of climate change. [11] Urban studies scholars Michael Hebbert and Vladmir Jankovic argue that this field of research grew out of a larger body of research on the effects of urban development and living on the environment starting as early as the 1950s. For example, following the United States withdrawal from the Paris agreement a coalition of cities, under the banner of Mayors National Climate Action Agenda. Cities and Climate Change reveals the importance of addressing climate change across all levels of government. With a focus on developing countries, this partnership aims to support local and national governments in urban adaptation and mitigation processes. But cities are as vulnerable as they are powerful. Plastic packaging accounts for 50 per cent of plastic waste. In addition, the module will look at how climate change adaptation and mitigation can be considered in urban planning and identify concrete measures. One of the main outputs of this cooperation is an online knowledge centre which provides information on cities and climate change. One of these collaborations is a Joint Work Programme between UNEP, the World Bank, UN-Habitat, under the facilitating role of Cities Alliance to address cities and climate change. We’ve since expanded to New York, Los Angeles and San Francisco, and have made over 100 investments across the globe. A 2020 study of US cities found that 45 of the 100 largest cities in the U.S. had made commitments by 2017, which led to a reduction of 6% of U.S. emissions by 2020. Estimates suggest that cities are responsible for 75 percent of global CO2 emissions, with transport and buildings being among the largest contributors. Several major international communities of cities and policies have been formed to include more cities in climate action. Climate change threatens to make cities all around the world uninhabitable, prompting a level of climate action unparalleled at state and national levels. [17][16] for example the book Life After Carbon documents a number of cities which act as "urban climate innovation labratories".[18]. All three work closely with the 13-member Steering Committee, the Board of Directors[38] and professional staff. [14], Part of the reason that cities are being studied, is that cities that invest heavily in experiments of large policies, that can be adopted by larger jurisdictions (such as San Diego's advanced urban planning practices which could be applied elsewhere in the United States).
