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. 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. [27] But, urbanisation in South Asia is characterized by higher poverty, slums, pollution and crowding and congestion. In addition, the module will look at how climate change adaptation and mitigation can be considered in urban planning and identify concrete measures. 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. Climate change and cities are deeply connected, with cities being one of the greatest contributors to climate change. Founded in 2013 in Miami, Urban Us is a venture fund focused on start-ups upgrading cities for climate change. Authors: Allam, Zaheer, Jones, David, Thondoo, Meelan Free Preview. Many cities are already doing a lot by using renewable energy sources, cleaner production techniques and regulations or incentives to limit industrial emissions. For example, following the United States withdrawal from the Paris agreement a coalition of cities, under the banner of Mayors National Climate Action Agenda. This paper argues that climate change is an urgent agenda for cities for two reasons. In 2018, 4.2 billion people, or 55 percent of the world's population, lived in cities. A report by the C40 Cities Climate Leadership Group described consumption based emissions as having significantly more impact than production-based emissions within cities. Climate change is a global phenomenon that largely impacts urban life. [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. Cities, while being the main cause of climate change, are also the most affected. A third report is being developed as of 2020. United Nations (2017) Resolution adopted by the General Assembly on 6 July 2017, United Nations Economic and Social Council (2020), concentrating more impoverished peoples in cities, largely due to cement's outsized role in climate change, Intergovernmental Panel on Climate Change, United States withdrawal from the Paris agreement, Learn how and when to remove this template message, "Climate change and cities: a prime source of problems, yet key to a solution", "Cities: a 'cause of and solution to' climate change", "Summary for Urban Policymakers – What the IPCC Special Report on 1.5C Means for Cities", "With people crowding into urban areas, how can cities protect themselves against climate change? At the same time, cities are a key contributor to climate change, as urban activities are major sources of greenhouse gas emissions. Only with a coordinated approach and action at the global, regional, national and local levels, can success be achieved. Cities are what we call a “leverage point” — a place in the system where positive change can have a disproportionately beneficial impact. More frequent rainfall, flooding, and heatwaves are likely to be among the challenges that Europe’s cities will face from climate change. Climate change is a uniquely complex challenge and one that will require simultaneous interventions from all levels of government. 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. 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. 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]. Climate change and cities are deeply connected, with cities being one of the greatest contributors to climate change. 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. Cities and Climate Change reveals the importance of addressing climate change across all levels of government. [17][16] for example the book Life After Carbon documents a number of cities which act as "urban climate innovation labratories".[18]. 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. In addition, the module will look at how climate change adaptation and mitigation can be considered in urban planning and identify concrete measures. The report estimates that 85% of the emissions associated with goods within a city is generated outside of that city. 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. 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. 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. 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]. Africa is urbanizing faster than any other continent. Cities and Climate Change Climate Policy, Economic Resilience and Urban Sustainability. It contains one module which takes around 2 hours to complete. population. 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. 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. Cities are home to half the world’s population and produce around 75% of the world’s GDP and greenhouse gas emissions.

Cambridge Core - Climatology and Climate Change - Climate Change and Cities - edited by Cynthia Rosenzweig As of 2019, Mayor of Los Angeles Eric Garcetti serves as the C40's Chairperson, former Mayor of New York City Michael R. Bloomberg as President of the Board, and Mark Watts as Executive Director. All three work closely with the 13-member Steering Committee, the Board of Directors[38] and professional staff. Cities and Climate Change reveals the importance of addressing climate change across all levels of government. You need to pass a quiz after the module to receive your certificate from UN-Habitat and UNITAR. [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]. More than half of the world's population is in cities, consuming a large portion of food and goods produced outside of cities. Climate change is delivering a one-two punch of more severe storms and rising seas to coastal cities. Estimates suggest that cities are responsible for 75 percent of global CO2 emissions, with transport and buildings being among the largest contributors. One of the main outputs of this cooperation is an online knowledge centre which provides information on cities and climate change. [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. [24] To achieve sustainable development and climate resilience in cities in Africa, and elsewhere, it is important to consider these urban-rural interlinkages. Over 90% of all urban areas are coastal, putting most cities on Earth at risk of flooding from rising sea levels and powerful … They often lie on coasts, rivers, deltas or mountain slopes and are thus exposed to huge risks. However, cities are not just drivers of climate change, they are also particularly affected by it. 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… 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. [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. 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. In some cities, it’ll be like moving two states south. It does so by introducing the basic concepts of urban resilience and adaptation, by using illustrative case studies in different African cities. By 2050, between 65% … The module will cover both how cities are affected by climate change and how cities are contributing to climate change. [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). 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. Climate change is one of the most challenging issues of our time. © UNEP Terms of Use Privacy Report a project concern. It is essential, therefore, to make cities an integral part of the solution in fighting climate change. As key sites in the production and management of emissions of greenhouse gases, cities will be crucial for the implementation of international agreements and national policies on climate change. [21] Much of this urban development is informal, with urban residents settling in informal settlements and slums often on the outskirts of cities. By 2050, more than 70% of the population – 6.4 billion people – is projected to live in urban areas. Estimates suggest that cities are responsible for 75 percent of global CO2 emissions, with transport and buildings being among the largest contributors. [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. [40] Steering Committee members include: Accra, Bogota, Boston, Buenos Aires, Copenhagen, Dhaka, Dubai, Durban, Hong Kong, London, Los Angeles, Milan, Seattle, and Stockholm. [3] Hence, cities have a significant influence on construction and transportation—two of the key contributors to global warming emissions. [48] Thus cities are both an important cause for and solution to climate change. Energy efficient buildings, low carbon public transport and encouraging cycling and walking are essential to cutting CO 2 emissions. Cities are responsible for the climate-sensitive development of their urban areas. At the same time, cities are a key contributor to climate change, as urban activities are major sources of greenhouse gas emissions. Cutting emissions will also reduce local pollution from industries and transport, thus improving urban air quality and the health of city dwellers.

[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. [11], Two international assessments have been published by the Urban Climate Change Research Network at the The Earth Institute at Columbia University. [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. [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. How we live and work together in communities and cities can have a huge impact in tackling climate change. [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. The module will cover both how cities are affected by climate change and how cities are contributing to climate change. Cities have a key role to play in addressing the global climate change challenge. Watch how the climate could change in these US cities by 2050. Opt not to print. 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. [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). [15][16] Multiple scholars approach this in different ways, but describe this "urban laboratory" environment for testing a wide variety of practices. the national level can support critical urban action to combat climate change. ", "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 .
