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]. How can regions and cities become leaders in addressing climate change? At the same time, cities are a key contributor to climate change, as urban activities are major sources of greenhouse gas emissions. [15][16] Multiple scholars approach this in different ways, but describe this "urban laboratory" environment for testing a wide variety of practices. Key Messages • Cities have a unique ability to address global climate change challenges. Cities represent a challenge and an opportunity for climate change policy. 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. 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. 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. The module will cover both how cities are affected by climate change and how cities are contributing to climate change. First, climate change is a cumulative process. With a focus on developing countries, this partnership aims to support local and national governments in urban adaptation and mitigation processes. 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. 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. The world is becoming more and more urban, and therefore cities are important actors in addressing climate change. 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.

[31], Cities play an important role in investing in climate innovation in the United States. One of the main outputs of this cooperation is an online knowledge centre which provides information on cities and climate change. The report estimates that 85% of the emissions associated with goods within a city is generated outside of that city. Cutting emissions will also reduce local pollution from industries and transport, thus improving urban air quality and the health of city dwellers.

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. Energy efficient buildings, low carbon public transport and encouraging cycling and walking are essential to cutting CO 2 emissions. More frequent rainfall, flooding, and heatwaves are likely to be among the challenges that Europe’s cities will face from climate change. This book provides a critical analysis of the role of cities in addressing climate change and the prospects for urban sustainability. 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. [11], Two international assessments have been published by the Urban Climate Change Research Network at the The Earth Institute at Columbia University. Economic damage caused by natural disasters is particularly extensive in cities and poorer inhabitants in particular are often entirely defenceless against extreme weather.

Cities consume the vast majority of global energy and are therefore major contributors of greenhouse gas emissions. [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. [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. [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). [44] The 17 SDGs take into account that action in one area will affect outcomes in other areas as well, and that development must balance social, economic and environmental sustainability. Most cities are situated near water putting them at risk from rising sea levels and storms. 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… Cities are home to half the world’s population and produce around 75% of the world’s GDP and greenhouse gas emissions. 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. 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. Authors: Allam, Zaheer, Jones, David, Thondoo, Meelan Free Preview. Cities and Climate Change Climate Policy, Economic Resilience and Urban Sustainability. 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. 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. 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. Estimates suggest that cities are responsible for 75 percent of global CO2 emissions, with transport and buildings being among the largest contributors. 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. [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. [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. Thinking and acting at a local level helps communities fight climate … [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. Building on UN-Habitat’s long experience in sustainable urban development, the Cities and Climate Change Initiative … For example, following the United States withdrawal from the Paris agreement a coalition of cities, under the banner of Mayors National Climate Action Agenda.
