The report puts forward a bold vision for how to transform key economics systems, making them more resilient and productive. The Commission finds that climate adaptation can produce significant economic returns: the overall rate of return on investments in improved resilience is high, with benefit-cost ratios ranging from 2:1 to 10:1, and in some cases even higher.
The analysis specifically finds that investing $1.8 trillion globally in five areas from 2020 to 2030 could generate $7.1 trillion in total net benefits. The five areas of climate adaptation the report considers are: early warning systems, climate-resilient infrastructure, improved dryland agriculture, mangrove protection, and investments in making water resources more resilient. These represent just a portion of the total investments needed and total benefits available.
Recent events have shown that climate change affects people everywhere. Furthermore, without action, millions of people will be pushed further into poverty, leading to increased conflict and instability.

Climate Proofing Urban Development
Almost 30 local practitioners from 12 cities, 10 countries and four continents accepted the invitation of Connective Cities and the city of Dortmund to a dialogue event on the topic of “Climate proofing urban development”, which took place from 3 to 5 September 2019 in Dortmund, Germany.
Climate change and the effects of more frequent climate impacts and extreme weather events such as heavy rainfall, severe thunderstorms, storms, prolonged droughts and heat waves are posing major challenges for cities around the world. In addition, climate change is a cross-cutting issue that affects all areas and departments of a city administration and therefore requires a cross-departmental approach.
Starting with an exchange of experiences on good practices and projects in the cities, implementation challenges were identified and eventually the participants developed six project ideas for six cities, which could lead to an improvement of the respective strategies and implementation plans.
The event concluded with an excursion to Lake Phoenix – a mega-project of the city of Dortmund to transform an industrial wasteland into a new vibrant area providing new housing, workplaces and recreation opportunities around an artificial lake. The transformation of the area also had positive effects on the climate of the area contributing to local climate adaptation.
Climate Protection and Air Pollution Control
Many air pollution control measures also help to protect the climate and vice versa. It is essential to use the synergies for environment and health.
The publication presents examples of various strategies and measures for clean air in municipalities and provides ideas on how these two areas can be interlinked.
Resilient Cities, Resilient Lives
“The world is more densely populated and more interconnected than ever before. From extreme weather to refugee crises, from disease pandemics to cyberattacks, today’s state of play requires new models of governance to mitigate risk and respond to challenges. Business-as-usual models of reactive planning and siloed decision-making will not generate the fundamental strength and flexibility essential for us to thrive in the face of the shocks and stresses of the 21st century. […] The launch of 100 Resilient Cities program (100RC) by the Rockefeller Foundation acknowledged that the escalating trends of urbanization, globaliza- tion, and climate change pose tremendous risks, but also offer a tremendous opportunity. This report shares 100RC’s knowledge about what it takes to catalyze an urban resilience movement.”
Heatwave Guide for Cities
"Heatwaves are deadly and their impacts are on the rise globally due to climate change. People living in urban areas are amongst the hardest hit when a heatwave occurs because these are hotter than the surrounding countryside. Along with climate change, urbanization is one of the most transformative trends of this century and the last. Over half the world now lives in urban areas and this is projected to increase to two-thirds by 2050. It is crucial that cities incorporate heat-reduction tactics such as green spaces into their plans for growth or retrofit them in built areas. […] This practical guide is designed with, and for, people working in city government to understand, reduce the risk of, and respond to, heatwaves in their cities."
The Future of Urban Consumption in a 1.5°C World
New ways of measuring the climate footprint of cities show that urban consumption is a key driver of global GHG emissions. Cities therefore have a responsibility to significantly reduce their GHG emissions. This work has mostly focused on transport, buildings, energy and waste. This report assesses the impact of urban consumption on climate breakdown and explores the type and scale of changes needed to ensure that cities reduce their GHG emissions in line with internationally agreed, climate-safe limits.

Transforming Coastal City Adaptation: From Idea to Practice
"People living in coastal cities around the world face great risks from the impacts of climate change. In the developing world, these often combine with the challenges of urban development and overcoming poverty and sharp inequalities, generating a particularly difficult set of tasks for local policy makers. Adaptation measures often focus on large infrastructural measures such as coastal defenses, at the expense of integrated and inclusive solutions that tackle not only people’s exposure to hazards, but also social vulnerabilities and their root causes. This Brief introduces three key considerations for transformative policy change that builds resilience in highly exposed coastal cities."
The Future of Cities
This report identifies challenges influencing the future of cities in Europe and beyond in fields like environmental impact, ageing, health, housing, social segregation, governance and mobility. It also presents several perspectives from which to look at resolving these issues. It is an initiative of the Joint Research Centre (JRC)i, the science and knowledge service of the European Commission (EC), supported by the Commission’s Directorate-General for Regional and Urban Policy (DG REGIO). The main aim is to raise open questions and steer discussions on what the future of cities can, and should be, both within the scientific and policymaker communities. The report benefits greatly from the collective intelligence put forward by the Members of the EC Community of Practice on Cities and is linked to aninteractive online platform, which is s designed to raise open questions and steer discussions for sharing and accumulating knowledge on the future of cities.
The 8 Principles of Sidewalks
"Walking is the most democratic way to commute. It is the oldest and most common mode of transport in the world, not to mention being a far healthier option – for both people and cities. The 8 Principles of Sidewalks systematizes the most relevant Brazilian and international references into a single publication about the planning, design and construction of sidewalks that meet the needs of people walking. The goal of this guide is to provide deeper insight into the role of sidewalks in spaces that provide opportunity for social interaction among people."
