The 100 most sustainable cities on the planet in 2022

The 100 most sustainable cities on the planet in 2022

Ranking analyzed 100 cities, in 47 countries, in environmental, social and economic criteria. São Paulo ranks 84th on the list

Since 2015, Arcadis, a consultancy and sustainable design and engineering solutions company, publishes an annual list of the most advanced cities in sustainability in the world. The Sustainable Cities Index 2022 evaluated 100 cities in 47 countries based on 51 metrics, in 26 indicators organized under the three pillars of sustainability: Planet (environmental), People (social) and Profit (economic).

“CSI 2022 offers yet another vision of prosperity that puts the planet and people at the center. Profit can – and should – be a catalyst for social and environmental well-being. Cities that cannot tap into the strength of the economy will inevitably find themselves limited in their efforts to improve the lives of their citizens or invest in the transition to sustainability,” the report says.

The Norwegian capital Oslo tops the overall index. Stockholm (Sweden), Tokyo (Japan), Copenhagen (Denmark) and Berlin (Germany) complete the top five positions on the list.

With the exception of Tokyo, the top 20 is occupied only by European and North American cities, with emphasis on the Scandinavian ones, which hold three places in the top five positions.

The best placed Brazilian in the general evaluation is São Paulo, in 84th position, which also appears at number 94 in People. Rio de Janeiro is ranked 48th in Planet and 83rd in Profit.

Oslo: the number 1

The champion Oslo ranked 1st in the Planet pillar, 17th in People and 39th in Profit. According to Arcadis, although all the pillars have a strong weight in the final classification, the Planet is the most important.

The Norwegian city of about 650,000 inhabitants has, historically, had a strong environmental concern and has intensified these efforts in recent years.

In transport, for example, since the 1990s, it has encouraged the population to use electric vehicles – today, the city is a world leader in electric mobility and intends to reach 100% of cars in 2025. At the same time, large investments are being made in public transport , bicycle infrastructure and waterways.

Waste management is another strong point. In addition to a complete selective collection service and a series of recycling programs, the municipality is the first to test carbon capture and storage through waste incineration.

“Waste management is a global challenge that currently generates huge emissions. Large volumes of waste are deposited in landfills. Recovering energy from these wastes using carbon capture is part of the solution. Norwegian knowledge can become a global export,” says Oslo Mayor Raymond Johansen.

The Norwegian capital’s climate strategy is also ambitious and establishes that Oslo will become practically free of greenhouse gas (GHG) emissions by 2030, with a 95% reduction in emissions compared to 2009 – and 52% less already in 2023.

From 2030, the project is for Oslo to be a “carbon negative city”, says the document. The intention is to contribute to reducing the amount of GHG in the atmosphere through biological means and industrial carbon capture and storage.

A 10% reduction in total energy consumption is still projected by 2030 compared to 2009. And resilience is being built to withstand the impacts of climate change expected by 2100, with adaptation measures such as green roofs and run-off spaces. Water.

Cities are the key to achieving climate goals

More than half of the world’s population lives in cities and, by 2050, this measure is projected to rise to two-thirds. In this context, Arcadis points out in the Sustainable Cities Index 2022 that, while they feed some of our biggest challenges, such as the climate crisis, metropolises can also be the solution.

“Estimates from UN Habitat indicate that while cities represent only less than 2% of the Earth’s surface, they consume 78% of the world’s energy and produce more than 60% of greenhouse gas emissions”, states the study.

However, recalls the report, it is in cities where people come together to find innovative solutions to humanity’s problems and where new paths for the future are tested and improved.
