Cities are on the frontlines of the climate crisis, and those of us who govern and live in cities already know that robust, transformational action is needed across sectors to safeguard our livelihoods and welfare. But we will not be effective if we act alone, especially if national governments do not act responsibly in leading the world in limiting global warming to 1.5°C.
As Mayor of Barcelona, Co-President of Metropolis and Vice Chair of C40 Cities — a network of nearly 100 cities around the world confronting the climate crisis — , I firmly believe in the power of cities working together in the public interest. In 2020, I told Metropolis about how coordination between cities in the Barcelona Metropolitan Area (AMB) helped us protect residents early in the Covid-19 pandemic — we were able to close beaches along the coastline to limit the spread of the virus and present a united front to our residents in uncertain times.
As urban areas are home to a majority of the world’s population, city leaders around the world have the opportunity to work together to advance towards common goals on the future we want for our cities.
Such collaboration between cities is key in times of crisis, and the climate crisis is no different. As urban areas are home to a majority of the world’s population, city leaders around the world have the opportunity to work together to advance towards common goals on the future we want for our cities. This includes prioritising climate justice, meaning that as we address the changing climate we must generate co-benefits for the most disadvantaged members of the population.
In Barcelona, I have been proud of the actions our city has taken to prioritise equity-led climate programmes. By reclaiming streets for people rather than cars through our Superblock project, we are lowering vehicle emissions that pollute the air and harm residents unequally, while providing more green space within our communities and improving public transportation and sustainable mobility. We have boosted refurbishment programmes to achieve energy independence, and we have also expanded our network of Climate Shelters to protect our residents from the often-deadly effects of heatwaves in 2021. And, in addition to initiating innovative programmes to build a better Barcelona, we are challenging the economic model at the foundation of the climate crisis.
The sum of the actions taken by Barcelona and other cities around the world, from Beijing, to Jakarta, to Accra, contribute to the fight against climate change on a global scale. For example:
- Cape Town’s push to retrofit ceilings in more than 10,500 homes in low-income communities is estimated to save approximately 7,400 tonnes of CO2 each year.
- Efforts to restore more than 200 public ponds in Chennai are boosting biodiversity in addition to preventing an estimated 420 kg of CO2 emissions.
- Seoul is also one of several global cities to pursue its zero-carbon and equity goals through a Green New Deal.
- In an impressive example of cross-city collaboration, my colleagues in Cape Town, Durban, Ekurhuleni, Johannesburg and Tshwane are also working together to develop innovative approaches to inclusive climate action.
As COP26 approaches, we are truly at a crossroads for humanity. Cities must be on the path to limit global warming to 1.5°C and prioritise a Green and Just Recovery from the Covid-19 pandemic. By coming together as the largest ever coalition of local governments leading the charge to COP26, we can send national governments a resounding signal that cities are united in meeting the Paris Agreement goals and in creating a more inclusive and resilient economy. Cities Race to Zero presents an opportunity to meet this once-in-a-generation moment. This coalition is made up of cities setting science-based targets and committing to inclusive and resilient climate action to get our cities to net-zero carbon emissions, a landmark that is crucial to prevent the worst effects of climate change.
Just think what thousands of cities around the world — large and small — can accomplish together
Just think what thousands of cities around the world — large and small — can accomplish together. Thank you to those of you who have already committed to the Race to Zero, but there is still more to be done to reach our goal of getting a critical mass of cities to commit to tangible climate action. This is the last chance to join this group of city leaders and send a resounding message to our residents and national governments that we, the mayors of the world’s cities, are serious in the fight against the climate crisis.
If you are ready to commit, join Cities Race to Zero today.
