C40 Cities presents ‘Our Last, Big Chance: Why our future depends on action taken today in the world’s cities’, an in-person and virtual event which took place on 2 November 2021 at Glasgow City Chambers

Featuring mayors and thought leaders from around the world, Our Last, Big Chance showcased how we can achieve a sustainable and equitable recovery from the COVID-19 pandemic and advance C40’s vision of a just, green future.

In a time of multiple global crises, the world’s mayors have been providing the bold vision and political leadership that this moment requires – by taking groundbreaking, collaborative and urgent action. Mayors and the cities they lead are on track to hit emissions reduction targets, and alongside a coalition including civil society groups, business, labour unions and activists are delivering health benefits, creating jobs and tackling systemic inequality. 

Showcasing tangible climate actions and their benefits at COP26 is vitally important to bring all actors – including national governments and the international finance community – on board to deliver the necessary action to scale back the climate crisis.

This event also showcased DK2020, a programme led by Realdania that builds on C40’s Deadline 2020 initiative, to scale up climate action planning in all cities – large and small – in Denmark. The success of this programme could provide inspiration to other countries and municipalities in developing a similar model.

Introducing the event and welcoming the host city to the stage was our master of ceremonies Edie Lush, an award-winning journalist.
