COVID-19 caused the biggest drop in carbon emissions ever – how do we make it last?

In this episode of The Conversation Weekly podcast we drill down into the impact coronavirus lockdowns had on global carbon emissions – and ask what this means for the fight against climate change as governments turn their focus on the recovery. And we hear how the pandemic exacerbated the hardships faced by migrant workers in Canada. 

Corinne Le Quéré, Professor of Climate Change Science at the University of East Anglia, tells globla carbon emissions dropped 7% in 2020 – by 2.6 billion tonnes. While this was the biggest drop ever, everything is relative. She puts the figures into perspective for us about what was happening before the pandemic, and what needs to happen now for the world to reach its targets under the Paris Agreement.

And we also talk to Steve Westlake, a PhD researcher at Cardiff University, about his research into what influences our behaviour when it comes to reducing carbon emissions -- and why he thinks individual actions still matter.

We’re also joined in this episode by The Conversation’s Vinita Srivastava, host of Don’t Call Me Resilient, a new podcast about race. She introduces a conversation she had with Min Sook Lee, Assistant Professor in Documentary Film at OCAD University in Toronto, on the harsh conditions, isolation and precarious working conditions faced by migrant farm workers in Canada.

And Wale Fatade from The Conversation in Lagos, Nigeria, gives us some recommended reading.
