Steel is the backbone of modern society, and it’s also responsible for 7% of global greenhouse-gas emissions every year. This summer, Bloomberg Green reporter Akshat Rathi visited a US startup that says they can clean it all up. Operating in a suburban office park in Colorado, Electra is coming out of stealth mode. It claims to have developed a way to get through the most energy-intensive part of steelmaking at temperatures lower than fresh coffee. Akshat dives into the science and story of Electra with CEO Sandeep Nijhawan.

Zero is about the tactics and technologies taking us to a world of zero emissions. Each week Bloomberg’s award-winning reporter Akshat Rathi talks to the people tackling climate change – a venture capitalist hunting for the best cleantech investment, scientists starting companies, politicians who have successfully created climate laws, and CEOs who have completely transformed their businesses. The road to zero emissions has many paths and everyone’s got an opinion about the best route. Listen in.

How can music be used to communicate the climate crisis and its solutions? This week on Zero, Akshat Rathi talks with Pulitzer Prize winning composer Julia Wolfe about her recent work, unEarth, which explores climate change and habitat loss through orchestra, voice and poetry. Wolfe discusses how she did her research, captured the clash between humanity and nature, and what the piece means at a time when her home country of the US seems to be moving ever further from climate action. 

Listen to unEarth:

If you'd like to listen to the full performance of Julia Wolfe’s unEarth, it will be broadcast on BBC Radio 3 on Thursday, 12 February at 7.30pm UK time, and will be available on BBC Sounds, at least for those here in the UK, for the next month.
