Business Extra: Climate Edition - Is finance the solution?



Participants at Cop28 in Dubai are more adamant about cutting emissions this time, chief executive of Dynamic Planet Kristin Rechberger told Business Extra host Cody Combs in an interview on the sidelines of the climate summit.

Ms Rechberger said there was a greater presence of nature-preserving pavilions at this Cop than at any previous climate summit. She also talked about green finance, blue finance and the importance of climate funds.

She said her transition from being an executive at National Geographic to founding Dynamic Planet was about finding a way to restore nature and make money at the same time, and to encourage businesses to enter that realm.

Dynamic Planet was founded in 2012 to “help advance markets to restore nature” through adopting new business models. It also focuses on developing responsible business with high-impact partners that regenerate landscapes, seascapes and communities.

What is graphene?

Graphene is a single layer of carbon atoms arranged like honeycomb.

It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.

Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.

By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.

At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.

It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.

But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.

In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.
