Climate change has been the number one topic for discussion this week at the World Economic Forum in Davos. 

Dr Marco Lambertini, Director General at the World Wildlife Fund for Nature (WWF), said the global business sector is responsible for the majority of the world's carbon footprint.

Dr Lambertini said the WWF attends Davos every year so as it can talk to business leaders and drive the sustainability agenda so that business can go from being the problem to being part of the solution.

He said while some would say that progress on climate change is not moving fast enough, he welcomed the new clarity about the direction in which it should be going as well as the growing sense of urgency among businesses.

This needs to be replicated for nature including the world's oceans and biodiversity, Dr Lambertini urges, adding that a new deal is needed for nature as much as a new deal for climate change as agreed in Paris. 

Responding to the Global Risks report last week, the WWF Director General said the science around climate change has never been clearer and awareness has never been greater, while the response to the challenges has also never been so high.

He also said that biodiversity loss is among the top concerns in the Global Risks report for the first time as people realise that if the oceans collapse and forests disappear we are undermining the stability of the planet on which both business and society depend.

"That is a major wakeup call for the business sector," he added.
