There is a growing push from some businesses to protect the climate and nature, but more action is needed � businesses, governments and philanthropy all play a crucial role in mitigating these financial risks, writes UNSW Canberra's Dr Megan Evans For many businesses, climate change is an existential threat. Extreme weather can disrupt operations and supply chains, spelling disaster for both small vendors and global corporations. It also leaves investment firms dangerously exposed. Businesses increasingly recognise climate change as a significant financial risk. Awareness of nature-related financial risks, such as biodiversity loss, is still emerging. My work examines the growth of private sector investment in biodiversity and natural capital. I believe now is a good time to consider questions such as: what are businesses doing, and not doing, about climate change and environmental destruction? And what role should government play?
