Experts at the World Economic Forum release yearly updates assessing the biggest dangers facing the world economy. Environmental concerns have jumped up the list and now global warming tops economists’ concerns.

Last month I attended an Australian Credit Conference hosted by a large global credit rating agency. The event was well represented by investors and large business organisations. With a number of questions put to the audience, everyone had an opportunity to vote on the topics offered. The popular choice was along the lines of: “What do you think is the biggest threat to the Australian economy today, the cost of carbon reduction or the environmental issues associated with greenhouse gas pollution?”

At the risk of being controversial, it was shocking to me that the business community, as represented at the event, thought changing our (dirty) energy habits would be more disastrous economically than climate change. I was quite surprised that the majority of attendees felt our biggest economic threat is the effect of carbon reduction measures. Surprised, because I assumed those in attendance to be well-informed people with access to plentiful resources about current environmental concerns.

While our business leaders need a crash course in environmental awareness – I’d like them to sit through Al Gore’s An Inconvenient Truth or a screening of Leonardo DiCaprio’s documentary, Before the Flood – I was left wondering whether the majority of Australians in the world @work can see the effects of climate change as it is happening right now? Polls show increasing support from people at grass roots level on a range of environmental issues, including a carbon tax and green energy, but change begins with positive leadership, agitation and support from the community at large.

The potential cost of doing nothing to halt the damage to our planet is incalculable. However, it seems obvious that funding for renewables and other innovative carbon reduction energy solutions is being stalled by vested interests. It took a tweet from Tesla’s Elon Musk (who has famously offered to solve South Australia’s power problems with battery technology in 100 days) to fire-up the State Government and engage the Federal Government in the conversation. It was encouraging to see expressions of interest from local competitors in the battery market, but it’s going to take more than an ex Vice President, a Hollywood actor and an entrepreneur to kick-start a (much needed) renewables boom.

The World Economic Forum says failing to mitigate climate change will likely have a bigger impact globally than the spread of weapons of mass destruction, mass involuntary migration, predicted water crises and a severe energy price shock – Australian consumers have experienced significant energy cost increases year on year, abolishing the Clean Energy Act notwithstanding. Instead of funding massive foreign owned coal mines, as the Queensland Government-Adani partnership proposes, or championing newer but less responsible energy sources, such as coal-seam gas (fracking was recently banned in Victoria), let’s invest in the industries where local businesses and communities also have a future. I’d love to see our manufacturers of solar panels, wind farms, battery cells and other alternative innovations receive most of those investment dollars.
