So I was over there as a guest of the then climate change Minister, the Hon Tim Groser, but of course because I was in Opposition I wasn't involved directly in the negotiations. I went along to the launch of the Task Force on Climate-related Financial Disclosures, which was chaired by Michael Bloomberg and Mark Carney, who was then, of course, the Governor of the Bank of England. These two gentlemen are particularly dry, economically, You could not accuse either of them of being radical hippies in any sense, but the language that they were using really was sounding the alarm, and there was a key phrase that I think Mark Carney used. He said that in their assessment, in the assessment of that task force, there are literally of trillions of dollars of unquantified, undisclosed and therefore unmanaged risk sitting on corporate balance sheets as a result of climate change—trillions of dollars of risk that is not known about by the directors or the shareholders of those businesses, and of course that represents a material risk to those businesses themselves. It represents a material risk to the owners of those businesses. Actually, it's so wide scale it also represents a risk to the financial system itself, which is why central banks like the Bank of England are so interested in supporting this climate-related financial disclosures regime and why our own central bank, the Reserve Bank, was so keen for us to adopt this legislation.
