$50 billion is the current projected cost to replace the Australian submarine fleet.
$60 billion is roughly 5% of Australia’s GDP
$96 billion is what 9.3 million Australian households spend on the modern equivalent of bread and water, somewhere near 15% of their weekly budget. This is a pretty standard proportional spend in mature economies. Somewhere between 7 and 15% of household budgets go to food. The French at the higher end, the British the lower.
Big numbers then.
$226 billion is an order of magnitude larger. It represents the size of the labelled green bond market in 2016.
$895 billion is the size of the climate-aligned blond universe. This amount includes investments that are designed to support climate adaptation or have an impact on emissions but are not quite up for a green label.
$1,000 billion is the projected size of the climate aligned bond market in 2020, just three years hence, investments that are needed to help all countries meet their Paris climate commitments for emission reduction.
$90,000 billion is the current size of the global bond market.
The interesting question is where to put all this money.
It makes sense to put a hefty chunk of it into actions that improve environmental performance or, alternatively, new submarines.
