The costs of preventing climate change are so high it will ruin our economy.


Truth: The potential cost of preventing climate change is high however, it pales into insignificance when compared with the cost of taking no action. A recent report by Lord Stern, and his fellow advisers, found the cost of not tackling climate change was between 5% - 20% of global GDP. Comparitively, the cost of limiting the worst aspects of climate change are lower than 1% of global GDP.
