[T]he choice we face is not between “business and usual” and climate action, but between alternative pathways of growth: one that exacerbates climate risk, and another that reduces it. The evidence presented in this report suggests that the low-carbon growth path can lead to as much prosperity as the high carbon one, especially when account is taken of its multiple other benefits: from greater energy security, to cleaner air and improved health.
This is good news, as it helps bolster the intellectual argument for action and quiet the arguments of the “it’s too expensive” crowd, which claims that the adjustments necessary to avert catastrophic climate change would be too painful for the economy to be feasible. As the report finds, when you add in all the secondary benefits of a less carbon-intensive global economy — lower healthcare costs as a result of cleaner air, for instance — the total cost to the economy of acting is actually quite small, or maybe even zero.
While the report is justifiably making news and being celebrated by environmental advocates for its findings, its important to note that the economic argument for action on climate change is not new. Environmental economists have understood for a long time that while there may be some short-run costs involved in adjusting our global economy to avoid climate change, these short-run costs are small in comparison to the much more severe climate-related costs down the line if we do nothing.
In other words, the choice between good economics and good environmental policy is the ultimate false dichotomy; the two are one and the same. Continue reading
