Earlier this summer, a paper published in the journal Nature captured headlines with a rather bleak forecast. Our chances of keeping global warming below the 2C danger threshold are very, very small: only about 5%. The reason, according to the paper’s authors, is that the cuts we’re making to greenhouse gas emissions are being cancelled out by economic growth.
In the coming decades, we’ll be able to reduce the carbon intensity of the global economy by about 1.9% per year, if we make heavy investments in clean energy and efficient technology. That’s a lot. But as long as the economy keeps growing by more than that, total emissions are still going to rise. Right now we’re ratcheting up global GDP by 3% per year, which means we’re headed for trouble.

If we want to have any hope of averting catastrophe, we’re going to have to do something about our addiction to growth. This is tricky, because GDP growth is the main policy objective of virtually every government on the planet. It lies at the heart of everything we’ve been told to believe about how the economy should work: that GDP growth is good, that it’s essential to progress, and that if we want to improve human wellbeing and eradicate poverty around the world, we need more of it. It’s a powerful narrative. But is it true?
Costa Rica is the most efficient economy on earth: it produces high standards of living with low GDP and minimal pressure on the environment. After all, once we have excellent healthcare, education, and affordable housing, what will endlessly more income growth gain us? Maybe bigger TVs, flashier cars, and expensive holidays. But not more happiness, or stronger communities, or more time with our families and friends. Not more peace or more stability, fresher air or cleaner rivers. Past a certain point, GDP gains us nothing when it comes to what really matters. In an age of climate change, where the pursuit of ever more GDP is actively dangerous, we need a different approach.
