Thanksgiving and the pseudo-holiday Black Friday are as good a time as any to reflect on the role overconsumption and waste play in the climate crisis. We don’t typically focus on personal carbon footprints in this newsletter, which tend to be a distraction from bigger systemic problems that matter more. But the month between now and the New Year presents a lot of opportunities for holiday shoppers and home chefs to make more sustainable choices and think more broadly about individual responsibility, especially at a time when the US government is about to take a big step back from its role in regulating emissions. The stats from this weekend’s holidays are sobering: About 316 million pounds of food will be wasted on Thanksgiving day in the US, with a carbon footprint equal to driving 200,000 cars for a year. In Europe, researchers estimate that Black Friday online shopping leads to a 94% spike in shipping-related emissions compared to an average week, in part because an above-average share of purchases on these consumer “holidays” are returned. What I take away from those numbers is that the best way to help is to just buy less stuff. It will always be hard to pin down the quantifiable carbon impact of one avoided purchase of a turkey or TV. A more useful way to think of the problem is in reverse: The average person in the US is responsible for about 14 tons of CO2 per year, among the highest rates in the world. China, which Western politicians love to accuse of killing the climate, emits about half that rate. India is closer to 2 tons. Samoa, whose climate envoy led a walkout during COP29 to protest the paltry financial support his country has received, is close to 1 ton. If you’re a person in the US, there are some elements of this sum that are hard for an individual to change. You can’t snap your fingers and close a coal plant. Not everyone can afford an EV. But buying less is an option available to everyone, and sends a signal to the market that’s at least as impactful as the one sent by buying “greener” stuff. It’s the cheapest and easiest way to cut back on those 14 tons. Nobody needs to (or should) live like a cave-dwelling monk to fight climate change. But we’re entering a time of year in Western culture that proactively celebrates overconsumption. I think it’s possible — and necessary — to maintain the spirit of festivity with fewer garbage bags and return labels. |
