A New Year’s Climate Diet A New Year’s Climate Diet
(32 minutes later)
Most diets fail. They fail mostly because after a period of bingeing (for example, last night) we set unrealistic goals for ourselves to radically reform our bad ways. In time, self-control breaks down and we hunger to throw open the cupboards and binge again. Most diets fail.

The same is true of the American carbon diet. After a period of bingeing (say, the last century), the United States is per capita the most prodigious emitter of carbon dioxide among the world’s top 10 economies. The average American generated around 15 metric tons of carbon per person per year in 2016, according to the International Energy Agency, using what it says is the most recent data available. Svelte France, by comparison, weighed in at a per capita 4.5 tons, while India put out just 1.6 tons per person per year.The same is true of the American carbon diet.

To bring the planet to climate equilibrium would require a global per capita goal that falls halfway between France’s and India’s outputs at three metric tons by 2050, according to a United Nations report from 2011. All of this may make the conscientious American want to drive the family SUV into the nearest body of water and subsist on locally sourced radishes. But I am fairly certain that as with food regimens, an extreme carbon diet will falter, and practitioners will soon retrieve their SUVs and cheat so often with hamburgers that those locally sourced radishes will molder in the vegetable crisper.To bring the planet to climate equilibrium would require a global per capita goal that falls halfway between France’s and India’s outputs at three metric tons by 2050, according to a United Nations report from 2011.

But some diets do work. Effective diets tend to be modest in their goals, incorporating subtle changes paced out over long periods. That we need to radically transform the roots of our economy is unquestionable and something that must be fought for with intense social and political commitment. But inertia abounds. Not every well-meaning American will engage in a protracted political struggle. Fortunately for carbon couch potatoes, there are smaller maintainable changes that would allow many of us to go from carbon obese to just carbon overweight.But some diets do work.

Here then is something of a grocery list for the politically inert, things that can be done without a whole lot of effort that will lead to a carbon-slimmer 2020:Here then is something of a grocery list for the politically inert, things that can be done without a whole lot of effort that will lead to a carbon-slimmer 2020:
Have the chicken. Much has been made about the climate benefits of going vegan. If we switched to a vegan diet, we could cut our carbon dioxide emissions between 0.3 to 1.6 metric tons per person per year. I have made this change, but I doubt I could persuade a large portion the country to choose pea protein over pot roast even when packaged as Beyond or Impossible meat. For the legume-averse, chicken is relatively low impact. According to a study published by the nonprofit Environmental Working Group, beef can cost more than 27 kilograms of carbon dioxide per kilogram of meat eaten (much, much more if you compare foods based on protein content per unit of weight). A kilo of chicken, however, costs the planet about 6.9 kilograms of carbon dioxide. True, it’s not tofu (2.0) or lentils (0.9), but most red-blooded Americans know how to cook it.Have the chicken.

Or the fish. Fish and shellfish can make for surprisingly carbon dioxide-light meals, though not everything from the sea shrinks one’s emissions waistline. America’s favorite seafood, shrimp, can far exceed chicken and even rival pork. At the same time, a kilogram of most American-caught finfish comes in at a tofu-besting 1.6 kilograms of carbon dioxide emissions. And depending on how you adjust for nutrient content, some varieties of farmed mussels can cost us just 0.6 kilograms of carbon per kilogram of mussel meat. Take that, lentil!Or the fish.

Do nothing better. Busy Americans fret about actually having to do something to address the climate crisis in their already hectic lives. But doing nothing better can add up to something. A 2018 study in the journal Nature notes that tourism accounts for about 8 percent of global greenhouse gas emissions. Just one long-haul flight emits around a half-ton of carbon per person or a full ton of greenhouse effect if one considers other gasses a jet puts into the upper atmosphere. Business and first-class air travel generates three to four tons of carbon per long haul flight because of the excessive space those fancier seats take up. So doing nothing at home for your next vacation is an easy choice. Other better nothings include turning off your car rather than letting the engine idle, which accounts for about 30 million metric tons of carbon dioxide emissions in the United States a year.Do nothing better.

Change the way other things in your life do nothing. Similarly when your appliances do nothing, they are often burning fossil fuels. Standby power accounts for 4.6 percent of residential carbon emissions. Address this by turning off your internet router at night, shutting down your computer fully, unplugging your cellphone when it’s fully charged and choosing appliances that have low standby power requirements. To go beyond saving standby power, Karl Coplan, the author of “Live Sustainably Now,” suggests “depriving fossil fuel companies of their sales revenues by switching to a renewable-electricity contract and upgrading to an electric car the next chance you get.”Change the way other things in your life do nothing.

Be really lazy and drink from the tap. What could be a lazier thing to do than shuffling to your own sink and pouring yourself a glass of water? And yet nowadays we often replace this most low-effort of American habits with driving to a store and buying a plastic bottle of water. This can end up costing us significantly more in carbon dioxide emissions as drinking water from the tap, according to one 2009 Italian scientific analysis.Be really lazy and drink from the tap.

Ditch the car one day a week. Collectively Americans drive more than three trillion miles annually. (Over ten years that would take us all the way to Alpha Centauri, the closest star system to Earth.) That comes out to about 4.6 tons of carbon per vehicle a year, according to the Environmental Protection Agency. Transportation is the largest single contributor to American CO2 emissions, the agency says. So skipping a day of driving each week would significantly decrease an individual's per capita contribution to emissions.Ditch the car one day a week.

Upgrade a forest instead of your phone. A smartphone does not carry a huge carbon burden. Apple reports that a single iPhone 11 results in the emission of about 70 kilograms of carbon dioxide emissions over its life cycle. But if you repurposed the several hundred dollars you typically spent on a phone upgrade and donated those funds to a program managing a carbon sequestering ecosystem, you could shave a much greater portion of carbon from your budget. For the best possible carbon sink, consider the mangrove. Mangrove forests are one of the world’s most powerful carbon sinks; those in the Amazon store twice as much carbon per acre as the region’s rain forests.Upgrade a forest instead of your phone.

Make a personal divestment from fossil fuels All of us are implicated in the carbon economy through our daily financial transactions. The title of a recent New Yorker essay by the climate activist Bill McKibben read, “Money Is the Oxygen on Which the Fire of Global Warning Burns.” How to address this? “Switching to a fossil-free index fund is a no-brainer — among other things they’re outperforming the market,” Mr. McKibben wrote me recently. For those who don’t invest but do own a credit card and a bank account, Mr. McKibben suggested going a step further. “As we approach Earth Day at 50, cut up your Chase card or move your money to a new bank — JPMorgan Chase has become by far the largest funder of the fossil fuel industry.”Make a personal divestment from fossil fuels All of us are implicated in the carbon economy through our daily financial transactions.
