“Useful and relevant. . . . Greenberg’s writing is clear and concise. Each section starts with easy tips . . . then wades into bigger, trickier concepts.” —New York Times Book Review

A celebrated writer on food and sustainability offers fifty straightforward, impactful rules for climate-friendly living

We all understand just how dire the circumstances facing our planet are and that we all need to do our part to stem the tide of climate change. When we look in the mirror, we can admit that we desperately need to go on a climate diet. But the task of cutting down our carbon emissions feels overwhelming and the discipline required hard to summon. With The Climate Diet, award-winning food and environmental writer Paul Greenberg offers us the practical, accessible guide we all need. It contains fifty achievable steps we can take to live our daily lives in a way that’s friendlier to the planet–from what we eat, how we live at home, how we travel, and how we lobby businesses and elected officials to do the right thing. Chock-full of simple yet revelatory guidance, The Climate Diet empowers us to cast aside feelings of helplessness and start making positive changes for the good of our planet.“Useful and relevant. . . . Greenberg’s writing is clear and concise. Each section starts with easy tips . . . then wades into bigger, trickier concepts.” —New York Times Book Review

“Some strong and rational suggestions for reducing your personal impact hereand when you’re eating smart, you’ll have the energy to do the movement building we need to change systems too! This book integrates the individual and the societal in a powerful way.” —Bill McKibben

“[The Climate Diet] will guide you from inaction to purpose . . . The book may be brief, but it’s solid, practical, educational, and motivating. It stays true to the goal Greenberg professes in the introduction—’to help you get from wherever you are right now to a better place in the future.’ It takes a formidable, looming crisis and breaks it down into manageable chunks that infuse the reader with a sense of hopefulness. There’s profound satisfaction in doing something, rather than nothing.” Treehugger

“[The Climate Diet] will help get America thinking as a new presidential administration moves in with climate change as a core concern. . . . This is no cookbook but rather an accessible pocket guide to the climate-focused lifestyle and reducing one’s carbon footprint. . . . The author drives home a salient point: Whatever the role of governments in curtailing carbon use, it’s up to each citizen to make their own sensible choices. . . . A quick and timely read. . . . A solid manifesto for the climate-focused life.” KirkusPaul Greenberg is the author of the James Beard Award-winning bestseller Four Fish, American Catch, and The Omega Principle, and a regular contributor to The New York Times. His writing has also appeared in The New Yorker, National Geographic, and many other publications. He has been a correspondent for PBS’s Frontline and lectured widely on ocean issues at institutions ranging from TED to Google to the U.S. Senate. He lives in New York.

Eating and Drinking

We make choices about food more often than about any other climate change driver. It therefore makes sense to begin our climate diet with our actual diet. Though it is a complicated business assigning an overall number to the carbon footprint of food, most regulators and scientists place it within the top five sources of emissions, nationally. These emissions happen directly through the operation of farm equipment, the methane burps of cows, and the transportation of product to market, and also indirectly through the replacement of powerful carbon-sequestering wild systems like forests and grasslands with CO2-leaking monocultures like corn and wheat. Even the earth beneath our feet is diminished by present methods of agriculture. The global soil stock, the world’s second largest carbon storehouse after the ocean, has lost somewhere between 50 and 70 percent of its original carbon dioxide to the atmosphere because of overtilling, overfertilization, excessive pesticide application, and other practices commonly deployed in the modern food system.

There are other important reasons to focus on fixing your food footprint. Biodiversity, water use, and exploitation of open space-key metrics in how scientists assess sustainability-are all profoundly impacted by how we grow our food. The central issue of this book, though, is greenhouse gas emissions, so I’ve organized this chapter around which food changes would have the largest impact on that metric. With apologies to the animal liberation movement (which I support), the approach here is not specifically vegan or vegetarian but rather what some call “climatarian”-an emphasis on the most realistic food changes that could be taken up by the largest number of people to lop the greatest possible chunk off American emissions. Here, then, is a baker’s dozen of changes you can make that will lighten your emissions load in the kitchen.

1
Ease up on meat and cheese. A switch to a plant-based diet shaves at least a ton of CO2 per year off your carbon footprint. But even just eating fewer pounds of animal products can be highly impactful. Beef can cost the planet more than 27 kilograms of CO2 emissions per kilogram of meat. The emissions cost of producing beef is consistently high regardless of how cattle are raised. Both ham and cheese are also emissions-intense-each of them comes in at more than 11 kilograms of CO2 per kilogram of food. Some might fret that eating fewer animal products would cause a protein deficit. Untrue. Americans actually overeat protein by about 30 percent. In spite of what fad diets might tell you, the USDA recommends only about 90 grams per day for men and 60 grams for women-less than one McDonald’s small hamburger. And unlike carbohydrates or fats, excess protein can’t be stored in the body-we literally piss it away.

2
Consider the chicken. Once you’ve reduced your overall intake of animal products, choose the kinds of protein you do eat with emissions in mind. At less than 7 kilograms of CO2 per kilogram of meat, chicken ranks as the most emissions-efficient widely produced terrestrial animal protein. True, it’s no lentil-it takes a minuscule .9 kilograms of CO2 for a kilogram of that little brown bean to come to market. But if every beef-eating American switched to chicken, the United States would cut its carbon emissions by over 200 million tons.

3
Or the fish. Wild fish can be even more carbon efficient than chicken. An average of all American wild-caught finfish comes in at 1.6 kilograms of emissions per kilogram of edible fish flesh. That’s because wild fish don’t require feed or husbandry to reach harvestable size. Nature takes care of that. The primary emissions cost of wild fish is the burden of catching them and transporting them to market. But not all wild fish are good emissions bargains. The word fish comprises thousands of species caught in dozens of different ways. Fishing methods that entail long journeys into distant waters with repeated stops to haul gear burn a lot of diesel. So, for instance, longline-caught tuna and swordfish sit near the top of the fisheries emissions list. Dragging heavy gear over the seafloor is also carbon-expensive, making flounder, cod, and other “bottom-trawled” species less desirable choices. Conversely, seafood that is caught in midwater trawls and purse seines-nets that don’t touch the bottom-tend to be carbon lightest. Alaska pollock (the fish most commonly found in your Filet-O-Fish), and small pelagic fish like mackerel, sardines, herring, squid, and anchovies, all fall into this carbon-light category. Farmed fish, meanwhile, tend to float around in an emissions space somewhere between chicken and pork.

Make oysters your appetizer instead of shrimp. All those shrimp cocktails add up: out of the 15 pounds of fish and shellfish Americans eat each year, more than 4 pounds are shrimp, making shrimp by far the most popular seafood in the United States. But shrimp, particularly farmed shrimp, are notably terrible from an emissions point of view-by some estimates as bad as beef. That’s in part because over the last few decades, shrimp farming has destroyed millions of acres of one of the world’s most powerful carbon-sequestering ecosystems: mangrove forests. Mangroves, on average, store more than twice the CO2 per acre as tropical rain forests but are often cleared to make way for coastal shrimp ponds. All this makes a shrimp cocktail an extremely carbon-intensive appetizer. Oysters, meanwhile, carry none of these costs. In fact, farmed bivalves-oysters, clams, and mussels-are extremely carbon-light. They require no feed, subsisting on a diet of wild algae and filtering and cleaning the water as they grow fat. That clever trick puts some bivalves in the same carbon cost range as many vegetables. Mussels, the grand emissions champions of the animal kingdom (and also one of the most affordable seafoo
ds out there), can cost just .6 kilograms of carbon and other greenhouse gasses per kilogram of mussel meat. Take that, lentil!

Be a picky plant eater. It’s undeniable that a good vegan diet can do more to cut a person’s greenhouse gas emissions budget than any other kind of eating pattern. But as the environmental physicist Gidon Eshel puts it, “You can be a perfectly terrible citizen of the world and be vegan, or you can be a perfectly upstanding citizen of the world while eating animals. Both are possible.” There are three main reasons for this. The first is the aforementioned point about protein. Overeating the protein component while on a vegan diet can unnecessarily add emissions pounds to what would otherwise be a green way of eating. The second problem can be food processing. Taking apart plant-based nutrients and reassembling them in such a way that makes them resemble animal products takes energy. True, the new wave of hyper-processed meat replacements (Beyond and Impossible burgers, for example) have about half the carbon footprint of chicken. But they are still about five times more emissions-intense than a simple bean patty. The third reason some plant-based diets can be problematic brings us to our next rule.

Be thoughtful with local. The food movement of the last twenty years has stressed the importance of sourcing food from local producers, and we’ve seen a tremendous proliferation of farmers’ markets as a result. Buying locally does keep family farms working and saves land from real estate development, which can in and of itself be good for emissions reductions. But local farming can be carbon intensive. In an effort to meet supermarket-style everything-always demand, some small-scale farmers have adopted practices to grow crops that don’t naturally prosper where their farms happen to be located. Take a wintertime salad. Growing greens in cold months in the Northeast requires heated greenhouses and other carbon-intensive practices. It is therefore much more carbon-efficient to get those same winter greens from California, where higher ambient temperatures and economies of scale mean that the overall carbon inputs are much lower, even when you include transport cost (about 10 percent of most food’s carbon burden). If you still want to eat Northeastern greens in the Northeast in cold months, think about something that’s regionally and seasonally appropriate, like cabbage. Be thoughtful and strategic when you drive to the farmers’ market as well. Emissions-wise, a 20-mile round trip to buy a single head of broccoli is notably wasteful.
 
7
Roots rule. In case you’re wondering which foods deliver the absolute most nutrients for the absolute least emissions, the answer according to the most recent comparative analyses is . . . carrots. Sorry not to be more exciting, but roots like carrots and parsnips carry with them a strikingly low emissions cost. The second best performer in terms of nutrients delivered per unit of carbon dioxide emitted is . . . sorry, again, not so exciting: small pelagic wild fish like anchovies. Little fish also rule.
 
8
Avoid flying food. By flying food, I mean airfreighted food. While a more hospitable, distant climate can offset the carbon cost of transporting food when the transport mode is ship or rail, airfreighting is so emissions-expensive that it blows away any other consideration. Overall, air-freighting food is fifty times more carbon costly than the least carbon intensive, transporting by ship. Flying foods are typically highly perishable products brought to us at great speed to avoid spoilage. Since fuel efficiency declines the faster you go, this is a decidedly wasteful practice. One study in the UK found that while only 1.5 percent of fruit and vegetables in that country are carried by air, they accounted for 40 percent of the total CO2 used in transport of produce for the entire nation. Flying food is almost never labeled as such in the marketplace, so a good rule of thumb is to avoid nonlocal fresh fish as well as highly perishable fruits and vegetables like berries, pineapples, asparagus, and green beans when they are out of season.
 
9
Make friends with frozen. Because frozen food can be transported slowly over longer periods of time, it is more likely to be sent via ship, which is by far the most carbon efficient way of getting food to our plates. In addition, frozen foods typically have as much nutritional value as fresh foods and, in some cases, when fresh food has been sitting on the shelf for extended periods of time, even more. Lastly, frozen foods are often cheaper.
 
10
Buy your food naked. Overall, packaging accounts for around 5 percent of food’s carbon footprint. If you must buy packaged food, reuse that packaging whenever possible to store food at home. You can also consider recyclable beeswax wrapping-a material that can be washed and reused hundreds of times-to store food. Be particularly mindful of aluminum foil. Aluminum manufacture requires a tremendous amount of electricity-around 3 percent of the global supply, resulting in 1 percent of all the world’s greenhouse gas emissions. Buy it in recycled form, clean it when you’re done, and use it again (and, if possible, again and again).
 
11
Fix your waste management. Americans throw out about 40 percent of their food. This is an egregious addition to our carbon footprint, not to mention hugely wasteful in general. But wasted food has another pernicious climate effect. Food waste in landfills, starved of oxygen, releases methane, which has a warming consequence dozens of times that of CO2. Because of food waste, the United States has larger landfill emissions than any other country on Earth, the equivalent of 37 million cars on the road each year. You should therefore think about the entire life cycle of your food before you buy it. Look at the available space in your refrigerator and freezer before going shopping. Plan weekly meals with an eye toward moving perishables from fridge to freezer as they approach their expiration dates. Once everything has been used to its fullest extent, compost what’s left. A home composting bin is easy to build or inexpensive to buy. You can even make one that works in an apartment (see the Resources section at the end of this book for a guide). If you don’t have access to composting space, see if your town or city has a composting program. If it doesn’t, encourage your elected officials to start one.
 
12
Cook smarter. Cooking accounts for 4.5 percent of household energy use-not a lot, but worth addressing as it’s a fairly easy fix. Putting lids on your pots when you boil water, for example, cuts cooking time (and energy use) in half. Soaking not just beans but also pasta in advance of cooking is similarly effective in reducing energy consumption. More ambitiously, you could consider replacing your gas stovetop with an electric one. Gas poses many climate problems-which I’ll discuss in further detail in the “Staying Home” chapter-but the most glaring one is that when you cook on a gas stove, only about 40 percent of the energy from the flame gets to your food. Since gas ranges are responsible for the majority of the toxic nitrogen oxides that end up trapped in your home, switching to electric also has significant health benefits. Induction electric stovetops, which conduct 80 to 90 percent of cooking energy into your food, can cost under $150 for a simple plug-in, two-burner model.
 
13
Drink from the tap. Tap water is by far the cheapest drink we can consume in terms of both emissions and money. Nevertheless, the average American drinks about 42 gallons of bottled water every year-spending about $18 billion annually or something like $50 per person annually. A 2007 study found that making the billions of plastic bottles manufactured every year to hold all of that water used the equivalent of around 17 million barrels of oil-enough energy to fuel more than a million American cars and light trucks for a year. Yes, contamination of the American public water system is a serious problem, and we need to fight for clean, safe drinking water for all. But 90 percent of Americans have access to clean water 365 days a year. For some of the remaining 10 percent, an inexpensive water filter can address the problem (see the Resources section at the end of this book for a guide).
