Coffee’s Invisible Carbon Footprint

Climate

By Sarah McColl

Think of the environmental impacts of coffee and your mind likely goes to mountains of coffee cherries polluting waterways, piles of leftover grounds, nonrecyclable coffee pods or the paper waste from gazillions of grande to-go cups. Initially, you're probably not considering milk at all.

Milk represents 60 to 70 percent of the carbon footprint of a cup of coffee with a few tablespoons of milk; for a latte, it's more like 80 or 90 percent. Per cup, black coffee produces 21 grams of CO2; each latte, 340 grams.

“You and me both," Robert Myers, cofounder of San Francisco's Paramo Coffee, said, whose focus, understandably, had been on the coffee aspects of his coffee business, from farming practices to roasting. But when your business partner is also involved in The Perennial, a restaurant out to fight climate change—as Paramo's Wes Wang is—you start getting articles sent to you. An article about the carbon footprint of heating water for coffee, articles about the emissions related to the aforementioned milk. “I was like, 'Oh great, now milk is a huge part of the problem,'" Myers said.

The milk math Paramo Coffee did was incriminating. Milk represents 60 to 70 percent of the carbon footprint of a cup of coffee with a few tablespoons of milk; for a latte, it's more like 80 or 90 percent. Per cup, black coffee produces 21 grams of CO2; each latte, 340 grams. “When you figure a coffee shop makes 300, 500, 700 drinks a day, this becomes significant," Myers told SFGate.

But rather than imagine a joyless life without lattes, Myers started to learn more about potential offset solutions, such as carbon farming. In this practice, land is covered in a layer of compost, then planted with perennial grasses. Compost seeds the soil with good microorganisms and carbon is captured and stored in the soil via the deep root system of perennial grasses.

“It's not just give up coffee, give up milk," he said. “Suddenly it seemed like, oh, there might be something we can do."

That something has taken the form of a new Paramo location next to The Perennial with a more energy-efficient roaster and a partnership with Marin County's Straus Family Creamery—which, among the nine dairy farms it works with, sources from one that has converted some of its grazing land to carbon farming. Since Paramo can't source milk solely from cows grazing on land that has been converted to carbon farming, it donates 5 cents from every drink to Marin Carbon Project to offset the cost of converting additional dairy rangeland.

Scientists think inexpensive, low-technology practices like carbon farming can turn back the carbon clock. The world's cultivated soils have lost between 50 and 70 percent of their original carbon stock, but carbon farming can reduce atmospheric CO2 while also increasing the health and productivity of the soil. Research from the University of California at Berkeley found that if compost were applied to 5 percent of the state's grazing land, it could store a year's worth of emissions from conventional farms and forestry operations. Boost that number to 25 percent of grazing land and the soil would absorb 75 percent of California's total annual emissions.

“That's a huge impact," Myers said. “It feels like we could really change things in a big way and within the context of something I'm already doing, which is selling coffee with milk. It's not an additional thing I have to do—it's just being more mindful and being a steward of my piece of it."

“If we can say, 'I can sell this milk, there's a lot of demand for it' and if we just keep asking for it, I'm hoping that will get more farmers to say, 'Well, maybe we should try this,'" he added

In a story about The Perennial, Chris Ying, cofounder of both the restaurant and ZeroFoodprint, told TakePart, “Eating, it turns out, is the most significant interaction most of us have with the environment." But the coffeeshop relationship is a unique one. For many coffee drinkers, the morning ministrations of our local barista may be meaningful enough to encourage us to consider the environmental impacts of the ritual.

“You enter into a type of intimacy that's very genuine," Myers said. “I think that's an opportunity to get into people's heart space—gradually, in small ways. But that's where I think the battle of environmental issues wins, when you can get into that space."

Scotland produced enough power from wind turbines in the first half of 2019, that it could power Scotland twice over. Put another way, it's enough energy to power all of Scotland and most of Northern England, according to the BBC — an impressive step for the United Kingdom, which pledged to be carbon neutral in 30 years.

It's been a particularly terrible summer for bees. Recently, the U.S. Environmental Protection Agency (EPA) announced it is allowing the bee-killing pesticide sulfoxaflor back on the market. And just a few weeks prior, the USDA announced it is suspending data collection for its annual honeybee survey, which tracks honeybee populations across the U.S., providing critical information to farmers and scientists.
