Getting the biggest nutritional bang for our climate buck (especially for that $4 Latte)

There are recent headlines about Starbuck's 2020 initiative to reduce their carbon footprint and part of that strategy is offering plant based alternative drinks vs the traditional dairy based ingredients.

No matter what you order at starbucks, the impact is probably minimal compared to the impact of simply how you get there.

Given that consuming #beef in the U.S. accounts for less than .5% of global greenhouse gas emissions, it's no doubt eating a salad in a restaurant or a veggie sub is less climate friendly than a steak at home. https://t.co/dVKTRx83k1

Maybe you can get past that argument if you are combining trips.

But combining trips makes for a good analogy when it comes to the carbon footprint of our food.

How do we know we are getting the most nutritional bang for our climate buck. In a 2010 Food and Nutrition Research article, authors introduce what they are calling a Nutrient Density to Climate Impact (NDCI) index that takes this into account. According to their work:

"the NDCI index was 0 for carbonated water, soft drink, and beer and below 0.1 for red wine and oat drink. The NDCI index was similar for orange juice (0.28) and soy drink (0.25). Due to a very high-nutrient density, the NDCI index for milk was substantially higher (0.54) than for the other beverages. Future discussion on how changes in food consumption patterns might help avert climate change need to take both GHG emission and nutrient density of foods and beverages into account."

Just as combining trips and carpooling might be effective ways to reduce your carbon footprint getting the most out of every mile driven and gallon of gas used, we should be trying to get the most out of every bite we take and ounce we drink. Starbucks could help us do this by supporting our dairy farmers and emphasizing the very high NDCI for milk! After all, it does a body good.
