Coffee Calculations

Coffee Calculations

In our morning haze, we've been debating whether to give up coffee again. Ever since that pesky little sustainability calculator that we blogged yesterday, we've been looking for ways to conserve—or rationalize.

We're not alone. Jesse@humanrecipe commented, "I think my 8 cups of coffee a week did me in." So we went back for some quasi-scientific analysis.

Let's say we drink a lot of coffee: a 20 ounce venti something-something in the morning, a "regular"-size (16 ounce) cup in the afternoon for a pick-me-up, and, just for the sake of argument, a teensy little decaf espresso after dinner in the evening. That adds up to the equivalent of at least 6 eight ounce cups of coffee every day, and that adds up to 42 servings per week.

Changing the counter from 0 cups to 42 cups adds 0.2 planets to the total. That's not a huge difference, but, again, it's scale that counts: if just five of us gave up coffee, we'd save the entire earth!

Joking aside, we're wondering if you've given up coffee. We did once, for about 18 months, and it was a time of calm and clarity, with mornings blessedly free of caffeine cravings. We're thinking it might be time to do it again.

...but excuse us for a moment while we get just one more cup.
