A Card's Real Carbon Cost Isn't About Paper or Pixels — It's About Being Remembered

You might already know that digital cards carry a smaller carbon footprint than paper ones. A typical digital send costs around 50 grams of CO2 equivalent, compared to 140 grams or more for a paper card — the math is fairly settled.

But here's what matters more: whether anyone actually opens the thing.

A card that gets skimmed once and forgotten has wasted its entire footprint — whether it was printed or transmitted. A generic greeting sent to dozens of people "just because" spreads that waste across a dozen unopened drawers. Meanwhile, a single, personalized card that someone opens, feels, and keeps — even if it took slightly more energy to make — has spent its footprint on something that lands.

Sustainability in messaging isn't only a materials question. It's also a design question — whether the thing you're sending is worth someone's attention in the first place. A card built around a specific memory, a real photograph, or a genuinely personal touch is more likely to be opened, felt, and remembered than a generic one.

That's the actual lever.
