Today is World Zero Emissions Day. Every 21st of September since 2008, we give our planet a break from fossil fuels and what they release into the air. That is, greenhouse gasses, polluting substances, microparticles and other happy things that we’d rather leave into the ground rather than release into the atmosphere we – and all other living things in the known universe – breathe.

Although we have known about the greenhouse effect since the mid-XIXth century, it took a long time to get an actual understanding of where these emissions came from precisely.

Humans have gotten good at measuring who emits what, how and why. It is instrumental to humanity to understand which of our activities burn up the most fuel so we can act accordingly and smartly.

To make it a bit less dry, we made these excel sheets a bit more agreeable to the eye and to the mind.
