Johnny got in touch to ask:

"Does burying paper in a landfill sequester carbon?"

Can anyone dig up an answer?

Probably not for very long.

In a landfill, paper is mixed with water and other chemicals (some from food waste).
This encourages the growth of a bacterial ecosystem which will break down many of these chemicals, producing carbon dioxide, which will escape into the atmosphere from the landfill.

Even worse, it may escape as methane, which is a more powerful greenhouse gas than carbon dioxide.
