Abstract
Many modeling studies depend on direct air capture (DAC) in their 1.5°C stabilization scenarios. These studies rely on assumptions that are overly optimistic regarding the cost and scaling-up of DAC systems. This can lead to highly misleading results that can ultimately impact the ability to reach climate stabilization goals.
All too often trees are a way to cheat, greenwashing when you don’t actually care about making change. It’s not that planting trees aren’t effective and cost efficient, but that it’s easy to play fast and loose with whether you actually made a difference
