This plan might be transparently self-serving, but Shell’s outsize ambitions for carbon removal are far from anomalous. A growing number of companies are setting up programs to create or trade carbon offsets, using tree planting, soil management, and other means to purportedly balance out emissions elsewhere. Meanwhile, numerous corporations and nations are announcing “net zero” emissions plans that rely upon these programs, and rapidly proliferating carbon-removal startups are highlighting what some consider overly rosy projections in their investor pitch decks.

The noise, news and hype are feeding a perception that carbon removal will be cheap, simple, scalable, and reliable—none of which we can count on.
