A common complaint I hear levied against CDR is that it is too expensive compared to alternative climate change prevention strategies. While this complaint is entirely fair on the whole, there are likely a handful of “low hanging fruit” opportunities on the CDR supply curve that make sense for us to pursue today.
Take, for example, a recent article in The Daily Climate explaining how replacing grass with shrubs can help highways remove carbon. This simple, inexpensive approach isn’t what first comes to mind when we think of CDR. And it won’t have the long term potential of more complex CDR systems like bioenergy facilities with carbon capture and sequestration or even direct air capture units. But that is no reason to delay implementing these incremental CDR solutions until market conditions to support larger-scale CDR systems emerge.

Most importantly, this roadside CDR article shows us the value of searching for CDR opportunities hiding in plain sight. Would it be possible to turn residential lawn mowing businesses into small-scale CDR businesses? With creative thinking in the lines of the roadside afforestation project, its very well possible. And with enough people thinking about how they can contribute to a carbon sequestering (instead of carbon emitting) economy, we might be able to generate significant amounts of unexpected CDR, and even find breakthrough solutions in places where we never thought to look.
