Learning curves and cost deflation are widely assumed in new energies but overlooked for nature-based CO2 removals. This 15-page note finds the CO2 uptake of reforestation projects could double again from here. Support for NBS has already stepped up sharply in 2021. Beneficiaries include the supply chain and leading projects.
Nature based carbon removals are re-capped on page 2, covering their important, their costs and how they are re-shaping the energy transition.
But policy support is growing faster than expected, as outlined on pages 3-5. Now that nature-based CO2 removals are on the map, they are in competition with other new energies. Hence which technologies will ‘improve fastest’?
The historical precedent from agriculture is that yields have improved 4-7x over 50-100 years, due to learning curve effects. So will forestry practices be similar? (pages 6-7).
Thirty variables can be optimized when re-foresting a degraded eco-system. We run through the most important examples on pages 8-13.
But is optimizing nature ‘natural’? This is a philosophical question. Our own perspectives and conclusions are offered on page 14-15.
