I think enhanced rock weathering (#ERW) has the potential to scale as a CO₂ removal (#CDR) technique, but there's no f**king way that they can be sure that they've removed 50 tonnes of CO₂ from the atmosphere right now. We don't have the #MRV techniques to do this today.

Enhanced rock weathering (#ERW) seems like a promising way to remove CO₂ from the atmosphere. However, this paper says that to remove 1 billion tonne of CO₂ per year requires land area larger than the entire United States.

#CDR

Silicates were applied to Hubbard Brook Forest in New Hampshire. Mining, grinding, transport, and application of the mineral released 18 to 87x more CO₂ than was removed by enhanced rock weathering (#ERW) over 15 years.

We should absolutely research and develop ERW as #CDR, but it will be a long time (if ever) before these industrial processes are decarbonized and we cannot count on ERW as a climate solution until it removes more CO₂ than it releases.
