A change of pace now, with Pete Smith from @aberdeenuni speaking about soil carbon sequestration (SCS) and biochar:
What’s good with these two NETs, says Smith, is that you can continue to use the land – e.g. to grow crops – and actually make it more productive.

SCS and biochar are relatively low cost with low demand for land and water, says Smith. Makes them “no regret” options (relatively...)

“So, if SCS and biochar are so fantastic, why aren’t we doing them?” asks Smith
They have some caveats, he says: saturation (after 20-50 years), permanence (gains in C easily lost), leakage/displacement (are we storing C or just moving it about?) #negco2
