Episode notes
Founding Genesis: Finance Meets Restoration Science
- Marcelo Medeiros formed re.green by pairing his finance background with Bernardo Strasberg's restoration science and several PhDs.
- The founding team also recruited a large-scale forestry COO to scale planting operations across Brazil.
Large-Scale Restoration Is Feasible Without Food Risk
- Restoring 15% of converted land is feasible without threatening food security, says the Nature-based study re.green used.
- In Brazil, 160M ha of pasture could be halved through productivity gains, freeing ~80M ha for restoration or agriculture.
Secure Land And Legal Protections For Integrity
- To ensure integrity, buy degraded land, actively restore it, and create legal protections to guarantee permanence.
- Design restoration to meet the highest additionality and permanence standards and then offer that product to buyers.
