About this episode

Marcelo Medeiros discusses re.green's approach to high-quality nature-based carbon removal and its impact on forest restoration in Brazil.

Marcelo Medeiros, co-founder and CEO of re.green, joins Climate Rising to discuss how his company is restoring millions of hectares of degraded land in Brazil’s Atlantic Forest and Amazon biomes by producing high-quality nature-based carbon removal credits. Marcelo explains how re.green combines data science, forest restoration, and long-term land ownership to deliver durable carbon sequestration—and why they chose a for-profit model to scale impact. He discusses price transparency, quality verification, and how re.green is preparing for a future where compliance carbon markets may accept removal-based offsets from nature-based solutions. Marcelo also shares how winning the Earthshot Prize brought global visibility, how AI is improving ecosystem planning, and how the company works with clients like Microsoft and Telefónica under long-term offtake agreements.
