Lucas Joppa, Amy Luers, Elizabeth Willmott, S. Julio Friedmann, Steven P. Hamburg, Rafael Broze IN: Nature 597, 629-632 (2021) doi: https://doi.org/10.1038/d41586-021-02606-3
The authors summarized the lessons learnt from Microsoft’s carbon-removal efforts, along with those from another early corporate procurement — the $9-million purchases of carbon removal in 2020 and 2021 by the US–Irish financial-infrastructure company Stripe. Although these are just two companies’ efforts, they are the first significant open solicitations focused exclusively on carbon removal. They write as a team composed of Microsoft staff working on the company’s carbon-negative programme and research scientists who analyse carbon reduction and removal strategies.
