Joppa, Lucas; Luers, Amy; Willmott, Elizabeth; Friedmann, S. Julio; Hamburg, Steven P.; Broze, Rafael (2021): Microsoft's million-tonne CO2-removal purchase - lessons for net zero. In Nature 597 (7878), pp. 629–632. DOI: 10.1038/d41586-021-02606-3.
"Strengthen markets, measures and definitions for removing carbon dioxide from the atmosphere to fight climate change. In January this year, Microsoft made a major announcement: it had paid for the removal of 1.3 million tonnes of carbon dioxide from the atmosphere. Among its purchases were projects to expand forests in Peru, Nicaragua and the United States, as well as initiatives to regenerate soil across US farms. [...] Here we summarize 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. We 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."
