The decarbonization of agricultural chains has become central in discussions about climate goals, especially in the face of the challenge of measuring and reducing Scope 3 emissions that, for many companies, begin in the field. This was the focus of the fourth edition of the Carbon Science Talks, held by Bayer, at Amcham Brasil in São Paulo, which brought together companies, researchers, and farmers to discuss solutions capable of measuring, proving, and accelerating the adoption of sustainable practices on a large scale.
