Glyphosate Use Plays A Key Role In Reducing Global Carbon Dioxide Emissions From Agriculture
6 January 2026. Glyphosate, the world’s most used herbicide annually provides a positive contribution to reducing global carbon dioxide equivalent (CO2e) emissions arising from agricultural production of between -32.17 billion kg and -45.18 billion kg, equal to taking between 21.3 and 29.9 million cars off the road each year. This is a primary conclusion of a new peer reviewed paper in the journal GM Crops and Food by agricultural economist Graham Brookes. This positive contribution stems from glyphosate’s instrumental role in facilitating a shift in farming production practices that are tillage-based into conservation tillage systems based on reduced and no tillage.
