Reducing coffee carbon emissions through improved varieties

A critical pathway for slowing emissions growth


The objective of this white paper is to describe the potential to decrease the carbon footprint of coffee farming through increased coffee yields achieved using improved varieties.

Key takeaways

  • The development and widespread adoption of higher-performing coffee varieties has the potential to substantially reduce greenhouse gas emissions from coffee agriculture.
  • Using higher yielding varieties could reduce the carbon footprint of arabica coffee farming by 32%. This impact is modeled using an improved carbon accounting method for coffee, and real variety performance data coming from the world’s largest arabica variety performance trial, with 29 sites in 18 countries.
  • The creation of improved, higher-yielding varieties is a critical pathway for slowing GHG emissions growth from coffee agriculture as global demand continues to rise.
  • This paper demonstrates the potential carbon emissions savings that could be obtained from higher yielding varieties without changing other inputs (such as fertilizers).
