Reducing On-Field Greenhouse Gas Emissions: Reporting Methodology
Reviewed by External Experts
Bayer aims to demonstrate a method for measuring on-field GHG emissions in a reasonable approach and that the baselining and performance tracking methodology is adequate.
The main objective of this report is to document how Bayer quantifies greenhouse gas (GHG) emissions and soil carbon sequestration. More specifically, this report documents how Bayer compiles inventory data to quantify GHG emissions and conducts a sustainable intensification impact assessment to achieve Bayer’s target to enable its farming customers to reduce their on-field greenhouse gas emissions per mass unit of crop produced by 30% by 2030 compared to the overall base year emission intensity1. This applies to the highest greenhouse gas emitting crop systems in the regions Bayer serves with its products.2
This page is home to the methodology report which has gone through 3 cycles of rigorous expert panel reviews. Here, the methodology report can be found, containing information on the strategic intent behind Bayer’s GHG target and a description of the overall methodology.
[1] Our reduction target refers to an overall base year greenhouse gas intensity that includes the weighted emission intensities of 17 crop-country combinations (CCCs). In 2024, the CCC Australia-Cotton was removed from the scope due to the unavailability of data. Base years are defined individually for each CCC, using data from either harvest year 2021 or 2022 depending on the availability of data. Base years were adjusted in 2024 due to additional data requirements based on an updated GHG calculator methodology and lack of data availability from prior years.
[2] The CCCs Italy-Corn and Spain-Corn were not selected based on these factors but were additionally included because data were already available.
