Data Collection for GHG Emissions Using 4C Carbon Footprint Add-On Methodology
The coffee industry faces significant challenges due to climate change, so measuring the carbon footprint of green coffee is essential for identifying emission hotspots and developing effective reduction strategies.

Project Background
4C successfully implemented a project funded by the Center of Global Commons at the University of Tokyo, entitled ‘Data collection for GHG emissions using 4C Carbon Footprint Add-On‘.
Project Overview
Project title: Data collection for GHG emissions using 4C Carbon Footprint Add-On.
The project collected data in three key origins: Brazil, Colombia and Vietnam.


Project Management: 4C Services GmbH.
Project funded by: Center for Global Commons, University of Tokyo.
Project collaboration: This project represents strong collaboration between 4C and a key research partner at the University of Tokyo, strengthening the 4C Carbon Footprint methodology and working with local partners to map carbon emissions in the coffee supply chain.
Local Implementing partners: Simexco Daklak Ltd. Vietnam, Cocatrel, Sucden Colombia.

Technical Partner: Meo Carbon Solutions.
Project period: September 2024 to March 2025
Key Lessons
Data quality and sampling are key to robust greenhouse gas calculations.
Dedicated training for enumerators and local implementing partners improved the quality of the data.
Local implementing partners who participated in the 4C Carbon Footprint Add-On training course gained a better understanding of the 4C Add-On methodology...
Deliverables
Collected data using tailored data request template for 3 key origins – Brazil, Colombia, and Vietnam.
Improved capacity building of local implementing partners on data collection, sampling, and data quality.
Developed 3 customized greenhouse gas (GHG) calculators for Brazil, Colombia, and Vietnam using 4C Carbon Footprint Add-On
Estimation of soil organic carbon (SOC) using the laboratory analysis of soil samples.
Estimation of Biomass Organic Carbon (BOC) for the agroforestry trees planted on the farm using allometric emissions.
