Project period: 08/2021 – 01/2024

Enhanced coffee farmers’ knowledge on GHG emissions and their capacity to implement emission reduction measures and good agricultural practices:

  • Development of dedicated training curriculum adapted to local context.
  • 20 field officers and 40 lead farmers trained as multipliers to disseminate knowledge among the farmers.
  • 44 demonstration plots established as key learning centres to showcase results of adopting sustainable practices.
  • More than 8000 farmers have been trained on topics such as climate change and coffee production, good agricultural and climate smart practices, record keeping, water management on the farm, pruning of coffee plants, plant nutrition and soil health, and shade management and agroforestry practices.
  • Nursery establishment with more than 320,000 shade trees of the species Macadamia, Mango, Avocado and Mihumula distributed to farmers for better shade management and possibilities for income diversification.

GHG emissions calculation from production and processing of Robusta coffee:

  • Development of a transparent and updatable GHG calculator and digital data collection system.
  • Data collection from more than 100 coffee farms, 13 Agricultural Marketing Cooperative Societies (AMCOS) and the dry mill to establish a base and endline on GHG emissions.
  • 22% reduction of GHG emissions in 2024 compared to the baseline from 2021.
  • First, 4C Carbon Footprint Add-on Certificate issued to KDCU supporting market uptake of their climate-friendly coffee.

The project region, Kagera, in the northwest of Tanzania, already bears evidence of these developments. The region lost 34.5 kHa of tree cover between 2001 and 2019, which is equivalent to almost 6 Mt of CO2 emissions. Research projects have identified specific GHG emissions hotspots in the Tanzanian coffee supply chain that need to be addressed with efficient reduction measures.

Project Measures

Measuring initial GHG emissions is the first crucial step to understand and quantify the negative environmental impact of coffee production in the project region. To allow for an adequate baseline measurement of GHG emissions, a joint workshop with the project partners was held to map JDE Peet’s coffee supply chain in the region and define the system boundaries.

Based on the mapping results, Meo Carbon Solutions conducted an in-depth analysis to develop a customized data collection template with the support of KDCU, the local coffee cooperative and Touton, the international supply chain manager.

Data was then collected from 126 coffee farmers and 13 Agricultural Marketing Cooperative Societies (AMCOS) as well as the dry mill of the local implementing partner KDCU. For the assurance of a representative sample of the farms, the whole group was clustered along the annual yield and area of the farm and sampled farms were selected from the four resulting clusters.

More Information

The baseline data collection was complemented by the work of Global Risk Assessment Services (GRAS) who conducted a land use change analysis to determine the potential deforestation risk areas within the project region. In addition, soil samples were collected from the 126 sampled coffee farms to determine the baseline soil organic carbon content.

Following the data collection process, Meo Carbon Solutions developed a customized GHG emission calculator based on the methodology of the 4C Carbon Footprint Add-on, considering recognized standards and initiatives such as ISO 14067:2018, GHG Protocol Product Standard, PAS 2050:2011 and IPCC guidelines. Further the Carbon Footprint Add-on is aligned with the guide from the Science Based Target Initiative (SBTi) and the Paris Agreement. With the baseline data and the developed GHG calculator, the total amount of GHG emissions for the coffee production from cultivation to the dry mill were calculated in kg Co2 equivalent per ton of green coffee.

The data collection process was repeated twice during the project, once in 2023 and again in 2024 for the endline. Each cycle showed significant improvements in data accuracy due to increased enumerator experience and the refined and targeted training programs.

To further develop the GHG reduction strategy, identifying the sources of emissions on each of the different levels in the supply chain was key. At the farm level the primary emission drivers were identified as the use of fertilizers and transportation. For the AMCOS level also transportation played a crucial role alongside with plastic consumption. This is also true for the dry mill level, where also energy consumption contributes to the GHG emissions.

The results from the baseline data collection and GHG emission calculation supported the identification of potential emission reduction strategies as well as in-setting opportunities. 4C, Meo Carbon Solutions, JDE Peet’s, Touton and KDCU worked very closely together to identify suitable measures and to provide technical and financial support to farmers to implement the identified measures. The focus of the reduction measures was being put on improving cultivation through good agricultural practices with the aim of improving soil quality and increasing yields.

To strengthen the capacity building, a training curriculum tailored to the context of the project region has been developed to support farmers in the implementation of climate-smart agricultural practices.

The training material was tested in the field and feedback from trainers and target groups has been integrated into the final training material. For the purpose of the trainings and dissemination of knowledge to farmers, demonstration plots have been established where recommended measures are being applied and shown with the respective results to farmer groups. Training sessions with farmers started in the beginning of 2023 and lasted until the end of the project in November 2024. To allow for direct practical implementation, the training sessions were aligned with the coffee calendar, teaching each topic during the time of the year when it is relevant to be implemented by the farmers.

To support additional emission reduction and carbon removals within the supply chain, as part of the project, a nursery for shade tree seedlings was set up. In this nursery, seedlings for macadamia, mango, avocado and other local shade trees were grown and handed out to the farmers participating in the project. The seedlings will grow into shade trees and support farmers in creating an optimal climate on their coffee farm, besides storing carbon and providing additional income opportunities to the farmer’s household through the sale of the fruits.

As the emissions identified in the analysed supply chain are comparably low, the possibility for carbon offsetting options to enable reasonable compensation for unavoidable GHG emissions was explored, though due to project constraints not further pursued.

4C has developed a Carbon Footprint Add-On to be used on top of our core standard. The farmer groups participating in this project in the Kagera region were among the first 4C users implementing this new feature. The 4C Unit obtained their 4C Climate Friendly certification in September 2022. A clear system boundary was set to facilitate the calculation of GHG emissions. The baseline GHG calculation, the annual updates for the maintenance of the certificate, and the monitoring of emissions in the framework of the project significantly contributed to the development of the 4C Carbon Footprint Add-On by providing learnings from the ground, related to sampling procedures, data quality and recording of inputs.

Awareness-raising campaigns are being conducted to distinguish coffee with reduced GHG footprint and the 4C Climate Friendly label is increasing its market uptake in Europe. The long-term viability and continuous market uptake of Climate Friendly green coffee from the project region will be ensured through credible high-level sustainability certification, marketing and communication campaigns and the development of local and international partnerships.

The project results have been disseminated within the project region and beyond through multistakeholder workshops with relevant actors from Tanzania and neighbouring countries. After testing the developed training curriculum on climate-smart coffee production in the context of the project, it was handed over to the local implementing partner KDCU, cooperating with more than 130 AMCOS in the region, together gathering almost 65,000 farmers, to provide for continuous knowledge sharing. Beyond Tanzania, project results were shared on several events online as well as in-person with stakeholders interested in the 4C Carbon Footprint Add-on and GHG emission calculations and reduction measures.
