Discover how Kenya’s Baragwi Coffee Cooperative and KTDA’s Momul Tea Factory revolutionized sustainable sourcing, slashing emissions by 28%, boosting farmer incomes by 20%, and unlocking premium markets through Rainforest Alliance certification—actionable insights for greening your supply chain in East Africa and beyond.
By Ethical Business Analysis Desk
Sustainable sourcing is no longer a choice—it’s a necessity for businesses facing environmental pressures and consumer demand for ethical products. In East Africa, where agriculture powers economies, greening supply chains means balancing profitability with ecological and social responsibility. This blog post examines two real-world examples: Baragwi Farmers Cooperative Society in Kenya’s coffee sector and the Kenya Tea Development Agency’s (KTDA) Momul Factory in the tea industry. Their journeys offer practical insights for businesses aiming to source responsibly.
Baragwi Farmers Cooperative: Coffee in Kirinyaga
Nestled at the base of Mount Kenya, Baragwi Farmers Cooperative Society unites 2,500 smallholder farmers growing premium Arabica coffee on volcanic soils. By 2010, Baragwi faced declining yields due to aging coffee trees, climate-driven pests like coffee berry disease, and buyer demands for sustainable practices. Their traditional supply chain relied on intermediaries, inefficient wet milling, and diesel-based transport, which eroded profits and increased emissions.
“We knew we had to change to stay competitive,” says Cyrus Chumba, a Baragwi manager. Partnering with the Rainforest Alliance in 2010, Baragwi transformed its supply chain, focusing on regenerative agriculture, eco-friendly processing, and social accountability. By 2024, coffee production tripled from 5 million to 15 million kilograms of cherries, emissions dropped, and farmer livelihoods improved.
KTDA’s Momul Factory: Tea in Kericho
In the misty highlands of Kericho, KTDA’s Momul Factory represents 12,500 smallholder tea farmers within KTDA’s network of over 600,000 growers across 54 factory companies. In 2009, a public-private partnership with Unilever and Rainforest Alliance piloted group certification at Momul, addressing challenges like deforestation, water-intensive processing, and unsafe agrochemical use. “Certification gave us a way to prove our tea was sustainable,” says Jane Kipkorir, a lead farmer at Momul. The initiative focused on environmental stewardship, fair labor, and economic viability, achieving the largest group certification of its time.

Operational Changes That Worked
1. Empowering Farmers Through Training
Baragwi: The cooperative trained farmers in regenerative agriculture, including intercropping with shade trees and organic composting, reducing chemical fertilizer use by 50%. By 2024, 85% of farmers adopted disease-resistant Ruiru 11 coffee varieties, boosting yields by 20%. These changes improved bean quality, fetching premium prices.
Momul: KTDA’s farmer-field schools, led by trained “Lead Farmers,” reached 12,500 growers, teaching soil conservation, safe agrochemical use, and wildlife protection. Over 575,000 KTDA farmers benefited from similar programs, enhancing biodiversity and safety practices.
2. Greening Processing and Logistics
Baragwi: Water-intensive wet mills were upgraded with water-efficient pulping equipment, cutting usage by 40%. Solar-powered drying beds reduced energy costs and emissions by 25%. Hybrid vehicles and route optimization software slashed fuel use by 30%, while partnerships with local startups introduced electric motorbikes for last-mile transport.
Momul: KTDA invested in water-saving processing technologies, reducing consumption by 35%. Solar energy powered factory operations, and hybrid trucks cut logistics emissions by 20%. Group certification streamlined audits, lowering costs for smallholders.
3. Enhancing Transparency and Certification
Baragwi: A digital tracking system logged farming and processing data for each coffee batch, accessible via QR codes. Rainforest Alliance certification secured contracts with German and Swedish buyers, increasing export revenue by 12% in 2024. Policies against child labor strengthened ethical practices.
Momul: The Rainforest Alliance’s Sustainable Agriculture Network (SAN) standard ensured compliance with social, labor, and ecological criteria. Certification enabled traceability, attracting premium buyers like Unilever, who committed to sourcing only certified Kenyan tea by 2015. Digital records improved transparency, boosting market trust.
4. Financing Sustainability
Baragwi: The cooperative facilitated access to low-interest loans through local microfinance institutions, enabling farmers to invest in organic inputs and protective gear.
Momul: KTDA’s Greenland Fedha microfinance vehicle provided low-interest loans for sustainable inputs and PPE, empowering farmers to meet certification standards without financial strain.
Measurable Outcomes
- Environmental Impact:
- Baragwi: Regenerative practices and solar drying reduced carbon emissions by 28% (1,000 metric tons of CO2 annually). Water-efficient processing conserved 500,000 liters yearly.
- Momul: Water-saving technologies and solar energy cut emissions by 22% and conserved 600,000 liters of water annually across KTDA factories.
- Economic Gains:
- Baragwi: Farmer incomes rose by 20% due to higher yields and premium prices. Direct trade cut intermediary costs.
- Momul: Certified farmers earned 15% more through premium markets, with group certification reducing per-farmer costs by 30%.
- Market Access:
- Baragwi: Rainforest Alliance certification increased export volumes by 10%, opening European markets.
- Momul: Certification secured Unilever contracts, boosting export revenue by 8% by 2015.
- Social Benefits:
- Baragwi: Women farmers now hold 35% of leadership roles, and anti-child labor policies strengthened community trust.
- Momul: Improved working conditions and PPE access enhanced farmer well-being, with women comprising 40% of lead farmers.
Lessons for Businesses
The successes of Baragwi and Momul offer actionable insights for greening supply chains:
- Train Local Leaders: Both leveraged trusted “lead farmers” to scale knowledge. Businesses can train supplier champions to drive sustainable practices.
- Use Affordable Green Tech: Solar drying (Baragwi) and water-efficient processing (Momul) aligned with Kenya’s renewable energy grid. Identify cost-effective technologies in your region.
- Leverage Group Certification: Momul’s model reduced costs by pooling resources. Aggregate suppliers to share certification expenses.
- Finance Sustainability: Microloans (Greenland Fedha for Momul, local institutions for Baragwi) enabled investment in green inputs. Partner with microfinance to support suppliers.
- Balance Certification Costs: While Rainforest Alliance opened markets, its $3,000 annual fees per factory sparked debate in 2025, leading Kenya to explore local certifications. Choose certifications that justify costs with market access.

The East African Context
East Africa’s supply chains face infrastructure gaps, climate variability, and smallholder reliance, but these spur innovation. Kenya’s 90% renewable energy grid supported Baragwi’s solar drying and Momul’s factory upgrades. Government policies, like the Coffee Bill 2023 and tea sector reforms, incentivized fair pricing and sustainability. Community engagement was key—Baragwi’s workshops and Momul’s field schools ensured farmer buy-in by addressing income concerns. However, the 2025 suspension of Rainforest Alliance audits for tea factories, due to high costs, highlights the need for affordable, locally tailored certification models. Businesses must align with regional resources and engage stakeholders early.
Call to Action
Baragwi and Momul prove sustainable sourcing is viable, even for smallholder networks. Start by auditing one supply chain segment—transport or supplier practices—and test a change, like water-saving tech or training programs. Explore resources like Rainforest Alliance guides or Kenya’s Coffee and Tea Platforms for strategies. Every step strengthens your business and the planet.
