Unilever has been an active proponent of schemes to broaden the supply-base and support local livelihoods, particularly in its tea and palm-oil estates.

Lipton/Unilever Tea has a partnership with Rainforest Alliance on sustainability certification. Another partnership with Tanzania Forest Conservation Group, Ministry of Natural Resources, World Agroforestry Centre and the World Conservation Union also promotes Allanblackia seed production for fat/oil, as a substitute for palm oil in spreads, soap and as an alternative source of farmer income.

Farmers, transporters and crushers benefit, and the value of Allanblackia trees encourages farmers to reverse deforestation.
