• The Institute for Environmental Innovation (I4EI) supports more than 13,300 Small Groups to take locally-determined action for environmental renewal, food security, community leadership, health and climate change.

  • We provide technology, organization and resources to help 90,000+ subsistence farmers in India, Kenya, Tanzania and Uganda plant 19,000,000+ trees and reverse the effects of deforestation, drought and famine.

    We work with the TIST Program to accomplish our mission.

    TIST Program participants include women and young people, many without land ownership, who have raised more than 19 million trees through their efforts and ingenuity.

    The men and women in TIST Small Groups are starting nurseries, planting trees, raising bees, making compost and adopting improved agriculture practices for a larger harvest.

    TIST farmers learn about HIV/AIDS, malaria, nutrition and construction of fuel-efficient cook stoves that protect women and children from breathing harmful smoke.

  • We support the sustainable development, biodiversity, leadership and health initiatives of TIST (The International Small Group and Tree Planting Program).


    I4EI is a 501(c)3 Public Charity and all U.S. donations are tax-deductible.


    Your donation to I4EI will expand leadership opportunities to thousands more subsistence farmers. Their actions will improve their farms, their local environment, their daily lives and our climate worldwide.
