The CDI Foundation Trust Fund (CDI) represents an emerging concept in Papua New Guinea (PNG) for addressing social change and development. CDI is a non-profit organisation supported by corporations in the petroleum industry aimed at addressing the social needs of rural communities in the provinces within which these companies have invested.

CDI stands for Community Development Initiatives. The CDI Foundation Trust Fund builds upon community development initiatives originally carried out by Chevron Niugini Ltd (CNGL) in the Southern Highlands and Gulf Provinces of PNG since construction of the oilfield and pipeline facilities commenced there in 1990. CDI assumed direct responsibility for these initiatives in 2001 as a non-government organisation (NGO) that can facilitate long term social development well past the life of oil and gas production in the area.

CDI strives to work with the Government and Community to improve the educational, cultural, economic and social well being of the targeted communities by: facilitating self-reliance and self-help to avoid dependency, using participatory approaches to ensure all affected groups take part in the design, implementation and evaluation of programs and activities that affect them, working with and through local and national groups and assist in their institutional strengthening and integrating gender participation and awareness of gender issues into every aspect of program design and implementation to foster equitable participation and benefits for both men and women.
