As a good corporate citizen, IIF feels equally responsible for the impacts that may come from the development of infrastructure projects, however small the impacts may be.

To date, IIF continues to work together with all clients to minimize those impacts, by conducting intensive and effective action guided by IIF's eight principles of sustainability that were carefully formulated by the founders of the company.

These eight principles covers Social and Environmental Management System (SEMS); Labor and Working Condition; Pollution Prevention, Abatement and Climate Change; Community Health, Safety & Security/DAM Safety; Land Acquisition and Involuntary Resettlement; Biodiversity Conservation and Sustainable Natural Resources Management; Indigenous People (IP); and Cultural Property and Heritage.

In the Cikopo-Palimanan toll road construction project, IIF along with one of its client, PT Lintas Marga Sedaya, conducted a social program for the local community by empowering them to cultivate and trade mushroom and bamboo, along with providing entrepreneurial and business skills such as forming cooperative, grocery trading, and goat farming.

IIF also participated in several seminars related to sustainable financing, such as Green Planning and Budgeting Strategy for Indonesia's Sustainable Development and OJK Green Sustainable Financing. In addition, IIF also provides donation as its contribution to the underprivileged people.
