The Institute for Sustainability Africa (INSAF) has created significant contributions to socio-economic development in Zimbabwe through the role of the private sector. Since the founding in 2010 Initially as Centre Environmental Accountability (CENAC) and transformation in 2012 to ‘Institute for Sustainability Africa (INSAF), the Institute has made great strides in contributing to national and international developments around sustainability, sustainable development, climate change, and private sector peace-building initiatives. The Institute was behind the first internationally compliance sustainability report from Zimbabwe in 2014 which demonstrated how a private company had contributed economic development, environmental stewardship, social development and governance. Since 2014, INSAF has been working with close to 20 large listed companies in Zimbabwe in the finance, manufacturing, mining, real state, retail and agro-based companies.

We have also contributed to international research in UK and The Netherlands. Our Chief Executive continue to play a significant role in the review of international journals like the Sustainability Accounting and Management Policy Journal. The Institute continue to make significant strides in raising awareness of sustainability as developments strategy which requires African countries to integrated economic, environmental, social and governance aspects into their economic and development model. To this effect, the Institute was instrumental in developments of 2 research papers included in the National Competitiveness Report 2016 for Zimbabwe. The Institute for Sustainability Africa (INSAF) has been emerging as strong think-tank from Africa in regional and international conference to share though leadership.
