The vision of the Foundation is to have a positive impact on the quality of people’s lives. It does this by focussing its assistance on two main areas: the environment and education. This is accomplished primarily through the provision of grants to charitable organizations; the scholarship and bursary programme; the funding of two Professorial Chairs at The University of the West Indies and the Annual Lecture Series. This year’s Lecture helps to highlight our longstanding commitment to preserving and protecting the environment. In 1982 we established the James Moss-Solomon Snr. Chair in Environmental Management, which has been integral in fostering research, innovation and leadership in this important field. Over the past two years the parent company has partnered with the Foundation to contribute $1m annually to the UWI Plastic Bottle Separation and Recovery Project. The funding is used not only for the UWI’s initiatives but also to introduce recycling to our subsidiaries located in Kingston as we foster a culture of environmentally-conscious corporate citizenship. We are aware that much more can be done and our hope is that the Lecture will be a springboard for further change, not only at GraceKennedy but throughout Jamaica and across the Caribbean region. We are confident that this Lecture will continue in the tradition of previous Lectures and will become an invaluable resource for all who seek a deeper understanding of national issues. Copies of the book are distributed to schools and public libraries across the island, an e-book version is available online at www.gracekennedy.com, and the Lecture is streamed live via
