James G. Speight, PhD, is a senior fuel consultant and Visiting Professor at the University of Trinidad and Tobago and Adjunct Professor of Chemical and Fuels Engineering at the University of Utah, USA. He is recognized internationally as an expert in the characterization, properties, and processing of conventional and synthetic fuels and has more than 40 years of experience in the process industries. He is the author of numerous books and papers, the senior editor on the Journal of Sustainable Energy Engineering, and he has won numerous awards and distinctions.

M. R. Islam, PhD, is a world-wide consultant on environment and energy-related issues. Dr. Islam is known as the most published engineer in the world. He is credited to have coined terms, such as "green petroleum" and "sustainable petroleum development" at a time when "sustainable petroleum" was considered to be an oxymoron. Dr. Islam's most notable contributions are in the areas of sustainability, environmental integrity, and knowledge modeling, on which topic he has written dozens of books and over 700 research papers.
