This paper explores the engineering and technology management, and business management literature on green innovations, green investments and green venture capital by using bibliometric analysis and presents the trends in the scholarly literature and professional publications on these areas from 1990 to 2009. The 1990 to 2009 period, with more than five million publications, is analyzed by using the Fisher-Pry model. Projections are made for publication trends on the basis of Fisher-Pry model forecasts. The analysis indicates the emerging and rapid development stages for green technological innovations and green investments in global markets. The paper introduces a methodological approach to forecast the growth of publications as a means of understanding the trends in the increasing emphasis on sustainability in engineering and business publications.
