Hiroshi Komiyama's "Vision 2050" is a plan for paving a road to global sustainability. It lays out a path to a sustainable future for humanity that could realistically be achieved by 2050 through the application of science and technology. A prominent Japanese academic and leader in global sustainability, Komiyama draws upon realistic assumptions and solid scientific concepts to create a vision that makes the living standards enjoyed by developed countries today possible for all people by 2050. "Vision 2050" is built upon three fundamental principles increased energy efficiency, recycling, and development of renewable energy sources and the book argues for the technological potential of all three. Specifically, Komiyama envisions a three-fold increase in overall energy efficiency and a doubling of renewable energy resources by 2050. "Vision 2050: Roadmap for a Sustainable Earth" is written to address the concerned citizen as well as to inspire an exchange of ideas among experts, policy makers, industrial leaders, and the general public."
