2019/10/17 6 Importance of Circular Economy in Japan: Perspectives from Tokyo Metropolis • From life cycle perspective, waste management sector of Tokyo Metropolis will reduce 6.86 million tons CO 2 e in 2011, 1.12% (61.1 million tons) of total CO 2 emissions. • Indirect and direct carbon emissions contributed 1.77 million and 2.83 million tons to the carbon footprint, respectively; the carbon emission reduction from waste recycling is enormous, which is 1.15 million ton CO 2 . Life cycle carbon footprint of waste management sector, 2011
