Canon launched its study on LCA in early 1990’s and has disclosed eco-label type III for copying machines, inkjet (IJ) printers, laser beam printers and cameras since 1999.
In the case of copying machines, life cycle CO2 emission has been reduced by 60% mainly due to the energy conservation technology. In the case of IJ printers, about 7% has been reduced.
Next, the eco-efficiency considering the product value is evaluated for IJ printers. The product value is evaluated by five functions such as “kind number of inks” and “Number of nozzles”. The eco-efficiency of the IJ printer in 2003 was 3.44 times higher than that of 1999.
In 2003, we set the overriding indicator “Factor 2” as our vision for 2010. The Factor is defined as: Eco-efficiency (target year) / Eco-efficiency (base year); Eco-efficiency is defined as: Canon group sales / life cycle CO2 emissions of all products at Canon group. In 2004, the factor increased up to 1.30.
