Achieving Cleaner Emissions and Further Reducing VOCs
to Improve Atmospheric Quality Both from Products and Monozukuri (Manufacturing)

100% of Toyota Vehicles Meet or Exceed the Ultra Low-Emission Vehicle Level (U-LEV)

Low-Emission Vehicles as a Percentage of Total Production

Low-Emission Vehicles as a Percentage of Total Production

In FY2009, Toyota increased the number of vehicles that meet the Super Ultra-Low Emission Vehicle (SU-LEV) level, with 75% less emissions than the 2005 Exhaust Emissions Standards in the Ministry of Land, Infrastructure, Transport and Tourism's Approval System for Low-Emission Vehicles. 93.3% of Toyota vehicles produced were certified as meeting the SU-LEV levels, and 100% of all Toyota vehicles produced have been certified U-LEV or better since FY2008. Of gasoline-powered vehicles produced in FY2009, 18 vehicle series in seven of eight new or fully changed models gained new SU-LEV certification, while three vehicle series in one fully changed model were certified SU-LEV, which signify a 50% reduction in exhaust emissions over 2005 exhaust emissions standards.

VOC Emissions from Paints Reduced to an Average of 23g/m²

VOC Emissions Volumes in TMC Vehicle Body Painting Processes (Average for All Lines)

Volatile organic compounds (VOCs) are considered to be one of the causes of photochemical oxidants which contribute photochemical smog. At Toyota, in order to reduce the amount of VOCs emitted during the painting process, less solvent is used in washing processes and a larger percentage is recaptured and deionized water (DI water) is used for washing instead of water borne cleaning solvent. As a result of these VOC reduction programs, total VOC emissions from Toyota body paint lines averaged 23 g/m²┬áin FY2009 (a reduction of 4.7% from the previous fiscal year), which met Toyota's goals.
