Highlights of Environmental Initiatives in FY2002 Environmental Management Development and Design   • Product Environmental Management System   • Improving Fuel Efficiency   • Reducing Exhaust Emissions   • Promoting an Increase in the Number of Vehicles that Meet Both the Ultra Low-Emission Vehicle Level and the 2010 Fuel Efficiency Standards   • Reducing External Automobile Noise   • Clean-Energy Vehicles   • LCA   • LCA of New Models and Models Undergoing Complete Redesign   • New Prius: Unveiled at the New York International Automobile Show Procurement/Production/ Logistics Recycling and Sales/After Sales Automobile Peripheral and Other Businesses Environmental Education/ Communication Special Story Consolidated Environmental Management Environment-Related Awards Received by Toyota Continued Reporting of Environmental Aspects Environmental Chronological Table		LCA of New Models and Models Undergoing Complete Redesign  Toyota carried out LCA on new models and models that underwent complete redesign. In the case of the ist, fuel efficiency was improved by adopting VVT-i and a high-efficiency transmission, reducing air resistance, and designing a more energy-efficient air conditioner. Cleaner exhaust emissions were achieved by effectively controlling a catalytic converter that has superior warm-up characteristics and durability, an air-fuel ratio compensation system, and a fuel evaporation gas suppression system, etc. As a result, the vehicle produces 8% lower CO2 emissions, 63% lower NOx emissions, and 64% lower NMHC emissions than other conventional vehicles in the same class.   ist   •Specification Comparison between the ist and a Conventional Vehicle *Assumes a lifetime travel distance of 100,000km (10 years) and calculations based on the 10-15 Japanese test cycle *In the graph to the left, CO2 value for the conventional vehicle is set at 1, while other values are based on a conventional vehicle NOx value of 1   •ist LCA Results   •Environmental Data for FY2002
