Toyota employs its own standard to measure each new vehicle's environmental "footprint." Toyota's Eco-VAS, or Eco-Vehicle Assessment System, is a tool for predicting and reducing the environmental impact of its vehicles. It also measures the energy required in a vehicle's production and operating stages, but goes beyond analysis to provide a framework for design changes that improve environmental performance. Toyota's engineers use Eco-VAS all through the process of design and development and leading to production -- measuring a vehicle according to six critical standards: fuel efficiency, exhaust emissions, external vehicle noise, lifetime environmental impact, recyclability and the reduction of substances of concern.
