With the Product Sustainability Index (PSI), Ford of Europe has introduced a groundbreaking new approach to building greener vehicles. Here’s how it works.

From the earliest stages of a vehicle's development, Ford's PSI tracks the key sustainability elements of a vehicle.

• Life cycle global warming potential (mainly CO2 emissions)
• Life cycle air quality potential (other air emissions)
• The use of sustainable materials (recycled and renewable materials)
• Vehicle interior air quality (including TÜV allergy certification)
• Exterior noise impact (drive-by noise)
• Safety (for occupants and pedestrians)
• Mobility capability (seat and luggage capacity relative to vehicle size)
• Life cycle ownership costs (full costs for customers over the first three years)

In an independent, external study, Ford's PSI has been evaluated as a step which aims to provide a full sustainability assessment and as being compliant with ISO 14040, the international Life Cycle Assessment standard.

The S-MAX and Galaxy were the first models designed with PSI in mind and show improved performance when compared to the previous Galaxy model in all three sustainability areas: environmental, social and economic performance.

Every single future Ford vehicle will be developed with PSI in mind.
