To play our part in moving the world towards a more sustainable future, we’ve developed a revolutionary approach to designing and building our vehicles. It’s called the Product Sustainability Index (PSI).

PSI is compliant with ISO 14040 – the international Life Cycle Assessment standard. From the earliest stages of a vehicle's development, key sustainability elements are measured. These are:

• 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)

The first models we designed and built using PSI were the S-MAX and Galaxy. Since then, every Ford has been developed with this radical new approach in mind.
