Rayban Sunglasses

It is summer. Your old sunglasses are a mess.. the glass is full of scratches and after asking about the possibility of repairing them, you finally decide that it is time to buy a new pair.

After trying many models, the final decision is between 2 Rayban  models: Aviator and Wayfarer.

 

Instead of choosing according to economical or esthetical reasons, you have decided to get the most environmental friendly one. You are lucky, since both models have an Environmental Product Declaration under the EPD International system: www.environdec.com

 

Here you are a summary of the results that you can find checking both studies:

 

- For both:  The declared unit is represented by a pair of sunglasses as delivered to the final costumer, i.e. with the sunglass case and cleaning cloth. Packaging is included in the declared unit, as it allows fulfilling the functionality of the product.

 

AVIATOR EPD SUMMARY:

 

 

 

 

WAYFARER EPD SUMMARY:

 

When using a methodology called Ecoindicator 99 we can obtain an aggreggated indicator. In those EPDs the total environmental of the two models was:

 

	Cradle-to-Gate Life Cycle ECOINDICATOR 99  (pt)
AVIATOR	0,345
WAYFARER	0,296

IN CONCLUSION, it seems that the WAYFARER model is more environmental friendly that the other model due to its lower non renewable resources consumption and electricity consumption during the manifacturing (check the rest of the EPC for more details).
