To also build up on the point, the Nova Check collection is constructed mainly from polyvinyl chloride (otherwise known as PVC), which is why the Nova Check collection is at a lower price point - for the masses.
In the recent few years, Burberry has been trying to go greener for the environment (cutting back on printed materials and going digital). Within that same initiative, it's been realized that the manufacturing of the main components for PVC is very hazardous to our environment.
Protecting the environment > Company profits.

I think this is great that Burberry is taking the initiative to take care of our environment first before thinking about personal profits, unlike other luxury brands (ahem ahem).
