How does PVC help to conserve natural resources and combat climate change?

Because PVC is intrinsically a low-carbon material which consumes less primary energy than many other materials and is easy to recycle. 

Also, most PVC products are very long lasting and require a minimum of maintenance and repair. For instance, the service life of PVC water and sewage piping is more than 100 years. And modern cars last many years longer simply because PVC protects the underside from water and corrosion.
