The environmental, health, and social equity impacts of vinyl throughout its life cycle – from production to use to disposal – make it the worst plastic for the environment and the antithesis of a green building material.

Vinyl is the only plastic, and the only major building material, made from high volumes of chlorine – chlorine gas, that is. Thus there is an unfortunate domino effect tied to vinyl’s chlorine content (which in final products can exceed 50% by weight) that is not present in the life cycles of alternative materials. In fact, vinyl production requires consuming in excess of 40% of the chlorine gas produced in this country. That is the largest use of the gas in the world. By comparison, 5% of the nation’s chlorine gas is used to disinfect water – and that includes sewage treatment....
