Environmental considerations for PVC are only indirectly a concern for the end user as legislation will be regulating any limitations for compounds or use. An example is ban of certain constituents formerly generally applied in PVC compounds, like the heavy metals cadmium and lead. Use of PVC sheathed cables must of course be in compliance with the national or international regulations of the country in question.

Other discussion points related to the general environmental behavior of PVC are often found in the public debate. Key words like "acid rain", "dioxine formation", "pollution with heavy metals", "fertility of man and male animal" and "cancer risk" are popular environmental arguments against PVC. If and how these issues may affect the future application of PVC cables cannot be concluded by 3P.
