(b) major changes in national policies and in general industrial development, and their potential impact, which would be likely to cause significant changes in long-range transboundary air pollution;
(c) control technologies for reducing air pollution relevant to long-range transboundary air pollution;
(d) the projected cost of the emission control of sulphur compounds and other major air pollutants on a national scale;
(e) meteorological and physico-chemical data relating to the processes during transmission;
(f) physico-chemical and biological data relating to the effects of long-range transboundary air pollution and the extent of the damage 1) The present Convention does not contain a rule on State liability as to damage. which these data indicate can be attributed to long-range transboundary air pollution;
(g) national, subregional and regional policies and strategies for the control of sulphur compounds and other major pollutants.
