Definition of the functional unit in terms of articles or coated area, with statements on performance (including durability) is necessary. - A system approach is preferred, which takes account of multiple coats, and pre and post treatments (e.g., in service replacement/repair). - A fair basis for comparison is needed for a credible study, attention must be given to data quality issues. - Emissions are best grouped according to major contributory cause (sub-system/process). - Where trade-offs are identified, emission control options are difficult to justify and need to be approached with caution. - Steps taken to reduce certain emissions will not increase others, E.g., containment ; these changes are easy to justify. - Environmental burdens from high-solids and wtaer based coatings tend to converge as solids levels increase, differences become less significant. - Cost benefit analysis indicates that high solids systems should be seen as an end-point technology, not as a stop-gap.
