Table 1 indicates the relevance to each stage of the production process for identified legislation. There remain uncertainties as to the potential influence of many legislative mechanisms, and the significance of the interrelation of alternate product components (optic, control, mechanical etc.) on the optimisation of the whole product system

Indication of relevance :

• Primary relevance (tanned rose)- the production aspect of direct relevance to the intended outcome (area of influence) of the legislation reduced energy consumption provides focus on the electronic component specification. • Secondary relevance (orange) – the additional production aspects relevant to the legislation (i.e. optic specification influence on energy consumption) • Tertiary relevance (green) – limited influence on the production aspect • Uncertain (white)
