187 Ship interior designers already have to contend with fire-load limits in their work. A system similar to this could be instituted so that only a certain amount or volume of non-biodegradable materials would be allowed in any interior design. Alternatively, it has been proposed that an index similar to that already being used for energy labels could help narrow down the choice of materials and products. This type of star rating system could set limits in the form of aggregate sums for each area (flooring, surfaces, ceilings, lighting, furniture etc.) Materials could be scored according to standardised ranking methods, for example their reusability and recyclability as well as their energy performance and durability. The following actions towards more sustainable maritime interiors were proposed by contributors to this report. These actions have not been audited against any initiatives that may currently be underway and not all of these suggestions will be viable or prudent. There is some duplication in this list and there are also sometimes conflicting suggestions – we have avoided removing these issues to maintain the independent approach that we have applied throughout the report. Contributors were overwhelmingly in favour of the establishment of a sustainable maritime interiors industry group, supported by all stakeholders, to take ownership and progress these recommendations and other related industry-wide priorities. Perhaps this task should be our primary focus in the short-term? The following pages detail a checklist for recommended actions towards sustainability.
