onto the market because i think if i'm right technically although you have to do a lot of testing to get a stove on the market once it's out there uh there's no requirement for for retesting of

Calvin MayGUEST
So surveillance is apparent in things like the ready to burn contract for wood-based fuels and solid manufactured fuels.

Calvin MayGUEST
And again, a lot of the research we do with suppliers shows that there are large thinking in terms of gaps and things on things like surveillance.

Calvin MayGUEST
yeah i think with innovation kicking off with appliance technologies there's things like catalytic converters being put into appliances now people manufacturers are trying to make stoves as clean as possible so innovation really does take hold and it is quite a very very fast process so it's about making sure that those changes don't impact things too much and we're confident and we're confident that we can go to government officials to show them when appliances do change it's not having a detrimental impact on our air quality emissions so i'm fully in favor of supporting a surveillance regime we just need to make sure that it's tailored in the right way it supports all elements of the industry it supports small and medium enterprises so there are a number of options that we have we can even mandate five yearly testing or we could go for a halfway hybrid house where we could look at something like a fpc which is a factory production control procedure where assessors actually go to manufacturing facilities and make sure that what's being manufactured on the product line marries up with things like their quality processes the standards that we utilize every day and makes an assessment on that it's a it's a lot cheaper it's a lot less investment so again it's just making sure that um that we do it in the right way that supports the industry in meeting compliance really

Calvin MayGUEST
So they're looking at sort of similar A to G, A to C rating system like you see on fridges in the refrigeration industry.
