The exemple: carbon fibres, I've been looking for inputs/outputs for cf production and there is no good data available and companies aren't open about sharing their information, but there is an association who avarages data from many companies hence the numbers they disclose are emissions: eq CO2, SOx and NOx. If I want to use carbon fibre produced in japan this data is the most suitable for me, but I dont know if I should put this emissions as input or output, and what are the consequences for other impact cathegories if all I have are emissions, should I only focus on global warming as impact cathegory?
