Module 5 of 9 · A4 · Precursors in the aluminium value chain
4.Mixing actual and default values
You can use actual data for your own process and defaults for one or more precursors. Your emissions report must then show which precursors used defaults, the values applied and the share of emissions based on defaults.
WATCH OUT Agree with your verifier whether the precursor default is applied with mark-up. The Commission's own worked example applies it, so this example does too.
