What carbon data do EU drinks brands ask Monterrey glass container makers for?
Glass is not a CBAM good, but brands counting Scope 3 ask for a figure per tonne or per bottle. It covers furnace fuel, CO2 released from soda ash, limestone and dolomite, electricity, and the cullet share, which lowers both fuel and process emissions.
What goes into the figure
- Natural gas or fuel oil burnt in the furnace.
- Process CO2 from carbonates in the batch.
- Electricity, including any electric boosting.
- Packaging and transport if the buyer asks for delivered figures.
Why cullet matters
Recycled glass melts at a lower temperature and carries no carbonate, so every point of cullet lowers both fuel and process CO2. State the cullet share with the figure.
Give two units
Per tonne of glass for comparison, and per container using its weight, so the brand can fit it into its product footprint.
What Senseible does here
Senseible reads gas, fuel and electricity invoices into a dated, fingerprinted record per site and keeps lab reports and production logs beside them, so each figure can be traced to its documents.
