What carbon data do global brands ask Penang electronics manufacturing suppliers for?
Usually Scope 1 and 2 by site with year and method, renewable share, a target, and increasingly a product footprint for the assemblies you build. Build them from electricity and gas bills, refrigerant logs and component supplier data, and answer every portal with the same numbers.
Typical asks
- Scope 1 and 2 per site.
- Renewable electricity share and how it is sourced.
- Science based or other targets.
- Product footprint per board or assembly.
Product figures
Components, especially chips and PCBs, carry most of an assembly's footprint. Your own SMT and test energy is small but must be shown with its split.
Keep it consistent
Use one data set for all customers and update it yearly. Different numbers in different portals are the quickest way to lose trust.
What Senseible does here
Senseible reads electricity, fuel and refrigerant invoices into a dated, fingerprinted record per site, so the figures a brand asks for trace back to the bills behind them.
