# What carbon data do global brands ask Penang electronics manufacturing suppliers for?

Canonical: https://senseible.earth/answers/penang-ems-supplier-carbon-data-request

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.
