How are these emissions calculated?

We calculate carbon footprints by measuring total greenhouse gas (GHG) emissions and converting them into standard CO₂.

Our methodology is broken down into three key components:

1. Calculation Method: We multiply activity data (such as energy used or kilometers traveled) by verified emission factors established by climate research bodies like the IPCC and ICCT. This converts gases like methane (CH₄) and nitrous oxide (N₂O) into a unified CO₂ value.

2. Coffee Supply Chain Breakdown:
Transport & Logistics: Calculated using granular, highly specific transport data.
Farm Production: Calculated using origin country and certification benchmarks. Production is where the primary climate impact lies: roughly two-thirds ($2/3$) of a coffee's carbon footprint occurs at origin, and choosing organically certified coffee reduces farm-level emissions by a factor of 3 to 4.

3. Greenhouse Gas Protocol: For roasters, these represent Scope 3 emissions—indirect emissions that occur within your value chain.
