Per-cup breakdown — emission factors by source
Roasting energy — Idemat 2026RevA calculation
How roasting is calculated: 2.5 MJ natural gas + 0.05 kWh electricity per kg green coffee.
Roasting loss: 18% (green → roasted). Each capsule contains 5.7 g roasted coffee = 6.95 g green coffee.

This tool is intended for screening LCA and early-stage design decisions only. Results are not suitable for EPDs, public environmental claims, or comparisons intended to be disclosed publicly under ISO 14040/44 without independent critical review.
Roasting energy per cup: ~1 g CO₂ — confirmed minor contribution consistent with peer-reviewed literature (Chéron-Bessou et al. 2024, Quantis/Nespresso LCA 2019–2024).
