Method and data
Each swap replaces one typical serving using global average impacts per kilogram from Poore & Nemecek (2018), multiplied by 52 weeks. Pulses are counted at their dry weight, which overstates their footprint per serving and keeps the savings conservative. The driving comparison uses 0.17 kg CO₂e per kilometre.
