Kilder

Hvert tall på SproutAtlas bygger på en publisert kilde — for det meste fagfellevurderte studier, i tillegg til rapporter fra offentlige organer. Her er alle sammen, bytte for bytte. Hver bytteside lister også sine egne kilder.

Kjøp bedre, bruk lenger i stedet for Fast fashion

• Niinimäki et al. (2020), Nature Reviews Earth & Environment — the environmental price of fast fashion (water, CO₂, textile waste)

Skurke-sammenligningene

• Transport & Environment (2021) — some private jets emit two tonnes of CO₂ per flight hour
• Barros & Wilk (2021), Sustainability: Science, Practice and Policy — a superyacht emits on the order of 7,000 t CO₂ a year, the largest single item in a billionaire’s footprint

• Poore & Nemecek (2018), Science — beef averages ~60 kg CO₂e per kg, the highest-footprint common food
• UK Government GHG conversion factors — long-haul economy ≈0.15 kg CO₂e per passenger-km, so a one-way London–New York seat (~5,600 km) is ≈0.8 t CO₂e
• Saatchi et al. (2007), Global Change Biology — Amazon forest holds ~177 t of above-ground carbon per hectare (≈65 kg CO₂ per m²)
