Die Schurken-Vergleiche

Auch die augenzwinkernden Vergleiche (Privatjets, Kohlekraftwerke …) beruhen auf veröffentlichten Zahlen:

• 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
• Global Energy Monitor — a 1 GW coal plant at an 0.8 capacity factor emits ≈6.3 Mt CO₂ a year
• 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)
• Euromonitor (2017), via National Geographic — about a million plastic drink bottles are bought every minute worldwide
• Coca-Cola’s 2019 Ellen MacArthur Foundation disclosure — 3 Mt of plastic packaging a year, roughly 200,000 bottles a minute
