segundo os cálculos do cientista climático Peter Kalmus
Kalmus, P., ‘Today the world’s biggest carbon capture facility turned on’, Twitter, 9 de Setembro de 2021, https://techstory.in/orca-worlds-largest-carbon-capturing-facility-just-opened-in-iceland/, https://www.businessinsider.nl/the-worlds-biggest-carbon-removal-plant-just-opened-in-a-year-itll-negate-just-3-seconds-worth-of-global-emissions/.Falamos em transformá-los em algumas semanas.
Todos os anos emitimos actualmente cerca de 42GT de CO2. Isto significa cerca de 0,8GT de CO2 por semana. Como exemplo, o roteiro da IEA Net Zero 2050 (a partir de 2021) estima que a captura global de CO2 até 2050 seja de 7,6GT de CO2 por ano. Isto equivale a cerca de 9,5 semanas dos níveis de emissão actuais. A captura de CO2 no ano 2050 apenas pela Direct Air Capture (DAC) é estimada em “um pouco menos de 1 GT”.
