last year will account on average for emissions equivalent to 1 million tonnes of carbon dioxide each over their 20-year-plus lifespans, a new report from the planemaker shows.
Boeing aims to "significantly reduce our environmental impact during every stage of a product’s life cycle," Chief Executive Dave Calhoun said introducing the Chicago-based company's first-ever sustainability report on Monday. That consists of 136 million tonnes of emissions directly linked to their operation by airlines, and 22 million tonnes related to the production by energy companies of the fuel used in flight.
Airbus assumed an average 22-year lifespan for its jets. A Boeing spokesman said it assumed 22.8 years for single-aisle aircraft, 21.5 years for twin-aisles and 29.6 years for freighters. Based on Boeing's 2020 delivery data by type, that suggests a weighted average of 24.8 years, Reuters calculates.
For the 806 jets delivered that year, Boeing expects direct lifetime emissions of 560 millions tonnes, or 652 million including fuel production, a spokesperson said.
