Global transportation sector COâ‚‚ emissions 2000-2022, by sub sector
Global transportation-related emissions increased by *** percent in 2022 to nearly *** metric tons of carbon dioxide (GtCOâ‚‚). Although emissions from transportation have increased by roughly *** MtCOâ‚‚ since 2020, they remain below pre-pandemic levels.
Since 2000, global transportation emissions have risen by almost ** percent, and now account for around ** percent of total global COâ‚‚ emissions.
