Global CO₂ Emissions from Light Duty Vehicles
In 2022, global carbon dioxide (CO₂) emissions from cars and vans rose by approximately 1.4% compared to the previous year, reaching 3.53 billion metric tons (GtCO₂). This increase marks a continuation of the emissions trend from light duty vehicles, which have grown by 12% overall between 2010 and 2022.
Historical Emissions Trends
The historical data shows a steady increase in CO₂ emissions from the transportation sector:
- 2010: 3.14 GtCO₂
- 2011: 3.13 GtCO₂
- 2012: 3.17 GtCO₂
- 2013: 3.27 GtCO₂
- 2014: 3.31 GtCO₂
- 2015: 3.42 GtCO₂
- 2016: 3.5 GtCO₂
- 2017: 3.55 GtCO₂
- 2018: 3.59 GtCO₂
- 2019: 3.61 GtCO₂
- 2020: 3.2 GtCO₂
- 2021: 3.48 GtCO₂
- 2022: 3.53 GtCO₂
Key Observations
- The overall trend shows a 12% increase in emissions from 2010 to 2022.
- A significant drop occurred in 2020, likely due to global pandemic-related restrictions.
- Emissions quickly rebounded in 2021 and continued to rise in 2022.
The data highlights the ongoing challenge of reducing CO₂ emissions from the transportation sector, particularly from light duty vehicles. As the world continues to grapple with climate change, understanding these emission trends is crucial for developing effective mitigation strategies.
