What percentage of all emissions is accounted for by road transport?

  1. 10%

  2. 15%

  3. 20%

  4. 25%

The correct answer is: 20%

Road transport accounts for approximately 20% of total emissions. This percentage is significant because it highlights the impact that vehicles, including cars, buses, and trucks, have on the overall environmental footprint. Understanding this statistic is crucial for driving awareness around the importance of reducing emissions through various means, such as using public transport, carpooling, or shifting to electric vehicles. The other figures, while they may seem plausible in understanding the broader context of emissions sources, do not accurately reflect the data regarding road transport specifically. Hence, it's essential for learners to grasp that road transport is a major contributor to emissions, reinforcing the need for sustainability practices in transportation.
