In video 3.3 we will take a closer look at how transport emissions can be broken down by different modes of transport. We will then compare a few countries to see how their transport sector emissions differ. By comparing different countries we can gain a better understanding of the complexity of analysing emissions from transportation.

Key takeaways:

1. Globally, road travel accounts for the majority of transport sector emissions.
2. While examining figures and graphs that show us trends, percentages, and magnitudes of greenhouse gas emissions, we have to remember to refrain from directly comparing regions as they often significantly vary by population size and land use.
3. Transportation sector emissions are usually one of the largest contributors to the overall emissions of a country, regardless of the geographical location.
