3.2.1 Composition of GHG emissions
In this video we will be looking at the global trends in transportation related emissions. Next we discuss what factors contribute to transport emissions thereby allowing us to explore some potential means of reducing them.
Key takeaways:
- Global GHG emissions from the transport sector have more than doubled since 1970, and have increased at a faster rate than any other energy end-use sector.
- Reducing transport emissions will be a difficult task given the increases in demand and the fact that it takes years or even decades to build infrastructure, implement policies, and enact behavioural changes.
- The GHG emissions from transport can be decomposed into four factors: system-infrastructure modal choice, fuel carbon intensity, energy intensity and activity.
