Analyzing the Impacts of Global Transport CO2 Emissions Using Multi-Sectoral Tool
The Global Calculator was built to model carbon dioxide (CO₂) emissions in 2050 based on a variety of user selections for different sectors. This paper focuses on the modeling and results relating to the transport sector, which was developed to estimate an accurate base year as well as aid in determining four different Levels of Effort to reduce CO₂ emissions for six levers: passenger demand, freight demand, mode, occupancy and load, electric or hydrogen vehicles, and vehicle efficiency. Level 1 represents minimal effort made in the sector to reduce emissions, while Level 4 represents the maximum effort the sector can achieve. This model shows us that action or inaction in the transport sector can result in an increase or decrease of 20% in CO₂ emissions from what is considered business as usual, the International Energy Agency (IEA) 6 degree scenario. Vehicle efficiency and mode share are very important for reducing emissions from the transport sector, while effectiveness of electrifying the fleet relies heavily on having a green grid. This also provides a global bottom-up model that can be used to compare both lifestyle and technological changes which will impact future emissions.
