Commercial aviation accounts for about 3 percent of all CO2 emissions globally, and in the absence of emissions control efforts, this percentage is expected to continue to grow. In response, market players are working to switch to alternative energy sources, with new fuels that could contribute 65 percent to the 2050 net-zero goals.

Alternatives to traditional jet fuel include hydrogen and electricity, as well as sustainable substitutes such as synthetic sources and nuclear power. This report examines innovations in new fuels and other areas and looks at the contribution the aviation industry can make to reducing emissions.

The paper examines the impact of greenhouse gas emissions generated by cities, focusing on the role of transportation. Cities are responsible for 70 percent of global greenhouse gas emissions, about one-third of which can be attributed to transportation. Excessive use of private vehicles and low uptake of public transportation are key drivers of urban pollution, so managing traffic congestion to develop smart and sustainable cities is critical.

The paper also highlights the growth of the global smart mobility systems market, which leverages wireless technologies, sensors and traffic data analytics to provide decision support. Artificial intelligence, big data and cloud computing have the potential to further enhance the impact of intelligent transportation systems by enabling efficient use of data in urban transportation planning and management.
