  Greenhouse gas, produced from various industries such as Power,
Manufacturing, Transport, Chemical, or Agriculture, is the major source of
global warming. While the transport industry is among the top three major
contributors, accounting for 16.2% of global emissions. To counter this, many
countries are responding actively to achieve net or absolute zero-emission
goals by replacing fossil fuel with renewable energy sources. In response to
this initiative, this chapter provides a systematic review of the use of
zero-emission vehicles for a specific use case of package delivery. It first
compares different green delivery systems that use unmanned aerial vehicles,
electric vehicles, and fuel-cell trucks for certain weight categories.
Specifically, a coordination of unmanned aerial vehicle and ground-based
electric truck envisions a new paradigm of ground-based zero-emission vehicles
where unmanned aerial vehicles can fly in the air beyond the visual line of
sight empowered by future-generation wireless technologies. The integration of
zero-emission vehicles for package delivery will encounter many challenges in
analyzing, modelling, planning, and designing a green logistics system. This
chapter investigates these challenges in the adoption of zero-emission vehicles
with the existing research issues from a technical, environmental, economic,
and political point of view. In addition, this study also sheds a new research
perspective on artificial intelligence and integrated solutions for
zero-emission deliveries.
