CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION

Description

Y02T encompasses climate change mitigation technologies applied to transportation systems, covering innovations that reduce greenhouse gas emissions and energy consumption across all modes of transport. This subclass includes electric and hybrid vehicles, alternative fuels (such as biofuels and hydrogen), improved combustion engines, aerodynamic enhancements, lightweight materials, and infrastructure for sustainable transportation. It also extends to public transport optimization, fleet management systems, and modal shift technologies that encourage lower-emission travel options. As a cross-sectional tagging classification within the Y scheme, Y02T serves to flag environmentally significant inventions for rapid identification rather than providing primary classification for transport patents.
