Answer:
Hybrid
Explanation:
Decreasing engine emissions through hybrid technology that not only protects the environment but also increases fuel efficiency may become the norm
In terms of the trajectory to total CO2 reduction, a transition from gasoline internal combustion engine to full gasoline hybrid can reduce emissions by 34%. As it will take time to increase the supply of full hybrids, there are two routes to short-term CO2 reduction that are viable more quickly.
