Toyota Motor Corp. said it is targeting a 90 percent reduction in emissions from its new vehicles by 2050 as it seeks to build on the success of its hybrid autos.

The maker of the hydrogen-powered Mirai sedan said Wednesday it aims to deliver more than 30,000 fuel cell vehicles annually by around 2020. It also set a goal to reach more than 15 million cumulative deliveries of hybrids in the same span.

"The beautiful, diverse earth is being lost at a speed where the pace of past innovations is not keeping up," Chairman Takeshi Uchiyamada, known as the father of the Prius, said at a forum in Tokyo. "In order to be there for the global environment, we believe it is important to take up new challenges with a vision for 20 and 30 years ahead."
