Toyota, one of the leading manufacturers in hybrid and fuel cell technologies, has announced what they call a radical environmental plan. Called the Environmental Challenge 2050, Toyota plans to gradually phase out conventional gas and diesel engine in favor of alternative power sources by 2050.

Environmental Challenge 2050 sees Toyota further developing technologies for hybrid, plug-in hybrid, electric and fuel-cell vehicles. As part of Toyota's aim for the 35-year plan, the company targets 1.5 million hybrids and more than 30,000 fuel cell vehicles sold annually by 2020. At the moment, Toyota sells various models of the Prius, hybrid variants of their popular models and the hydrogen powered Mirai Fuel Cell Vehicle (FCV).

Toyota's Environmental Challenge timeline

Toyota says that they are “pushing for further advances related to electrified powertrains”. The company is looking for ways for plug-in hybrids and fuel-cell vehicles getting longer ranges and will gradually move into pure electric power by 2030 onwards, along with a mix of FCV's. Toyota has released a timeline of when the transition from one powertrain to another will begin. While there are no full details on what specific technologies will be used, the company said that they aim to nearly triple the energy density of current high-capacity lithium-ion batteries.

Apart from their cars, Toyota is also aiming for factories and infrastructures with zero emissions. The Japanese car maker will be talking to governments and businesses to further spread the advantages of fuel cell and electric power.
