Achieving Zero CO2 Emissions
Let's say the government wants drastic change and decides to ban all CO2 releasing Internal Combustion Engine (ICE) vehicles and allow only Battery Electric Vehicles (BEV) on the road. Can the transport sector achieve zero CO2 emissions in the country if all private and commercial vehicles are BEV?
The answer is no.
Normally when we talk about CO2 emission, we usually look only at what comes out from the vehicle tailpipe. With that in mind, BEVs have no tailpipe emissions, but when considering the energy production (coal, oil-based, natural gas) to recharge them, they also emit CO2.

We can only achieve zero CO2 emission using the BEV when all power generating plants use clean energy sources such as solar, wind, hydro, geothermal, biomass, and nuclear.
Vehicle Electrification with xEV
Vehicle Electrification is essential, including various types of electrified vehicles, which includes Hybrid Electric Vehicle (HEV), Plug-in Hybrid Vehicle (PHEV), Battery Electric Vehicle (BEV) and Fuel-Cell Electric Vehicle (FCEV). Toyota calls them “xEV”. Here in the Philippines, you may realize that Toyota has promoted all technological developments for xEV. That is because they believe that responding to the diversified energy sources such as biofuel, electricity, and hydrogen, will lead to proper energy-mix.
To sum it up, the use of energy sources should truly match the energy situation in the country. We need to consider a wide comprehensive approach to products, technology, and infrastructure.
The Hybrid Electric Vehicle
|The difference between the internal-combustion engine (ICE) vehicle and the Hybrid Electric Vehicle (HEV).|
When the vehicle is stopped, the engine is not running. When the vehicle starts moving to mid-speed range, it is driven only by the electric motor.
|The hybrid electric vehicle has two power sources, an Internal Combustion Engine and an Electric Motor.|
Under constant speed condition, both engine and motor will be optimally used. When there is surplus engine power supply, it also generates electricity to charge the battery.

The key core components of an HEV are the Electric Motor, Battery, Inverter, and the Power Control Module.

Toyota Prius Hybrid Evolution
Toyota has been continuously improving the fuel efficiency of its HEV model since its 1st generation Prius. And now, the 4th generation of Prius has good fuel efficiency at 40.8 km/L in JC08 test mode, which is an improvement of 25% compared to the 3rd generation.

TMP was the first automotive brand to make the HEV available to the Filipino with the introduction of the second generation Prius in 2009.
Hybrid Electric Vehicle or Battery Electric Vehicle?
HEVs are widely known to be more fuel efficient than traditional petrol engines, and their self-charging capability requires no additional infrastructure to be built in order to seamlessly start the transition. These practical and proven factors make Toyota hybrids the viable option as the Philippine transportation alternative for a sustainable future.

Toyota Hybrid Electric Technology Conference
Toyota Motor Philippines (TMP) reinforced its call to position vehicle electrification as one of its long-term solutions for a greener and more energy-efficient local automotive landscape.
As one of its initial steps, TMP launched recently the Toyota Hybrid Electric Technology Conference with the theme “TOWARD SUSTAINABLE MOBILITY”. The event was jumpstarted by TMP in an effort to openly discuss the consequential effects of HEVs in the local and current landscape, aimed at promoting wider adoption of hybrids as the future of local transportation.
Toyota aims to propel the country into this paradigm shift through its lineup of self-charging Hybrid Electric Vehicles (HEV). Toyota officials and tech experts suggest that hybrid is currently the most suitable electric vehicle platform for the local market.

In the conference, TMP highlighted the importance of partnership and mutual understanding between the public and private sectors in order to adapt to quickly changing times.
“Toyota has a whole range of electrified vehicle (xEV) technology that can help achieve sustainable mobility goals. But xEV popularization depends on many factors and varies by market. Based on current Philippine conditions, it is most appropriate to start with HEV popularization in order to accelerate the reduction of emissions and fuel consumption,” said TMP President Mr. Satoru Suzuki.
TMP’s stance on hybrid electric technology is strongly supported by the environmental philosophy of the Toyota Environmental Challenge 2050, aimed at eliminating Toyota’s carbon emissions by the next three decades. “Toyota is committed to be a part of the solution ahead of future challenges with “Toyota Environmental Challenge 2050,” said Vince Sotto, Executive Vice President of Toyota Motor Asia Pacific. “Towards this direction, Toyota challenges ourselves to achieve not just zero environmental impact, but a net positive impact on Earth and Society, as well,” Socco added.
