Toyota Australia says it will provide a portfolio of drivetrain options in the future, including battery-electric vehicles (BEVs) to help all types of customers reduce their carbon footprint.

President and CEO Matthew Callachor said the continued development of a full line-up of electrified passenger and commercial vehicles will support the diverse needs of Australian drivers, no matter their location or lifestyle.

He said Toyota's diverse portfolio approach to electrification includes hybrid-electric (HEV), fuel-cell electric (FCEV), and plug-in hybrid-electric (PHEV) in addition to BEVs - all of which have been under development by Toyota Motor Corporation for many years.

It could also involve technologies such as internal combustion engines running on green hydrogen or other carbon-free fuels.

"We will evaluate different options and introduce them as appropriate to help our customers on their journey to zero emissions, ensuring no-one is left behind," Mr Callachor said.

"In a country as diverse as Australia, we need to offer diverse options that - for example - account for different energy sources as well as large differences in customer usage and needs," he said.

"In addition to our own plans for introducing a wide range of electrified vehicles, including BEVs, Toyota has also been sharing our electrification patents, including for HEVs, for more than 10 years.

"Right now, due to their popularity and record sales in Australia, Toyota HEVs provide a significant benefit in reducing the amount of carbon entering the atmosphere. They are reducing more emissions, sooner, than BEVs alone."

Mr Callachor's comments following the global company's announcement of plans to introduce 30 new models and sell 3.5 million BEVs a year by 2030.

He said the record 65,491 HEVs sold in Australia last year - led by RAV4 with 25,850 hybrids - are making a significant contribution to cutting emissions.

HEVs accounted for 29.3 per cent of Toyota overall sales in 2021, including more than half of all the year's sales of Corolla, Camry, Yaris Cross, RAV4 and Kluger.

Local buyers have now bought a cumulative total of 242,272 HEVs since the first Prius was released in 2001.

"According to our calculations, those 240,000 hybrids have had the same impact on reducing CO2 as approximately 72,000 BEVs," Mr Callachor said.

"Yet the volume of batteries we've used to produce these hybrid-electric vehicles is the same as we'd need for just 3,500 BEVs," he said.

"In other words, we can say that the batteries needed for 3,500 BEVs have been used to achieve the CO2 emissions reduction effect of 72,000 BEVs.

"It means that HEVs are an extremely effective way of reducing carbon emissions today - and doing so at a comparatively affordable price."

Mr Callachor said the technologies for Toyota's HEVs, developed over more than 20 years, involved reductions in carbon emissions due to the smart deployment of available batteries.

"If you're recharging a 400km BEV every night for an average round-trip commute of around 40 kilometres, then you're not getting any carbon-reduction benefit from 90 per cent of the battery cells," Mr Callachor said.

"If we put those unused batteries to use in other electrified vehicles, we could prevent far more carbon from entering the atmosphere," he said.

"We cannot assume that 'one size fits all'. Even if the best choice for the average person someday becomes a BEV, it will not be the best way for every person to reduce carbon emissions.

"Distributing every battery cell so that we get the maximum benefit means putting them into appropriate electrified vehicles including HEV, PHEV and FCEV vehicles... not just into a smaller number of BEVs.

"We are absolutely committed to providing our customers with a range of affordable and practical options with technologies that support a more sustainable future," Mr Callachor said.
