Mazda is currently involved in joint research projects and studies as part of an ongoing industry-academia-government collaboration to promote the widespread adoption of biofuels from micro algae growth.

As part of its 'Sustainable Zoom-Zoom 2030' long-term technology development programme, the company is committed to reducing its average 'Well-to-Wheel' CO₂ emissions to 50% of 2010 levels by 2030, and to 10% by 2050.

Expecting that internal combustion engines combined with some form of electrification will still account for some 95% of the vehicles it produces in 2030, and that liquid fuel will remain dominant in the automotive industry until at least 2040, Mazda considers a renewable liquid fuel essential to drastic CO₂ reduction.

When burnt, algae biofuel only releases CO₂ that has been recently removed from the atmosphere via photosynthesis. Mazda thus considers this research to be critical to achieving the carbon-neutrality of cars powered by the internal combustion engine.

Micro algae biofuel has numerous additional positive attributes as a renewable liquid fuel. Algae fuels can be farmed on land unsuitable for agriculture, and can be grown with minimal impact on freshwater resources. It also can be produced using either saline or wastewater, has a high flash point, and is biodegradable and relatively harmless to the environment if spilled.

Improving productivity and reducing costs are fundamental to the widespread future availability of algae biofuels.

To that end, Mazda is lending research-accelerating technical support to the combination of research into genome editing by Hiroshima University and plant physiology by the Tokyo Institute of Technology, which is intended to lead to a breakthrough in these areas.

As part of the 'Well-to-Wheel' initiative, Mazda has also developed a multi-solution approach to reduce overall CO₂ emissions without any compromise to driving pleasure and performance to its vehicles. Ingenious Skyactiv technologies such as i-STOP, Cylinder Deactivation and Mazda's M Hybrid 24V mild-hybrid system are fitted as standard on selected models across the range, while the Mazda3 and CX-30 are offered with Mazda's revolutionary 2.0-litre 178bhp Skyactiv-X Spark Controlled Compression Ignition (SPCCI) petrol engine.

The company will introduce EVs as the optimum environmentally-friendly solution to regions that generate electricity from clean energy sources or restrict certain vehicle types to reduce air pollution.

The new all electric Mazda MX-30 First Edition features an AC synchronous electric motor and a 35.5kWh lithium-ion battery that allows for 50kW rapid charging.

With its unique freestyle doors, ecological materials and right-sized battery giving a range of approximately 201km under the Worldwide Harmonised Light Vehicle Test Procedure, the Mazda MX-30 exceeds the 48km average daily drive of the European customer. The Mazda MX-30 marks another positive step in Mazda's multi-solution approach to reducing emissions following the recent arrival of the innovative Skyactiv-X engine.
