Our world faces many challenges, from climate change and air quality to energy efficiency and security. Toyota, after leading the world with the introduction of its first zero-emission fuel cell electric vehicle (FCEV) in 2014, has now taken hydrogen technology to another level with the new generation Mirai.
The years a vehicle spends on the road are the longest stage in its life cycle and the most critical in terms of its impact on the environment. We are constantly seeking new and better ways of minimising that impact, supporting our New Vehicle Zero CO2 challenge.
Far more than an eco-car, the new Mirai pushes the boundaries of hydrogen power and reveals the potential of Toyota’s fuel cell technology. With its hydrogen fuel cell-powered engine, it emits only heat and pure water when driven.
Thanks to its new platform, it is able to carry more hydrogen fuel on board, so it easily reached the target of a 30% increase in its driving range.
The new Mirai can be driven up to 650 km on full tanks, using only 0.79 kg of hydrogen per 100 km*.

When it comes to finding ways of reducing CO2 emissions, we look at a vehicle’s entire life cycle, from design and production, through customer ownership and driving, to ultimate disposal and recycling. This scrutiny is helping us meet our Life Cycle Zero CO2 challenge.
We try to develop each new model in a way that will deliver better environmental performance than its predecessor.
We assess each car’s overall environmental impact in accordance with the international standard ISO 14040/44. You can see the results for the new Mirai in the graph below.
We are committed to making our manufacturing more environmentally efficient as well, reducing CO2 emissions, minimising waste, conserving natural resources and recycling and reusing wherever we can.
We are also constantly streamlining and simplifying our manufacturing processes, moving us towards our Plant Zero CO2 goal.
The Toyota plant where Mirai is produced uses 100% renewable electricity on the production lines for the vehicle and its electrified system parts, including the high-pressure hydrogen tanks and fuel cell stacks. As a result, CO2 emissions from production have been drastically reduced.
The Toyota Water Usage Optimising policy is our commitment to finding ways of consuming as little water as possible in manufacturing (water quantity). It also ensures that any wastewater we produce is treated before it returns to the receiving environment (water quality).
The new Mirai is manufactured at a sustainable plant that aims to make a significant contribution to our Optimising Water Usage challenge. Quantity and quality measures are carefully applied, using new methods for saving water and technologies for treating wastewater.
Through our Resource Recycling challenge, we focus on the efficient use of resources in all areas of our business, in particular the parts and materials used to make our vehicles. Raw materials are a finite resource, so we are constantly researching ways to help build a more resource-efficient economy.
The use of aluminium in vehicle production is increasing, as it provides a simple, safe and effective way of increasing performance and reducing emissions while maintaining, or even improving safety and durability.
Toyota has developed a method for recycling scrap aluminium from its production processes, working in co-operation with our material suppliers. We are pleased that recycled aluminium from this new initiative is being used for the first time in bodywork parts for the new Mirai.
Our challenge to achieve Harmony with Nature is not just about protecting the world around us. It is about improving the environment, creating new habitats for plants and wildlife, fostering biodiversity and creating a sustainable society.
The Mirai manufacturing facility is a member of a working group whose goal is to protect biodiversity, with a focus on reforestation. The group has expanded its activities, involving businesses, local communities and government bodies. Toyota employees from the Mirai plant have planted approximately 23,000 saplings*

Kingfishers and dragonflies inhabit a rice field biotope which uses treated wastewater from the plant. We have been conducting activities to help enrich the environment, resulting in an increase in the number of migratory dragonfly species found on the site from six to 38.
