Based on the Mazda Green Plan 2020 Mid-Term Environmental Plan, Mazda is pressing forward with environmental initiatives, with its sights set on 2020.
Approach on the Mazda Green Plan 2020
Based on the “Philosophy and Policies” for environmental initiatives, being premised on “Mazda’s Vision of a Future Society and Its Relationship with Vehicles” , the plan is developed, centering on the following three main perspectives.
Approach on the Mazda Green Plan 2020
I. Themes to Be Resolved in the Future
Mazda considers the following as issues that both customers and society expect automakers to make positive contributions toward:
- 1. Energy- and Global-Warming-Related Issues
Undertaking measures to reduce CO2 emissions over the entire life cycle of a vehicle.
- 2. Promoting Resource Recycling
Reducing waste from vehicles, the vehicle manufacturing and shipping processes, and disposal of end-of-life vehicles, as well as actively promoting the comprehensive recycling of resources.
- 3. Cleaner Emissions
Reducing various emissions/waste (aside from CO2) from vehicles and manufacturing processes, especially emissions with highly adverse environmental impacts.
- 4. Environmental Management
Develop environmental management throughout the entire Group and supply chain.
II. Mazda’s Initiatives (two categories)
- a. Vehicles and vehicle technology
Contributing to a reduced environmental impact through products and technology
- b. Manufacturing, Logistics, Office Operations, Social Contributions, etc.
Contributing to a reduced environmental impact through all activities (excluding those related to products and technology)
III. Consideration of the Entire Vehicle Life Cycle
Mazda is making efforts to reduce environmental impact throughout the entire product life cycle. Around 75% of CO2 emissions occur over the period from customer use to disposal – an overwhelming percentage of overall emissions.
- ■ Manufacturing and logistics (materials manufacturing, and vehicle manufacturing): accounts for around 25%
- ■ Product use and disposal (use by customer, maintenance, disposal and recycling): accounts for around 75%
Mazda’s Vision of a Future Society and its Relationship with Vehicles
Around 2050: A sustainable society that aims for low-carbon, recycling-oriented, and coexisting in harmony with nature
The 2015 United Nations Climate Change Conference (COP 21) adopted the Paris Agreement, which aims to hold the future increase in the global average temperature to below 2°C and to pursue efforts to limit the temperature increase to 1.5°C compared to the status before industrial revolution. The world is seeing an acceleration of decarbonization in energy toward the realization of a low-carbon society.
This movement enables the combination of a sustainable society that values recycling in order to effectively use limited resources and one that also coexists in harmony with nature, as well as allowing for the stable continuation and progress of humankind. Specifically, they are: a society with greater use of renewable energy sources such as solar power, wind power and biofuels, as well as non-CO2-emitting hydrogen, and a shifting away from carbon energy; a society with improved resource behavior and a diffusion of activities based on the three Rs (reduce, reuse, recycle), enabling efficient and continued use of resources over their entire life cycle; and a society that allows the use of water sources, ecosystems and forests into the future as natural capital.
Regarding vehicles, demand the world over has diversified to include preferences based on regional needs, vehicle characteristics, fuel performance and characteristics, and other factors. This demand profile will only grow more complex in the future.
A multi-solution approach is needed to respond to these diverse demands. Mazda’s expectation is that greatly improved internal combustion engines, alternative fuels such as natural gas and biofuels, and new types of vehicles that do not emit CO2 by using energy sources such as electricity and hydrogen, and other such innovations, will provide those solutions. Going forward, Mazda believes it is necessary to push the limits of what is possible as the Company carefully plots the direction for its brand and technologies.
Around 2020: A low-carbon society in which CO2-reducing technologies have become widespread
Around 2020, Mazda sees society on the way toward achieving a sustainable society while still maintaining the use of fossil fuels (oil based fuels, etc.) as its basic energy source. From energy security viewpoint, we expect the evolution of efficient fuel-use-technology for diverse fuels meeting with unique characteristics of each market/country, and the further introduction of low-carbon technology for several kinds of fuel/energy (electricity, gas, etc.) /materials/products covering all life-cycle processes (from production to consumption by users). Many products and services will be evaluated based on their environmental performance throughout their life cycle.
Regarding vehicles, highly efficient internal-combustion engines—such as gasoline and diesel engines, using liquid fuels (oil, biofuels, etc.), which account for most of the energy for mobility due to their high energy-preservation characteristics—will mainly be used as a base, and additional innovations that contribute to increased fuel economy, such as electric device technologies (idling-stop systems, regenerative braking, hybrid systems, plug-in hybrid systems), highly efficient transmissions, and reduced vehicle weight will also be implemented.
Moreover, technological innovations to support combustion technologies corresponding to diverse fuels and the use of natural gas or biofuels that emit less CO2 are also expected. At the same time, electric vehicles will be introduced as an optimal form of mobility in regions where low-carbon energy can be supplied, such as power generation using renewable energy. On top of these trends, large-scale approaches such as reducing traffic congestion in urban areas will contribute toward the greater goal of realizing a low-carbon society
Life Cycle Assessment (LCA)
Mazda adopts LCA, a method for calculating and evaluating the environmental influence of products across its entire life cycle of vehicles through the purchasing of materials, manufacturing, use of products, recycling and final disposal, in order to actively reduce environmental impacts. Mazda has confirmed the benefits of its clean-energy vehicles and newly introduced vehicles with current model internal combustion engines.
In the LCA of the CX-5 conducted in FY March 2012, the CX-5 underwent a review by a thirdparty organization (Japan Environmental Management Association for Industry) and its conformity with the international standards (ISO 14040, ISO 14044) was certified.
The LCA is conducted in the same way for newly introduced vehicles, serving as objective and highly reliable proof that those new models are environmentally conscious throughout their entire lifecycles.
Mazda intends to steadily expand the implementation of LCA to new vehicles and confirm their environmental benefits.

Approaches and Targets in Each Area for 2020
To execute the Mazda Green Plan 2020, three committees set the following approaches and targets to promote each effort.
Products and technologies: Product Environment Committee
Mazda provides all customers who purchase Mazda vehicles with driving pleasure as well as outstanding environmental and safety performance.
Manufacturing, logistics, and office operations: Business Site Environment Committee
Mazda contributes toward realizing a low-carbon society through achieving even greater gains in operating efficiency by introducing low-CO2-emission production technologies and unwavering actions for constant improvement in the entire Mazda Group in Japan.
Social contributions (environmental area): Social Contribution Committee
Based on the three pillars of Mazda’s social contribution activities regarding the environment and safety performance, human resources development and community contributions, and a group-wide, global perspective, Mazda commits to disclosure and raising public awareness of environmental issues through its main business as an automobile maker. The Company also focuses on collaboration with regional communities, including volunteer activities.
