Hitachi's Environmental Vision

The Three Pillars of Hitachi's Environmental Vision
[image]Prevention of Global Warming Reduce CO2 emissions in energy production Enhance energy efficiency of our products Conservation of Resources Collect products for reuse or recycling Preservation of the Ecosystem Reduce negative effect on air, water, and soil

The quest for a comfortable existence has led humankind to create a highly convenient society. Today's society, however, requires a vast amount of energy, and is causing problems, such as global warming, resource depletion, and environmental damage. We should challenge these common issues if we are to maintain a comfortable existence into the future.
We are committed to the prevention of global warming, the conservation of resources, and the preservation of the ecosystem as the three pillars of our vision. Our goal is to achieve a more sustainable society by promoting global production that reduces the environmental burden of a product throughout its lifecycle. We are working toward this goal by setting progressive targets for fiscal 2010, 2015, and 2025.

Global Warming Prevention toward 2025

We are setting specific goals intended to prevent global warming, which we view as a particularly urgent mission in realizing a sustainable society.

Fiscal 2010 Goal

[image]12 percent reduction in Hitachi Group CO2 emissions (from FY 1990 for Japan domestically), 5 percent reduction in CO2 emissions per unit of production (from FY 2003 for outside Japan)

To meet Japan's Kyoto Protocol commitment of a 6-percent reduction in greenhouse gases, the Japanese government has created the Kyoto Protocol Target Achievement Plan. In fiscal 2008, we raised our fiscal 2010 CO2 emission reduction target from 7 to 12 percent. This is now in line with the industry target value laid out in the Achievement Plan that was revised in March 2008. For operations outside Japan, we are striving to achieve an annual reduction of 1 percent in CO2 emissions per unit of production.

Fiscal 2015 Goal: Medium-Term Environmental Vision 2015

We are working to become emission neutral by fiscal 2015 in the pursuit of monozukuri that reduces the environmental burden of products throughout their lifecycle.

The Emission Neutral Concept

The Emission Neutral Concept

Emission neutral means reducing CO2 emissions from material production, manufacturing and distribution (the direct burden) and also reducing CO2 emissions by making energy- and resource-saving products (the social burden) to make the two environmental burdens equal.

Fiscal 2025 Goal: Long-Term Environmental Vision 2025

[image]To help reduce annual CO2 emissions by 100 M tonnes through Hitachi products by 2025

In 2007, we set a goal to reduce annual CO2 emissions by 100 million tonnes by 2025 through Hitachi products and services. Seventy percent, or 70 million of that 100 million tonnes, comes from power generation and other aspects of energy supply, while 30 percent, or 30 million tonnes, is associated with energy consumption, including industry, transportation, commercial and residential use.
For power generation and energy supply, we will provide products that reduce CO2 emissions by expanding the provision of nuclear power and renewable energy technologies, as well as further improving the efficiency of thermal power generation. For energy consumption, we are committed to pursuing high energy efficiency in industry, transportation and daily living, such as developing hybrid drive systems that use lithiumion batteries and creating power-saving data centers that integrate ICT (information and communication technology) with air conditioning technology.

Breakdown of 2025 CO2 Emission Reduction

Specific Steps to Help Reduce CO2 Emissions by 100 Million Tonnes

  • Make all of our products Eco-Products.
  • Pursue environmental efficiency of products through technology.
  • Promote green technology, environmental business investment and collaborative projects in global markets.

Product Development for a Sustainable Society

To reduce the environmental burden of CO2, we are building up the environmental efficiency of all products.
First, we intend to make all Hitachi Group products Eco- Products*1 by fiscal 2025. To achieve major improvements in environmental efficiency, we have also developed the Super Eco-Product classification. These are Eco-Products that have either an efficiency of global warming prevention*2 or a resource efficiency*3 at least 10 times greater than standard products (fiscal 2000 products), or when these products are industry leaders based on their achievement ratios of energy conservation standards*4 or other similar indicators, or are highly regarded outside the Hitachi Group. The intention is to boost the percentage of Super Eco-Products to Eco-Products to more than 30 percent by fiscal 2010. We have identified the environment and energy as priority areas for channelling Group resources.
We look forward to using our technology to meet the challenge of environmental protection, another step toward achieving a sustainable global environment.

Hitachi's Eco-Product System

Products that meet certain standards under the Assessment for DfE (Design for Environment) system, which uses criteria such as material reduction and longevity to provide a quantitative assessment of environmental burden.
Efficiency of global warming prevention
When evaluating a product's value for function and life span, the ratio of that product's value to the quantity of greenhouse gases generated during its lifecycle.
Resource efficiency
When evaluating a product's value for function and life span, the ratio of that product's value to the amount of resources used during the product's lifecycle.
Achievement ratios of energy conservation standards
Standard target values for energy efficiency have been established for home appliances and other products on the basis of the Law Regarding the Rationalization of Energy Use. The achievement ratio indicates the degree to which these standard target values have been met. The target values were determined with reference to the most energy-efficient products available in the market.
