- How much CO2 does the Hitachi Group emit through its business activities?
- Currently 2.8 million tons from domestic operations and 1.43 million tons from overseas operations (as of FY2007).
There are 249 companies under the Hitachi Group that are currently engaged in manufacturing activities. CO2 emissions from such group companies operating in domestic and overseas are 2.8 million tons and 1.43 million tons respectively as of now (FY2007).
In FY2005, there were emissions of 2.8 million tons from domestic operations and 1.63 million tons from overseas operations.
- On what basis did you set the CO2 emission reduction target at 100 million tons?
- To set the target, we calculated the contributions to CO2 reductions from products at both energy supply points and energy consumption points, and added them up.
In other words, the target set is the sum total of expected reductions from products related to energy supply, such as high-efficiency thermal energy, nuclear power and renewable energy, and expected reductions from products related to energy consumption in areas such as business, consumer and transportation.
- * The CO2 emission reduction of 100 million tons is based on the relative comparison with emissions from products manufactured according to the technological standards of 2005.
- * 'Products' here include services and solutions.
- * Our intention is to contribute to reductions of 100 million tons of CO2 across the entire global market, not just in the Japanese market.
- How is Hitachi going to contribute to CO2 emission reductions?
- By reducing the environmental impacts of our products and promoting a wider use of such products.
While striving to reduce the environmental impact of our products and achieve higher energy efficiency through technological development and technological innovation, we are also promoting the use of products with low environmental impact throughout the global market, thereby contributing to CO2 emission reductions around the globe.

- How large is a volume of 100 million tons?
- This is the volume that can be absorbed by an artificial cedar forest about the size of one-third of Japan' s territory.
For example, to absorb 100 million tons of CO2, it would require an artificial cedar forest of about 130,000 square kilometers. This is equivalent to an area of 360 square kilometers, or about one-third of Japan' s territory, or more specifically, the total area of Hokkaido and Kyushu.
- How much CO2 is emitted in the course of generating 1kWh of electricity?
- The amount of CO2 emissions varies significantly depending on the energy source, whether it is thermal power, nuclear power and wind power.
It is also heavily influenced by various conditions such as fuel type, characteristics of power plants and plant operation methodologies. For example, the following shows the emissions from each type of power plant according to the Central Research Institute of Electric Power Industry (CRIEPI). These represent the total amount of CO2 emitted throughout the entire lifecycle of energy, ranging from mining and transportation of fuels to construction, operation and maintenance of power plant facilities.
- Coal-fired thermal power plant: 975g- CO2/kWh (sending end)
- LNG thermal power plant: 608g- CO2/kWh (sending end)
- Nuclear power plant: 22g- CO2/kWh (sending end)
