I.Toward Achieving the Environmental Vision 2050: Efforts made in various business domains

Social Infrastructure Business

Contributing to the Prevention of Global Warming and Better Society with Innovative Environmental Technologies

Toward Realizing the Environmental Vision 2050
Contributing toward Control of Global CO2 Emissions

Through our social infrastructure business, Toshiba Group can contribute to controlling CO2 emissions in power generation systems. By expanding nuclear power generation system (which does not generate CO2), improving the efficiency of thermal power generation, promoting businesses such as carbon capture and storage globally, Toshiba Group aims to contribute to reduce CO2 emissions by 82 million tons by 2025, which is equivalent to the annual emissions of Tokyo City.
Our energy-saving efforts extend to the social system business such as traffic control system, development of elevator, medical equipment, etc. through the use of stateof-the-art environmental technologies. Furthermore, through the promotion of CDM* business, we are contributing toward the reduction of global CO2 emissions.

*CDM: Clean Development Mechanism

Case 1
Safe and economically efficient nuclear power generation

In FY2008, we received orders for 8 nuclear plants*1 in the US. In France, for the first time, we have received orders for repair work of turbo generator of nuclear plants. We have also set up Japan's largest fast breeder reactor nuclear facility within Toshiba's Yokohama Complex and are developing fast breeder reactors with higher uranium-saving rate.
On the other hand, in order to reduce CO2 emissions for thermal power generation systems, we are promoting the development of the A-USC*2 thermal power generation system in which the steam temperature is increased from a class of 600°C in the conventional system to 700°C, while simultaneously building a CCS*3 pilot plant at a commercial scale. As a result of the combined use of A-USC and CCS, an approximately 90% CO2 reduction from the current levels is possible.

Two ABWRs (1.4 million kW class nuclear reactors) and six AP1000s (1.1 million kW class nuclear reactors)
2
Advanced-Ultra-Supercritical
3
Carbon Capture and Storage

Reducing CO2 emissions of Thermal Power Generation

Approx. 90% reduction possible

Note:
Currently, only the USC (Ultra-Supercritical) is put to practical use. Drastic CO2 emissions reductions possible with a combination of A (Advanced)-USC and CCS.

Case 2
Expanding Environmentally Conscious Businesses to Sustain Global Society

Our other efforts also include mass production of new rechargeable batteries, namely, SCiB™ and collaboration with a European automobile manufacturer for their application. In December 2008, to meet the growing global demand for high-efficiency motors which support energy saving of various electrical products, we established a manufacturing base in Vietnam. We also set up a CDM project in the country.
In order to promote CDM business, in January 2009 Toshiba established a new company in Vietnam with NGUYEN VU Co., Ltd. The project will use Toshiba's high concentration organic wastewater treatment technology to recover biogas* from wastewater discharged by starch factories in order to reduce the atmospheric greenhouse gas emissions. The new company aims to construct methane gas recovery plants in multiple starch factories to reduce GHG emissions in terms of CO2 by 70 thousand tons in FY2010. Similar type of plants will be installed in alcohol and food processing factories to reduce greenhouse gas emissions by 500 thousand tons in terms of annual CO2 volume.

*Biogas:
A combustible gas whose dominant component is methane gas recovered from organic wastewater by methane fermentation process
