DAIICHI SANKYO to Implement Carbon Offset Program

Tokyo, July 7, 2008 - DAIICHI SANKYO COMPANY, LIMITED has announced that to help curb global warming, it will purchase carbon offset^*1 credits for the emissions from its fleet of sales vehicles.

In order to decrease CO2 emissions, DAIICHI SANKYO already incorporates eco-driving measures and has converted its sales fleet to low emission, fuel-efficient vehicles, including hybrids. It also utilizes public transportation for its sales efforts. Now, as an additional measure to help fight global warming, it has obtained carbon offset credits sanctioned under the Clean Development Mechanism (CDM)^*2 to offset its carbon footprint which is unavoidable due to business activities (9,000 tons annually).

The emission offset credits are purchased through the Korean Ulsan Project^*3, recognized by the UN CDM Executive Board. The acquisition of credits and transfer of funds to the Japanese government-managed account was carried out by Tokyo Leasing Co., Ltd. and Tokyo Auto Leasing Co., Ltd.

DAIICHI SANKYO continues to make efforts in all of its areas of business to contribute to the curbing of global warming as one of its CSR initiatives to help protect the environment.

*1 Carbon offset
In addition to proactive efforts to reduce carbon emissions, unavoidable emissions are neutralized through the purchase of carbon offset credits from entities that have successfully reduced greenhouse emissions.

*2 Clean Development Mechanism (CDM)
The Clean Development Mechanism, defined under the Kyoto Protocol, is a scheme which allows industrialized countries to earn emissions credits from their investments in emission-reducing projects in developing countries towards meeting national targets.
The certified emission reduction credits are reported to the Japanese government through Tokyo Leasing to help the Japanese government meet its Kyoto Protocol targets.

*3 Korean Ulsan Project
The Ulsan Project is a greenhouse gas reduction project developed by Ulsan Chemical Co., Ltd. of South Korea.
