Because the Cosmo Oil Group is involved in the production and sale of petroleum products, we believe that addressing global warming is a crucial issue. Efforts in this area are particularly important at our refineries, which account for more than 60% of total CO2 emissions produced by the Cosmo Oil Group. Accordingly, our refineries are undertaking energy conservation initiatives with an autonomous target of achieving a 15% reduction in unit energy consumption versus fiscal 1990 levels by fiscal 2010. We are also promoting energy conservation by executing efficient modes of delivery in logistics and introducing solar cell panels at service stations. Additionally, we are promoting efficient global warming countermeasures that utilize mechanisms under the Kyoto Protocol. To augment these initiatives implemented in our business activities, significant efforts are also dedicated to environmental activities that extend beyond our corporate boundaries as part of our total commitment to contribute to the prevention of global warming.

Clean Development Mechanism (CDM): A Kyoto mechanism that allows industrialized countries to generate emission credits through investment in emission reduction projects in developing countries 3. Joint Implementation (JI): A Kyoto mechanism that allows developed countries to invest in other developed countries to earn carbon allowances that can be used to meet their emission reduction commitments
* Unit energy consumption is expressed as the total energy consumption divided by crude oil equivalent throughput taking into account the complexity of refining techniques. The unit is kl-crude oil/thousand kl. Note that different types of energy consumed are converted into a common denominator of kl-crude oil equivalent.

Energy Consumption at Four Refineries

CO2 Emissions at Four Refineries
The Cosmo Oil Group has long pursued energy conservation voluntarily by achieving greater efficiency in its logistics system. In fiscal 2006, amendments to the Energy Conservation Law were enacted to clearly define cargo shippers' responsibility.
Adhering to the revised law, Cosmo Oil firmly ascertained the volume of its domestic shipping (ton-kilometers) and the volume of CO2 emissions. During fiscal 2006, we were engaged in the transport of 6,395,890 ton-kilometers of freight, and CO2 emissions amounted to 160,535 tons.
We will continue to pursue energy conservation based on safe and reliable transportation.
Land Transportation: Tanker Trucks
Utilizing large trucks and maintaining a high stowage rate resulted in a 30% increase in transportation volume per vehicle versus fiscal 1990 levels. To further conserve energy, our efforts to promote efficiency will focus on systematic delivery and independent unloading.
Domestic Marine Transportation: Coastal Tankers
Coastal tankers used to deliver our main and semi-processed products between sites are affected by the operational status of refineries, weather conditions, and other factors. To meet our dual objectives of preventing accidents and making environmental considerations, we work to reduce energy consumption by using larger tankers and maintaining a high stowage rate.

Ballast Water
When sailing without a load from Japan and other oil-consuming countries to oil-producing countries, crude oil tankers must hold sea water inside as ballast to maintain ship stability. This sea water is then discharged before crude oil is loaded. To prevent the disruption of the coastal ecosystems and pollution of oil-producing countries, this ballast water is discharged off the coast in accordance with local regulations and requirements.
Double-Hull Structure
The Cosmo Oil Group employs 10 Very Large Crude Carriers (VLCCs) with a double-hull structure as protection against accidents. These tankers, under a long-term charter, are equipped with both inner and outer hulls. In the event the outer hull is breached, this double-hull structure diminishes the risk of damage to the inner crude oil tank to prevent oil leaks.

Introducing Hydrocarbon Vapor Recovery Units
To prevent hydrocarbon vapor from being diffused when being unloaded from tanker trucks, we promote the installation of hydrocarbon vapor recovery units.
