CSR Report 2018 Terminology

B

Back-casting

Back-casting is a thinking method in which action is taken based on a strategy deemed necessary with the aim of attaining a desirable future goal. The method is designed to provide solutions to problems that are impossible to be solved under traditional approaches or thinking by envisaging an ideal future and working backwards to formulate measures that can make up for the gap with the present situation.

Ballast water

Because a ship is more prone to capsize when it carries less cargo, water is pumped into an unloaded cargo ship to provide stability. This water, serving as a counterweight, is called ballast. Water used as ballast is called ballast water, which is usually taken from coastal port areas. It is concerned that the contained organisms in the ballast water could be non-native species and thus may harm the ecological system of the seawater in the next port of call area when it is discharged.

Biogas

Biogas is a combustible gas derived by methane fermentation of anaerobic microorganisms in organic waste such as raw garbage, livestock manure and sewage sludge. The principal components of biogas are methane and carbon dioxide. It is an unused renewable energy source, of which efficient use is expected to contribute to the mitigation of global warming.

Boiler operating efficiency

Overall boiler efficiency after long-term use, which takes into account load changes when the boiler is switched on or off.

Business continuity plan (BCP)

BCP is a plan or management strategy aimed at preventing business interruption in the event of a disaster or enabling the recovery of important corporate functions within a targeted time period even if business comes to a halt.

C

Carbon offset

Carbon offset is the concept of offsetting CO2 or other greenhouse gas (GHG) emissions from homes or businesses by investing in projects such as afforestation, forest conservation and clean energy businesses that reduce greenhouse gases. In carbon offset products, an amount is added to the price and this added amount is donated to greenhouse gas reduction projects. By purchasing such products, consumers can indirectly contribute to greenhouse gas reduction.

Carbon pricing

Carbon pricing is a method of charging parties who emit greenhouse gas (GHG) including CO2. The pricing is designed to reduce GHG emissions by having business corporations and households shoulder the cost of emissions the public pays according to the amount of their emissions. Carbon pricing takes the form either of a carbon tax, levied on emitters in proportion to the amount of their CO2 emissions deriving mainly from the use of fossil-based fuels, and emissions trading, a method to control CO2 emissions through the trading of surplus or deficit emissions permits between countries or business corporations.

Clean Development Mechanism (CDM)

An arrangement under the Kyoto Protocol in which developed countries support developing countries with technologies or investment that contribute to greenhouse gas reduction, and a portion of the reduction is counted as reduction by the developed countries. Defined under Article 12 of the Kyoto Protocol.

Cleaning up the site

A method that conducts on-site purification without excavating contaminated soil.

CO2 Emissions from Energy Consumption

Condensate

A type of ultra-light crude oil that exhibits similar characteristics to naphtha and gasoline.

Cryogenic power generation

Osaka Gas imports LNG, that is natural gas liquefied in producing countries. This LNG is a liquid with a temperature of minus 160 degrees Celsius, and when it vaporizes back into natural gas it absorbs heat from the surroundings giving it cooling properties (cryogenic energy). This energy is equivalent to about 240 kWh of electricity per ton of LNG. Recovering this as kinetic energy and using it for power generation is referred to as cryogenic power generation.

D

Demand response

Demand response represents efforts by the demand side or electricity users to strike a supply-demand balance of electricity by saving their power consumption.

Digester gas

Digester gas is made by anaerobic fermentation in sewage sludge where no oxygen exists. It is mainly composed of methane and CO2.

The system and procedures for this are collectively called EMS.

Ethnicity

“Ethnicity” is a term that indicates an individual's particular group based on language, customs, region, religion, family background or physical characteristics. More narrowly, ethnicity can be translated as “being ethnic.” “Ethnicity” is used more broadly than "being ethnic" since the former is used when an individual belongs to a particular group according to more diverse and wider elements concerning his or her belonging.

Excavated soil

The earth, sand, and asphalt that are dug up when gas pipes are constructed under roads or when gas pipes are moved.

F

FIT electricity

FIT stands for feed-in-tariff. FIT is a mechanism designed to spread the use of renewable energy sources such as solar power and wind power by obliging utility companies to purchase such energy sources from renewable energy producers at fixed rates set by the state for a certain period. FIT electricity is electricity generated using renewable energy sources purchased under this mechanism.

G

Gas cogeneration system

An energy-efficient system that runs on city gas, generating the power and heat where they are used such as homes and businesses, and using the waste heat from the system to heat or cool the air, or to heat water.

There are three types of gas pipes depending on the pressure of the gas running through them: high-, medium-, and low-pressure gas pipes. The gas that leaves LNG terminals flow through a high-pressure pipeline. A pressure regulator adjusts the pressure to medium- and low-pressure levels before the gas is delivered to our customers through a low-pressure pipeline.

Gas turbine combined cycle power generation method

A high-efficiency power generation method in which gas turbines and steam turbines are combined. City gas, mixed with compressed air, is combusted in the burner, and the pressure generated by the combustion drives a turbine to generate electricity. Next, the heat of the exhaust gas from the turbine is used to generate high-pressure steam in a waste-heat collecting boiler, and this steam drives a steam turbine to generate electricity. This use of heat from the exhaust gas gives the gas turbine combined cycle method a high power generating efficiency.

GHG (Greenhouse Gas) Protocol

GHG protocol is guidelines established by the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI) that set out the philosophy and rules for calculating greenhouse gas emission and reduction amounts.

Greenhouse gas (GHG)

GHG refers to gases in the atmosphere that contribute to the greenhouse effect by absorbing infrared radiation produced by solar warming of the earth's surface. The Kyoto Protocol defines seven greenhouse gases whose emissions should be reduced; which are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulphur hexafluoride, and nitrogen trifluoride.

GRI Standards

GRI Standards are sustainability reporting standards developed by Global Reporting Initiative (GRI), an international nongovernmental organization (NGO), with the aim of attaining sustainable social development through promoting the compilation of policy measures and policy plans by business corporations, and stepped up efforts to take specific actions to implement the measures and plans. Under the GRI Standards, business corporations are required to identify significant impacts that their activities are expected to have on the economy, environment and society, and report such impacts to the GRI as materiality items. The initial edition of the GRI Guidelines was issued in 2000. The guidelines were revised several times before shifting to the GRI Standards in 2016. Companies are required to disclose “general disclosure items” and “management approach” under universal standards, and items identified as “materiality,” chosen from “economy,” “environment” and “society” under item-by-item standards. GRI Standards, officially called GRI Sustainability Reporting Standards, were issued on July 1, 2018.

Replacing pipes without excavation

This is a method of burying polyethylene (PE) pipes in which only each end of the construction stretch is excavated. Not only does this these methods result in less excavated soil, it they also reduces the impediment of traffic around the construction site.

Resilience/Resilient

“Resilience/Resilient” is a term that means easily being able to return to an original shape after being bent with great force. The term has recently been applied to the ability of the Japanese government to respond to the risks of major natural disasters, such as an expected huge earthquake in central Tokyo and an expected powerful earthquake in the Nankai Trough that runs off central and western Japan, emphasized in the country’s policy of national resilience. It is considered imperative for Japan to establish a strong and flexible social infrastructure able to minimize possible damage from natural disasters and enable the speedy recovery and rehabilitation from such damage.

Reverse power output flow

A situation in which redundant power output from distributed electric sources, such as solar power and cogeneration systems, are flowed back into commercial power distribution networks.

S
