CSR Charter ⅡHarmonizing with the Environment and Contributing to Realizing a Sustainable Society
Environmental Action Targets
Principle and Outline
The Daigas Group has set out medium-term environmental targets to reduce environmental impact by the Group as a whole, particularly in its city gas business, and is monitoring the progress being made toward achievement of these targets.
In pursuit of the environmental action targets, we will be seeking to make environmental management more efficient, reduce CO2 emissions, curb waste generation and promote recycling, and reduce the volume of excavated soil for final disposal.
Environmental Action Targets and FY2018 Results
Steady progress was made toward achieving the environmental action targets for FY2021, as evidenced by the improvement of most indicators of environmental management efficiency, an integrated yardstick used to assess our environmental conservation activities. Behind the improvement were the start of full-scale operation of the cryogenic power generation facilities for LNG terminals, progress in the reuse of excavated soil, and enhanced energy-saving activities, including the introduction of LED lighting in FY2018.
Environmental Action Targets (for FY2021)
|Field||Indicators||Targets for FY2021||FY2017 Results|
|Integrated indicator||Environmental Management Efficiency||Environmental impact of gas business per gas produced (Monetary value (yen) of GHG, excavated soil, waste, NOx, COD, chemical substances, water consumption / gas produced (1,000 m³ ) )||14.2 or less
(22% decrease compared to FY2009)
|Low-carbon society||Reducing CO2 emissions from our business activities||City gas
|LNG terminals (CO2 emissions per 1 million m³ of gas produced) (t-CO2 / 1 million m³ )||11.7 or less
(12% decrease compared to FY2009)
|Office buildings (CO2 emissions per 1000 m² floor space)||56.5 or less (27% decrease compared to FY2009)||54.7|
|Group companies' businesses*2||Electricity business (including renewable energy sources) (CO2 emissions per electricity generated)||15% decrease compared to FY2009||32% decrease|
|Other businesses (CO2 emissions per sales) (t-CO2 / 10 million yen)||8.2 or less (12% decrease compared to FY2009)||9.2|
|Reducing CO2 emissions on customer sites and throughout the value chain||Customers||Centered on natural gas, Osaka Gas aims to reduce greenhouse gas emissions by diffusing energy-efficient value-added products.
|Transportation / logistics||
|CO2 emissions reduction for entire Group (t-CO2) (including contribution to reductions at customer sites and overseas)||7 million tons||0.61 million tons|
|Resource recycling||Promoting the 3Rs in our business||Gas business||Industrial waste from LNG terminals (final disposal rate)||1% or less*1||0.1%|
|Industrial waste from facilities other than LNG terminals (final disposal rate)||1% or less||0.8%|
|General waste (final disposal rate)||3% or less||2.3%|
|Excavated soil (final disposal rate)||1% or less||0.4%|
|Polyethylene (PE) pipes (recycling rate)||100%||100%|
|Gas meters (reuse rates)||98% or more||99.5%|
|Group companies (core affiliates*2)||Industrial waste / general waste (final disposal rate)||4% or less||3.3%|
|Efforts throughout the value chain||
|Technology development||Promotion of technological development to help create a low-carbon society and further solidify the Company's already solid business foundation
|Green procurement / purchasing||
- *1 Industrial waste from LNG terminals (final disposal rate)
- Industrial waste covered for the rate calculation excludes the disposal of PCB, a chemical substance whose disposal by 2027 is mandatory.
- Of 138 Osaka Gas consolidated subsidiaries, 57 companies are subject to the calculation of greenhouse gas emissions. Those housed in office buildings as tenants and whose environmental data are difficult to grasp and whose environmental effects are minimal are not subject to such calculation. Also excluded from the calculation are overseas companies whose environmental impacts are minimal. The number of companies covered by the calculation changes every year, depending on corporate integration and other streamlining actions taken during each year.
- Osaka Gas is the representative of the Association.
Long-Term Vision toward FY2031
We will continuously strive to reduce the environmental impacts of our business activities, and from our products and services, in cooperation with our customers in line with the Daigas Group Environmental Activities Policy, adopted in 2006. We will also step up environmental improvement activities both in Japan and overseas, including regional areas. By taking all these actions, we are committed to helping create a sustainable society.
Specifically, we will encourage our customers to introduce energy-efficient appliances deemed effective in saving energy and reducing CO2 emissions, such as fuel cells and gas cogeneration systems. We will also promote a switch to environment-friendly natural gas, the active use of energy-saving technologies, and the development and introduction of the most advanced fossil-based power stations and renewable energy sources. By implementing all these measures, we aim to reduce CO2 emissions by a cumulative 70 million tons between FY2018 and FY2031. The reduction target covers emissions reduction by customers and through our overseas operations. We will continue to promote environmental management by taking into consideration resource recycling, biodiversity and the safety of chemical substances.
Participation in the KEIDANREN's Commitment to a Low Carbon Society
The Japan Business Federation (Keidanren) recognizes global warming as a global-scale issue to be addressed on a long-term basis. Based on this recognition, Keidanren has set out a common vision for Japan's industry—using its technological expertise to play a pivotal role in global efforts to halve greenhouse gas emissions in the world by 2050. This vision was transformed into a Keidanren action plan to create a low-carbon society, drawn up in 2013 and revised in 2017. The action plan spells out what each participating industry should do in Japan through the maximum use of “best available technologies” (BAT) to reduce as much as possible CO2 emissions from business activities and people's life-related activities. The action plan also calls for each industry to provide strong support to overseas efforts to stem global warming. Also set in the action plan are goals and activities aimed at strategically developing innovative technologies that could become a breakthrough for the 2050 CO2 reduction goal.
The Japan Gas Association and the Electric Power Council for a Low Carbon Society (ELCS), both participating in the action plan, have formulated their respective industry plans for realizing a low-carbon society. Osaka Gas, a member of both the association and the ELCS, has joined the industry plans and is working out measures to combat global warming (climate change).
