Initiatives to prevent
CO2 emission trends
In fiscal 2019, the Group's total CO2 emissions were up 8% from fiscal 2015. This does not include the emissions attributed to one site outside Japan that joined the Group in fiscal 2019, as it was not included in the total for the base year. Breaking this total down, energy-derived CO2 emissions in Japan were down thanks to group-wide energy-saving activities and the closure of a site. Even though emissions by sites outside Japan remained about the same, the worldwide total dropped by 9%. On the other hand, CO2 emissions generated through industrial waste incineration were up 19% from fiscal 2015. The Asahi Holdings Group is helping to extend the lifespan of final disposal sites by incinerating waste plastic and drastically reducing its volume.
The main reason for the emissions increase was a jump in the amount of waste plastic incinerated after updating incinerators.
As one of its priority SDG-related goals, the Group is working toward a 26% reduction in CO2 emissions by fiscal 2030, compared to fiscal 2015. The Group's energy-derived CO2 emissions in Japan mainly stem from power consumption in offices, power and fuel consumption in factories, and fuel consumption by sales and other vehicles. Overseas, these emissions originate from power and fuel consumption in factories and offices. Non-energy-derived CO2 emissions arise from the incineration of industrial waste.
We focus on energy-derived CO2 emissions in particular, and aim to achieve our target not only through in-house efforts, but also by utilizing resources outside the company. These include generating power from waste, reducing energy use for air conditioning, lighting and vehicles, and changing electric power providers.
＜Scope of data＞
Headquarters, sites, sales offices and plants in Japan, as well as Group companies*, and overseas subsidiaries* (calculation period: April to March)
* The data pertains to consolidated subsidiaries as of March 31, 2020. Data for subsidiaries that were previously non-consolidated has been added retroactively, going back to the fiscal year when the subsidiary became consolidated.
Energy-derived emissions: Calculated based on the amounts of electricity and fuel consumed at each site (emissions in Japan calculated based on the Act on Promotion of Global Warming Countermeasures, and the Act on the Rational Use of Energy) Non-energy-derived emissions: Calculated based on the amount of industrial waste incineration
Generating power from waste
Waste-to-energy is a power generation method that uses the heat generated from waste incineration. It produces high temperatures and high-pressure steam that turns a turbine and generates power.
By taking advantage of the energy released during waste incineration to produce electricity, the Group can reduce the amount of fuel used, thereby reducing CO2 emissions accordingly.
The Group is constructing a waste-to-energy power plant in the city of Kitakyushu. By achieving advanced and highly efficient heat recovery, we are helping to prevent global warming and build a low-carbon society.
