Climate Change Mitigation and Adaptation

The domestic Lintec Group is committed to carrying out various environmental activities to mitigate climate change and other environmental issues that impose risks on the continuity of its business.

Efforts in Manufacturing

Status of Compliance with Japan's Energy Conservation Law

Energy use by the entire Lintec Group in Japan exceeds 1,500 kl of crude oil equivalent each year. As a result, the Group was designated as a “specified business operator,” pursuant to the provisions of the Act on the Rational Use of Energy (“Energy Conservation Act”) in Japan, and is required to improve its energy use per production unit as well as its weighted electricity use per production unit (for reducing peak hour demand) by 1% per year. Additionally, many Lintec plants were designated as "specified business establishments" whose energy use is above 1,500 kl of crude oil equivalent. Since nine plants in Japan account for 95% of the Group's total energy consumption, it is important for each plant to take measures to reduce energy use. In fiscal 2021, the Lintec Group in Japan implemented a variety of energy-saving measures, such as effective operation of production facilities and boilers, air-conditioning control, and promoting the introduction of LED lighting. Due to the progress in energy saving, some business sites that have been designated as “specified business locations” may be reclassified to a different designation category or removed from the designation.

Energy Savings Promotion Committee

To comply with the Energy Conservation Act, the Lintec Group in Japan collects monthly data on energy consumption of individual sites under the direction of the Lintec Energy Savings Promotion Committee. In fiscal 2021, the Lintec Group in Japan implemented corporate-wide energy-saving measures aimed at improving its energy use per production unit. We request the respective plants to submit their plans and measures to achieve the target of 1% reduction per production unit, and compile data on the progress and results of these measures. Moreover, energy-saving practices that have proven effective are applied to other production sites.

Total Energy Use and CO2 Emissions

In fiscal 2021, total energy use (crude oil equivalent, covered by the Energy Conservation Act) for the Lintec Group in Japan increased by 5.2% from the previous year due to an increase in production volume. Energy use per unit of production was improved by 5.9% to 0.306 kl per ton. CO2 emissions were 159 thousand tons in fiscal 2021, down from 163 thousand tons in fiscal 2020. In fiscal 2022, we aim to reduce CO2 emissions and electricity consumption by 1.0% each on a per-unit-of-production basis compared to fiscal 2021 by facilitating the use of low-carbon electric power.

CO2 Emissions

  • ※1The amount of CO2 emissions is calculated by applying a CO2 emission coefficient to the amounts of electricity and fuel used.
  • ※2The CO2 emission coefficient for fiscal 1990 is the value specified in Article 3.1 of the Enforcement Order for the Act on Promotion of Global Warming Countermeasures in Japan as revised in December 2002. The CO2 emission coefficients after fiscal 2009 are the values specified in the same Order, as revised in March 2010. For the purchased electricity coefficients Lintec uses the emission coefficients provided by the power companies that supply electricity to the facilities concerned.
  • ※3The emissions shown above are CO2 emissions from fossil fuels.

Solar Power

Lintec has introduced photovoltaic power generation systems. In fiscal 2021, the system installed at the Doi Plant produced 1,025 MWh of electricity, and the system at the Agatsuma Plant generated 487 MWh of electricity. Additionally, systems for internal use were installed at the Ina Technology Center, the Kumagaya Plant, and Tokyo Lintec Kako, Inc. Multiplying the electricity generated at these plants by the coefficient announced in January 2022 results in a reduction effect of 1,206 t-CO2.

Efforts to Reduce CO2 Emissions

At the Kumagaya Plant, solar panels were installed in fiscal 2020 and put into operation at the end of that fiscal year in March 2021. Their installed capacity is equivalent to around 1.5% of the plant's power consumption. At the same time, part of the electricity generated is stored in batteries for networked computers in the office as a measure against momentary power loss. We will work on conversion to fuels with a lower emission factor and the introduction of more renewable energy as part of our continued efforts to reduce CO2 emissions.

Introduction of Cogeneration Systems

Lintec has introduced cogeneration systems that produce and supply electric power and heat from the heat source.
The Kumagaya Plant and Doi Plant have introduced gas engine cogeneration systems, which are systems that use LNG and other types of fuel and generate and supply electric power to operate various production facilities. These plants collect heat generated at the time of power generation in order to reclaim steam using an exhaust heat recovery boiler and run absorption chillers to produce cooling water.
Going forward, we are planning to introduce cogeneration systems to other plants.

Reducing Power Used for Lighting

The Lintec Group continuously encourages energy-saving activities. These include visualization of energy use, air-conditioning control, reduction of standby energy use during non-business hours. In addition, the introduction of LED lighting was promoted as planned, and the plans for fiscal 2021 were carried out in an ongoing manner.

Efforts to Prevent the Leakage of Fluorocarbons

Manufacturing sites are equipped with a number of industrial chillers and air conditioners that use fluorocarbon refrigerants. The Lintec Group, in compliance with the Fluorocarbon Emissions Control Act, creates a list of such equipment installed at its sites and conducts simple inspections and periodic inspections to prevent fluorocarbon leaks during use. When it comes time to dispose of the equipment, we entrust it to appropriate service providers to ensure the safe recovery of the compounds contained in it. There were no cases of violations. We will continue to adhere to the standards of judgment for managers set by the Act.
