Long-Term Plan

Long-Term Targets

Hitachi Construction Machinery Group has set long-term targets and is working to reduce the environmental burden of its product life cycle with the aim of realizing a “Low-carbon Society” and “Resource Efficient Society.”

Reducing CO2 Emissions

Hitachi Construction Machinery Group aims to reduce CO₂ emissions throughout the entire value chain. We promote activities aimed at decarbonization by setting two goals: reducing greenhouse gas emissions from business activities and reducing greenhouse gas emissions associated with the use of products and services.

Hitachi Construction Machinery Group’s Targets for Greenhouse Gas Emission Reduction

Indicators Targets for absolute emissions reduction FY2020 Results
Reduction in greenhouse gas emissions Scope 1, 2 By FY 2030 (compared to FY2010) 45% 37.2%
Scope 3 33% 16.5%

Scope1:Direct emissions of greenhouse gases from emission sources owned or managed by companies or households
Scope2:Indirect emissions of greenhouse gases associated with the use of electricity, steam, and heat
Scope3:Other indirect emissions excluding scope 2

In May 2019, the long-term targets for greenhouse gas emission reduction established by Hitachi Construction Machinery were approved as targets based on science by the Science Based Targets initiative (SBTi)*1.
This target meets the requisites of the temperature increase of less than 2℃ scenario (IPCC:RCP2.6) .
Going forward, we aim for higher goals and will accelerate energy saving and low carbonization to achieve carbon neutrality.

Resource Circulation

In order to contribute to the effective use of  resources, Hitachi Construction Machinery Group set the targets below and is working on water use (including fresh water) reduction, water recycling and waste reduction from our business activities.

FY2020 Results FY 2022 Targets FY 2022 Targets
Water Consumption Reduction (per unit of production) -36.8% (Compared to FY2010) -28% (Compared to FY2010) Advanced water recycling usage, Minimization of regional impact
Recycling Rate (in Japan) 83.3% (Compared to FY2010) 99.5% (Compared to FY2010) Aim for 99.5% or higher

Environmental Action Plan

To promote achieving the Environmental Vision and the long-term plan, Hitachi Construction Machinery has determined the Environmental Action Plan, set the specific activity items and aims, and is taking initiatives accordingly.

This Environmental Action Plan formulates standardized indexes (quantitative targets and non-quantitative targets) across the group that are to be implemented by manufacturing group companies and sales group companies in Japan and overseas. Each company bases their annual environmental planning on our Group Environmental Action Plan, and carry out their environmental activities accordingly. In October, the mid-point of the plan, we check the progress state of each company and make sure things are going accordingly.
The following shows the medium-term targets and actions regarding the Environmental Action Plan.

As at the end of September, 2021
