Strategy｜ We identify “risks and opportunities” assuming the year 2030 and evaluate
their impacts on the Group’s business
Risks
To diminish our reputation among ourstakeholders, decline opportunities forsecuring orders, etc., in the event ofthe Group’s initiatives to be evaluatedas inadequate

Decarbonizedsociety

RecyclingOriented Society

Nature CoExisting SocietyTo decline in productivity and decreased
workforce due to a worsened working
environment caused by rising temperaturein summer, rising labor costs, rising pricesof construction materials due todisruptions in the supply chain caused byincreasing severity and frequency ofnatural disasters, etc.

Opportunities
To enhance corporate value andreputation among stakeholders
through various initiatives toward
Decarbonized Society, RecyclingOriented Society, and Nature CoExisting Society

Measures
Measures to address risks
and opportunities

Increased demand for ZEB andrenewable energy-related constructionworks, as well as strengthening facilities
and infrastructure in order to adapt toclimate change, etc.

To develop and promote labor-saving
construction technologies, as well as todevelop and promote realization in oursociety: low-carbon and decarbonizedbuilding materials such as T-eConcrete
and T-Near Zero Steel; ZEBs; and Zero
Carbon Buildings (T-ZCBs); etc.

Rising prices of construction materials
due to resource shortages, increased
construction costs due to increased waste
disposal costs, etc.

Increased use of recycled resources that
contribute to the realization of a circular
economy, and increased opportunities forsecuring orders for environmental
restoration projects, including soil
decontamination

To develop and promote materials andconstruction methods that take into
account of resource-recycling, such as TeConcrete and T-Near Zero Steel,sophistication of low-impact soil andgroundwater decontamination
technologies for substances that areexpected to be regulated in the future,such as PFAS※

Rising prices of construction materials
due to resource shortages, increased
construction costs due to the higher levy
for restoration and conservation of naturalenvironment, etc.

Increased opportunities for securing
orders related to the conservation andcreation of a rich natural environment that
contribute to the realization of a nature
positive society and development ofgreen infrastructure

To develop nature-positive evaluation
methods, as well as to develop andpromote social implementation ofenvironmental forecasting technologies,
biodiversity planning technologies, andgreen space developing technologies
such as T-GI rain garden* Per- and PolyFluoroAlkyl Substances: A general term for perfluoroalkyl compounds and polyfluoroalkyl compounds
