TAISEI Green Target 2050
Roadmap to a Sustainable, EnvironmentallyFriendly Society2026
Decarbonized Society / CN (Carbon Neutrality)
Scope1

Construction machinery,vehicles etc.

TAISEI is working to achieve and deepen “carbon neutral”,
a “circular economy” and “nature positive” to realize
the sustainable, environmentally friendly society envisioned by
the TAISEI Green Target 2050

2030

2050

Scope 1+2: Total emissions

Scope 1+2: Zero CO2 emissions▲ 4 2%(compared to 2022)
Scope 3: Total emissions▲ 2 5%(compared to 2022)

Scope 3: Zero CO2 emissions●Introduction of hybrid type
construction machinery, and GTL

New energy(hydrogen/ammonia)

throughout the supply chain●Introduction of innovative construction
machinery (electric, hydrogen etc.)●Introduction of new energy●New energy utilization●Contribute to the realizationof zero emissions throughincreased possession andsupply of RE

Scope2

Renewable energy
sources (RE)●Possession of renewable energy power sources to cover the Grouppower consumption needs

Scope3

Construction materials
that contribute todecarbonization●《T-eConcrete®,T-Green®
Multi Solar》Promotion ofdevelopment /dissemination●Increased dissemination andcommercial
application
ofconstruction materials that
contribute to decarbonization●Permeation throughout societyof construction materials that
contribute to decarbonization●Promotion of development
and dissemination of ZEB fornew building●100% ZEB for Taisei designbuildings●Tremendous advance inZEB performance●Development anddemonstration of T-ZCB®

Recycling-Oriented Society / CE (Circular Economy)

2030
Promotion of green procurement

Green procurement rate: 100%

Construction waste final disposal rate

Final disposal rate of construction
by-products: 0%:3.0% or less
3R+Renewable●Promotion of Reduce, Reuse, Recycle + Renewable

Construction wastes●Promotion of sorting andvolume reduction●Promotion of recycling

Soil generated byconstruction●Reorganization of management
system for soil generated byconstruction●Promotion of use of soil
generated by construction

Green procurement●Active use in design and construction projects / Encouragement of use insupply chain●Establishment of tabulation criteria and target setting●Significant increase in green procurement rate

Recycling of industrial byproducts●Development and dissemination of environmentally friendly concretethat utilize industrial by-products●Development and deployment of recycling technologies for concreterubble, plastic wastes, glass, sludge, etc.

Energy using biomass

BIM/CIM utilization

Soil and groundwater in-situ
purification

Regional cooperation●Technology development

2050●Realization of circular
economy● Implementation and deployment●Establishment of circular platform that associated with BIM/CIM●Promotion of visualization and circular materials in construction lifecycle●Advancement andprovision of technologies(compatibility with
substances that areexpected to be regulated,and reduced load)●Increased provision●Provision of technologies for revitalization and circulation of soil andgroundwater resources using DX●Demonstration and development of co-operative activities for recycling-oriented society, while utilizing localresources

2026
Nature Co-Existing Society / NP (Nature Positive)

Determining impact on biodiversity●Establishment andimprovement of evaluation
method / Implementation ofevaluation on major projects

Sustainable procurement●Procurement status survey

Implementation of proposals andconstruction work to contribute tonature positive●Promotion of greening andwaterfront creation●Development ofenvironmental restoration
technologies in oceans andother water areas●Development anddissemination of Green
infrastructure●Creation of nature in cities

2030

2050

・Minimize the adverse impacts from・Promotion of projects : 50 or more per year
our building construction business・Development of evaluation method :apply to 30% of design and construction projects ・Maximizing the positive impact ofimplementing business that coexist
・Respond to marine Issueswith nature
All of these contribute to being nature positive●Implementation of evaluation on
30% of design and construction
projects●Implementation of evaluationon all of design andconstruction projects●Transition to sustainable woodprocurement●Transition to sustainableprocurement for all
construction materials●Contribution to an OECM* toachieve the 30 by 30 Target● Promotion of solutions thatuse nature (NbS : Nature-basedSolutions)● Creation of workspaces inharmony with nature●Implementation ofinfrastructure projects thatregenerate nature●Creation of lifestyles that arein harmony with nature

All of these contribute topreserving and restoring
ecosystems
Regional cooperation●Demonstration and development of co-operative activities for nature co-existing society, while utilizing local
resources
