Embodied carbon in office interiors

• Fit-outs generate more embodied carbon than base building construction over a building's lifespan, making sustainable fit-out materials a critical decarbonization lever.
• Material data is now business-critical, driven by tightening standards, investor scrutiny, and scope 3 commitments across APAC.
• Leading owners and occupiers leverage circular strategies to achieve carbon reductions and cost savings.
• Systemic enablers are required to drive change at scale: reformed lease structures, digital infrastructure, and cross-industry partnerships.

The carbon equation in corporate real estate (CRE) and the built environment is shifting. While current decarbonization efforts are focused on building operations, operational carbon emissions are projected to plateau as buildings become more energy efficient and adopt clean energy. The share of embodied carbon, which refers to emissions from building materials and products throughout their lifecycle, is projected to grow to half of building emissions by 2050, making it a decarbonization priority.

This challenge is particularly acute in interior fit outs. The material and design choices in fitting out or renovating an office space impact its carbon footprint; high-specification fit-outs can generate up to five times the carbon emissions of low-carbon, optimized fit-outs. Furthermore, reinstatement commercial lease clauses are prevalent in Asia Pacific (APAC), requiring tenants to remove furnishings and restore office spaces to their original state. Recurring fit-outs, renovations and strip-outs accumulate emissions that can exceed the base building’s carbon footprint by up to 4 times over a building’s lifespan.

JLL Research finds that across 23 major APAC cities, recurring fit-outs in existing Grade A office buildings will generate between 190 and 538 million tons of embodied carbon over 60 years. The magnitude of APAC’s footprint will intensify as average lease cycles shorten and the region’s building stock grows; the region drives nearly half of global new construction through 2040.

The attention on embodied carbon in CRE is translating into increased demand for low-carbon fit-outs and transparent data to meet Scope 3 commitments.

JLL’s 2025 APAC Fit-Out Cost Survey reveals that nearly 8 in 10 APAC respondents report increased enquiries for sustainable specifications over the past two years, driven by corporate net-zero commitments and certification targets. Occupiers now demand transparent carbon data from suppliers and contractors to tackle scope 3 emissions embedded in office fit-outs.

Certification standards are raising the bar. LEED V5 ID+C now mandates embodied carbon quantification for all certified interior projects, while Australia’s Green Star Fitouts requires minimum 10% upfront carbon reduction. Investor scrutiny grows as GRESB begins scoring embodied carbon in 2026, and climate disclosure regulations across APAC progressively include scope 3 reporting.

This convergence exposes a critical gap: harmonized and verified material data. A fragmented landscape of standards and tools, each with different methodologies and recognition, complicate material comparison and selection. Data maturity varies widely across APAC, where most markets lack centralized local platforms for product-level information. Material carbon measurement and transparent data are becoming non-negotiable.

Reducing fit-out embodied carbon requires a series of coordinated interventions: optimize design to minimize material quantity, maximize circularity and reuse of existing assets, and when new procurement is necessary, specify sustainable and verified products.

Existing projects and reuse strategies demonstrate the business case for sustainable and circular fit-outs through immediate savings. An apparel company in Singapore saved S$160,000 by reusing workstations through client-to-client collaboration and transfer, while a semiconductor firm in Bangalore cut US$132,000 in costs by retaining existing chairs across its campus.

The key enabler across all projects is early engagement and cross-functional collaboration. Integrating carbon considerations before or early in the design stage enables project teams to identify optimal solutions and ensure alignment on sustainability outcomes without compromising timelines or budgets.

Individual successful projects demonstrate what is possible, yet systemic barriers to widespread adoption persist. Traditional lease structures, fragmented data systems, and underdeveloped circular supply chains demand coordinated industry action. Three key enablers are building the infrastructure for low-carbon, circular fit-outs at scale.

Progressive lease frameworks eliminate waste cycles: Forward-thinking landlords are reconfiguring standard practices. Instead of mandating full reinstatement, Dexus's "Forever Fitout" arrangement retains quality improvements for incoming tenants. Swire Properties rewards sustainable material choices and procurement of reused furniture through recognition programs.

Industry alignment on data standards creates transparency: The building industry is aligning on sustainability data standards. Notably, the Common Materials Framework provides a shared language across 150+ certifications globally, creating consistency in how carbon and sustainability attributes are disclosed.

Digital platforms make circularity visible and actionable: Digital tools are streamlining material selection. JLL Design’s Loop Library creates digital inventories of reusable assets with embedded carbon data, enabling designers to prioritize reuse before specifying new products. The platform has identified over 1,500 assets for reuse, avoiding an estimated 1.2 million kg CO₂e.

As APAC continues to experience rapid urbanization, managing material demand and its impacts becomes a key imperative in the building sector’s decarbonization pathway. CRE stakeholders who drive innovation and sustained collaboration for low-carbon and circular fit-outs will benefit from market differentiation, and resilience against material supply chain shocks.
