This article explains the scale of construction industry carbon emissions, clarifies the main drivers, and outlines proven, actionable ways to reduce them.
Understanding construction industry carbon emissions: Scope, impact, and urgency
Construction industry carbon emissions account for a significant share of global climate impact.
Buildings and construction together account for roughly 37–39% of global energy‑related CO₂ emissions, depending on the exact scope and year [IEA 2023, UNEP GlobalABC 2022]. Of this, around 28% comes from building operations and about 7–11% from the production and construction of building materials (embodied carbon). This combined 37–39% makes buildings and construction a top priority for decarbonization.
Global construction CO₂ emissions stem from every stage of the value chain, from raw material extraction to energy used in buildings over decades of operation.
Population growth and urbanization put even greater pressure on the sector. As the world approaches 10 billion people by 2050, global building floor area is expected to double relative to 2020 levels (UNEP GlobalABC 2022). Without decisive action, raw material consumption and the associated construction greenhouse gas metrics are set to rise dramatically.
Breaking down the main sources reveals two fundamental categories: operational carbon and embodied carbon.
- Operational carbon reflects the emissions from running existing buildings – such as heating, cooling, lighting, and appliances. This operational footprint currently accounts for 28% of total energy-related emissions (IEA 2023).
- Embodied carbon, by contrast, includes all emissions generated during the construction lifecycle, including raw material extraction, transportation, manufacturing, assembly, refurbishment, and end-of-life phases. This embodied footprint accounts for 7-11% to global emissions.
The following table clarifies the main contributors to construction sector carbon dioxide metrics based on the latest analysis of building CO2 outputs (IEA Global Status Report 2023):
| Source | Emissions (Gt CO₂) | % of global total |
|---|---|---|
| Building operations (energy use) | 9.0–9.5 | ~25% |
| Building and construction materials (embodied carbon) | 3.5–4.0 | ~11% |
| Total buildings & construction (combined) | ~13.5 | ~36% |
A $13 trillion value chain and the urgency of global climate targets make it clear: reducing construction industry carbon emissions is essential for every business in the sector. Action now delivers both compliance and competitive advantage as expectations from regulators, investors, and customers continue to rise.
Key drivers of carbon emissions in construction projects
Accurate building material carbon footprint calculations, supply chain carbon impact analysis, and environmental impact of construction inputs are essential for pinpointing the most carbon-intensive phases. This enables sustainability and product teams to select lower-impact materials, optimize designs, and engage suppliers to reduce upstream emissions.
- Material production and processing: The lifecycle footprint of concrete, carbon factors in steel structures, and the manufacturing of aggregates drive most embodied carbon.
- Building operations: Day-to-day energy use for HVAC, lighting, and equipment creates a high operational footprint over the asset’s lifetime.
- Transportation and logistics: Emissions from moving materials to site and distributing finished components along the supply chain.
- Construction site activities: Machinery, generators, and on-site processes add to total emissions, though this phase is typically less significant than material production.
- End-of-life and refurbishment: Demolition, recycling, and disposal processes contribute to the overall carbon impact but are often overlooked in early-stage planning.
By focusing on these emission drivers, business users can prioritize reduction strategies that have the greatest effect on both compliance and environmental performance.
Global trends and data: Construction CO2 emissions benchmarks
Global construction CO2 emissions remain a central focus for climate action and regulatory policy. As mentioned earlier, in 2023 the buildings and construction together accounted for approximately 39% of global energy-related emissions, highlighting the industry’s influence on international climate objectives. The Paris Agreement’s mandate to keep global warming “well below 2 degrees Celsius” has intensified the need for strict carbon management across construction projects.
Industry emissions data for construction makes it possible to evaluate sector performance and create actionable targets. Companies now use sector-specific CO2 benchmarks to measure and compare their progress against international standards. Performance metrics for construction emissions support continuous improvement, allowing teams to set reduction goals and demonstrate compliance to regulators and stakeholders.
Industry surveys consistently reveal that construction leaders expect major sustainability transformations within the next five years, primarily in response to evolving regulation and competitive pressure. Embracing emissions benchmarking and transparent metrics positions construction businesses to meet both compliance requirements and stakeholder expectations for sustainability leadership.
| Year | Global construction emissions (Gt CO2) | % of total energy-related emissions |

Benchmarking against these construction sector carbon dioxide metrics enables organizations to track carbon emissions trends in construction and make informed, data-driven decisions for sustainable growth.
Regulatory compliance and carbon emission reporting for construction
Construction businesses face rising expectations to track and disclose their carbon footprint. Regulatory compliance for emissions is now a core requirement, not just an option. New and evolving construction sustainability regulations demand that companies collect accurate, lifecycle-based data for every project, covering both direct and supply chain impacts.
Carbon disclosure in projects is driven by a combination of global and regional rules. Regulations such as the Corporate Sustainability Reporting Directive (CSRD), Carbon Border Adjustment Mechanism (CBAM), and the Ecodesign for Sustainable Products Regulation (ESPR), are all setting the standard for CO2 reporting in building and construction. Lifecycle-based emissions data is now essential for Environmental Product Declarations (EPDs), a key step for compliance with the Energy Efficiency in Buildings Directive and other market-entry requirements.
Motivations for carbon footprint reporting go beyond legal obligations. Investors and customers expect transparency, while financiers increasingly link project funding to credible decarbonization data. Accurate reporting can drive financial efficiency, unlock new market opportunities, and build a reputation for responsible business practices.
Integration of emission monitoring systems into business management processes is now expected. Automated data collection and standardized reporting frameworks help business users meet these requirements without needing specialist expertise.
- Product emissions reporting for EPDs (Environmental Product Declarations)
- Annual sustainability reporting under CSRD and similar directives
- Supply chain carbon data for CBAM and cross-border trade
- Compliance with energy efficiency and building performance regulations
Meeting these carbon footprint reporting standards positions construction businesses to respond confidently to regulatory drivers for decarbonization and stay ahead in a market where compliance and credibility are business essentials.
Best practices for reducing carbon emissions in construction projects
