Climate Change
Integrating climate considerations into our decisions is essential to ensure the resilience and continuity of our operations.
At OHLA USA, we incorporate climate transparency, risk management, and regulatory anticipation into our daily operations, aligning with emerging requirements in the U.S. as well as with best practices adopted by leading international companies.

Our commitment to measuring and reducing Greenhouse Gas (GHG) emissions

Measuring a company’s carbon footprint helps identify the processes and activities with the highest emissions, enabling the detection of opportunities to reduce, mitigate, or improve performance. Ultimately, the carbon footprint becomes a key tool for evaluating and advancing sustainable development. For this reason, the entire OHLA Group currently measures its carbon footprint across Scope 1, Scope 2, and Scope 3.
What we aim for:
- Reduction: Advance toward decarbonization and achieve net zero by 2050.
Specifically, we have set a target for 2031 to reduce absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 46%, and to reduce Scope 3 emissions intensity by 55%, compared to 2021. - Resilience: Strengthen our ability to respond to climate risks and seize opportunities arising from the transition.
- Neutralization: Reinforce and expand actions aimed at compensating for the portion of emissions we cannot yet eliminate.
- Disclosure: Communicate our climate action progress and results clearly and accessibly.
How we do it:
- We apply a methodology aligned with the GHG Protocol and other leading international standards (PAS 2050, ISO 14064, ISO 14069, and the Encord Construction CO₂ Measurement Protocol).
- We systematically record and consolidate emissions from our operations and value chain (Scopes 1, 2, and 3).
- We validate our targets through the Science Based Targets initiative (SBTi), which confirms that OHLA’s reduction goals align with the most recent climate science and the 1.5°C scenario of the Paris Agreement.
- We implement data control and verification processes to ensure accuracy, consistency, and traceability.
Our roadmap toward decarbonization guides our actions.
Seeking best practice in our operations
We are reducing our emissions through developing actions to optimize processes and make our use of resources more efficient.
Pursuing renewable energy
We have installed solar panels and generate green energy on certain sites.
Supporting sustainable mobility and efficient travel
We are gradually replacing our vehicle fleet with low emissions alternatives.
Offsetting our CO2 emissions
We set annual emissions offsetting plans and create carbon capture through our tree planting and reforestation activities.
In response to SB 253, which requires companies operating in California to disclose their GHG emissions, OHLA USA is strengthening its carbon footprint measurement and reporting processes with rigor and transparency.

Our commitment to climate risk management
OHLA addresses its climate resilience from the perspective of anticipation, preparedness, and effective response to the impacts climate change may have on its operations, supply chains, and long-term strategy.

For several years, the company has been conducting analyses of physical climate risks based on the latest climate models from the Coupled Model Intercomparison Project (CMIP6), specifically scenarios SSP 2-4.5 (intermediate emissions) and SSP 5-8.5 (high emissions), considering three time horizons: short term (2021–2040), medium term (2041–2060), and long term (2080–2100).
Similarly, we conduct scenario analyses to identify transition risks and climate opportunities that could affect Group activities, using the Stated Policies Scenario (STEPS) and the Net Zero Emissions by 2050 Scenario (NZE) from the International Energy Agency (IEA).
The results of these analyses, along with other progress in climate risk management, are reported annually in our Integrated Annual Report, following the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).
Our approach
As part of the OHLA Group, we adopt global best practices in climate disclosure and management, and apply them to our U.S. operations:
- We identify physical and transition risks that may affect our activities.
- We integrate these risks into our strategy, governance, and management systems, ensuring that our senior leadership and board are well informed.
- We establish metrics, targets, and action plans.
- We communicate our policies, targets, and reports to the public, anticipating regulatory timelines.
This approach enables OHLA to meet the disclosure expectations set by California’s SB 261 regarding climate-related financial risks.
