Air quality and environmental performance: an integrated approach for a sustainable future

In a context where the ecological transition is becoming imperative for businesses, communities, and citizens, NUMTECH is fully committed by combining scientific expertise and concrete actions.
We place two complementary areas at the heart of our strategy: air quality studies and improving our environmental footprint.
Far from being independent, these two areas of action are closely linked and mutually reinforcing.

Air quality modeling: a tool for understanding and forecasting

Historically specializing in air quality modeling, NUMTECH develops and uses high-performance modeling tools to simulate atmospheric pollutant concentrations at different scales (local, urban, regional). These simulations, based on meteorological, topographic, and emissions data, allow us to:

• Identify major sources of pollution (road traffic, industry, heating, etc.),
• Assess the impact of human activities on the environment and health,
• Simulate development or transition scenarios (emissions reduction).

This information provides a detailed, local, and dynamic view of the situation. It is therefore an essential decision-making tool for guiding public policies and business strategies toward more sustainable choices. It also helps in planning effective actions that comply with air quality regulations.

Environmental performance: towards a more holistic approach

Air quality is one of the most direct and measurable indicators of our impact on the environment. Air pollutants, particularly those from transportation, industrial activities, and heating, do more than just degrade the air we breathe; they have broader effects on ecosystems and the climate.
Faced with the growing challenges of climate change and the pressure on resources, it is essential to adopt a broader perspective on our environmental impacts.
It is with this in mind that NUMTECH has, for several years, expanded its long-standing expertise in atmospheric modeling with an integrated approach, enabling the comprehensive, rigorous, and structured assessment and management of environmental performance. Our services include:

• BCarbon Footprint Assessments (Bilan Carbone®), which allow for the quantification of an organization's greenhouse gas emissions,
• Life Cycle Assessments (LCAs) evaluate the environmental impacts of products or services throughout their life cycle. These analyses cover multiple criteria: climate change, water, resource and energy consumption, air pollution, and many others.
• Several support around climate strategies, decarbonization, eco-design and CSR approaches.

A synergy in service of action

Our approach is based on a strong conviction: you can only improve what you understand.
By combining atmospheric modeling and multi-criteria assessment, we build a coherent and comprehensive understanding of environmental impact.
Our clients can act on both local air quality and major global challenges such as climate and resources, aligning their actions with the most relevant environmental priorities.
Our strength lies in the interconnection between these two areas of expertise. Data from atmospheric modeling enriches our environmental analyses, and vice versa; our LCAs provide a broader understanding of the impacts of atmospheric emissions.
This integrated approach allows us:

• to propose technically credible and environmentally relevant optimization scenarios,
• to support our partners in a concrete transition process, based on science and innovation.

At NUMTECH, air quality is not seen as a separate issue, but as a key indicator and driver of environmental performance. By combining our expertise in atmospheric modeling, environmental assessment, and structured management, we design integrated solutions that provide a 360° view, enabling us to act faster and more effectively, in service of development that is more respectful of the environment and everyone's health.

Conclusion: An integrated approach to sustainably support our clients' transition

By leveraging the right tools and expert support, our clients can combine performance, regulatory compliance, and reduced environmental impact.
NUMTECH is committed to working alongside them to build a more sustainable future together.
