Guide pratique pour intégrer la qualité de l’air et de l’eau dans votre stratégie RSE en entreprise

Why Integrating Air and Water Quality into Your CSR Strategy Matters

Corporate Social Responsibility (CSR) and Environmental, Social and Governance (ESG) strategies are no longer limited to carbon emissions, philanthropy or ethical sourcing. Increasingly, investors, regulators, employees and customers are examining how companies manage indoor air quality and water quality across their operations. These issues sit at the intersection of environmental impact, occupational health and operational resilience.

Clean air and safe water are now viewed as core dimensions of sustainable business performance. Poor air quality in offices, warehouses or production sites can affect employee health, reduce productivity and increase absenteeism. Similarly, neglected water quality in buildings, industrial processes or cooling systems can generate health risks, raise operational costs and undermine environmental commitments.

Integrating air and water quality into your CSR strategy is therefore both a risk management necessity and a strategic opportunity. It reinforces your employer brand, supports ESG reporting, and contributes directly to regulatory compliance and stakeholder trust.

Linking Air and Water Quality to CSR and ESG Objectives

To build a credible and effective CSR strategy, companies must translate broad sustainability ambitions into concrete, measurable objectives. Air and water quality provide tangible indicators that can be monitored, improved and communicated. They connect naturally to several CSR and ESG priorities:

• Environmental (E): Reduced pollution, responsible water use, lower chemical discharges and more efficient HVAC (Heating, Ventilation and Air Conditioning) systems.
• Social (S): Improved health, safety and well-being of employees, customers and visitors through better indoor air quality and safe drinking water.
• Governance (G): Clear policies, transparent monitoring, compliance with standards and third-party certifications for water and air quality management.

In practice, integrating these dimensions means moving from isolated technical actions to a structured approach embedded in your global CSR roadmap. It implies cross-functional collaboration between facility management, occupational health, sustainability teams and sometimes external service providers.

Assessing Current Air and Water Quality in Your Organisation

Before defining targets, it is essential to understand your current situation. A thorough assessment of indoor air quality (IAQ) and water quality highlights risks, non-compliances and quick wins. This diagnostic phase typically covers:

• Inventory of sites: Offices, industrial facilities, logistics centres, retail spaces and any location where staff or customers spend significant time.
• Existing equipment and infrastructure: HVAC systems, ventilation, filtration units, drinking water networks, cooling towers, boilers and sanitation systems.
• Current monitoring practices: Frequency of air and water testing, parameters measured (e.g., CO₂, particulate matter, temperature, pH, microbiological indicators), and service providers involved.
• Compliance status: Alignment with local regulations, occupational health requirements and building standards.

Air quality assessments often include measurements of CO₂, volatile organic compounds (VOCs), fine particles (PM2.5 and PM10), humidity and temperature. Water quality audits generally focus on microbiological quality (e.g., Legionella, coliforms), chemical parameters (e.g., heavy metals, nitrates) and aesthetic properties (taste, odour, colour).

This initial diagnostic should be documented and integrated into your CSR reporting baseline, providing a reference point for future improvements.

Defining CSR Priorities for Air Quality in the Workplace

Once you have a clear picture, you can identify where improvements in air quality will generate the greatest impact. Priorities may differ depending on your sector, building types and risk profile, but common strategic axes include:

• Employee health and well-being: Reducing exposure to pollutants and maintaining comfortable indoor conditions.
• Productivity and cognitive performance: Studies associate better indoor air quality—particularly lower CO₂ concentrations—with improved concentration and decision-making.
• Regulatory and normative alignment: Meeting or exceeding building codes, occupational health regulations and voluntary standards for indoor environments.
• Energy efficiency balance: Optimising ventilation and filtration systems to deliver good air quality while controlling energy consumption.

These themes can be translated into specific CSR objectives such as reducing the average CO₂ level in meeting rooms, introducing continuous IAQ monitoring in all large sites, or migrating to higher-efficiency air filtration technologies.

Key Actions to Improve Indoor Air Quality in a CSR Framework

A practical CSR-focused air quality strategy often combines technical upgrades, operational routines and awareness initiatives:

• Optimised ventilation: Adjusting air renewal rates, increasing fresh air intake when necessary, and ensuring regular maintenance of ventilation ducts and fans.
• Filtration and purification: Installing or upgrading filters in HVAC systems (e.g., HEPA or high-MERV filters), and where appropriate, using localised air purifiers in high-occupancy zones.
• Material and product selection: Limiting VOC emissions by choosing low-emission paints, flooring and furniture, and using cleaning products that are both effective and environmentally certified.
• Sensor deployment and monitoring: Integrating connected IAQ sensors across critical buildings to capture real-time data on CO₂, particles and humidity, and connecting these systems to building management platforms.
• Maintenance and inspection plans: Defining regular inspection schedules for filters, ducts and equipment to prevent accumulation of dust and microorganisms.
• Occupant engagement: Informing employees about ventilation practices, the importance of not blocking vents, and the role they can play in maintaining a healthy indoor environment.

By embedding these measures into your CSR action plan, you can link tangible improvements in indoor air quality to measurable ESG indicators.

Embedding Water Quality Management into CSR Strategy

Water is central to sustainability discussions, yet water quality at the building and process level is sometimes overlooked. A robust CSR approach should address not only water consumption but also the quality of water used and discharged throughout your facilities.

Key dimensions include:

• Drinking water safety: Ensuring that taps, fountains and dispensers provide water that consistently meets or exceeds legal standards.
• Health risk control: Implementing systematic programmes to prevent waterborne pathogens, particularly Legionella in hot water systems and cooling towers.
• Process and industrial water: Managing water quality in production lines to protect products, equipment and the environment.
• Wastewater and discharge quality: Treating and monitoring effluents to comply with regulations and CSR commitments related to local ecosystems.

Integrating these elements into your CSR strategy involves both technical investments and clear governance, with defined responsibilities for facility management, health and safety and environmental teams.

Practical Steps to Improve Water Quality in Corporate Environments

Several practical actions can be implemented progressively to reinforce your CSR performance on water quality:

• Comprehensive water audits: Mapping all water points, networks and critical equipment, and identifying areas with elevated risk or outdated infrastructure.
• Regular sampling and analysis: Establishing a testing schedule aligned with regulatory requirements and internal standards, including microbiological and chemical parameters.
• Legionella risk management: Creating and maintaining Legionella control plans for hot water systems, cooling towers and other risk installations, with documented procedures and periodic inspections.
• Filtration and treatment systems: Installing or upgrading filters, softeners, UV disinfection or other treatment technologies where water quality is inconsistent or where sensitive uses are involved.
• Infrastructure maintenance: Replacing obsolete pipes or corroded components, cleaning storage tanks and ensuring proper protection against backflow and contamination.
• Responsible wastewater management: Monitoring effluent quality, optimising treatment systems and exploring options for reuse or recycling where feasible.

These interventions can be integrated into a phased investment plan, prioritised by risk level and potential CSR impact.

Monitoring, KPIs and Reporting for Air and Water Quality

To ensure accountability and demonstrate progress, your CSR strategy needs clear indicators related to air and water quality. Common Key Performance Indicators (KPIs) include:

• For air quality: Average CO₂ levels in occupied spaces, percentage of time IAQ metrics remain within defined comfort thresholds, proportion of buildings equipped with continuous monitoring, frequency of filter replacements and number of IAQ incidents recorded.
• For water quality: Compliance rate of drinking water tests, number of Legionella non-conformities detected, volume of water treated or reused, and percentage of sites with updated water risk assessments.

These KPIs should be aligned with recognised frameworks where possible, such as GRI standards, SASB indicators or national CSR guidelines. Integrating water and air metrics into annual sustainability reports, non-financial statements and ESG disclosures increases transparency and allows stakeholders to track your performance over time.

Engaging Stakeholders and Selecting Service Partners

Implementing a robust air and water quality strategy requires coordinated action across internal teams and external partners. Internally, involving facility managers, health and safety officers, HR and sustainability experts ensures that technical, human and regulatory aspects are all considered.

Externally, specialist service providers—such as environmental laboratories, water treatment companies or indoor air quality consultants—can support diagnostics, system design, maintenance and performance verification. When selecting partners, companies typically evaluate:

• Technical expertise in air quality monitoring, HVAC optimisation and water treatment.
• Certifications, accreditation of laboratories and compliance with relevant standards.
• Ability to provide digital reporting tools, dashboards and data integration for ESG reporting.
• Experience in multi-site corporate projects and capacity to support long-term improvement plans.

Involving employees and, where appropriate, tenants or visitors also reinforces the legitimacy of your CSR actions. Sharing monitoring results, explaining measures taken and encouraging feedback can turn a purely technical programme into a shared commitment to health and environmental quality.

Positioning Air and Water Quality as a Strategic CSR Differentiator

In competitive markets and tightening regulatory environments, demonstrating advanced management of indoor air quality and water quality can become a differentiating element of your CSR strategy. Beyond compliance, it signals a tangible investment in health, safety and environmental stewardship.

Companies that proactively address these topics often benefit from stronger ESG ratings, improved employee satisfaction and a more resilient operational model. For organisations integrating sustainability into their core business model, air and water quality are no longer peripheral issues—they are essential levers to align environmental responsibility, social performance and long-term value creation.
