Air quality plays a critical role in public health, liveability and productivity. WSP supports governments, cities and businesses with integrated, evidence-led air quality solutions, from policy and planning through to permitting, monitoring, modeling, implementation and Net Zero integration.

How we help

Strategy, policy and investment

We support clients in shaping robust air quality strategies, policies and action plans that respond to regulatory requirements while delivering wider benefits for health, climate and place. 

Our work includes air quality plans at city, regional and national-scale, support for clean air zones and low emission zones and the appraisal of mitigation options. By combining technical evidence with health and economic assessment, we help clients build strong investment cases and secure support for long term delivery.

City scale and infrastructure delivery

We integrate air quality considerations into urban development, transport, infrastructure and industrial systems. Our teams deliver city wide air quality management programs that bring together emissions inventories, modeling and scenario testing to support informed, place based decision making.

This integrated approach helps clients design solutions that are practical, proportionate and focused on achieving real improvements where they matter most.

Monitoring, modelling and digital solutions

Reliable data underpins effective air quality management. We provide end to end monitoring, modeling and digital solutions - and, where regulatory frameworks allow, that give clients confidence in their evidence base and clarity in their decisions.

Our services include the design and operation of monitoring networks, quality assured data management, advanced modeling across multiple spatial scales, forecasting services, and interactive dashboards and platforms that support both professional users and public communication.

This includes the use of established digital tools and platforms, such as WSP’s RapidAir, MODUS and emissions inventory solutions, alongside bespoke modeling and analysis.

Decarbonization, Net Zero and health co- benefits

We integrate air quality expertise with climate, transport, energy and sustainability strategies to support joined‑up, evidence‑led decision‑making. By aligning air quality improvement with Net Zero pathways and low‑emission strategies, we help clients protect public health, reduce environmental risk and make progress against wider climate and resilience objectives.

Capacity building and knowledge transfer

Long term success depends on organizations having the confidence and understanding to apply air quality insights in practice.

We support organizations through tailored training, tools and knowledge sharing initiatives that help embed air quality management into everyday decision making.

Our approach focuses on building confidence across teams and stakeholders, ensuring that solutions are understood, trusted and sustained over time.

A structured, evidence-led approach from insight to impact

Air quality challenges sit at the intersection of health, policy, infrastructure and behavior. Our approach brings together strategic insight, robust science and practical delivery to help clients move from understanding risk to achieving measurable improvement.

We work with clients through a clear, flexible framework that supports confident decision-making and long term outcomes, whether at local, city, regional or national scale.

This lifecycle lens is particularly valuable for major infrastructure and development projects, including airports, transport corridors and large scale developments, where air quality considerations influence planning, design, construction and operation.

Understand context and priorities

We build a robust understanding of local conditions, emissions sources, health impacts and regulatory drivers. This includes developing or reviewing baseline data, policy context, and governance arrangements to identify where intervention will deliver the greatest benefit.

Build the evidence base

We develop the technical evidence needed to support decision-making using monitoring, emissions inventories, modeling and analysis across appropriate spatial scales. All work is grounded in quality assured, defensible data.

Assess options and co-benefits

We evaluate mitigation options and scenarios, considering air quality outcomes alongside health, economic, climate and wider environmental co-benefits. This enables proportional, cost effective prioritization and the development of robust investment cases.

Monitor, communicate and adapt

Air quality management is an ongoing process. We support performance tracking, transparent communication and adaptive management as conditions, evidence and expectations evolve.

Why this approach works

  • Evidence-led: Grounded in robust data, modeling and analysis
  • Policy-informed: Aligned with regulatory and planning frameworks
  • Integrated: Linking air quality, health, climate and place
  • Outcome-focused: Designed to deliver measurable improvement

Frequently Asked Questions

Who do you support with air quality services?

We work with governments, cities, transport authorities, infrastructure owners, developers and private organizations to manage air quality risks and deliver measurable improvements for health, environment and place.

Can you support policy and regulatory processes?

Yes. We regularly support the development of air quality strategies, action plans, Clean Air Zones, Low Emission Zones and Ultra Low Emission Zones, as well as providing evidence and analysis to inform planning, regulatory decisions and funding cases.

How do you combine air quality with Net Zero and climate objectives?

We design air quality actions so they reinforce decarbonization, not compete with it. By aligning interventions such as traffic reduction, modal shift, cleaner energy and industrial emissions controls, we help clients deliver air quality improvements alongside carbon reduction, public health benefits and wider environmental co benefits.

Do you provide monitoring and modeling services, or only advisory work?

We deliver a full range of air quality services, including monitoring network design and operation, emissions inventories, advanced modeling, forecasting and digital reporting platforms, alongside strategic advisory support.

At what scale do you support air quality management?

We work across all spatial scales, from national policy and regulatory support, to regional and city wide air quality programs, through to site specific and asset level assessment, monitoring and modeling, including detailed studies to inform individual planning applications or operational decisions.

How do you ensure your recommendations are practical and deliverable?

Our approach combines technical evidence, policy insight and implementation experience. We work closely with client teams to ensure solutions are proportionate, cost effective and suited to local context, governance and capacity.

Do you support long‑term monitoring and reporting?

Yes. Air quality management is an ongoing process. We support performance tracking, public reporting, regulatory compliance and adaptive management as conditions, evidence and expectations evolve.
