Indoor air quality: taking up the challenges of air pollution

Air quality and the impact of atmospheric pollution are a major issue today for public health and quality of life: more than 8 million premature deaths worldwide are reportedly due to air pollution, of which 3.8 million are attributed to indoor air pollution in homes, according to the WHO.

In the same way that Veolia has made access to drinking water a major driver for public health and quality of life, our Group has decided to apply its expertise and solutions to improving the quality of indoor air.

Air-quality: a public health and quality of life issue worldwide

 

“Invisible” and complex pollution

Air pollution is the contamination of the indoor or outdoor environment by a chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.

Measured by a combination of chemical and electronic methods, air quality is assessed and evaluated using regular monitoring. Increasingly effective sensors and analyzers are connected to a computer system, which records readings at regular intervals. These readings are used to quantify the level of atmospheric pollution in the monitored area.

In France, this monitoring is conducted for outdoor areas by a series of associations (AASQA or approved air quality monitoring associations).

According to ADEME (French Environment and Energy Management Agency), there is no “barrier” between outdoor air quality (OAQ) and indoor air quality (IAQ), as IAQ depends in part on OAQ. While specific measures can and should be introduced to protect and improve indoor air quality, those targeting outdoor air quality automatically have an effect on indoor air quality.

 

A major public health concern

Air pollution is one of the main environmental risks worldwide. According to the WHO, it was the cause of more than 8 million premature deaths worldwide in 2016. Again, according to the WHO, this would make it the fourth major risk of fatality in the world. Furthermore, the air inside a building is no less polluted than the air outside, even though we spend more than 85% of our time in enclosed spaces.

The results of the 2019 Elabe study for Veolia concerning this issue in France, Belgium and greater Shanghai (China), are significant in this respect: one out of two French, and even more than 60% of Belgians and Shanghai residents are surprised to learn that we are more exposed to pollution in the air inside our homes and the buildings that we frequent than outdoors.

In the same way that Veolia has made access to drinking water a major driver for public health and quality of life, our Group has decided to apply its expertise and solutions to improving the quality of indoor air.

 

NoUsing our unique expertise to respond to indoor air quality issues

The expertise we have acquired in our water, waste and energy businesses, allows us to respond to air-quality issues, in particular using our expertise in the areas of:

  • managing atmospheric emissions from our incineration and hazardous waste technologies
  • managing odors emitted by wastewater treatment plants
  • auditing and measuring the health quality of water and air flows inside buildings.ts

Additionally, our expertise in managing the energy efficiency of facilities gives us legitimacy in the area of indoor air quality, which is intimately linked to a building’s energy management.
With our experience, we can guarantee our clients quality air at an optimum cost.

Pollution and its consequences in a few figures

Current figures (Source: WHO - 2018)

  • In 2016, 8 million deaths were attributed to air pollution => 4.2 million premature deaths attributed to outdoor air pollution and 3.8 million premature deaths attributed to indoor pollution in homes.

  • In 2016, 91% of the world’s population lived in places where the WHO air quality guidelines were exceeded.

  • In 2015, the health cost of air pollution was estimated to be $21 billion and air pollution was reported to account for 1.2 billion days loss of productivity (Source: The economic consequences of outdoor air pollution, OECD, September 2016).

2060 forecast:

  • Up to 9 million premature deaths per year (Source: IHME: Institute for Health Metrics and Evaluation

  • Air pollution could cost up to 1% of global GDP in 2060 (the impact on labor productivity, health costs and agricultural crop yields would lead to a gradual increase in global economic costs of up to 1% of global GDP) (Source: OECD)

  • Each year, the expected health costs would be $176 billion and the impact on productivity has been assessed at 3.7 billion days lost (Source: The economic consequences of outdoor air pollution, OECD, September 2016).

A lead contractor and integrator guaranteeing exemplary air quality

 

Veolia’s purpose is to contribute to human progress by adopting a concerted approach to the UN’s Sustainable Development Goals. It must therefore take into account all types of pollution including those that are not yet well known or managed by the general public.

With its expertise in energy services, Veolia already helps its clients reduce their ecological footprint (energy efficiency, effective management of facilities, etc.).

Veolia offers its clients an air quality guarantee, which others do not yet offer.

The Group acts as a lead contractor and integrator for all the components needed to guarantee its clients – public or private building managers – exemplary air quality for the health of their occupants or users, and to comply with energy efficiency and asset improvement issues. Veolia covers the entire IAQ value chain: audit and diagnosis to define the situation, manage facilities with continuous monitoring, supply and install appropriate systems to treat air or remove pollution, and to involve occupants in improving a building’s air quality.

Specific products and solutions

Veolia: has for many years been developing indoor air quality solutions:

  • Audits, diagnostics and recommendations including the audit of air treatment facilities
  • Rollout and management of action plans including equipment improvement programs
  • Crisis management systems
  • Reporting.

Today, Veolia provides its clients with a new offer to improve their indoor air quality.

This offer includes three different service modules: AIR Control, AIR Performance and AIR Human.

They have been developed for each type of client (offices, schools, medical centers, shopping malls, hotels, etc.), in order to factor in their various needs and specific expectations.

​Veolia mobilized alongside the UN

 The Group is urging all its employees worldwide to take part in the Air quality challenge organized with the support of UN Environment and the Veolia Foundation. All employees are encouraged to go to work using an eco-responsible form of transportation: walk, bike, scooter or mass transit. A tree will be planted for each of these green trips.

The Veolia Foundation is also supporting the “It’s Our Air” educational kit produced by UN Environment for junior and senior high school teachers to raise teaching staff and students’ awareness of the fact that air quality is the greatest risk in terms of environmental health.

This kit is available in French, English and Chinese and will be distributed from June 5 by UN Environment and UNESCO through their partner school network.
