Air quality

In addition to CO2, other emissions are produced by the combustion of fossil fuels during the industrial processes involved in energy production. Depending on their concentration in the air, nitrogen oxide (NOx), sulfur dioxide (SO2) and particulate matters (PM) can have a serious impact on the environment and human health.


Actions on plants

The regulatory framework for air emissions is changing rapidly in many countries, leading to a significant increase in the constraints on the main pollutants (NOX, SO2 and PM). The level of requirement remains however very variable according to the regions of the world.


Focus on Europe

The 2010/75/UE Directive related to industrial emissions (IED Directive) adopted in 2012, and the European Commission's Best Reference (BREF) document identifying the best techniques for Large Combustion Plants adopted in 2017, are the two basic texts for industrial emissions in Europe. These impact the ENGIE facilities and the Group's industrial customers.


ENGIE is committed, according to the regulations, to implement the best available techniques on the different sites of energy production in order to reduce emissions as much as possible.


Actions in cities and territories

Qualité de l’air

Beyond the actions implemented on energy production sites, ENGIE proposes offers to support cities and territories in the implementation of actions to improve air quality. These actions may relate to transport, flow management, or support in the implementation of the energy transition.


Example: the city of Rio de Janeiro and its conurbation have invested in a smart traffic management system to relieve road congestion and make traffic smoother, which helps to reduce air pollution link with the road traffic. 


Actions for employees: green mobility plans

In France, the Law on energy transition for green growth published in August 2015 requires each company with more than 100 employees on the same site integrated in a city travel plan to implement green mobility plans to change the habits of employees, by promoting public transport and other alternative modes (carpooling, cycling, car-sharing, etc.). This makes it possible both to improve the quality of life of the employees and to reduce the emissions related to the transport, which is the main source of pollution in the agglomerations.


ENGIE is committed to implementing these green mobility plans and thus reducing emissions related to business travel.


Actions beyond traditional techniques

Plant and fungal biomonitoring

Beyond traditional monitoring of emissions from the stack, plant and fungal biomonitoring makes it possible to observe and map the impact of industrial sites in their area of influence, and thus to identify possible risk areas requiring improvements at the site level.


This method has already been applied in several Group entities including Storengy.


Purification of indoor air with artificial intelligence

Qualité de l’air

Purification of indoor air with artificial intelligence DIYA ONE, the robot developed by Cofely Services and Partnering Robotics. It adapts to different environments in a fluid and dynamic way. It moves in each room of a building in complete autonomy to purify the air and collect data allowing the control of energy efficiency services for example.
