51SUEZ

Environmental performance is an essential component of quality of service. The environmental objectives that SUEZ sets itself for its industrial processes aim to control their impact but also to generate a positive impact on the environment.

CARBON PERFORMANCE IN 2017 IN LINE WITH THE GROUP'S CLIMATE COMMITMENTS With a total emissions volume of 8.5MtCO2e (now calculated with a global warming potential of 28 for methane based on the recommendations of the 5th IPCC Report) and a volume of emissions avoided by its customers of 9.4 MtCO2e, the Group's carbon performance is in line with its climate commitments, which aim to reduce its carbon footprint by 30% by 2030, base-line year 2014, and to save over 60 MtCO2 for its customers by 2021. The expansion of biogas capture and recovery at landfill sites in developed countries has compensated for the increase in emissions from new centres in emerging countries not yet equipped with these systems. The increase in emissions from electricity consumption due to business growth and improvements in the quality of wastewater treatment internationally can be contained by buying green electricity, as is already the case in Spain.

TRANSFORMING TREATMENT INFRASTRUCTURE INTO RESOURCE FACTORIES As well as their primary function of protecting the environment, the facilities managed by the Group have huge potential for generating alternative resources (water, energy, secondary raw materials) and contributing to the protection of natural resources. All such opportunities must be exploited. In Spain, for example,

the Granada wastewater treatment plant has become a biorefinery: all the wastewater and sewage sludge it treats is reused in agriculture, the grease and sand produced are converted into compost and the surplus electricity that will be generated by the plant after 2020, when it will be entirely self-sufficient in terms of energy, will be injected back into the distribution network.

AN INCREASED CONTRIBUTION TO IMPROVING AIR QUALITY In line with the 2017-2021 Roadmap, the Group maintained a high level of performance in terms of NOx and SOx emissions in 2017, with average emissions respectively 60% and 40% below European requirements despite running-in periods at several waste-to-energy plants. Dust emissions were reduced by 20% on average at all the facilities managed by the Group.

MOBILISATION AGAINST WATER SCARCITY

In its 2017-2021 Roadmap, the Group once again set itself the target of saving a water quantity equivalent to the consumption of two million people over five years by reducing water leaks from drinking water networks: a population equivalent of 1.3 million was already saved in 2017 thanks to the efforts made in France, Chile and Colombia. In addition, 21.5% of wastewater treated by the Group is reused for non-food purposes.
