Major emissions are from diesel power plants.

Major water consumption was for household and drinking needs (65%), industrial needs — 35%.

Waste generation was observed to decrease in 2015 as compared to the previous years, mainly for the waste of hazard classes 4 and 5.

The branches of PJSC IDGC of the North-West develop environmental projects on an annual basis. A focus is on collection and transfer waste of hazard class 1 to 4 to  specialized companies licensed for waste decontamination and disposal. Completed activities are monitored on an ongoing basis.
