Under the legislation of the Russian Federation, all wastes across the Gazprom Group are classified as hazardous.

According to the environmental hazard classification, the bulk of the Gazprom Group’s waste belongs to Class V (almost non-hazardous) or Class IV (low-hazard) and is typically either recycled or handed over for safe placement. These two classes of wastes account for 56.6% and 38.8%, respectively, of the total waste generated by the Group.

Class I and II waste is handed over for neutralization or recycling. Its share is 0.04 % of the total waste generated by the Group.

Class III is represented, inter alia, by some of the oil-contaminated waste (that with a share of petroleum products greater than 15%). Oil-contaminated waste accounts for nearly 6.5% of the total waste generated by the Group and is handed over for neutralization or recycling.
