When the main lines of environmental performance improvement [ecologization] are implemented in the Fuel-and-Energy Complex within the period up to 2015 - 2020, the technogenic burden of the sector on environment will be significantly eased and, consequently, the overall situation in the sector is expected to improve due to increase in the production output of the Fuel-and-Energy Complex. These positive changes will facilitate the fulfillment of environmental-protection commitments, assumed by Ukraine under the relevant international covenants, and support the regulatory framework harmonization with the relevant European regulations and standards on permissible levels of negative Fuel-and-Energy Complex impacts on the environment.
