The Republic of Poland has become an energy-importing country since 1986 because of increasing oil and natural gas consumption. In order to facilitate such circumstances, it promotes policies aiming at enhancing energy security, industrial competitiveness and environmental protection by furnishing the Energy Law and the related legislations in 1997. Poland works very hard to realize various international treaties in energy conservation such as Kyoto Protocol as priority because Poland's accession to the European Union is in progress. From the viewpoint of international cooperation, Poland ratified Kyoto Protocol in 2002. It is Poland's priority to endeavor the implementation and realization of energy conservation and environmental regulations of EU.
