The EU climate package is driving changes in European and Polish law, especially regarding the implementation of numerous new or existing EU regulations governing air emissions, sulfur oxide (SOx) and nitrogen oxide (NOx) emission levels.

By January 7, 2013, EU Member States were required to follow the Directive on Industrial Emissions 2010/75/EU (IED), which was first adopted on November 24, 2010, and entered into force on January 6, 2011. The IED is of particular recent interest to power plants and installations requiring an integrated permit due to the substantial severe amendments to the allowable emission levels of SOx, NOx and dusts. The Polish government is preparing the implementation law pertaining to the IED, and expects to adopt it by the end of 2013.

The IED replaces the IPPC Directive and the sectoral directives as of January 7, 2014, with the exemption of the LCP Directive, which will be repealed with effect from January 1, 2016.
