- Leaving the ETS altogether is impossible. These are EU rules, concerning the common energy market, where we sell energy, export, import, and where immense chaos would arise, because there are uniform rules binding everyone. If someone suddenly wanted to withdraw from the prevailing rules there, essentially one could say they couldn't be a player on that market. Therefore, we wouldn't be able to export surplus energy or import energy from neighboring countries - said Paulina Hennig-Kloska on TVN24's "Fakty po Faktach" program.
