Zaključilo se je 23. zasedanje držav pogodbenic Konvencije o varovanju morja in obal Sredozemlja – Barcelonske konvencije – COP 23 (angleško Conference of Parties – COP). Pogodbenice so sprejele več pomembnih zavez za zaščito Sredozemlja ob vse večjem vplivu podnebnih sprememb, zmanjševanju biotske raznovrstnosti in onesnaženju. V ospredju COP 23 je bila vključenost mladih v procese odločanja.

"When it comes to the environment, there are no borders. There is only one environment, and that is the environment of our planet. We must take action and we must act globally. You will be proud of what Slovenia is going to stand for in the next two years," Prime Minister Dr Robert Golob told the delegates gathered at the 23rd Meeting of the Contracting Parties to the Barcelona Convention – COP 23, as Slovenia takes over the Presidency.

On the second day of the meeting of 21 contracting parties to the Barcelona Convention, which is currently ongoing in Portorož, the Delegates focused on marine spatial planning, ballast water management and inert waste disposal. Today, the countries also completed the final content harmonization of the Portorož Declaration, which will be adopted at tomorrow's ministerial meeting. The countries also support the idea of establishing a new regional climate change centre.

All passengers entering Slovenia by aircraft or cruise ship will have to fill out a Digital Passenger Locator Form (electronic PLF form - dPLF) from 16 August 2021 before entering the country.
