Turkey, like neighbouring Iran, is one of the few countries that has signed but not ratified the Paris Agreement, in other words it is a signatory but not one of the parties to the agreement. The main opposition Republican People's Party has called for the agreement to be ratified. Other countries are likely to press Turkey at the 2021 G20 and climate change summits. The EU is urging Turkey to ratify the agreement. Turkey is not party to the Convention on Environmental Impact Assessment in a Transboundary Context (Espoo Convention). Similarly Turkey has signed but not ratified the Kigali Amendment to reduce production and use of hydroflourocarbons. It has no carbon tax or emissions trading scheme, therefore carbon capture and storage is not used as it is not economically viable. Armenia says that dam construction in Turkey has combined with climate change to reduce flow in the Araks River basin.
