Iranian ministers of oil and foreign affairs have called upon President Hassan Rouhani to pave the way for Tehran to join the Paris Agreement on climate.

In separate letters to Rouhani, the Minister of Foreign Affairs Mohammad Javad Zarif and the Oil Minister Bijan Namdar Zanganeh have warned that it could bring negative consequences for the Islamic Republic if it stays out of the international accord.

Foreign Minister Mohammad Javad Zarif signed the Paris Agreement on climate change during a ceremony at the United Nations headquarters in New York, April 22, 2016.

“However, the agreement was brought before the Guardian Council, but the council did not approve it and proposed amendments, so the deal is now being hammered out in agriculture, water, and natural resources group of the Majles,” ISNA quoted Karim Shafie, deputy environment chief for legal affairs, as saying on Saturday.

Paris Climate Agreement, also known as Paris Climate Accord, is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions mitigation, adaptation, and finance starting in the year 2020.

“By ratifying the Paris agreement, Iran should make commitments which might put the country into significant expenses,” Karim Shafie said at the time.

Citing Shafie, Tehran Times reported, "There are proponents and opponents of the agreement in Iran. Those who are opposing the deal believe that ratifying the deal would carry considerable costs, and the costs should be funded by developed countries or international entities."

Meanwhile, Shafie argued that those who are advocating the deal believe that the it would help Iran to mitigate environmental pollutants and that Iran can mitigate greenhouse gas emission in sectors which may not carry high costs.

On June 1, 2017, President Donald Trump announced that the U.S. would cease all participation in the 2015 Paris Agreement on climate change.

Trump argued that The Paris Accord will undermine the U.S. economy and put (the U.S. at a permanent disadvantage.

Referring to President Trump's decision, oil minister, Bijan Namdar Zanganeh said in his letter to Rouhani, "Despite Washington's decision to drop the Paris Agreement, 182 countries out of 192 members of the UN, including 15 members of OPEC, have ratified the global accord, so far."

Zanganeh has argued that if the Paris agreement is fully implemented the international demand for oil will drop and Iran's exports income will be limited.

Furthermore, he has reiterated that by ratifying the international accord, Iran will benefit from the advantages it offers.
