On the basis of national capabilities, financial resources available and requirements of the national development program, taking into account GHGs emission scenarios, the Islamic Republic of Iran intends to participate by mitigating its GHGs emission in 2030 by 4% compared to the Business As Usual (BAU) scenario. This level of unconditional emission reduction will be achieved through development of combined cycle power plants, renewable energies and nuclear power, as well as reduction of gas flare emissions, increasing energy efficiency in various consuming sectors, substituting high-carbon fuels with natural gas, strategic planning for utilizing low-carbon fuels, intensifying economic diversification and participation in market-based mechanisms at the national and international levels. Subject to termination and non-existence of unjust sanctions, availability of international resources in the form of financial support and technology transfer, exchange of carbon credits, accessibility of bilateral or multilateral implementation mechanisms, transfer of clean technologies as well as capacity building, the Islamic Republic of Iran has the potential of mitigating additional GHGs emission up to 8% against the BAU scenario (i.e. 12% in total).
