This study aims to identify sources of fluorinated greenhouse gases and evaluate the capacity needs assessment for consideration of these gases in the national GHG inventory and climate action planning for the "Climate Promise" project. These GHGs have a shorter atmospheric lifetime compared to CO2 but a high global warming potential and can warm the earth faster compared to CO2. The first stage is to identify the main sources of emissions by the mentioned greenhouse gases and collect the necessary information. The second stage is to estimate the production and consumption of these gases in the country. Depending on the data, including import, production, and consumption of gases or sales information of the devices producing these gases, we can use the Tier1 or Tier2 method to calculate the amount of emissions. Greenhouse gas emissions in 2019 were estimated at 62.3 million tons of CO2 equivalent for HFC gases, 180 Gg of CO2 equivalent for SF6 gas, and 1,130 Gg of CO2 equivalent for PFC gases. There is no information to estimate the NF3 emissions. In the last stage, solutions to reduce emissions of these gases are listed to be implemented in national development policies. The main achievement of this research is empowering the government to count these new greenhouse gases.
