The Intergovernmental Panel on Climate Change (IPCC) offers guidelines for calculating greenhouse gas (GHG) emissions, which are generally classified into three tiers.

As per your query, for the Tier 1 approach, you would typically use the following equation:

Emissions=ActivityData× EmissionFactor

Where:

• Activity Data is the amount of fuel consumed or the amount of activity taking place. In the case of electricity generation, this could be the amount of fuel consumed by power plants. You would typically get this data from energy statistics for the region you're studying.
• Emission Factor is a factor that converts activity data into GHG emissions. It represents the average emission rate of a given GHG for a given source, relative to units of activity. For electricity generation, this could be emissions per unit of fuel consumed. The IPCC provides default emission factors for different types of fuels and technologies in its guidelines.

To get more specific about the calculation, you would need to know the type of fuel being used (coal, natural gas, oil, etc.), and the technology being used to generate the electricity (steam turbine, gas turbine, etc.).

The IPCC guidelines provide a comprehensive list of emission factors for different fuel/technology combinations. You can find these in the "IPCC Guidelines for National Greenhouse Gas Inventories", particularly Volume 2: Energy, Chapter 2: Stationary Combustion.

As for the Long-range Energy Alternatives Planning System (LEAP), it's a software tool for energy policy analysis and climate change mitigation assessment. You can use it to build a detailed bottom-up model of a country's energy system and calculate the GHG emissions from that system. The software itself has a comprehensive user guide and there are also training videos available on the official website.

As a last point, it would be useful to look at studies or national inventory reports from countries similar to the one you are studying. These reports often provide a detailed breakdown of the methodology used to calculate emissions, which can provide useful guidance. You can often find these through a simple online search, or through databases like the United Nations Framework Convention on Climate Change (UNFCCC) GHG inventory database.

Thank you for your suggestion. I have completed the calculation part of my thesis, where I applied Equation 1 and the global warming potentials from the IPCC, to estimate the emissions of CO2, CH4, and N2O from electricity generation. I have also performed some sensitivity and uncertainty analyses to test the robustness of my results. I would like to ask you to kindly check the calculation part of my thesis. Especially, I want to confirm that I have used the correct default data and formulae for my calculations. Please let me know your email address to send the attached file of the calculation part of my thesis for your review. Thank you very much for your help and support. I look forward to hearing from you soon. Bohao He
