    Hi,
    I have built a model (let's call it Model A)for a city, and found the results of some air pollutants (like SO2 and NOx) other than GHG are unavailable in the "Environment" of result frame (Figure 1).
    I'm now using LEAP Version: 2017.0.5.0, and model (let's call it Model B) I built with previous version of LEAP before is fine with this version of LEAP. As you can see in Figure 2, the results of the air pollutants are available here. I'm sure the emission factor of SO2 has been added (Figure 3). How can I solve the problem?
    Besides, is there PM 2.5 emission factor in the environment database of LEAP? Because I didn't see it (Figure 3).

    Figure 1. The result of other pollutants doesn't show up in Model A with new version LEAP and previous version of LEAP


    Figure 2. The result of other pollutants doesn't show up in Model B with new version LEAP


    Figure 3. The emission factor has been added in the analysis frame of Model A

    Hi Jie-Feng,

    Have you ensured that all of the emissions results are being calculated? To check this, in Analysis View go to General>Results to Save, and ensure the "Other Environmental Loadings" results are checked.

    LEAP's Technology and Environmental Database (TED) is based on a literature review of published estimates of emission loadings and does not currently contain a comprehensive picture of all effects from each of its source categories. Therefore, it is possible that PM 2.5 emission factors are not listed in TED for the process you are interested in. However, you can manually add emission factors in the "Environmental Loading" tab of a feedstock fuel (as shown in Figure 3 from your post). Select the green "plus" (+) sign on the right side to add a new loading of your choice.

    For more information on environmental loadings, refer to the following help page: https://www.energycommunity.org/Help/Demand/Environmental_Analysis.htm

    Hope this helps!

    Emily
