Table A 1 (continuation) Second National Communication Series 1990-2002 (even years) Energy Categories and subcategories of aggregate estimated source in Energy Industries Categories and subcategories of aggregate estimated source in manufacturing and construction industries Consumption data for various aggregated fuels Data corrected for oil consumption generated, which generates inconsistencies in the emi-crude, fuel oil, diesel and natural gas in energy produc- tion Incomplete disaggregation of fuel consumption in transport Incomplete disaggregation of fuel consumption in the Fugitive Emissions category (oil and natural gas) Better disaggregation of fuel consumption for transportation thanks to access to the National Energy Balance No estimate of emissions in other types of Estimation of emissions in the transport subcategory All-terrain transport in mobile agriculture Incomplete estimate in the Residential, Commercial/Institutional and Agriculture/Forestry and Fisheries sectors Deficient review process by external experts Third National Communication Series 1990-2016 Source categories and subcategories disaggregated (Emissions from electricity generation and oil refining were disaggregated in the Energy Industries subcategory. No estimate of emissions in many categories and subcategories due to unavailability of activity data Activity data from clinker production only for even years and default emission factors Emissions were disaggregated for 4 of the 13 components of the subcategory More detailed disaggregation of fuel consumption in the Fugitive emissions category that allowed determining that they were underestimated emissions in this category IPPU More detailed estimate of emissions from 1.A.4. Other sectors Comparative studies with results from other institutions in the electricity generation sector (eg Cubaenergia) Increase in completeness when declaring the Non-Occurrence of emissions in some subcategories, especially in the chemical industry and the completion of data series of activity on the annual production of some substances The series of activity data on clinker production is completed for all the years of the series. The annual parametric data on the proportion of calcium oxide in the clinker is obtained, which makes it possible to obtain an annual emission factor specific to the country.
