CO emissions from lime production were recalculated for the period 1990-2016 as a result of updating the activity data on the amount of lime produced by auto-producers (in the current inventory cycle, information from sugar factories Sudzucker-Moldova SRL and Moldova-Sugar Ltd. were received, the market share of these two enterprises varied in the period 2013-2019 between 92.6 and 99.9 per cent of the total amount of sugar produced in the Republic of Moldova). Compared to the values recorded in BUR2 of the RM to the UNFCCC (2019), the changes undertaken resulted in an upward trend in CO emissions in the period 1990-2000, ranging from a minimum increase of 2.1 per cent in 2000 to a maximum increase of 13.7 per cent in 1990; respectively, in a tendency to reduce CO emissions in the period 2001-2016, varying from a minimum decrease of 0.3 per cent in 2001 to a maximum decrease of 39.2 per cent in 2014. CO emissions from lime production for the years 2017-2019 were calculated for the first time. In the period 1990-2019, CO emissions from lime production decreased by about 89.6 per cent (Table 4-36).
