As can be seen in Figure 2.5, the country&#39;s emissions present an increasing trend in two periods: the first from 1990 to 1998 (compound annual growth rate of 1.3%); after which there was a decrease in total emissions of 1.9% with respect to 1998, mainly due to the effect of the economic crisis that shook Colombia from August 1998 to the end of 1999 (leading to a contraction of economic growth of - 4.2%) (Colombia between 1990 and 2008, 2009). This situation was reflected in the reduction of emissions from the energy module and IPPU in 1999 (reduction of 8% and 17%, respectively, in relation to the year 1998). The second period of growth is recorded from 2010, the year in which emissions once again reached the levels of 1999, and have grown steadily until 2018 (compound annual growth rate of 2.3%); increasing substantially during the years 2017 and 2018, presenting for 2018 there is an increase of about 25,000 Gg of CO, eq with respect to the emissions of 2016.
