The burning of fossil fuels in industrial and commercial activity has been linked to the increase in the emissions of greenhouse gases in the atmosphere. Mukhopadhyay (2013) avers that the rapid industrialization over the last 60 to 70 years has contributed to the incremental increase in the emission of greenhouse gases through burning excess amounts of fossil fuels. As a result, the concentration of gases such as carbon dioxide and methane have increased in the atmosphere since the early industrialization age. According to UNFCCC (2020), the amount of emissions clocked 407.8 parts per million by 2018, which is higher than the year 2017 and the previous years. Based on the data by UNFCC, the individual sector emissions are evaluated using the global emission percentages provided by the IPCC sector (2020). Table 1 below shows the annual GHG emission contribution per sector (IPCC sector, 2020).

The data from table 1 above is represented by figure 2 below to show the pictorial representation of the sectors.
Figure 2: GHG emission by sectors (IPCC sector)
From figure 2 above, the operation of power stations, industrial processes, and transportation of fuels are the main generators of GHG emissions. In total, these industries cumulatively resulted in the emission of 72% carbon dioxide, 18% methane, and 9% nitrous oxide (IPPC sector).
