“…This involves the physical removal of impurities such as sulfur, mercury, and ash from raw coal before it is burned, thus mitigating the release of harmful pollutants (Oberschelp, Pfister, Raptis, & Hellweg, 2019). Advanced techniques, including coal washing and chemical cleaning, enhance the efficiency of this process, yielding cleaner-burning coal (Lee, Kim, Chun, Choi, & Yoo, 2017). Employing Carbon Capture and Storage (CCS) technologies postcombustion captures carbon dioxide emissions at their source (Ding, Wei, & Yu, 2020), preventing them from entering the atmosphere.…”

This paper considers the ethical dilemma posed by the Paris Climate Agreement considering the abundant coal exploitation opportunities in Botswana. The estimated 200 billion tons of coal was initially viewed as an opportunity to diversify the Botswana economy away from diamonds. Coal is currently used locally for electricity production and other small scale domestic uses. This paper mainly discusses thermal coal as opposed to coking coal commonly referred to as Met-coal. Lucrative prices on world markets coupled with demand in India and China for coal, Botswana with its massive coal deposits, one of the largest in world, can develop a new export sector which would diversify the diamond dependent economy. In 2012 the Government of Botswana released a Coal Road Map as it then envisaged coal as one of the more propitious areas for economic diversification. However, the potential to develop this export sector has been seriously challenged by the Paris Climate Agreement decision to move away from coal. In the wake of this treaty countries like China and Japan have refocused their efforts in developing renewable energy and this has negatively hampered Botswana’s economic ambitions.
