“…In addition, the Paris Agreement that was adopted in 2015 committed countries to a global goal to reduce carbon emissions based on what each considered fair and ambitious. According to Feig, Joubert, Mudau, and Monteiro (2017), 40 per cent of anthropogenic emissions has been trapped in the atmosphere since 1750, while the rest has been removed by ocean and vegetation sinks. South Africa is the 13 th largest carbon emitter in the world and the largest in Africa with an estimated 8.9 tonnes per capita.…”

This study seeks to establish the relationship between carbon emissions, agricultural output and industrial output in South Africa. It uses data from 1960 to 2017 based on an annual frequency, giving a total of 58 annual observations. The Autoregressive Distributed Lag technique is employed to estimate the model on a bivariate basis. The evidence shows that carbon emissions are not influenced by agricultural and industrial output. Conversely, agricultural output is influenced by carbon emissions and industrial output. The results suggest that climate change resulting from carbon emissions has led to reduced agricultural output, adversely affecting food security. The significant relationship between industrial and agricultural output suggests that a properly functioning industrial sector will cause an increase in the agricultural output. The study’s findings have implications for climate change and manufacturing policies in South Africa.

“…There is a general country-wide lack of information regarding CO 2 atmospheric loading. However, efforts are made to close this gap, two new ambient CO 2 stations are commissioned in the northeast of the country (Feig et al, 2017). The two new stations are also aimed at reducing the high uncertainty associated with CO 2 emission flux estimation over the country, from CO 2 measurements from the Cape Point GAW station and inverse modelling (Feig et al, 2017;Nickless et al, 2015).…”

South Africa is the dominant continental source region of CO 2 fossil fuel emissions. This is a result of the strong dependence of its economy on fossil fuels. However, the observations of atmospheric CO 2 in South Africa are inadequate. The country has the Global Atmospheric Watch (GAW) Cape Point station as the only site with long-term ambient CO 2 monitoring record. In this study, satellite data retrieved from the Tropospheric Emission Spectrometer (TES) instrument on board the Aura satellite from Dec 2004 to Dec 2009 is used for the first time to quantify the spatial distribution of CO 2 over South Africa, as well as to determine its annual variability at selected sites. The study found that the surface CO 2 foot print in South Africa resembles the industrial CO 2 emission sources spatial distribution, particularly during the summer and autumn. In winter and spring seasons the surface CO 2 foot prints are spatially expanded as a result of contributions of emissions from biomass and domestic fossil fuel combustion. The surface levels of CO 2 at the study areas have been increasing during the period of the analysis.

“…11−13 Reducing the emissions generated from improper management of waste by capturing the CO 2 would help in further meeting the Paris Agreement Pledge made at the 2015 Climate Change Conference. 14 Carbon capture and storage (CCS) technology is an innovative technology used in reducing CO 2 emissions into the atmosphere. This involves capturing CO 2 from large stationary sources, such as fossil-fuelled power plants, cement, and steel industry, transporting of CO 2 into storage sites, and injecting into underground storage.…”

“…Improper management of waste can lead to the spread of pathogens, water contamination, and soil and air pollution. − An effective waste management system must be environmentally sustainable, viable, and generally acceptable . Waste to energy is one possible solution in managing MSW disposal due to its ability to generate energy while also reducing the volume of MSW. − Reducing the emissions generated from improper management of waste by capturing the CO 2 would help in further meeting the Paris Agreement Pledge made at the 2015 Climate Change Conference …”

Chemical looping combustion (CLC) is a novel carbon capture and storage technology that can be used in the proper disposal of municipal solid waste when used as a solid fuel. In this study, the results of the CLC of paper, plastics, and paper/plastic blends were compared with CLC of South African coal using Chemcad software. The simulation was done for two different CLC processes, namely, chemical looping oxygen uncoupling (CLOU) and in situ gasification CLC (IG-CLC). The results demonstrated that coal at 66% had a lower CO 2 yield than paper (86%) but a higher yield than all the plastic samples in CLOU (3356%) and an equal CO 2 yield in paper and all plastic samples in IG-CLC. Furthermore, coal had a lower CO 2 gas yield than all the optimum blends (72–85%) for CLOU and an equal yield with the entire paper/plastic blend in IG-CLC. On combustion efficiency, coal has a lower combustion efficiency at 80% than paper and polyvinyl chloride (PVC) at 90 and 96%, respectively, but a higher efficiency than other plastic samples that are between 30 and 70% in CLOU while in IG-CLC, it had a lower efficiency than paper, PVC, and polyethylene terephthalate and higher efficiency than high-density polyethylene, low-density polyethylene, polypropylene, and polystyrene. For paper/plastic blends, coal has higher combustion efficiency than all the paper/plastic blends in both CLOU and IG-CLC processes except for the paper/PVC where the combustion efficiency was higher than coal.
