    (Energy Systems Research Group, 2025-08-27) Marquard, Andrew; McCall, Bryce; Caetano, Tara; Burton, Jesse; Stevens, Luanne; Ireland, Gregory; Keen, Samantha; Winkler, Harald; Merven, Bruno; Tatham, Julia; Cunliffe, Guy; von Blottnitz, Harro; Jooste Upadhyaya, Meagan; Nosrati-Ghods, Nosaibeh; Gogela, Usisipho; de Kock, Savanha; Hughes, Alison; Gabin, Matthew; Masenda, Joseph
    This technical analysis has the primary objective of supporting the Department of Forestry, Fisheries and the Environment (DFFE) in its development of the mitigation component of South Africa’s second NDC. The mitigation analysis is part of a broader set of analyses to support the NDC, including work on adaptation and loss and damage (undertaken by the African Climate and Development Initiative (ACDI)) at the University of Cape Town (UCT), and work on support requirements / provision by SouthSouthNorth (SSN). The analysis has been primarily undertaken by the Energy Systems Research Group (ESRG) at UCT, with contributions from PRISM at UCT, the CSIR, and CRSES at the University of Stellenbosch. The goal of the analysis is to assess the following: South Africa’s international obligations with regard to the Paris Agreement; An assessment of what national mitigation contribution up to 2035 would constitute South Africa’s “fair share”; An assessment of the GHG emissions implications in 2035 of current mitigation and/or mitigation policies and plans; An assessment of what additional measures would be required to achieve additional mitigation outcomes in 2035; Additional analysis of the implementation requirements and just transition requirements for a representative GHG emissions outcome in 2035; Additional analysis on the impact of specific GHG emissions pathways on local air pollution; and Additional assessment of the reliability and GHG emissions outcome of electricity systems modelled in SATIMGE for specific GHG outcomes using other modelling frameworks; These are DRAFT results.

    The impact of solid cooking fuels on the health of rural South African households
    (2021) Tatham, Julia; Muchapondwa, Edwin
    Indoor Air Pollution (IAP) from the combustion of solid cooking fuels has been proven to adversely affect the health of household residents. Those most affected by IAP are the poorest and most vulnerable members of society, specifically poor women and children residing in rural households. This study evaluates the impact of using solid cooking fuels on various health outcomes of residents in rural South Africa, using the nationally representative General Household Survey 2018. Propensity Score Matching Methods are used to address the confounding of variables associated with the use of solid cooking fuels and health outcomes. We find that the use of solid fuels significantly increases the risk of suffering from Acute Respiratory Illnesses (ARI's) as well as increasing the risk of residents reporting a poor health status. Our analysis goes on to evaluate separate gender and age groups and find some evidence that women and the elderly may suffer relatively more adverse health outcomes from the use of solid cooking fuels. Our results suggest that IAP from the combustion of solid fuels poses a threat to health of South Africans residing in rural households. Hence policy should focus on providing access to clean sources of energy for cooking in rural areas.
