Sustainable Aviation Fuels (SAFs) are considered one of the potential ways for airlines to reduce emissions. However, African airlines may need more support using SAFs in underdeveloped regions. This paper calculates the carbon emissions from the international routes in Africa from 2019 to 2021 through the Modified Fuel Percentage Method (MFPM) and the ICAO standard method. The error rate is about 4.10%. Then, we predict the carbon emissions for each route and airline under different epidemic recovery paths and analyze the potential subsidies, the impact of SAFs price adjustment, and carbon trading price changes. It can be found that the more extensive the overall carbon emission base, the higher the cost of using SAFs. In addition, the higher the SAFs mixing ratio, the more the cost will increase. The average subsidy to promote SAFs will be 3492.82–3784.74 million dollars at a 50% mixed ratio. By 2025, if only the carbon price is not lower than 12.84 times the current price, or the SAF price is 1.412 times lower than the current aviation kerosene price, the African airlines may promote the SAFs. • Cost-benefit analysis of Sustainable Aviation Fuels (SAFs) in Africa aviation industry is done. • The average subsidy to promote SAFs will be 3492.82–3784.74 million dollars at a 50% mixed ratio. • Only the carbon price is not lower than 12.84 times, or the SAF price is 1.412 times lower, the African airlines may promote the SAFs.

Introduction Burn and ingestion injuries are common in developing countries because of poor access to safe energy sources, crowded living conditions, and insufficient knowledge of potential risks. The purpose of this study is to understand the scope of burn and ingestion injuries due to various energy source usages in South Africa. Methods Patients at 16 regional hospitals throughout South Africa presenting with an energy-related injury between 2006 and 2012 were interviewed to obtain demographics and injury characteristics. Results A total of 12,443 patients were included in this study. Children aged 1-2 years predominantly experienced burn and ingestion injuries (21%). Liquid burns (30%) were more common than flame burns (14%). Chi-squared tests show that age was significantly related to degree of burn, type of burn, and severity of burn (p<0.001). Non-intentional injuries (45%) were more frequent than self-inflicted or assault injuries. Temporal and seasonal injury trends reflect usage patterns. Burn injuries result in longer hospital length of stay than ingestion injuries. Conclusion Non-intentional liquid burns and ingestions to infants and babies were most common in this study, with many injuries also occurring among young adults. It is advised that interventions targeting low-income communities be conducted to increase awareness of burn and ingestion injuries. [ABSTRACT FROM AUTHOR]

Paraffin (called kerosene in North America and other parts of the world) is the most commonly used fuel in ‎non-electrified dwellings worldwide. It is especially popular in Africa and South Asia. Although paraffin ‎offers many advantages-especially its comparatively low cost to produce-it poses two major risks of ‎injury. First, paraffin poisoning is common, either through ingestion or through inhalation of smoke and ‎fumes. Second, paraffin is highly flammable, and poses fire risk through multiple causes. This commentary ‎discusses strategies to prevent paraffin-related injury. Prevention of paraffin-related injury must be through ‎multiple strategies, and should include policy-oriented change, changes to the safety of home environments, ‎and behavioral changes targeting how individuals store and use paraffin and paraffin appliances. We review ‎successful prevention strategies in each of these domains and discuss appropriate research and community ‎initiatives that should be implemented to improve paraffin safety among at-risk populations. ‎
