The transportation and logistics sector contributes substantially to global carbon dioxide emissions, accounting for roughly a quarter of the total. This figure is predicted to increase in the years ahead. Notably, air freight emerges as the most significant contributor, emitting an average of 500g of carbon dioxide per tonne and kilometre travelled.
Conversely, road freight emissions range from 60g to 150g per tonne and kilometre travelled, while rail transport presents a more eco-friendly option with emissions ranging from 30g to 100g. Additionally, container ships demonstrate the lowest pollution levels, emitting only 10g to 40g per tonne and kilometre. However, when factoring in the electrification of the rail system, rail transport’s emissions can potentially reach zero.
Amid this context, a crucial inquiry arises: Is the future of sustainable transportation rooted in railways? This question gains prominence as the world faces the imminent challenge of petroleum scarcity within the next three decades. With the global community grappling with an escalating climate crisis and dwindling petroleum reserves, electric railways emerge as a viable solution for passenger and freight transportation.
Noteworthy players in this movement are countries such as the US, China, Russia, and the EU. These nations, whether advanced or emerging economies are significantly investing in bolstering their railway networks. These endeavours often accompany transformative master plans, reflecting a commitment to securing a sustainable future.
However, the preparedness of state-owned rail operators to navigate this transition remains a vital consideration. Inadequate preparation for transitioning from internal combustion engines to renewable energy sources could potentially jeopardize a nation’s energy security strategy.
In the context of South Africa, where the railway system is the most advanced on the African continent, with an extensive network spanning 30,000km of track, several challenges warrant attention. The passenger rail operator, Prasa, grapples with the daunting task of curbing vandalism and theft, issues that exacerbate operational complexities and financial losses. This year, an estimated loss of R1.7 billion is projected. Suspicions also suggest that vested interests, including the competitive taxi industry, might be involved in acts of vandalism to secure a larger market share of commuters. Unfortunately, investigations have yielded minimal meaningful convictions, perpetuating the problem.
To address these challenges, the transport ministry is actively crafting comprehensive security strategies that encompass both law enforcement and in-house security measures, aimed at countering property theft and damage. Prasa’s passenger trains have also gained notoriety for their delays and inefficiencies. Rectifying this situation is paramount, as trains serve as an affordable transportation option for numerous low-income households. Addressing inefficiencies and ensuring dependable services could play a pivotal role in alleviating socioeconomic inequalities—challenges that are more pronounced in South Africa than in many other parts of the world.
In conclusion, the transportation landscape is gravitating toward railways as the world addresses carbon emissions and anticipates petroleum scarcity. State-owned rail operators, such as Prasa and Transnet, must be poised to transition toward renewable energy sources. Addressing challenges like vandalism, theft, and inefficiencies will be instrumental in securing a sustainable and equitable future for South Africa’s transportation system….
