Assessment of the Need for the proposed Karpowership Power Plant projects
The report argues that the proposed 1.2 GW Karpowership gas power plants are not aligned with a least-cost investment pathway for South Africa. Drawing on a study by Meridian Economics and the CSIR, it finds that the grid should prioritize rapid renewable energy build-out and storage, with new gas capacity not being economically optimal until the mid-2030s. The document concludes that commissioning these plants by 2022 would create an unnecessary economic burden for ratepayers and that the procurement process (RMIPP) was biased against renewable energy options.

CRITICAL MINERALS AND METALS STRATEGY SOUTH AFRICA
South Africa's Critical Minerals and Metals Strategy aims to maximise the economic value of its vast mineral reserves—including PGMs, manganese, and vanadium—by shifting from raw ore exports to local beneficiation and high-tech manufacturing. The strategy identifies a specific list of high, moderate-to-high, and moderate criticality minerals and proposes six pillars of intervention: geoscience mapping, value addition, R&D, infrastructure/energy security, financial instruments, and regulatory harmonisation. It emphasizes the need to overcome domestic bottlenecks in energy and logistics, foster regional integration within Africa, and navigate geopolitical tensions, particularly China's dominance in the supply chain, to secure a role in the global green energy transition.

TURN ON THE FLOODLIGHTS: TRENDS IN DISCLOSURE OF ENVIRONMENTAL LICENCES AND COMPLIANCE DATA
The report finds that South African environmental laws generally lack mandatory disclosure requirements for licences and compliance data, relying instead on the Promotion of Access to Information Act (PAIA). This contrasts with jurisdictions like Australia and Canada, where public registries are more common. Analysis of multinational companies shows they typically disclose information only where legally required. The report recommends making disclosure mandatory for all licence holders and establishing central online public registries.

TRANSWORLD ENERGY AND MINERALS RESOURCES - XOLOBENI
The AmaDiba Crisis Committee (ACC) successfully appealed a mining right granted to Transworld Energy and Minerals Resources (TEM) for titanium-bearing minerals in the Xolobeni area. While the Minister of Mineral Resources withdrew the right on 6 June 2011 due to outstanding environmental issues, the decision is considered interim as TEM may still address these concerns. The ACC's appeal highlighted several critical failures, including the location of the project within a Marine Protected Area, the lack of a community resolution, and a flawed public consultation process. The three-year delay in the Minister's decision caused significant prejudice to the community, hindering an existing eco-tourism project and creating internal social conflict.

榨乾榨淨
The report examines over 400 products from Nestlé, Danone, Mead Johnson, and Abbott across 14 countries. It finds that while basic nutritional components generally meet international standards, the proliferation of different product lines—including 'premium' versions and age-specific formulas—is a sales strategy to increase market share and bypass marketing regulations rather than a result of scientific advancement. This is particularly evident in high-growth Asian markets where 'premium' products are priced significantly higher than basic options, sometimes costing parents a substantial portion of their monthly income. The document calls for stricter government oversight and adherence to WHO marketing guidelines.
