Stewardship, sustainable business and responsible trade: Climate, circularity, ESG and human flourishing

Sustainability becomes a business discipline when claims about climate, resources, people and trade are translated into testable responsibilities, measurable impacts and defensible choices. This chapter treats sustainable business as a strategic, scientific, moral and cross-border problem rather than as an ESG scorecard. It develops competing theories of sustainability; trade-growth-environment relationships; financial, impact and moral materiality; climate and nature risk; responsible sourcing and human-rights due diligence; circular economy and life-cycle reasoning; greenhouse-gas accounting, targets, carbon pricing and border measures; reporting, assurance and greenwashing controls; and the links to sustainable finance and procurement. Sasol anchors the African analysis, illustrating the tensions among industrial production, emissions, energy security, jobs, technology and offsets, while Maersk provides a global comparison of efficiency gains and rising absolute emissions. African energy access, AfCFTA, green industrialization and policy sovereignty are treated as central development questions. Christian moral reasoning frames creation care as stewardship ordered to truth, neighbour-love, justice, responsible freedom and human flourishing.
