This present study develops and applies an integration of environmental costs within the financial reporting perspective through the lens of sustainability cost accounting on issues of measurement and reporting of broad corporate sustainability, drawing widely from sources such as peer-reviewed academic journals, industry reports, and policy documents from authoritative bodies that have applied a systematic search strategy with selective inclusion criteria; this considers literature spanning 2013 to 2023. Key issues emerging from this qualitative content analysis are environmental cost measurement, corporate-level reporting on sustainability, and integrating environmental costs into financial decision-making. The results provide a rationale for the importance of sustainable cost accounting in ensuring corporate transparency, regulatory compliance, risk management, and operational efficiency. The key issues this paper identified were poorly developed structures for the measurement of environmental costs, besides problems with data capture and high costs of implementation.Despite these, this study demonstrates how businesses can competitively benefit by incorporating environmental costs into their decision-making strategies in order to enhance the levels of sustainability and investment potential at low environmental and financial vulnerabilities. It concludes, in particular, that sustainable cost accounting will be furthered in the future by better regulatory regimes combined with a deeper corporate will for ecological stewardship toward long-term financial security and a more sustainable world economy.
