Though ESG can be traced back to earlier periods, when it was mostly about ethical investing, like saying no to tobacco, weapons, or anything that seemed or felt morally questionable, its official presence began in 2004, with the UN report "Who Cares Wins", which first popularised the term ESG, which then became mainstream from 2010 to 2020. Now, ESG frameworks actively scrutinise companies' products and their broader impact on people and the planet. Over the years, ESG standards and certifications have helped drive a shift from ethical investing to values, and then to the drivers of values, among all stakeholders. ESG is an evolution of management thinking, not a passing cloud.
Fundamentally, ESG has three areas: environmental (emissions, resource use and climate risk); social (labour, supply chains, community impact and human rights); and governance (board structure, CEO compensation, audit quality and shareholder rights). Some corporate illustrations reflect the changing narrative; nearly four-fifths of Unilever's major agricultural products are now sourced sustainably and the company is making quantifiable progress towards its net-zero and nature-positive 2039 goals.
Patagonia has started sharing comprehensive climate-risk and emissions data, including the water and chemical footprints of its textile operations, in an effort to continue referring to itself as "carbon neutral" and its most recent climate targets centre on net-zero by 2040 and science-based reductions through 2030.
ESG has now created a second-order system of rules, data, governance and greenwashing dynamics that exposes less-prepared firms to ESG disclosure through evidence-based metrics, audit trails and external assurance.
ESG stance has grown from a voluntary narrative to a regulated information system. Today, emissions make up 88% of the total business emissions, but still, firms lack a robust reduction target, which is a major blind spot for organisations.
Corporate emissions are classified into three "scopes" in climate reporting: Scope 1: direct emissions from a company's own operations, such as its factories, offices and company vehicles; Scope 2: indirect emissions from the electricity and heat it purchases; and Scope 3: all other emissions in the value chain, including transportation, customer use of the product, end-of-life disposal and emissions embedded in purchased raw materials and supplier activities.
Scope 3 emissions account for the majority of a company’s carbon footprint but are poorly managed and quantified, making this the largest blind spot.
When investors and regulators rely on this data, inaccurate and inconsistent Scope 3 reporting becomes a systemic threat.
Simultaneously, greenwashing has progressed beyond straightforward marketing spin to encompass net-zero planning. Newer analytical work is beginning to quantify this risk, demonstrating that lobbying against aggressive climate policy frequently correlates with inadequate transition plans and that the exclusion of Scope 3 and excessive dependence on low-quality offsets are reliable red flags.
ESG is now acting as a gatekeeper for credit, not just equity capital. As banks and lenders in key markets increasingly incorporate ESG profiles into credit evaluations, companies with weaker ESG data and governance will face higher borrowing costs.
Lastly, the political pushback against ESG is not the end of the story; rather, it is part of its progress. While some governments are strengthening disclosure requirements and stepping up enforcement against greenwashing, others are restricting the vocabulary and instruments of ESG.
ESG is moving from a corporate trend to a more permanent, albeit contentious, aspect of how markets function as a result of this tug-of-war, driving it out of soft, values-based arguments and into the more difficult areas of regulation, litigation and fiduciary obligation.
Though it began as an investor perspective, finance-enforced, it will influence how businesses operate and how stakeholders and corporate ecosystems make their choices. In the future, ESG will be part of the core reporting infrastructure. Companies will be required to integrate ESG into strategy, supply chains, product design and HR.
ESG will influence valuations, loan pricing and access to capital on a scale. The world can expect more scrutiny and polarisation, creating a more complex, uneven global ESG landscape.
