The birth of the Chief Sustainability Officer role
The origins of the CSO role go back to the early 2000s — driven by growing environmental concerns and the recognition that sustainability is a business imperative. In the early days, CSOs were often limited to environmental compliance and corporate social responsibility programmes. But the scope expanded quickly once the tight link between sustainable practices and long-term corporate resilience became visible.
The growing horizon of CSO responsibility
Today, the CSO’s remit reaches far beyond the original tasks. Modern CSOs connect sustainability goals to the overall strategy — and create alignment that supports both environmental responsibility and corporate growth. A quiet but important ally in this: the growing range of carbon-management tools that enable precise capture, analysis and reporting of emissions and other environmental metrics.
Within the corporate environment, CSOs have taken on a leadership role on sustainability. A prime example is Apple Inc., where Lisa Jackson, as Chief Sustainability Officer, drives the company’s climate initiatives — particularly in renewables and energy efficiency (1). Under her leadership, Apple has set the ambitious goal of becoming carbon-neutral across its entire business model and product life cycle by 2030.
Challenges and opportunities for CSOs today
The path to sustainability is paved with challenges — from resistance to change, through budget constraints, to shifting regulation. But it’s exactly those hurdles that open up space for innovation. Carbon-management tools like today.green not only help with compliance but also surface opportunities for cost savings and efficiency gains.
The evolution of the CSO role shows a clear upward trajectory — in parallel with the growing importance of sustainability. In 2018 eight US-listed companies appointed their first CSO; by 2022 the number was over 40. In 2020 and 2021 almost as many CSOs were appointed as in the eight years before combined — a clear sign of the growing role of sustainability in day-to-day business (2). With the rise of the circular economy, climate-risk assessment and stricter ESG reporting, the role of CSOs will keep gaining weight.
The rise of CSOs is also visible in numbers. A report by Weinreb Group shows a clear increase: over 40 US-listed companies appointed their first CSO in 2022 — a significant jump from eight in 2018. A survey also finds that three quarters of US CSOs are now part of their company’s executive leadership team — evidence of their growing authority and influence (2).
Bottom line
The story of CSOs is one of evolution, challenge and opportunity. As the pivot of corporate sustainability, their role is indispensable in steering companies into a sustainable and resilient future. The inspiring careers of CSOs like Lisa Jackson at Apple show the deep impact — and the enormous possibilities — that lie in corporate sustainability.
