In a world of trade tariffs, geopolitical tension and shifting regulation, some businesses have quietly stepped back from their sustainability commitments by deprioritising net zero targets, scaling back ESG programmes, and waiting for things to change. The accountancy body says this may be the most expensive mistake they make.

That was the central message from ACCA’s annual Sustainability Conference, held on Earth Day, a virtual event attended by finance professionals from over 100 countries. The argument put forward was not a moral one. It was a financial one: organisations that fail to embed sustainability into their core strategy are accumulating risk, and in many cases, that risk is already materialising.

“Your sustainability strategy is not something that sits on the side,” said Sharon Machado, head of sustainable business at ACCA, who chaired the opening session. “It’s integrated within the business. It’s about risk management.”

“When businesses think about geopolitical disruption, supply chain fragility, commodity availability or the impact of extreme weather on operations, they are, whether they recognise it or not, thinking about sustainability. The language of risk management and the language of sustainable business describe the same terrain,” she said.

Risk, finance and sustainability leader, Andrea Amaize, who joined Ms Machado for the session, put it directly: “Though the business case for sustainability remains strong today, organisations that have toned down or deprioritised their sustainability commitments are trying to balance long-term sustainability objectives against pressures for near-term results.”

However, immediate impacts of sustainability are being felt. Climate change is already affecting the availability and cost of insurance, purchasing decisions increasingly include questions about decarbonisation strategies, access to lower cost capital is becoming tied to sustainability performance and talent follows purpose.

A core argument of the session was that sustainability, properly understood, is not only a cost driver but also a profitability generator – unlocking new revenue streams, reducing operating costs, improving resilience, strengthening brand value and creating competitive advantage.

Ms Amaize noted that, in today’s environment, it is important for organisations to clearly demonstrate how sustainability drives measurable financial outcomes, an area where finance professionals can play a pivotal role in evidencing this link.
