Desmond Barry, Founder and Consultant at ESG Lead
At a recent ESG Lead webinar, New Tides in Sustainable Investing: the Bigger Picture, four important trends in ESG and sustainable investing were identified. These are not necessarily the headlines that dominate public debate but are deeper shifts beneath the surface — long-term movements that continue despite political backlash, energy insecurity, and anti-ESG sentiment.
Taken together, they suggest something important: that the underlying institutions and principles of ESG and sustainable finance remain resilient, and continue to adapt and strengthen. For fiduciary investors, that provides both reassurance and direction.
Value creation and financial materiality.
The first current is the continuing emphasis on value creation and financial materiality.
ESG is increasingly moving away from being presented primarily as a moral overlay or a reputational or compliance exercise. Instead, sustainability considerations are becoming embedded in the core drivers of business performance — strategy, operations, governance, and capital allocation.
At company level, firms increasingly recognise that issues such as energy efficiency, resource use, supply-chain resilience, workforce stability, and governance quality are not peripheral concerns. They are closely tied to competitiveness and long-term performance.
Climate risk, in particular, is now being integrated more systematically into governance and investment decision-making, supported by disclosure frameworks such as those developed through the International Sustainability Standards Board.
Investors have also become more focused and more demanding. ESG analysis is increasingly embedded into mainstream investment processes — portfolio construction, scenario analysis, and capital allocation — rather than treated as a separate compliance exercise.
The strongest advances are occurring where sustainability is linked directly to the drivers of financial performance.
This shift has also been reinforced by changing economics. Renewable energy technologies have become dramatically cheaper over the past decade, in many cases reaching cost parity or outperforming traditional alternatives. Markets themselves are increasingly reinforcing the transition.
At the same time, investors are assessing emerging areas such as green hydrogen, advanced battery systems, and carbon capture technologies for their long-term strategic value.
The result is a more disciplined and credible model of ESG — one shaped partly by earlier criticisms around greenwashing, weak data, and exaggerated claims. Excess is being trimmed away. Increasingly, the ESG and sustainability disciplines must demonstrate their contribution to resilience, competitiveness, and long-term returns.
Recognising transition and transitional realism.
There is now broad recognition that the global economy is moving through a climate and energy transition and there is a change in the way that transition is being approached. This is the second current.
Rather than relying primarily on exclusion or divestment, investors are increasingly focused on how high-carbon sectors transition. The emphasis is shifting towards engagement, innovation, and capital allocation that supports credible pathways to adaptation and decarbonisation.
This is the logic behind transition finance.
Capital is flowing not only towards fully green assets, but also towards bridging technologies, industrial transformation, and efficiency improvements that help move existing systems towards lower emissions over time.
The underlying reality is straightforward: the global economy cannot decarbonise overnight. Heavy industry, infrastructure, and energy systems require time, capital, and technological evolution.
At the same time, the transition itself is creating major investment opportunities. Renewable energy, electrification, sustainable infrastructure, and new financing instruments are becoming important drivers of growth and capital deployment.
Green bonds, transition bonds, and blended finance structures are expanding rapidly, particularly in emerging markets where public and private capital increasingly work together to mobilise investment and manage risk.
Yet major gaps remain. Capital flows remain wholly insufficient relative to the scale of the challenge, especially across much of the Global South.
Expanded reporting and standardisation.
Sustainability reporting has often been criticised for inconsistency, complexity, and weak comparability. Concerns around greenwashing have intensified demands for more rigorous and decision-useful information.
In response, global reporting frameworks continue to converge, particularly through the work of the International Sustainability Standards Board, alongside developments in the European Union and evolving disclosure requirements in other jurisdictions.
This is the third current and the direction of travel is towards a more consistent global baseline.
Equally important is the shift away from disclosure volume towards decision-useful data — information that can be linked directly to financial performance, valuation, and risk assessment.
There is also growing emphasis on measurable outcomes. Sustainability-linked bonds and loans increasingly tie financing terms directly to specific environmental or social targets, supported by more precise and auditable performance indicators.
In effect, sustainability is gradually being translated into quantifiable metrics with direct financial consequences.
That strengthens accountability, reduces the scope for greenwashing, and aligns sustainability objectives more closely with the incentives driving corporate behaviour and capital allocation.
Growing recognition of system-level risk.
The fourth trend takes the discussion beyond individual companies and sectors to the functioning of economies and societies as a whole.
Climate change is the most visible example, but it is not the only one. Biodiversity loss, water scarcity, resource constraints, inequality, unemployment, and economic instability are increasingly recognised as financially material risks capable of affecting entire markets and economies over time.
These are system-risks which cannot simply be diversified away.
At the same time, the global conversation itself is changing. The sustainability agenda is no longer shaped solely by developed markets. Perspectives from the Global South are becoming increasingly influential, reframing ESG in terms of development, resilience, inclusion, and economic participation.
There is also growing attention to biodiversity and natural systems as foundational components of economic stability.
For countries such as South Africa, sustainability cannot be separated from issues such as infrastructure development, unemployment, energy security, and long-term economic growth.
Balancing environmental objectives with development priorities is not always straightforward. But mechanisms such as transition finance and blended finance increasingly provide ways of supporting both decarbonisation and broader economic development.
For fiduciary investors, the implications are significant.
Managing system-level risk is not simply about protecting portfolios from downside exposure. It is also about positioning portfolios to benefit from the structural transformations now underway across energy systems, infrastructure, technology, and sustainability-linked markets.
Taken together, these four tides — financial materiality, transitional realism, improved reporting, and system-level risk awareness — point in the same direction.
They suggest that sustainable investing is becoming more practical, more measurable, and more closely aligned with long-term fiduciary responsibility.
And ultimately, that is what gives it durability beyond the current cycle of uncertainty.
Ed’s note: ASSA’s Climate Index measures how often and how severely extreme weather events occur in South Africa, so that actuaries, insurers and policymakers can better understand and manage climate risk over time. EBnet’s podcast series, Heatwave Horizons, chats to experts in their fields on what this means for sustainability.
