Board accountability is outrunning capability

Climate Week NYC is one of the world’s most significant annual gatherings focused on climate, nature and sustainability. Timed to coincide with the annual United Nations General Assembly (UNGA) in New York, it brings together business leaders, investors, policymakers, civil society organisations and innovators to showcase action, debate emerging challenges and accelerate solutions. It also offers a useful indication of how climate and nature policy, investment and business thinking are changing.

The 2026 edition of Climate Week NYC included more than 1,000 independent events ranging from multi-day conferences to small roundtable kōrero. The tone was more restrained, with optimism tempered by a more complex reality – one in which the transition to a low-emissions, nature-positive economy remains essential, but the pathway is becoming less certain, more contested and more exposed to geopolitical disruption.

Sustainability has become a strategic resilience challenge involving risk, capital allocation, technology, supply chains, policy uncertainty and long-term value creation.

Uncertainty came up repeatedly, but not as a reason to delay action. It is why boards must strengthen their oversight capabilities and focus on building organisational resilience.

The growing gap between accountability and capability

At a board leadership roundtable convened by the Chapter Zero Alliance and the UN Sustainable Stock Exchanges Initiative (UN SSE), participants highlighted a widening gap between what boards are accountable for and what many boards are equipped to govern.  

Directors across the world are expected to oversee interconnected climate, nature, energy, geopolitical and physical risks. Yet many boards were established in a period when these issues were viewed as externalities rather than fundamental strategic considerations.  

Directors need the ability to challenge assumptions, interrogate transition plans, understand systemic dependencies and test the resilience of business models under different future scenarios. Scenario planning, assumption testing and adaptive strategy are becoming core board competencies rather than specialist sustainability activities.

New Zealand organisations face growing exposure to climate impacts, biodiversity loss, global market shifts and changing policy settings. Boards will not necessarily be able to predict what comes next, but they can prepare for more than one possible future.

Nature has moved into the mainstream

Only a few years ago, biodiversity and ecosystem resilience were on the margins of sustainability conversations. Today, they are much more central to discussions about business continuity, supply chain resilience, insurance availability and economic stability.

Across multiple events there was recognition that climate and nature should not be treated separately. Businesses depend on ecosystem services ranging from water security and healthy soils to pollination, flood management and stable weather systems. As these systems continue to degrade, operational and financial risks increase.

Forward-looking organisations are beginning to identify opportunities associated with restoration, natural capital, regenerative business models and nature-positive investment.  

Boards need to consider nature-related risks and opportunities within mainstream governance processes rather than treating nature as a separate sustainability workstream. 

Credibility matters more than commitments

Investors, regulators and stakeholders are becoming less interested in long-term commitments alone and more focused on evidence of delivery. Ambitious targets remain important, but they must be accompanied by realistic implementation plans, investment decisions and measurable progress.

The Chapter Zero Alliance/UN SSE roundtable highlighted the importance of aligning sustainability disclosures with capital allocation decisions. Investors want reassurance that sustainability commitments are embedded in operating models, investment priorities and long-term business strategy rather than existing as standalone, short-term promises.

Targets carry little weight if resources, incentives and strategic decisions are not aligned with achieving them.

Boards therefore need to test whether investment decisions, mergers and acquisitions, executive remuneration and strategic planning are consistent with those commitments. 

AI is raising the bar for transparency

AI also featured in discussions about sustainability governance.

AI offers opportunities in data collection, analysis and decision-making, but it will also make inconsistencies easier to detect. Improved analytical capability means that gaps between commitments, disclosures and real-world performance will become more visible.

At the Chapter Zero Alliance/UN SSE roundtable, participants said boards need to focus on identifying the metrics that genuinely inform decision-making and ensuring these are communicated clearly through reporting and disclosure processes. AI-enabled scrutiny will make it easier for investors and stakeholders to identify gaps between ambition and execution.  

Resilience as the boardroom agenda

Resilience ran through discussions on climate, nature, sustainability and governance.

It encompasses the capacity of organisations to absorb shocks, adapt to changing conditions and continue creating value amid disruption. It requires boards to think across time horizons, challenge management assumptions and govern for uncertainty rather than stability.

Directors face a difficult environment. Geopolitical tensions, policy volatility, physical climate impacts, nature degradation, technological disruption and shifting stakeholder expectations are adding to the uncertainty boards must govern through.  

The organisations better placed to succeed over the coming decade are likely to be those whose boards look beyond quarterly performance to understand the longer-term drivers of resilience, competitiveness and value creation.

Climate and nature are now part of a much wider resilience challenge. Boards that can test assumptions, prepare for different futures and connect sustainability commitments to investment and strategy will be better placed to navigate that uncertainty.
