NY Climate Week: could a change be brewing in corporate sustainability?

I went to New York for Climate Week.

Climate Week sometimes gets criticised as people preaching to the converted. I understand where that view comes from. There are plenty of panels, receptions and polished statements. But for me, Climate Week's real value is as a temperature check. What are NGOs pushing on? What are investors asking? What are companies struggling with? What is real, and what is mostly noise?

This year, one message stood out. Sustainability has not disappeared, but the way businesses discuss it is changing. It is becoming less of a separate ESG agenda and more closely integrated into conversations about risk, opportunity, competitiveness, flexibility and the ability to adapt.

That does not necessarily represent a retreat from sustainability. It may actually be a sign of maturity. Climate, water, energy, agriculture and supply-chain issues are moving closer to the operational and investment decisions that determine whether a business is prepared for a more volatile world.

You can read reports and join webinars, and I do plenty of both. But sometimes you get a better sense of where things are moving by speaking to people directly.

That is what I found useful in New York.

The week started on Sunday evening with Copenhagen Infrastructure Partners and a group of investors, industry leaders, public-sector representatives and partners discussing the next phase of global energy infrastructure.

It was encouraging to hear how the Philippines has opened renewable energy projects to 100% foreign ownership, helping attract more international capital and expertise to improve the country's energy infrastructure.

Grid capacity, flexibility and batteries were among the most discussed topics. The point was not simply that renewable power reduces emissions. On-site solar, storage and hybrid renewable systems can also reduce exposure to fossil-fuel shocks, grid constraints and price volatility.

That changes the business case. As batteries improve and renewable systems become more integrated, clean energy increasingly looks like a way to increase operational flexibility and hedge against disruption, not only as a climate investment.

I also valued the Danish angle. Conversations with Danish companies, the Consulate General of Denmark in New York, Danish Industry and the Danish Chamber of Commerce were a useful reminder that small countries and internationally oriented companies can still contribute quite practically to the discussion. This is particularly true when the focus is on solutions, partnerships and implementation rather than slogans.

And it is always a pleasure to get a pep talk from Paul Polman. His message was a useful reminder that valuing the planet has to be part of the business process itself, not something added afterwards. We still have choices to make, but the window is narrowing.

This connection between sustainability and business resilience came through in several discussions. Many companies are already looking at familiar levers such as insurance, property protection, supply-chain diversification and business continuity planning. Those things matter. But they can also create a false sense of comfort if they make us overlook the bigger, indirect or longer-term impacts of climate change.

The more interesting question is not only how we protect what we already have. It is how resilience can help shape better decisions, better investments and, in some cases, create business advantage.

One analogy from the week captured this well.

Business as usual is like building a car to drive 300 kilometres per hour in a straight line on a perfect road. But that is not the road businesses are actually on. Climate change and increasingly erratic weather mean more turns, rougher surfaces and unexpected obstacles.

We need a different car: better traction, a different engine, proper cooling and the ability to respond quickly when conditions change. In other words, businesses need to be more flexible and adaptable. Anything else is simply bad business.

The same theme came through in conversations about farming and food systems. Farmers are not an abstract part of a supply chain. They are people managing changing weather, water availability, yields, crop quality and livelihoods, while testing what climate-smart innovation looks like in practice.

Regenerative agriculture can help make farming systems more resilient. But it also exposes a difficult business problem. One company may pay for farmer support, new practices and measurement, while other buyers, communities and society benefit from healthier soils, lower emissions and more resilient water systems. The cost is concentrated, while the value is shared.

Closing that gap may be one of the biggest adaptation challenges ahead. It will require coalitions, public co-funding, risk-tolerant capital and credible ways of measuring outcomes. The aim must be to turn the coalition of the willing into a coalition of those who benefit.

Technology has a role to play here too. I met several start-ups working on the carbon-credit and water agendas. What stood out was their focus on using better data, measurement and technology to make environmental outcomes more credible and easier to act on.

These were early conversations, but I hope some can develop into real partnerships. The value will depend on whether the technology solves practical business problems and contributes to measurable impact, rather than simply adding another layer of reporting.

I also found it encouraging to see how much serious sustainability work is still happening in US companies. The headlines can give the impression that everything has slowed down. That was not what I saw.

People are still working on water, climate, agriculture, packaging and supply chains, not simply because these issues are fashionable, but because they increasingly affect how resilient and competitive a business can be. The language may be changing, but the underlying work remains important.

There is also a slightly uncomfortable part.

Flying to New York to talk about climate is not exactly straightforward. The footprint is real, and I do not think we should pretend otherwise.

For me, the only honest test is whether the trip leads to something that would not otherwise have happened: better questions, useful follow-ups, new collaborations or ideas that can actually be applied back home.

If it is just a badge and a few photos, it is hard to defend. If it helps move real work faster on water, agriculture, suppliers or emissions reductions, I think it can be worthwhile. But we should still be honest about the trade-off.

That was probably my main takeaway from the week. The cost of climate action is visible in budgets and investment cases. The cost of inaction is often less visible, but increasingly shows up through volatile energy prices, water stress, disrupted supply chains and pressure on agricultural production.

This is why sustainability is becoming more integrated into wider business discussions. It is not only about responding to environmental expectations. It is about understanding risk, identifying opportunity and building a business that can adapt when operating conditions change.

I came home with a few ideas to test, a few assumptions challenged and some people I want to keep speaking with. More importantly, I came home with specific points to follow up on with colleagues in Sustainability, Procurement and Supply Chain.

That is usually where the real value lies: not in the conference itself, but in whether the ideas become useful after we get home and are translated into practical, measurable impact.

Otherwise, they are just interesting conversations.
