Climate Isn’t a Sustainability Conversation Anymore. It’s a Business Strategy Conversation.
I went into the opening of Climate Week NYC expecting a conversation about climate.
I left thinking much more about business.
Across discussions about energy, infrastructure, AI, capital, cities, supply chains and national security, one idea kept resurfacing: climate is no longer something companies can contain within a sustainability function or an annual CSR report. It is becoming an operating condition.
And the numbers increasingly support what I heard in the room, global energy investment is expected to reach a record $3.4 trillion in 2026, according to the International Energy Agency. About $2.2 trillion of that is projected to flow toward renewables, grids, storage, nuclear, efficiency, low-emissions fuels and electrification, compared with roughly $1.2 trillion for oil, gas and coal.
UK Foreign Secretary Ed Miliband cited that same $2.2 trillion figure from the Climate Week stage before making a broader argument: energy, economic and national security are becoming increasingly intertwined. His appeal to the room was also strikingly straightforward: “don’t give up on multilateralism.”
Whatever lens you apply, climate, economics, technology or risk, the underlying business questions are converging:
How resilient is our supply chain?
Where does our energy come from?
What risks are embedded in our infrastructure?
Where should capital be deployed today to avoid greater costs tomorrow?
And increasingly: what does the rapid expansion of AI mean for all of the above?
Resilience is becoming a business advantage
One of the clearest themes throughout the opening ceremony was resilience. Miami Mayor Eileen Higgins talked about climate risk already showing up in insurance and day-to-day costs, and about designing cities differently, from building codes to seawalls, parks and bioswales.
The conversation wasn't simply about environmental impact. It was about what keeps cities and the assets inside them functional, insurable and investable. That same thinking showed up repeatedly in discussions of corporate supply chains and infrastructure.
And companies are already encountering the practical limitations. A new Climate Group report released just ahead of Climate Week found that companies participating in its RE100 initiative collectively source 59% of their electricity from renewables. But businesses increasingly cite limited renewable supply, costs, procurement options and regulatory barriers as obstacles to going further. More than 70 members are already between 90% and 100%, while Nike announced that it has now reached 100% renewable electricity globally.
That tells me this conversation has moved beyond aspiration, and it is becoming execution.
The Future Cannot Live in the CSR Department
Business leader and former Unilever CEO Paul Polman offered perhaps the clearest provocation of the morning: “Less bad is not good anymore.”
His alternative was a shift toward thinking that is “regenerative, restorative, reparative.” Whether every organization adopts those terms isn't really the point. The larger shift is that climate considerations increasingly touch operations, finance, product development, procurement, infrastructure, innovation and technology.
Capital is following.
On the same day as the Climate Week opening, the European Investment Bank announced that a Global Green Bond Initiative being developed with the European Commission aims to mobilize up to €20 billion for green investment in emerging and developing economies.
Meanwhile, a Climate Week report released last week by energy think tank Ember argues that the energy and information revolutions are increasingly becoming one system. Five technologies underpinning both chips, batteries, power electronics, motors and sensors have fallen 99% in combined cost since 1990, according to its analysis.
This isn't simply a sustainability story, it's a business transformation story. And that has implications for marketing.
For marketers, the opportunity isn't to invent a better sustainability narrative. It's to understand how the business itself is changing and then communicate that change credibly. The strongest brand narratives are rarely created by messaging alone. They are earned through decisions: where companies invest, how they operate, what they build, what they source and how they respond to a changing world.
Communications should follow those decisions, not substitute for them.
And Then There is AI
This was probably the tension I found most interesting.
There was considerable optimism about AI's potential role in scientific discovery, energy efficiency, grid management and solving complex problems. But Siemens' Dr. Eva Riesenhuber offered a line that crystallized the issue for me: "AI has a physical manifestation: the data center.”
That deserves more attention. We tend to talk about AI through the software layer: models, agents, automation, productivity and transformation. Underneath it sits an enormous physical system.
Data centers need electricity, cooling, water, chips, land, minerals and grid capacity. And those demands are rising quickly. The International Energy Agency estimates that global data-center electricity consumption increased about 17% in 2025. Electricity consumption from AI-focused data centers grew even faster, about 50%.
So while we ask what AI can do for business, we also need to ask: What does AI require from business? And can an organization really separate its AI strategy from its infrastructure and energy strategy?
Increasingly, I don't think it can.
Both things can be true at once: AI can be an extraordinarily powerful tool for addressing complex problems, and scaling AI introduces significant infrastructure requirements of its own.
“We can do both,” MIT's Dr. Evelyn Wang told the room.
The question is how.
Greening What is Already Brown
Another concept that surfaced across multiple conversations was the need to improve what already exists rather than focusing exclusively on creating something new.
I kept thinking of it as “greening what is brown today.”
Transformation rarely comes from replacing entire systems overnight. It happens by improving existing infrastructure while building toward what comes next.
That applies to grids...buildings...transportation...supply chains.
And it certainly applies to businesses.
The transition also increasingly has an economic case behind it. IRENA reported this summer that more than 90% of utility-scale renewable projects commissioned in 2025 generated electricity for less than the cheapest new fossil-fuel alternative available in their respective markets. That doesn't eliminate the enormous infrastructure, financing and implementation challenges involved. It does change the conversation.
From Messaging to Operating Strategy
As someone who works at the intersection of marketing, business transformation and emerging technology, this may be my biggest takeaway from Climate Week: Climate isn't just a sustainability conversation anymore. It is increasingly a conversation about competitiveness, infrastructure, technology, resilience, capital and long-term business value.
And marketers should be paying attention.
Our role has always required understanding changes in technology, culture, media and consumer behavior before they completely reshape the marketplace. Climate and infrastructure belong in that conversation too. Not because every company needs to become a “climate brand.” But because every company operates inside systems that are changing.
Energy is changing. Technology is changing. Capital is changing. Infrastructure is changing.
Supply chains are changing. And the businesses capable of understanding how those forces intersect will be better equipped to determine what comes next and tell credible stories about it.
Polman ended his challenge to Climate Week attendees with something much more personal:
“Do one courageous thing.” For business leaders, that may not mean announcing another commitment. It may mean identifying one part of the business that needs to work differently and starting there.
The future isn't a communications strategy. You have to build for it first.
