Since the adoption of the Paris Agreement, net zero has moved from the margins of climate policy to the center of the global economic conversation. Governments have set targets, corporations have issued commitments, and investors have embedded climate expectations into capital markets.
Yet those working inside sustainability know that the global net zero movement still remains deeply fragmented.
Part of the challenge begins with definition. Net zero is interpreted differently across sectors, geographies and regulatory systems. Some organizations measure only Scope 1 emissions, while others include Scopes 1 and 2. Some focus solely on operational carbon while overlooking embodied carbon, while others attempt to account for supply chains and Scope 3. Meanwhile, different standards, frameworks, platforms, and measurement tools are being used simultaneously across markets.
This fragmentation is not just a technical challenge – it’s one of the most significant barriers to meaningful climate progress.
I would argue that at its core, climate transformation ultimately comes down to something very simple: math. If emissions can’t be measured consistently, they can’t be managed effectively. And if they can’t be managed effectively, they can’t be reduced at scale.
For many years, sustainability conversations have been dominated by frameworks, labels, and announcements. Programs such as LEED, Energy Star, BREEAM, Passive House, and the Living Building Challenge have done tremendous service to the movement by raising awareness, helping bring sustainability into the mainstream and creating momentum for environmental leadership. Their impact cannot be overstated.
But the next phase of this movement requires something different. It requires operational clarity, measurement discipline, and practical roadmaps that organizations can implement across portfolios and supply chains to achieve net zero performance.
Yesterday’s sustainability goals cannot drive tomorrow’s outcomes.
Across the global economy, leaders are now asking a far more practical and urgent question: How do we actually implement net zero? That shift — from aspiration to implementation and execution — is where the real work begins.
From Fragmentation to Alignment: Why Net Zero Must Become a Measurement Discipline
Today’s climate landscape reflects a complex web of commitments, certifications and reporting requirements. Organizations often find themselves navigating multiple disclosure frameworks and sustainability programs simultaneously.
Even within the building sector – which is rightly considered one of the most advanced arenas of climate action – leaders sometimes struggle to determine whether their progress represents genuine emissions reductions or simply well-presented reporting. Rating system fatigue is real and has been for a very long time. Data is tracked across different platforms using different methodologies, and organizations pursue multiple certifications that are rarely harmonized. This is both time consuming and expensive.
To be clear, plaques and public announcements still attract attention. But they do not always reflect comprehensive emissions reductions across energy, water, waste, and supply chains.
This is where the conversation must mature.
The true value proposition of net zero is not branding: It’s fundamentally a math problem. When emissions are measured transparently and consistently across Scope 1, Scope 2, and Scope 3, ambition becomes something tangible. It becomes something that can be planned, financed, and executed. Numbers transform sustainability from an abstract concept into a management discipline — and once that happens, progress becomes far more predictable.
This is precisely the role the Global Network for Zero was designed to play. GNFZ is building a shared foundation of transparent measurement that harmonizes systems and standards across sectors and scales. By grounding performance in science-based measurement aligned with the GHG Protocol, organizations can focus on what truly matters: actual emissions reductions. In doing so, net zero ambition becomes strategic, verifiable, and replicable — helping move the market from aspiration toward real-world impact.
Why Measurement and Networks Have More Impact than Frameworks
When Sarah Merricks and I founded GNFZ, we were very deliberate about what we did not want to create. The world does not need another rating system. Organizations are already navigating a crowded landscape of disclosures, certifications, and reporting obligations. Adding another layer of complexity would not accelerate change.
Instead, we focused on the barriers preventing the broader building market from moving toward net zero – particularly existing buildings, which represent most of the global building stock, yet often face the greatest barriers to implementing sustainability and decarbonizing.
We also did extensive market research, speaking with business leaders, asset managers, and policy leaders across the U.S. working on decarbonization. During these conversations, we heard a consistent message: Existing sustainability programs worked extremely well for the top performers in the market, but large portions of the market — especially existing buildings and mid-to-lower performing portfolios — felt left behind.
I have long emphasized the idea of “all buildings in.”
If the world is going to achieve net zero, the transformation cannot be limited to the top 10 percent of buildings. It must extend across the entire market.
Roughly 92% of Fortune 500 companies use the GHG Protocol for GHG accounting, so we developed our net zero certification around it. The platform takes an incremental approach to certification, allowing organizations at different performance levels to build practical roadmaps that move their assets toward net zero over time.
But we also knew certification alone would not be enough. From the beginning, our ambition was to build something larger: A global network of leaders working together to accelerate the realization of a zero-emissions world.
There is power in networks. Networks enable cross-sector collaboration, shared intelligence, faster iteration, peer accountability, and honest conversations about what is and isn’t working.
You cannot standardize your way out of fragmentation. But you can convene your way out of it.
Global Progress Rarely Looks the Way We Expect
Another lesson from working across global markets is that decarbonization leadership rarely emerges from the places people initially expect. When I launched the LEED Zero program during my time at the U.S. Green Building Council, many observers assumed early adoption would come from flagship buildings in major global cities. Instead, some of the first adopters emerged from smaller U.S. and Latin American markets.
Today, we are seeing something similar in India, which is rapidly becoming one of the most active markets for net zero buildings anywhere in the world. India’s long-term climate commitments are closely tied to a broader national vision for economic development and modernization. Rapid urbanization means much of the country’s future building stock is still being constructed, creating an enormous opportunity to embed performance standards today rather than retrofit inefficiencies tomorrow.
My global travels have shown me that around the world, different regions move forward using different levers. In Europe, policy clarity often leads the market. In the U.S., capital markets, local city leadership, and incentives play powerful roles. In parts of Asia, scale and urban integration accelerate adoption. In the Middle East, centralized investment and technology deployment are major drivers.
I’ve seen that long-term success, however, requires alignment across the board – between policy, finance, technology and culture. When those forces move together, progress accelerates.
The Mindset Shift That Could Accelerate Everything
If there is one change that could dramatically accelerate global progress, it is this: A move from guarded positioning to shared learning. Too often organizations feel pressure to present perfect case studies. Only the successes are highlighted, while implementation challenges remain private.
But climate transformation is complex, execution is messy, and every organization is learning in real time. When leaders share only polished outcomes, markets learn slower than they should. Real acceleration happens when leaders are willing to say, “This investment delivered faster returns than expected,” “This strategy stalled because we underestimated supply chain complexity,” or “This approach worked in one region but not in another.”
Transparency builds trust. Trust builds collaboration. And collaboration reduces duplication of mistakes.
In a global challenge like decarbonization, that kind of shared learning is one of the most powerful accelerators we have as it helps close the loop on the business case for decarbonization. It is also the core idea behind networks.
The Decade Ahead
The decade ahead will be one of the most consequential periods in the history of climate action. I hope this phase of the net zero movement will be remembered as the period where we finally moved from ambition to implementation.
The organizations that lead the next decade of climate progress will not be those making the biggest announcements. Instead, they will be the ones embedding emissions data into procurement decisions, capital planning, infrastructure investments, and supply-chain strategies. In other words, they will treat climate strategy as an operational discipline.
At GNFZ, we are deeply grateful for the growing global network of practitioners, advisors, and partners who are working alongside us to turn ambition into implementation. Together, we are building a network that is focused not on promises – but on progress you can measure, defend, and scale.
