“Net zero” has become one of the most widely used—and often misunderstood—terms in sustainability.
For some organizations, it is a long-term ambition. For others, it is already a formal commitment tied to investor expectations, regulatory pressure, or public disclosure. But regardless of where a company is in its journey, one thing is true across the board: net zero is not a single action or project. Net zero is a transformation of how an organization operates, consumes energy, and manages emissions across its entire value chain.
Understanding what net zero actually requires is the first step toward building a strategy that is both credible and achievable.
Net zero is not zero emissions
At its core, net zero means balancing greenhouse gas emissions with removals. More specifically, it is the point where human-caused emissions released into the atmosphere are matched by an equivalent amount of emissions removed, resulting in a net impact of zero.
Net zero does not mean an organization can continue emitting at the same level and simply offset everything. The current scientific and market consensus is that companies must first reduce the vast majority of their emissions, and only then neutralize what remains.
What credible net zero targets require
The strongest global guidance today comes from the Science Based Targets initiative (SBTi), which provides a framework for companies to align with a 1.5°C climate pathway.
Under that approach, net zero is built on three core expectations:
- Deep emissions reductions across Scopes 1, 2, and 3
- Near-term targets (often to 2030) and long-term targets (typically 2050 or sooner)
- Neutralization of residual emissions that cannot be eliminated
Most companies are expected to reduce emissions by roughly 90–95% before relying on carbon removal for the remainder.
This is an important shift from earlier approaches that leaned more heavily on offsets. Today, the emphasis is on real operational decarbonization first.
Why net zero is more complex than it looks
Net zero touches every part of an organization. It is not just an energy issue or a reporting issue. It involves:
- building operations
- energy procurement
- supply chain emissions
- capital planning
- asset performance
- data systems and reporting
For real estate portfolios, this complexity shows up clearly. Scope 2 emissions from electricity use may be a major driver, but Scope 3 emissions from tenant activity, materials, and supply chains often represent a large share of the footprint.
Because of this, net zero strategies tend to expand over time. What starts as an energy-efficiency effort often becomes a broader portfolio and value-chain transformation.
The difference between net zero and “carbon neutral”
These terms are often used interchangeably, but they are not the same.
- Carbon neutral typically means offsetting emissions to reach a net balance
- Net zero requires deep emissions reductions first, with limited use of removals for the remaining emissions
In other words, net zero sets a higher bar. It is focused on eliminating emissions at the source wherever possible, not just compensating for them.
Where organizations typically struggle
Understandably, most challenges with net zero come from execution. It’s easy to define and publicize a net zero goal, but as the underlying work begins to rear its head, organizations run into challenges.
Common ones include:
- incomplete or inconsistent emissions data
- limited visibility into Scope 3 emissions
- difficulty aligning operational teams with sustainability goals
- unclear ownership across departments
- overreliance on future solutions rather than near-term action
- lack of a clear pathway from current state to target
A more practical approach to net zero
Organizations tend to make more progress when, from the beginning, they treat net zero as a series of coordinated steps rather than a single long-term target. It’s also important to identify the steps prior to publishing the goal, so as not to be accused of “greenwashing”.
Start with a clear baseline
Understanding current emissions across Scopes 1, 2, and 3 is essential. Without a reliable baseline, it is difficult to prioritize actions or measure progress.
Focus on near-term reductions first
Long-term targets matter, but most frameworks emphasize near-term action. Reducing emissions in the next 5–10 years is critical to staying aligned with climate goals.
Address the biggest drivers
Not all emissions sources carry the same weight. Identifying the largest contributors—whether that is electricity use, fuel consumption, or supply chain activity—helps focus effort where it will have the greatest impact.
Integrate operations and strategy
Net zero is not achieved through reporting alone. It requires changes in how buildings operate, how energy is sourced, and how assets are managed over time.
Plan for what cannot yet be eliminated
Even with strong reduction efforts, some emissions may remain. A credible strategy includes a plan for neutralizing those residual emissions using durable removal solutions.
The role of real-time and interval data in net zero
Of course, data plays a central role in making net zero actionable. High-level annual data can support reporting, but it is often not enough to drive operational change. More detailed data—such as interval and real-time energy information—helps teams:
- identify inefficiencies
- manage peak demand
- optimize equipment performance
- reduce unnecessary energy use
- validate the impact of improvements
Net zero strategies increasingly depend on stronger data visibility and availability, not just emissions calculations.
Why transparency matters
Net zero commitments are under increasing scrutiny. Stakeholders—including investors, regulators, and customers—are paying closer attention to:
- how targets are defined
- what is included in scope
- how progress is measured
- how much of the strategy relies on offsets versus reductions
What we’re seeing now is an effort against greenwashing and towards: more detailed disclosures, clearer methodologies, and stronger alignment with recognized standards. Organizations that are transparent about their assumptions, limitations, and progress tend to build more credibility over time
Net zero expectations are changing
Net zero is still evolving. Key trends shaping the current landscape include:
- stronger emphasis on Scope 3 emissions
- reduced reliance on offsets and greater focus on actual reductions
- tighter alignment with science-based frameworks
- increased integration with financial and risk disclosures
- more scrutiny around claims and definitions
We can expect net zero to continue moving toward more scrutiny, more rigor, more consistency, and more accountability.
How Tango Helps
Tango Energy & Sustainability helps organizations build the data and operational foundation needed to support net zero goals.
By bringing together utility data, interval data, emissions tracking, and portfolio-level insight, Tango enables teams to better understand where emissions are coming from, how they are changing, and where action will have the greatest impact.
That kind of visibility is critical for turning net zero from a long-term commitment into a set of practical, measurable actions. Organizations that treat net zero as an ongoing operational priority—not just a future milestone—are the ones most likely to make meaningful progress.
