If you've spent any time following the latest discussions around Scope 3 accounting, you've probably heard the term "Market-Based Instruments" (MBIs) more frequently over the past year.

While the term “Market-Based Instruments" is new, it is being used to describe the connection of familiar mechanisms – such as greenhouse gas reductions, carbon removals, water improvements, or biodiversity benefits – and corporate sustainability reporting. MBIs are gaining attention because they may help address one of the biggest challenges in agricultural supply chains: how to recognize and report sustainability outcomes when physical traceability is incomplete or impractical.

For companies working toward ambitious Scope 3 goals, that's a conversation worth paying attention to.

What Exactly Is a Market-Based Instrument?

Put simply, a Market-Based Instrument is a mechanism that allows an environmental outcome to be measured, documented, transferred, and ultimately claimed by another party. It’s a framework for defining ownership and responsibility around environmental benefits.

A well-designed MBI answers a few critical questions:

• What environmental outcome was created?
• Who funded or enabled that outcome?
• Who has the right to report or claim it?
• How is it verified?
• How do we prevent multiple parties from claiming the same benefit?

Those questions become increasingly important in food and agriculture, where commodities are routinely blended, aggregated, processed, and shipped through highly complex supply chains.

Why Are MBIs Becoming Important?

Most corporate Scope 3 programs today rely on physical inventories and varying levels of supply chain traceability. That's still the foundation of credible reporting, and it's not going away.

The challenge is that many sustainability investments occur in places where physical traceability is difficult. A company may invest millions of dollars helping farmers adopt regenerative practices, but the resulting environmental benefits may not always flow neatly through a supply chain that allows every outcome to be physically connected to every finished product.

This is where MBIs enter the conversation.

The goal is not to replace physical inventories. The goal is to create additional mechanisms that help companies account for verified environmental outcomes while maintaining transparency about what is being reported and why.

The Reporting Landscape Is Changing

One reason MBIs are receiving so much attention is that several leading standards organizations and industry initiatives are actively exploring how environmental outcomes can be accounted for and reported beyond traditional physical inventories.

The Greenhouse Gas Protocol's Actions and Market Instruments (AMI) initiative is one of the most prominent examples. The program is evaluating a potential "multi-statement" reporting framework that could allow companies to report climate impacts through multiple ledgers, including physical inventories, market-based inventories, GHG impact statements, and non-GHG indicators.

At the same time, the Value Change Initiative (VCI) has been examining how environmental outcomes, including emissions reductions and carbon removals, can be recognized and transferred across agricultural value chains. A key focus of the discussion has been finding practical approaches for complex food systems where physical traceability is often limited, while still maintaining transparency, credibility, and alignment with emerging standards.

Together, these efforts reflect a broader shift in thinking. Rather than asking companies to force every sustainability outcome into a single reporting framework, the bodies setting the standards are exploring how different types of environmental outcomes can be measured, verified, and communicated in ways that better reflect the realities of agricultural supply chains.

For companies investing heavily in regenerative agriculture, this could eventually create new opportunities to communicate the impact of sustainability programs that are difficult to capture within today's reporting structures.

It's important to note that these frameworks are still under development. Questions around governance, ownership, quality criteria, and safeguards against double counting remain active areas of discussion. At HabiTerre, we’ll continue to work to be a part of these discussions whenever possible. 

A Word of Caution

The growing interest in MBIs has created plenty of excitement, but also legitimate concerns, specifically around credibility.

Questions around ownership, double counting, transparency, and verification still need clear answers. If multiple parties can claim the same outcome, or if standards are inconsistent, the result is confusion at best and greenwashing at worst.

That's why HabiTerre's position has been consistent: any future MBI framework must maintain the same rigor and transparency expected within established GHG accounting systems.

MBIs should expand reporting options. They should not become a shortcut around sound accounting practices.

Where SYMFONI Fits

Regardless of where the standards land, one thing is becoming increasingly clear: companies will need systems capable of managing environmental outcomes with the same level of rigor they manage physical supply chains.

That's where SYMFONI comes in.

The platform was built to quantify, verify, track, and manage sustainability outcomes across agricultural value chains. Whether the future involves environmental attribute certificates, market-based inventories, carbon removals, biodiversity claims, or reporting frameworks that have yet to be finalized, the underlying requirements remain remarkably similar.

Companies need trusted data. They need transparent records. They need clear ownership and chain-of-custody information.

SYMFONI was designed to provide that infrastructure.

As Market-Based Instruments continue to evolve, we believe the platform is well-positioned to support the creation and management of many, if not most, of the MBI models currently being discussed.

Looking Ahead

Market-Based Instruments are not a silver bullet for Scope 3 reporting. They won't eliminate the need for strong data, traceability, or credible accounting practices. What they may do is create new pathways for recognizing environmental outcomes across complex agricultural supply chains. We’ll continue to take an active role in these conversations and pay close attention to developments so we are prepared to support our customers.
