How to align your carbon credit strategy with the Oxford Offsetting Principles

Sustainability managers are increasingly looking to align their net-zero strategies with credible, science-based frameworks. But the carbon market is complex, and the definition of a "high-quality" credit has changed.

Recognizing that the vast majority of offsetting today is still not net-zero aligned, the University of Oxford created the Oxford Principles for Net Zero Aligned Carbon Offsetting. The report calls for a major course correction in how organizations use carbon markets, emphasizing the urgent need to close the carbon removal gap.

What exactly changed, and how does it impact your procurement strategy? In this blog, we will break down the 4 principles and show you how to build a future-proof, high-integrity carbon portfolio.

The shift from carbon neutral to true net zero

Before diving into the principles, it is important to understand the terminology. Historically, companies claimed to be "carbon neutral" by purchasing cheap avoidance credits to compensate for their total remaining emissions. The latest Oxford Principles distance themselves from this approach, noting that "carbon neutral" was often used as a non rigorous claim.

Real net-zero requires science-based emission reductions, with any remaining residual emissions fully compensated exclusively by carbon removals with a low risk of reversal.

The 4 Oxford Offsetting Principles (Latest revision)

To achieve a net-zero commitment, the Oxford Principles outline four critical steps:

1. Cut emissions and ensure environmental integrity

You cannot offset your way out of the climate crisis. Every credible strategy must start with internal reduction.

• Prioritize value chain reductions: minimize the need for offsetting by reducing your direct and indirect emissions first.
• Ensure strict integrity: any credits you purchase must be measurable, verifiable, and additional. They must have a low risk of reversal and avoid negative impacts on local communities and ecosystems.
• Maintain transparency: disclose your current emissions, your transition plans, and the exact type of credits you use.

2. Transition to carbon removal offsetting

Today, the voluntary carbon market is still dominated by credits from emission reductions. While these are valuable in the short term to protect vulnerable ecosystems, they cannot get us to global net-zero. To align with this principle, organizations must take the following steps:

• Shift your portfolio: You must actively transition your offsetting portfolio away from avoidance credits and toward carbon removals.
• Reach the end goal: Your portfolio must ultimately consist of 100% carbon removal credits to counterbalance residual emissions by your net-zero target date.

3. Shift to removals with durable storage

Not all carbon removals are created equal. Nature-based storage (like planting trees) is crucial but carries a higher risk of the carbon being released back into the atmosphere due to climate shocks like wildfires or disease. To ensure true permanence, your strategy should focus on:

• Low risk of reversal: To maintain a true net-zero balance, you must shift toward storage methods with high durability over the long term (centuries to millennia).
• Scale geological storage: This includes storing CO₂ in geological reservoirs or Biochar and Enhanced Weathering. Because current deployment of these durable methods is well below what is needed, early investment from corporate buyers is critical to scale them up.

4. Support innovative and integrated approaches

The market for high-quality, durable removals is immature and needs early adopters to survive and scale. You can catalyze this market by:

• Using offtake agreements: engage in long-term purchase agreements to give project developers the financial certainty they need to raise capital. You can read more about offtakes in this beginner guide on offtake agreements.
• Supporting nature broadly: invest in the protection and restoration of ecosystems for their own biodiversity and adaptation benefits, not solely to generate carbon credits for your own compensation claims.

What this means for your carbon credit strategy

The 2024 Oxford Principles make one thing very clear: treating carbon credits as a cheap compliance tool is no longer viable.

To align with best practices, sustainability managers must move away from opaque brokers who hide project details and mark-ups. The transparency required by Principle 1 is harder if you don't know exactly where your money is going. Furthermore, securing access to scarce, highly durable carbon removals (Principle 3) requires more direct relationships with project developers through mechanisms such as offtake agreements.
