Mass Balance Series | Part 4
Changing the Narrative: Why Mass Balance Should Be Seen as a Transition, Not a Shortcut
Mass balance is often criticised because it does not provide a perfect representation of physical material flows. However, expecting perfection risks overlooking its real value. As businesses work to decarbonise increasingly complex global supply chains, mass balance provides a practical mechanism for supporting lower carbon fuels and technologies while the infrastructure needed for a fully decarbonised future continues to develop. Rather than asking whether mass balance is the finished solution, the more important question is whether it helps accelerate meaningful progress. Increasingly, the answer is yes.
It is not a guarantee that a specific shipment has been transported using a particular sustainable fuel. It does not eliminate emissions overnight, nor does it remove the need for direct investment in cleaner vehicles, renewable fuels or more efficient logistics networks. For some, these limitations are enough to question whether mass balance should play a role in corporate decarbonisation strategies at all. However, this perspective risks overlooking a fundamental reality of industrial transition.
Very few technologies or systems begin at full scale. Renewable electricity, battery electric vehicles, offshore wind and even recycling systems all relied on transitional mechanisms that created demand before infrastructure could fully meet market needs. Businesses invested early, governments introduced supportive policies and industries gradually scaled production until those technologies became commercially viable.
Lower carbon fuels, electrified freight and circular materials all require significant investment before they become widely available. Waiting until those solutions are fully mature before supporting them would only delay the transition businesses are trying to achieve.
This is where mass balance provides value. Rather than waiting for dedicated green supply chains to emerge, businesses can begin supporting lower carbon fuels and materials through recognised accounting frameworks that direct investment towards the technologies needed most.
Every verified purchase of sustainable aviation fuel, renewable marine fuel or lower carbon material helps create demand. That demand encourages producers to increase capacity, gives investors greater confidence and supports the development of the infrastructure required for wider adoption. In other words, mass balance helps bridge the gap between today’s industrial reality and tomorrow’s lower carbon economy. It should not be viewed as the destination. It is part of the journey.
One of the strongest themes running through this series has been the importance of collaboration. No single organisation can decarbonise global supply chains on its own. Manufacturers depend on suppliers, retailers rely on logistics providers, shipping companies need fuel producers, and infrastructure developers require long-term market confidence before making significant investments. Mass balance reflects this interconnected reality.
Rather than placing responsibility on one organisation, it allows businesses across the value chain to contribute towards the transition. Cargo owners can support lower carbon shipping, logistics providers can invest in cleaner operations, and fuel producers gain the confidence needed to expand production. Each participant plays a role in accelerating progress. This collaborative approach is increasingly becoming one of the defining characteristics of successful decarbonisation strategies.
Standards, certification schemes and digital registries will continue to develop, ensuring businesses have greater confidence in how sustainability attributes are verified, transferred and reported. Regulatory frameworks are also likely to become more sophisticated as governments seek greater consistency in environmental claims and carbon accounting.
This evolution should be viewed as a sign of a maturing market rather than evidence that the approach itself is flawed. Every emerging system develops over time. The important point is that businesses, industry bodies and policymakers continue working together to strengthen the frameworks that underpin it. The greater the confidence in those systems, the greater the confidence organisations will have to invest in lower carbon solutions.
Too often, discussions become polarised between those who see it as the answer to supply chain decarbonisation and those who dismiss it as little more than creative carbon accounting. The reality sits somewhere in the middle.
Mass balance is neither a replacement for direct emissions reductions nor an excuse to delay meaningful action. Businesses must continue investing in operational efficiency, electrification, renewable energy and lower carbon fuels wherever those opportunities exist.
At the same time, it is equally unrealistic to expect every organisation to wait until dedicated low carbon supply chains are fully established before taking action. In many sectors, that infrastructure simply does not yet exist at the scale required. Mass balance provides a practical mechanism that allows businesses to begin supporting that transition today.
As the logistics industry continues its journey towards net zero, the conversation around mass balance needs to evolve. The question should not be whether it is perfect. Very few transition mechanisms are. Instead, we should ask whether it encourages investment in lower carbon technologies, helps scale emerging markets, supports collaboration across supply chains and enables businesses to reduce emissions while infrastructure continues to develop. If the answer to those questions is yes, then mass balance has an important role to play.
Like many of the technologies shaping the future of sustainable logistics, it represents a stepping stone rather than a final destination. Its purpose is not to replace direct decarbonisation, but to make that decarbonisation possible at scale.
Ultimately, mass balance should be judged not by whether it delivers a perfect system today, but by whether it helps build a better one for tomorrow.
Rather than viewing mass balance as a shortcut or a cheat, we should recognise it for what it is: a transition mechanism that enables businesses to make meaningful progress today while helping to build the lower carbon supply chains of the future.
