With the UK government’s ambitions to reach net zero by 2050, organisations are increasingly faced with carbon reporting requirements, environmental targets and growing stakeholder expectations. Most organisations begin by trying to measure emissions. Yet carbon is often a symptom and the real problem and challenge to overcome is waste. Here, Noel Ferguson, Head of Net Zero Energy Solutions at Trident Utilities outlines why many organisations are approaching net zero from the wrong direction…
Net zero has quickly become a mainstream concept, with every organisation impacted in some form, be it through government policy, supply chain demands or corporate strategies and regulatory obligations. They know they need to cut carbon, but carbon can be a difficult concept to understand and accurately measure.
With emissions split across Scope 1, 2 and 3 categories, understanding what should be measured and how to reduce it is complicated. Scope 3 emissions can account for up to 90 per cent of an organisation’s carbon footprint yet often rely on inconsistent supplier data and complex reporting methods. For many employees, carbon metrics often feel abstract and disconnected from their day-to-day responsibilities.
Waste, by contrast, is tangible and is also the root cause of many emissions. It’s visible on the factory floor, in warehouses, offices and across transport operations. People understand wasted energy, unnecessary journeys, excess materials and inefficient processes because they see their impact daily. Reframing carbon reduction as waste reduction makes sustainability more practical and relatable. It’s easier to act upon, such as the simple act of turning off a light.
Waste can sneak into all areas of an organisation. Inefficient equipment uses more energy, poorly controlled heating, ventilation and air conditioning systems waste electricity and fuel. Waste materials, like those that are scrapped or reworked, carry embodied carbon that has already been generated during their production. Even poor procurement decisions can drive avoidable emissions through unnecessary consumption and inefficient supply chains. By reducing waste at source, organisations can often reduce emissions as a natural consequence.
In many respects, a waste first approach to net zero builds on principles that organisations already understand. Continuous improvements, the Six Sigma method to reduce defects, errors and variation and lean manufacturing have long led organisations to focus on identifying and eliminating waste to improve performance. But what has changed in recent years is the recognition that many of these inefficiencies also carry a carbon cost. Applying carbon to these principles can accelerate decarbonisation through existing organisational culture and operations.
And if we start to think of net zero in this way, it no longer becomes a standalone environmental initiative but becomes an extension of operational excellence. This distinction is important because many decarbonisation strategies focus heavily on reporting outcomes rather than addressing the underlying cause. While quick wins like renewable energy procurement, for example, can significantly reduce Scope 2 emissions it doesn’t address why energy is being consumed in the first place. An organisation can purchase 100 per cent renewable electricity and still consume excessive amounts through inefficient motors, outdated lighting systems and poorly controlled building services. Real change requires reducing avoidable consumption, not simply changing the source of supply.
The commercial benefits of cutting waste are equally compelling. Waste is expensive. Energy waste increases operating costs and increases exposure to volatile energy markets. Transport, for example, one of the UK’s largest emitting sectors, accounting for around 30 per cent of emissions, can be responsible for increased fuel consumption and fleet costs if not run efficiently. Poor inventory management creates materials waste while inefficient workflows, downtime and duplication reduce productivity levels. In every case, reducing waste not only improves environmental performance but also financial performance. In energy, it’s often said, the cheapest kWh is the one you don’t use, and the same principle applies to tonnes, litres or whatever metric you use.
While in many respects waste is easy to understand, there is still a challenge in that much of it remains hidden. Organisations often lack the skills or capabilities to accurately monitor where resources are being consumed and an understanding of where improvements could be made. This is where advances in data and technology are becoming increasingly important.
Real-time energy monitoring can identify waste hotspots and abnormal consumption, and cameras and analytics systems can optimise production processes while maintaining product quality. Using artificial intelligence (AI) to interpret operational data, spreadsheets and historical records can reduce manual admin and help identify trends and inefficiencies that would otherwise remain hidden. These technologies are allowing more organisations to move beyond reporting to proactively tackling waste.
Perhaps most importantly, a waste-first approach can also create greater engagement across the workforce. While employees might struggle to connect with carbon reporting frameworks, they can easily understand waste, the value in it and how they can play a direct role in reducing it. This fosters a culture of continuous improvement that benefits both the organisation and its sustainability objectives.
Ultimately, the organisations making the fastest progress to net zero are often those focusing less on carbon and more on the operational waste that drives emissions. By identifying waste, measuring it, then systematically eliminating it, organisations can both reduce emissions and improve operational efficiency, resilience and profitability. Â In many ways, net zero becomes far clearer and easier to achieve when we start with waste and when the conversation shifts from abstract carbon metrics to practical operational improvements everyone can understand, influence and deliver.
