What are the benefits of standards to your energy or utilities business?

Using standards can help you save energy, save money and help to save the environment. The UK business community has long used standards to improve the quality and performance of its products, reduce risk, and support reputations. Standards, which can be defined simply as ‘agreed ways of doing things, have provided firms with guidance to help them create repeatable procedures to minimize risks and operate more efficiently. Particularly in sectors highly regulated at UK and EU level, standards have been key agents in consistently preventing pollution, meeting regulatory compliance, and supporting good stakeholder relations. Standards, including rules, guidelines, and definitions, have also become recognized indicators of quality and safety. Sustainability has never been more important. But at the same time, people are more cynical than ever about ‘green’ marketing claims. They want to see proof of your utility company’s commitment to tackling environmental and social challenges. Implementing standards can help you to demonstrate your credentials to customers, employees, and stakeholders, and showcase your commitment to sustainable development.  They can help you deliver substantial environmental, economic, and social benefits, whatever your size, sector, or geographical location. They also help you to identify and manage the impact of your business on the environment and community, understand relevant legislation, and most importantly use resources more efficiently by implementing powerful policies across your organization. This not only helps the environment, but it makes a real difference to your bottom line. Widely adopted standards such as BS EN ISO 14001 and BS EN ISO 9001 (or BS EN ISO 29001:2020 for oil and gas businesses) have been important drivers of change in promoting environmental management and better quality management across the industry. But other standards related to sustainability, such as BS 8900-1 for sustainable development, have not yet achieved widespread implementation.

Understand the benefits of standards Using standards can offer a set of powerful business and marketing tools for organizations of all sizes. You can use them to fine-tune your performance and manage the risks while operating in more efficient and sustainable ways. Other benefits of implementing standards in the energy and utility sectors include: Improving performance - success is all about how you perform at every level of your organization. Standards, such as BS EN 9001 Quality management system promote a culture of continual improvement. Reducing business risk - businesses today simply can’t afford to take an improvised, reactive approach to risk. Using standards, such as BS EN ISO 22301 Business continuity management system, can help you to identify your risks and minimize them. Becoming more sustainable - by helping you to take a close look at how you’re using energy and resources, using our standards, like BS EN ISO 14001 Environmental management system, can save you money and improve your image while benefiting the environment. Encouraging innovation - in a global economy of rapidly emerging new technologies and markets, standards, such as BS ISO 44001 Collaborative business relationships management system, help set the rules and establish the frameworks to facilitate innovation through collaboration. How can standards help utility organizations implement sustainable practices? Particularly for organizations that deal with natural resources such as oil and gas, the pressure from consumers and the UK Government to switch to more sustainable practices have become hard to ignore. Standards can help make this transition easier, in turn allowing businesses to benefit from retaining and gaining new customers and maintaining a good brand reputation. Here are our recommendations on how corporates can use standards to put sustainability into operation: Leverage standards for integration and consistency, not isolated campaigns - large firms have multiple layers of complexity, from distributed and varied facility types to different strategic business units that need to engage with a single narrative on energy, environment, and sustainability. For example, the IT services firm Dimension Data, which operates four offices and a data centre in the UK, needs to involve various divisional leads to incorporate sustainability management into its operational excellence plan. The repeatable processes and procedures that follow from the implementation of standards provide the underlying structure for all the different business units to be able to implement and report on the KPIs derived from the single corporate vision on sustainability. Use management systems to move from compliance to optimization - firms operating in heavily regulated sectors, particularly basic resources, chemicals, construction, oil and gas, and utilities, have often used standards to put in place internal practices to reduce the risk and cost of operational mishaps. Building on this, these firms should look to use standards above local compliance requirements and target improving the environmental efficiency of their operations. With sustainability performance also creeping into requests for proposals (RFPs), clients increasingly will require firms to go beyond regulation-specific compliance towards strategic, globally consistent offerings that integrate new ideas such as the use of renewable energy.

Fusion energy and standards: Key insights from BSI's Net Zero Week 2025

BSI's Net Zero Week 2025 brought together experts to discuss how standards could shape fusion energy's journey from experimental reactors to the power grid. The September 22nd session on Fusion Energy and the Role of Standards revealed crucial considerations about making this promising technology commercially viable. In this article, we will explore those considerations and the standards that are helping to drive fusion energy’s transition from experimental science to commercial reality. These include how they are supporting innovation, ensuring safety and enabling the industry’s acceleration toward net zero. The industry accelerates towards net zero The UK government has demonstrated serious commitment with £2.5 billion over 5 years assigned to fusion research and development. Notably, the UK became the first country to introduce fusion-specific planning rules, signalling regulatory readiness for this emerging sector. Sebastiaan Van Dort, Director of Energy & Sustainability at BSI, described the UK's STEP (Spherical Tokamak for Energy Production) programme as aiming to build a commercial fusion power plant by 2040, "really creating a hub of clean energy innovation." As the world looks toward fusion energy as a source of clean, abundant, and reliable power, one often-overlooked question is emerging at the heart of the discussion: what role will standards play in enabling its success? Fusion’s standardization gap Dr Isobel Houghton, Chief Engineer at AtkinsRéalis and Chair of NCE/1 Nuclear Coordination Committee, noted that very few standards have been written expressly for fusion. Today the core published set is limited to: BS ISO 4233:2023 Reactor technology — Nuclear fusion reactors — Hot-helium leak-testing method for high-temperature pressure-bearing components (NCE/3) BS EN ISO 16646:2025 Nuclear installations — Criteria for the design and operation of confinement and ventilation systems of tritium-handling fusion facilities (NCE/2) ISO 18518:2025 Safety-system requirements for superconducting technology in nuclear-fusion facilities (NCE/2) BS ISO 20041-1:2022 Tritium and carbon-14 activity in gaseous effluents — Part 1: Sampling (NCE/2) BS ISO 20041-2:2025 Tritium and carbon-14 activity in gaseous effluents — Part 2: Activity determination by bubbling technique (NCE/2) BS ISO 14152:2001 Neutron radiation-protection shielding — Design principles and material selection Yet, beyond these niches a large standardization gap remains.  Dr Houghton noted that this is not a flaw but the natural result of rapid technical evolution and diverse reactor designs. Without an overarching structure, however, detailed standards could lag behind progress. Her recommendation is to develop a high-level, principle-based framework now. That framework would let detailed requirements mature alongside technology, keeping safety, interoperability and quality aligned without stifling innovation. Dr Mutaz Bashir, Principal Engineering Analyst at United Kingdom Atomic Energy Authority (UKAEA), agreed. “Commercial fusion in both private and public sectors is now taking big strides.” Many engineering challenges are common across reactor concepts, providing fertile ground for shared solutions and, ultimately, shared standards. Finding the right level for fusion standards Dr. Isobel Houghton posed a critical question that cuts to the heart of the standardization challenge: "At what level do you standardize?" This seemingly simple question opens complex considerations for an industry still defining itself. Dr. Houghton clarified NCE/1's (BSI’s nuclear coordination committee’s) strategic approach: while it's too early for prescriptive technical standards that might lock in specific fusion technologies, there's significant opportunity for standards that enable the industry's development.  She advocated for capturing "current fusion specific best practice from across the world" and sharing that understanding through "recommended practices, design guides, technical notes." An industrial parallel: The Whitworth Screw Thread To illustrate the transformative power of standardization, Dr Houghton shared a compelling historical example from the early Industrial Revolution. Before the introduction of Whitworth screw threads, each engineer or manufacturer produced nuts and bolts with their own unique dimensions. A bolt made in one workshop might not fit a nut made in another, creating enormous inefficiencies and hampering collaboration. When Sir Joseph Whitworth proposed a standardized screw thread in the 1840s, it changed everything. Interchangeable parts became possible, enabling mass production, easier maintenance and faster technological progress. Houghton used this analogy to underline how fusion energy could similarly benefit. By adopting shared standards early, the sector could avoid fragmentation, accelerate commercial readiness and establish global trust in fusion systems and components. The approach requires careful balance. Standards need to be complementary and not too prescriptive. Dr. Houghton noted that "BSI is ideally placed with support from the UK experts... to lead development of the standards that we're going to need for fusion to realise UK's ambition to become a global leader in commercial fusion energy." Dr. Houghton also made a point that cuts straight to fusion's commercial reality. "Without safety, nobody has a commercial proposition. No one is going to invest in a fusion powered plant that isn't considered safe. It won't get a licence." This highlights how safety standards aren't bureaucratic obstacles to fusion energy, but rather the foundation that transforms fusion from an exciting science project into an investable clean energy proposition. Building on proven foundations Dr. Bashir highlighted a pragmatic approach, that fusion doesn't need to reinvent the wheel. He noted that "many of the key engineering challenges are largely common" across different fusion projects and even with other industries. This cross-pollination of knowledge means fusion can adapt proven solutions from sectors that have already tackled similar challenges. The AI integration challenge Dr. Amanda Niedfeldt, Head of Business Development at DigiLab, brought another dimension to the discussion — the role of advanced AI in fusion operations and regulation. As AI systems take on increasing responsibilities in fusion facilities, the need for robust frameworks becomes paramount. She argued that while some industries limit AI’s use in safety-critical systems, fusion presents a unique opportunity to integrate AI more deeply - not just for monitoring, but for adaptive control, predictive maintenance, and design optimization. Using her concept of an "AI adoption iceberg," she explained that building the model is just the visible tip, but underneath lie challenges of reproducibility, security, data sovereignty and cultural alignment. The challenge, she noted, will be ensuring that standards for AI in fusion remain flexible and future-oriented, so they can adapt as both the technology and regulatory expectations evolve. Niedfeldt emphasized that trustworthiness emerges as an essential framework for human adoption, particularly when there's risk and concern. She noted that standards for AI in fusion must address not just technical performance but also the transparency and explainability needed to build confidence in these systems. Standardization here isn’t about constraining innovation, but about providing the guardrails for trustworthy, safe deployment. Standards making a real world difference for fusion energy The panel referenced the UK's STEP programme when discussing how standards apply to real fusion projects. STEP aims to build a prototype fusion energy plant, a significant undertaking that illustrates why getting standards right matters. The key insight was that standards for such pioneering programmes must walk a fine line - robust enough to ensure safety and compatibility, flexible enough to accommodate first-of-a-kind innovations. Decisions about standards made now will shape whether various global efforts can learn from each other and build toward a unified industry. Dr. Bashir emphasized that "collaboration & coordination is critical for realising these engineering challenges." He called for fusion experts to "cluster around standard development organizations to proactively help and support with the development of these codes and standards," noting that these organizations offer platforms for this work. The panel stressed the importance of avoiding competing standards to prevent industry fragmentation, while maintaining the flexibility needed for continued innovation. This collaborative approach is essential for fusion's success. With commercial fusion taking big strides, the panel indicated the industry stands at an important moment. Investment is accelerating and multiple approaches are being pursued globally. The discussion emphasized how decisions about standards made now will shape whether these various efforts can learn from each other and build toward a unified industry. The critical juncture: The path forward Dr. Houghton's closing recommendation to policymakers was unequivocal. "Be really clear about what it is that we're trying to achieve with fusion and be really clear that we want to collaborate. We don't want to work on this alone...it's got to be a collaborative effort." She emphasized the importance of international cooperation, stating "we need to be really clear as policymakers that we collaborate internationally, not compete." Van Dort concluded that this conversation represents "just the beginning." With fusion technology advancing and major investments flowing, the industry must balance innovation with the frameworks needed for safe, efficient deployment. The session underscored that fusion's success requires not just solving technical challenges but creating the standards and common approaches that enable safe, efficient deployment.  For those watching the energy transition, the message from Net Zero Week was clear: fusion is making real progress, and standards are the crucial enabler that will help transform scientific achievement into commercial reality.

Sustainable energy management standards: A framework for responsible businesses

Global energy consumption has risen steadily over the past century, driven by strong economic growth and an ever-increasing population. This demand puts increasing pressure on our natural resources, whilst continued use of fossil fuels contributes directly to pollution and global greenhouse emissions. And, despite mounting environmental concerns, it continues to rise. In its 2016 International Energy Outlook report, the US Energy Information Administration (EIA) projected a 48% increase in world energy consumption from 2012 to 2040. A significant change in direction is required to ensure adequate energy supply for all. To minimize environmental impact, and achieve long-term sustainable economic growth, organizations worldwide must take the necessary measures to offset their consumption of energy resources. Energy management standards, like BS EN ISO 50001, can help businesses to implement energy management solutions, increasing their energy saving as they become more climate neutral. Sustainable energy management standards A standards-based approach to sustainable energy management enables businesses to measure and monitor their energy use, identify and manage risks, and improve performance through cutting consumption and energy bills. Sustainable energy management standards also promote corporate social responsibility (CSR), enhancing a company’s image and offering a competitive advantage, along with a greater return. As it stands today, effective energy management isn’t just good for business; it’s also becoming a requirement. Regulation, such as the UK Government’s Energy Savings Opportunity Scheme (ESOS), has put energy use high on the corporate agenda. As such, many businesses have started to invest time and budget into reviewing their current consumption, identifying cost-saving opportunities that will safeguard their business and protect the planet (and its populations) – now and for the future. To commit to sustainable energy management and comply with legislation where required, organizations must take an integrated approach, embedding the sustainability agenda into their core business strategy. As part of this strategy, a structured energy management system is required. The BS EN ISO 50001 standard can help all businesses deliver this, regardless of size, location, or industry. Even smaller companies, with limited financial and technical resources, will feel the practical benefits of introducing organizational change. In fact, The Carbon Trust has found that low and no-cost actions can reduce an organization’s energy costs by at least 10%, producing quick returns on investment. To learn more about the benefits of standards for energy organizations, click here. In addition to BS EN ISO 50001, the BS EN ISO 14000 family of standards, such as BS EN ISO 14001 and BS EN ISO 14006, provide practical tools that enable organizations to set up an effective environmental management system. These energy management standards help firms introduce targeted initiatives for reducing raw material use, energy consumption, and disposal costs.  Such energy management best practice guidance will become increasingly valuable as the environmental context in which businesses operate changes. The worldwide application of an international standard like BS EN ISO 50001 also contributes to more efficient use of available energy sources, and to reducing greenhouse gas emissions and other related environmental impacts – including waste and pollution. As such, it is inextricably linked to the UN’s 17 Sustainable Development Goals (SDGs). Energy management: Meeting the UN’s Sustainable Development Goals Efficient energy use relates directly to SDG 7, which aims to ensure universal access to “affordable, reliable, sustainable and modern energy”. This is essential in reaching overall climate change mitigation goals (SDG 13). It also: contributes to furthering long-term economic growth (SDG 8); aids in the transition to smart, sustainable cities (SDG 11); and ensures responsible consumption of natural resources (SDG 12). This shows that by proactively taking steps to manage energy more efficiently, organizations will help facilitate the achievement of all 17 goals. Start managing your energy more efficiently by implementing energy management standard BS EN ISO 50001 into your organization.
