For many project managers, the word sustainability still brings to mind construction projects: lower-carbon concrete, energy-efficient buildings, reduced waste and environmentally responsible supply chains. That association is completely understandable. The environmental consequences of decisions made on major construction and infrastructure projects can last for decades.
But the construction industry is not the only sector where sustainability matters so it’s a blinkered view to not consider it in other industries.
For instance, a software implementation has a sustainability footprint. So does a pharmaceutical development programme, a hospital transformation, a manufacturing project, a financial-services change programme and the launch of a new consumer product.
The impacts may be less immediately visible than a motorway, factory or office building, but the fundamental project management issue is the same – is something being delivered that creates lasting value without creating unacceptable environmental, social or economic costs elsewhere.
This is increasingly becoming part of what successful project delivery means – balancing environmental, social and economic considerations while also meeting current stakeholder needs without disadvantaging future generations. That means sustainability is more than simply an environmental initiative.
It, perhaps, also raises an uncomfortable question for the project profession. Can projects be considered genuinely successful if their long-term consequences are unsustainable? In which case are the standard success indicators (time, budget etc.) no longer enough.
The definition of project success is changing
Traditional project management measures, of course, are still vitally important. Cost, schedule, scope, quality and risk cannot simply be discarded because of wider sustainability objectives. But they no longer fully define a successful project.
Imagine a new office development delivered precisely on schedule and within its approved budget. Five years later it requires substantially more energy than anticipated, is expensive to maintain and needs significant retrofitting.
Was that project successful?
Or consider a technology transformation delivered to specification that requires substantially greater computing resources (i.e. energy) than anticipated and creates an expensive dependency on obsolete infrastructure.
A manufacturing improvement project might successfully reduce the unit cost of production while increasing energy consumption or making products considerably harder to repair and recycle.
A healthcare transformation might achieve its financial savings while inadvertently making services less accessible to vulnerable patients.
All four projects could potentially look successful on a conventional project dashboard at the point of handover, but projects can have consequences way into the future. That distinction is fundamental to sustainable project management.
Project managers naturally concentrate on getting something delivered whereas sustainability issues require broader consideration of what happens once a project has been delivered.
Recent research suggests organisations increasingly recognise this connection. PMI and Green Project Management reported in 2026 that 79% of respondents believed sustainability positioned their organisations for long-term success. Yet only 41% said sustainability was fully integrated across projects and functions. There was also a striking difference between leadership confidence and delivery confidence: 85% of sustainability executives believed their organisations could achieve their objectives, compared with just 20% of project professionals.
Sustainability needs to begin before delivery
One of the greatest mistakes organisations can make is treating sustainability as something that can be added to a project once the major decisions have already been made. By then, many of the most consequential choices may already be locked in.
A construction project may already have selected its materials and structural solution. A technology programme may already have chosen its architecture and cloud infrastructure. A manufacturer may already have designed a product around components that are difficult to repair or recycle. A hospital programme may already have designed a service that assumes patients have reliable digital access.
For a project to be genuinely sustainable these fundamental decisions need to be made at the start of the project – at the project initiation stage and within the business case.
This has implications in all areas of a project in almost every sector:
- Cost is no longer just about building or implementing but about the cost to own, operate, maintain and eventually replace or dispose of the project deliverable.
- Schedule is no longer just about meeting a specific delivery date but also about decisions that may impact the delivered project over the next, say, 5 years.
- The project’s environmental impact is no longer just about the immediate impact but the consequences throughout the lifecycle.
Construction projects: looking beyond operational carbon
Construction remains the obvious example because sustainability decisions are literally embedded in the finished product. Material selection, embodied carbon, energy consumption, water use, waste, biodiversity, transportation, local communities and eventual demolition or reuse can all be affected by project decisions.
There is also a danger that an environmentally efficient building is automatically assumed to be a sustainable project. Yet complying with current benchmarks is not enough without also considering longevity and potential future replacement and rework of the building
As an example, the cheapest material at procurement may not be the cheapest across a 30 years project life expectancy.
This is where sustainability becomes particularly interesting for project managers: it can encourage solutions that address several project objectives simultaneously rather than simply adding another constraint.
Technology: digital doesn’t mean impact-free
Technology projects can sometimes appear almost detached from physical resources. Yet cloud computing, data centres, AI systems, hardware manufacturing and data storage all consume energy and physical resources. Hardware also eventually becomes electronic waste.
Sustainable technology project management therefore raises questions that may never have appeared on a traditional IT project plan.
For instance, does every piece of data really need to be retained indefinitely? Are computing resources being massively over-provisioned? Can existing hardware remain useful for longer? What happens to devices at their end of life?
AI makes these questions even more relevant because organisations are rapidly launching AI projects without always considering the resources required to operate them at scale.
But environmental impact is only one factor. A sustainable digital transformation also needs to consider accessibility, inclusion and human consequences. A project that moves an essential service entirely online might reduce operating costs and paper consumption while simultaneously excluding people with poor digital skills, disabilities or inadequate internet access.
The environmental benefit does not automatically outweigh the social cost so sustainable project management requires both to be considered.
Healthcare: sustainability is also about people
Healthcare provides an especially useful illustration of why sustainability cannot simply mean carbon reduction. Hospitals and healthcare systems certainly have environmental footprints: buildings require heating and cooling, clinical activities generate waste, supply chains are extensive and equipment consumes energy and materials. But healthcare projects also have profound social consequences.
Consider a project to redesign outpatient services around remote consultations. Potential benefits could include fewer patient journeys, reduced demand for physical facilities, lower travel emissions and greater convenience. But the project manager also needs to ask who might be disadvantaged.
Could elderly patients struggle with the technology? Could people with particular disabilities find remote consultations less accessible? Do all patients have appropriate devices and reliable connectivity? Are there clinical situations where virtual delivery is simply inappropriate?
None of those arguments necessarily mean the project should be abandoned but they do mean that the necessary trade-offs to achieving sustainability goals needs to be well-understood, documented and discussed at project initiation.
Manufacturing: design decisions can determine decades of waste
For manufacturing, sustainability increasingly begins at product design rather than at the factory recycling bin. Project teams launching new products make decisions about materials, suppliers, packaging, manufacturing methods, energy requirements, durability, repairability and eventual disposal.
That creates an important shift in thinking away from simply a focus on efficiency at the manufacturing stage to an understanding of what happens to a product throughout its entire life and when it reaches end-of-life.
A product that costs slightly more to manufacture but lasts twice as long could ultimately consume fewer resources. A modular product might allow individual components to be replaced instead of the entire unit. Packaging might be redesigned to use less material while simultaneously reducing transportation weight.
This is closely connected with the idea of a circular economy, where products and materials remain useful for as long as possible rather than following a simple extract-manufacture-use-dispose model.
And again, project managers are well placed to influence these outcomes because the critical decisions occur during projects.
Energy: sustainability includes the transition itself
The energy sector presents an interesting paradox. Renewable-energy and decarbonisation projects may have sustainability as their explicit purpose, but that doesn’t automatically make every aspect of their delivery sustainable.
A wind farm, solar installation, battery facility or electricity-grid project still consumes materials, affects landscapes, involves supply chains and potentially impacts communities and ecosystems. Therefore, project managers have to consider not only what the project contributes, but how the project itself is delivered. There can also be difficult trade-offs between environmental objectives.
For instance, infrastructure required for decarbonisation might affect biodiversity. New transmission infrastructure may encounter significant community opposition. Critical minerals needed for batteries and renewable technologies have their own environmental and social supply-chain implications.
Sustainability considerations rarely have a simple right answer. They often require balancing competing forms of value.
Financial services: an apparently low-carbon project can have enormous indirect consequences
Banking, insurance and investment projects illustrate particularly well why sustainability cannot be assessed solely by looking at the project’s immediate physical footprint.
Take a project to create a new lending product as an example. It may appear to involve little more than people, software and data. Yet the lending decisions enabled by that system could influence billions of pounds of economic activity.
Similarly, projects involving investment platforms, insurance products or pension systems can affect which activities receive capital and which risks are priced into future decisions. There are also important social sustainability questions.
Does a new financial product improve or reduce financial inclusion? Could automation unintentionally disadvantage particular groups? Are customers able to understand the decisions being made about them? Does an AI-driven system introduce biases that were not present before, or merely exposes biases that already existed?
Therefore, sustainable project management in financial services involves governance, ethics and long-term societal consequences as much as electricity consumption.
Retail and consumer goods: sustainability reaches through the supply chain
A retailer redesigning packaging, introducing a new logistics system or launching an e-commerce platform may make decisions affecting thousands of suppliers and millions of individual transactions. Small project decisions can therefore become significant when multiplied at scale.
A few grams less packaging per product may seem insignificant until millions of products are sold. A small improvement in vehicle utilisation could translate into thousands of avoided journeys. Changing supplier requirements might influence environmental or labour standards far beyond the organisation itself. Procurement consequently becomes a sustainability issue for project managers.
Sustainability should become part of project governance
All of this means sustainability needs to become part of normal project management decision-making and to genuinely influence decisions. That could involve:
- incorporating sustainability criteria into the business case, requirements and success measures
- considering sustainability when selecting suppliers
- including environmental and social impacts within risk management
- evaluating lifecycle costs rather than simply implementation costs
- ensuring sustainability measures remain visible through governance and reporting
Managing the inevitable compromises
The chances of perfect sustainable solutions existing is unlikely on most projects so perhaps the most valuable contribution for project managers is identifying and making compromises. Thos brings us to familiar territory for project managers for whom compromise is part of their role. Project management has always involved balancing competing constraints and sustainability simply broadens the range of consequences to be discussed and agreed.
Project managers need the confidence to prevent sustainability being side-lined whenever the schedule slips or the budget comes under pressure. If they don’t do that then sustainability will only be an aspiration not a project objective.
From sustainability to regeneration
There is an even more thought-provoking development emerging within the project profession that takes us from sustainability to regeneration. Instead of focusing on minimising environmental impact, consider whether projects can make positive improvements.
A good example of that is the circular economy where the sustainable objective of reducing manufacturing waste becomes about designing materials to create a genuinely circular system in which there is no waste.
That may sound ambitious but projects are, by their very nature, about creating change so project management could be where those ambitions start to become reality.
