In the UK alone, the built environment is responsible for around 25% of national greenhouse gas emissions (UKGBC, 2022). With the Paris Agreement target of net zero by 2050 embedded in policy, procurement, and planning, sustainability is now a strategic priority for the construction sector.
What is changing is the expectation of how organisations respond. Those that take a broader, more integrated approach will be better placed to meet client requirements, respond to regulation and deliver resilient projects.
At 5D, our five disciplines, Carbon & Climate, Energy, Nature, Social, and Governance, offer a more holistic way of understanding sustainability and what construction needs to focus on as expectations continue to evolve.
Carbon accountability is now a core part of UK public procurement. Under Procurement Policy Note (PPN) 006 (previously PPN 06/21), suppliers bidding for larger government contracts (officially £5 mill value plus but increasingly shifting to smaller value bids) must publish a Carbon Reduction Plan (CRP) showing their commitment to achieving net zero at the latest by 2050. There is also a growing demand to see proof of reductions over time.
Alongside this, whole-life carbon (WLC) is gaining ground. Emissions associated with materials, construction, operation and end of life are increasingly being considered together, rather than in isolation. While WLC assessments are not yet universally required across the UK, they are already mandated under the London Plan for major developments and are increasingly expected by clients and planning authorities.
Looking ahead, construction organisations will increasingly need to:
Climate risk management and resilience is also becoming more prominent, with projects expected to consider overheating, flooding, and long-term climate risks as standard.
Energy strategy is shifting beyond “buying green” towards reducing demand and ensuring buildings perform as intended in use. Mandatory schemes such as ESOS and SECR mean many large organisations already collect detailed energy data. The opportunity now is to use that insight to inform design, retrofit and operational decisions, rather than treating reporting as the end goal.
Key opportunities include:
Building Regulations Part L supports this shift, driving better fabric performance, improved airtightness and more efficient building services. Energy efficiency is now recognised as both a carbon benefit and a commercial strength. Alongside this, requirements such as EPCs and Minimum Energy Efficiency Standards reinforce the need to improve underlying building performance, particularly for existing buildings.
Protecting and nurturing nature is no longer a nice-to-have; it is part of how projects earn consent, manage risk, and create better places. Biodiversity Net Gain and Marine Net Gain has pushed this up the agenda, but the real opportunity is to treat land, water, and habitats as assets to work with, not just constraints to work around.
By 2026, project teams that handle nature well will be the ones who:
Nature is closely linked to climate resilience, community wellbeing and long-term asset value. Organisations that understand these connections often find it easier to secure planning approval, build local trust and avoid costly late-stage changes.
Social value, for construction, is about creating inclusive, healthy, and equitable environments for workers, communities, and building users.
Stakeholders increasingly want outcomes they can see safer sites, quality jobs and apprenticeships, local spend and better spaces around new developments.
The Procurement Act 2023, in force from February 2025, has embedded social value directly into public sector procurement across England and Wales using National TOMs framework and PPN002. Tenders now give meaningful weight to social outcomes alongside price and quality
Construction organisations will be expected to:
With KPIs and transparency requirements on larger contracts, social value is now a core part of winning and delivering work.
As expectations increase, clients, funders and regulators are looking beyond headline commitments to understand how sustainability is governed, managed and assured within an organisation.
In 2026, strong governance will be a key differentiator. Organisations will be expected to show that sustainability is supported by reliable data, clear accountability and embedded into everyday decision-making.
Good governance also changes how organisations approach compliance. Instead of scrambling to respond to audits, tenders or regulatory requirements as they occur, organisations with strong governance can respond confidently to demonstrate both compliance and progress.
This means:
When governance is in place, sustainability becomes practical and actionable. It supports better decisions, reduces risk, and helps organisations to move beyond minimum compliance, building long-term capability, resilience and credibility with stakeholders.
The construction industry has a critical role to play in the UK’s transition to net zero and wider sustainability goals. Organisations that align carbon, energy, nature, social value, and governance into a single, direct approach will be better placed to meet regulatory demands, client expectations and long-term environmental challenges.
