Strengthening Tender Responses: Why ESG and Social Value Are Now Competitive Differentiators

Tenders are evolving, and fast. Where cost and technical capability once dominated, Environmental, Social and Governance (ESG) considerations are now an increasingly prominent part of procurement processes. For organisations bidding for work, this shift presents both a challenge and an opportunity:  those who can demonstrate credible, organisation-wide ESG practices are increasingly outperforming those who cannot.

Insights from recent engagement with Business Working Responsibly Mark-certified companies across sectors reinforce a consistent theme: ESG is now present in most tenders, but its weighting can vary widely and, on average, remains relatively low in Ireland. While this may suggest ESG is still peripheral, the direction of travel is clear. Policy drivers, regulatory developments, and supply chain expectations are accelerating its importance, particularly in the public sector, where scrutiny can be deeper and more strategic. Its influence on final decisions is already growing — particularly in competitive or strategically significant bids.

A clear illustration of this shift can be seen in the way organisations such as Iarnród Éireann (Irish Rail) approach procurement. At a recent workshop for Mark Certified companies, they shared how they are actively embedding sustainability and social value into their procurement processes. Sean McCaffrey, Supplier Performance Manager with Iarnród Éireann, commented, “traditionally people would consider things like cost and quality, while Sustainable procurement is more of a holistic approach, where you are considering certain impacts around environmental and social considerations.”  This reflects a broader shift: procurement is no longer purely transactional but a strategic lever for delivering environmental and societal outcomes.

For suppliers, this changes what constitutes a strong tender response. Increasingly, organisations are expected to demonstrate how they will deliver measurable sustainability commitments over the life of a contract — including how these will be implemented, monitored and reported. This type of approach signals a move towards more structured, outcome-focused ESG requirements that go beyond high-level commitments.

Growing prominence of social value

One notable development is the growing prominence of social value. While environmental criteria have historically dominated, organisations are increasingly asked more frequent and nuanced questions about community impact, inclusion and broader societal benefit. This reflects a wider shift in procurement thinking – viewing each contract not just as a transaction but as an opportunity to deliver positive outcomes for people, communities and the environment.

What Differentiates Winning Tender Responses?

At a practical level, the fundamentals are consistent. Successful organisations are investing in internal coordination – bringing together subject matter experts early and maintaining central repositories of ESG data, case studies and evidence. They are moving beyond generic policy statements and instead providing tailored, contract-specific responses supported by measurable data. Increasingly, procurement teams are looking for proof; not just commitments, but evidence of implementation, monitoring and continuous improvement.

Why Structure and Certification Matter

This is where structured approaches to ESG can make a real difference. Organisations that have embedded ESG across their governance, strategy and operations are better placed to respond efficiently and credibly. They can draw on established processes, verified data and consistent narratives, rather than starting from scratch with each submission.

Third-party frameworks and certifications, such as the Business Working Responsibly Mark, also play an important role in this context. Used effectively, they can help anchor responses and offer a coherent structure for communicating ESG practices. Importantly, their value lies not simply in being mentioned, but in how they are integrated into the overall narrative of the bid: supporting claims, reinforcing credibility, and connecting different elements of the response.

Increasingly, organisations are looking to structured frameworks, such as the Business Working Responsibly Mark, not as a standalone credential but as a practical way to strengthen governance, organise evidence and enhance the credibility of their tender responses. As Ivan Ahern, Managing Director at Cornmarket Group Financial Services, commented, “Organisations are increasingly expected to demonstrate not only strong governance and environmental practices, but also meaningful social impact. Achieving a recognised ESG accreditation such as ‘The Mark’ has helped Cornmarket clearly evidence our commitment in these areas, providing assurance to clients and stakeholders while strengthening our position in competitive tender submissions.”

For businesses, the message is clear. As ESG expectations continue to evolve, the bar for “what good looks like” in tender responses is rising. Organisations are being asked not only what they do, but how systematically and transparently they do it. In parallel, social value is becoming a more meaningful differentiator, requiring bidders to think more holistically about their impact.

While ESG may not yet carry the highest weighting, it is increasingly influencing outcomes – particularly in competitive or strategically important bids. Those who invest now in building robust, evidence-based ESG approaches will be better placed to respond with confidence, differentiate themselves in the market and meet the expectations of buyers who are steadily raising the bar.
