In today’s business environment, sustainability and ESG (Environmental, Social, and Governance) considerations are no longer optional—they are increasingly central to how organisations evaluate potential suppliers.
For companies bidding on tenders, understanding how ESG is scored and integrated into decision-making can mean the difference between winning and losing a contract. From public sector procurement in the UK to private corporate tenders, ESG credentials are being actively measured, benchmarked, and weighted against traditional criteria such as price, quality, and experience.
In 2026 and beyond, businesses that grasp ESG scoring and incorporate it effectively into their tender submissions will have a distinct competitive edge.
What ESG Means In Tendering
ESG is a framework that assesses an organisation’s commitment to sustainable and responsible business practices. It is divided into three main components:
Environmental – how a company manages its impact on the planet, including energy consumption, carbon footprint, waste management, and resource efficiency.
Social – how the business engages with people, communities, and stakeholders. This includes employee wellbeing, diversity and inclusion, community engagement, and health and safety standards.
Governance – the systems and processes that ensure accountability, transparency, and ethical decision-making, including anti-corruption policies, board diversity, and risk management.
In tendering, these three pillars are assessed to determine how responsibly a business operates and whether it aligns with the values of the buyer. Increasingly, organisations are using ESG scoring as a formal component of tender evaluation, assigning quantitative scores to demonstrate commitment and performance.
How ESG Scoring Works
ESG scoring is essentially a way for procurement teams to evaluate the non-financial credentials of potential suppliers. While the exact methodology can vary, most scoring systems assess three key areas: policy and strategy, measurable impact, and reporting.
Policy And Strategy: Buyers look for documented policies that demonstrate a proactive approach to ESG. For example, a company might have a carbon reduction strategy, a social responsibility plan, or a governance code of conduct. The presence of well-defined policies shows that sustainability is embedded in corporate strategy rather than being an afterthought.
Measurable Impact: Policies alone are not enough. Tender evaluators increasingly seek evidence of tangible results. For environmental criteria, this might include energy usage reductions, waste diversion rates, or carbon footprint reporting. For social criteria, metrics could include employee retention, training hours, or community investment. Governance can be assessed through internal audits, compliance certifications, or independent oversight.
Reporting And Transparency: Clear and accurate reporting is vital. Organisations that can provide ESG reports aligned with recognised standards—such as GRI (Global Reporting Initiative), CDP (Carbon Disclosure Project), or ISO certifications—tend to score higher. Transparency demonstrates accountability and builds trust with buyers.
ESG Weighting In Tenders
The weight assigned to ESG in tender evaluation varies depending on the sector and buyer. In the public sector, especially in the UK, ESG is becoming increasingly formalised. Under frameworks such as the Social Value Act 2012, public bodies are required to consider social, environmental, and economic value when awarding contracts. This can result in ESG being weighted anywhere from 10% to 30% of the overall evaluation score.
In private sector tenders, ESG weighting may be less prescriptive but is often still significant. Corporate clients increasingly prefer suppliers who demonstrate responsible practices, both to meet internal sustainability targets and to protect their reputation. A company with strong ESG credentials can often outperform competitors on tender submissions, even if their pricing is slightly higher, because the buyer values long-term sustainability over short-term cost.
The Common Pitfalls In ESG Tender Submissions
Despite the growing importance of ESG, many companies struggle to score highly due to these common mistakes:
Generic Statements: Simply stating “we care about sustainability” is insufficient. Evaluators look for specific policies, measurable outcomes, and evidence of impact.
Lack of Data: Without quantifiable metrics, it’s difficult to demonstrate progress or effectiveness. Buyers want numbers, percentages, and concrete examples.
Non-Aligned Practices: Submitting ESG policies that don’t align with the buyer’s values or sector priorities can result in low scores. For example, a construction tender may prioritise energy efficiency and local employment; a generic CSR statement won’t suffice.
Poor Documentation: Failing to provide clear reports, certifications, or verifiable evidence can undermine otherwise strong ESG initiatives.
How To Improve ESG Scoring
To maximise the ESG score in tenders, companies should:
Develop A Clear ESG Strategy: Ensure that environmental, social, and governance objectives are integrated into core operations, not treated as an add-on.
Measure And Monitor Performance: Track key indicators such as carbon footprint, employee engagement, or compliance audit results. Quantifiable results strengthen tender submissions.
Provide Evidence: Include certificates, case studies, third-party audits, or reports that validate ESG claims.
Align With Buyer Priorities: Review the tender requirements carefully and tailor your ESG responses to match the specific criteria or objectives outlined.
Regularly Update Policies: ESG standards evolve rapidly. Keeping policies current and relevant ensures your submission reflects best practice and innovation.
ESG As A Competitive Advantage In Tendering
ESG scoring is no longer a peripheral consideration—it is a critical factor that can determine success in both public and private sector tenders. Understanding how evaluators assess environmental, social, and governance credentials allows businesses to present their sustainability efforts in a clear, measurable, and compelling way.
Companies that invest in robust ESG policies, monitor performance, and provide transparent evidence will not only improve their chances of winning tenders but also strengthen their overall brand reputation, operational efficiency, and stakeholder trust. In 2026, mastering ESG scoring is no longer just about compliance—it is about gaining a competitive edge in an increasingly values-driven market.
