Growing Gap Between Sustainability Ambition and Delivery
Execution confidence drops sharply below executive level
A new study from the Project Management Institute and Green Project Management reveals a troubling disconnect. Most sustainability executives believe their organisations will hit their targets. However, confidence drops sharply among the people responsible for delivery.
The research surveyed nearly 1,600 professionals across 35 countries. It found that 85% of sustainability executives expect their organisations to meet sustainability goals. Meanwhile, just 43% of project management office leaders share that optimism. Among project professionals doing the actual work, confidence falls to 20%.
This gap matters because it points to a structural problem. Organisations are setting ambitious sustainability commitments without building the delivery capacity to match. Consequently, the risk is not just reputational damage. Increasingly, access to climate finance and ESG investment depends on proof of delivery, not promises.
Project delivery remains disconnected from sustainability priorities
The report, titled Executing Sustainability Strategy: When Ambition Meets Reality, identifies a fundamental integration problem. While 79% of respondents say sustainability is important to long-term success, only 41% confirm it is fully embedded in projects and daily operations.
In addition, 59% of organisations have not fully integrated sustainability into project delivery and operational decision-making. This suggests that many businesses treat sustainability as a separate function rather than a core part of how work gets done.
The research also found that sustainability is the strongest predictor of project success. It ranks ahead of governance structures and project methodologies. Therefore, organisations that fail to embed sustainability into delivery frameworks may be undermining their own project performance.
Six recurring barriers block sustainability delivery
The study identifies six specific obstacles that prevent organisations from turning sustainability ambitions into results. These barriers appear consistently across sectors and geographies.
First, many organisations struggle to quantify sustainability benefits in business terms. Without clear financial or operational metrics, sustainability projects compete poorly for resources. Second, weak integration into decision-making means sustainability considerations are often bolted on rather than built in.
Third, unclear goals make it difficult for project teams to know what success looks like. Fourth, competing priorities push sustainability down the agenda when budgets tighten. Fifth, limited visibility into outcomes makes it hard to track progress in real time. Finally, difficulty tracking long-term results means organisations cannot demonstrate impact to investors or regulators.
George Asamani, Managing Director of PMI Sub-Saharan Africa, framed the challenge bluntly. He said sustainability is no longer a separate conversation from business performance. However, the real challenge is delivery. He added that a strategy does not build a power station, expand broadband access, or improve water security. Projects do.
African progress on development goals remains insufficient
The execution gap identified in the PMI research mirrors broader challenges across Africa. The continent is making measurable progress on the United Nations Sustainable Development Goals, but not fast enough to meet the 2030 deadline under current trajectories.
The 2026 Africa Sustainable Development Report was released in April and presented publicly in July. It was produced jointly by the African Union Commission, African Development Bank, United Nations Development Programme, and United Nations Economic Commission for Africa. The report confirms that Africa has made gains across 12 of the 17 SDGs. Nevertheless, progress on five priority goals remains insufficient for 2030 delivery if current trends continue.
This matters because development finance, climate funding, and ESG-linked capital are increasingly tied to measurable outcomes rather than stated ambition. Investors and multilateral institutions want evidence of impact, not just policy frameworks. Therefore, the ability to deliver projects that produce verifiable results is becoming a commercial and strategic necessity.
Financing gaps, institutional constraints, and fragmented implementation are slowing progress on critical development and infrastructure goals. For governments, public agencies, and private firms, this creates pressure to improve project management discipline and measurement systems.
What separates successful organisations from the rest
The research identifies two traits shared by organisations that consistently deliver on sustainability commitments. First, leadership teams align on what success means. This includes clear definitions, measurable targets, and shared accountability. Second, these organisations translate sustainability priorities into project-level decisions and actions.
This second point is critical. It is not enough to set high-level targets or publish sustainability reports. Success requires embedding sustainability criteria into project selection, resource allocation, risk assessment, and performance tracking. In other words, sustainability must become part of the operational DNA, not a separate initiative managed by a specialist team.
For UK businesses operating in Africa or working with African partners, this has direct implications. Suppliers increasingly face sustainability requirements in tender processes. Public sector procurement in particular now includes carbon reporting and environmental standards. Companies that cannot demonstrate delivery capability risk losing access to contracts and funding.
Essential facts about the execution gap
- The study surveyed nearly 1,600 professionals across 35 countries, revealing a 65-percentage-point confidence gap between executives and project professionals on sustainability delivery.
- Only 41% of organisations have fully integrated sustainability into projects and daily operations, despite 79% recognising its importance to long-term success.
- Sustainability is the strongest predictor of project success, outperforming governance structures and project methodologies as a success factor.
- Africa has made measurable progress on 12 of the 17 Sustainable Development Goals, but five priority goals remain off track for 2030 delivery under current trends.
- Access to climate finance and ESG investment increasingly depends on proof of delivery, not policy statements or sustainability reports alone.
- Organisations struggle most with quantifying sustainability benefits in business terms and tracking long-term results against stated objectives.
Delivery capacity must match strategic ambition
The core issue is not that sustainability is losing momentum. Rather, many organisations lack the project management discipline, governance alignment, and measurement systems needed to deliver at scale. This gap between ambition and execution creates strategic risk.
For African markets, the challenge is particularly acute. SDG timelines are tightening, and investment flows increasingly depend on evidence of impact. Companies and governments that cannot demonstrate delivery capability will struggle to access funding. Moreover, they will lose competitive advantage in procurement processes that now include sustainability criteria as standard.
UK businesses with African operations or supply chains need to pay close attention. Sustainability is no longer a separate workstream. It is becoming a core project management discipline. Consequently, firms that treat it as a compliance exercise rather than an operational priority risk being left behind.
The research also suggests a practical starting point. Leadership alignment on clear, measurable goals is the foundation. From there, organisations must build the systems and skills to translate those goals into project-level decisions. This includes training project managers, revising decision-making frameworks, and implementing tracking systems that provide real-time visibility into sustainability outcomes.
For smaller businesses, this may sound daunting. However, the alternative is worse. As ESG criteria become embedded in procurement, finance, and regulation, the cost of inaction will increase. Businesses that invest now in building delivery capacity will have a significant advantage over those that wait.
We work with UK businesses to build carbon reporting and compliance systems that meet procurement requirements and support funding applications. This includes helping firms embed sustainability into project management processes, not just governance documents. The organisations we work with understand that sustainability is not a separate function. It is a delivery discipline that affects every project and every decision.
In addition, the shift towards evidence-based sustainability is changing how investors evaluate risk. Companies that cannot demonstrate progress against stated targets face higher capital costs and limited access to ESG-linked finance. Therefore, building the internal capacity to track, measure, and report on sustainability outcomes is no longer optional. It is a commercial requirement.
Where to find additional guidance and data
The full PMI and Green Project Management report, Executing Sustainability Strategy: When Ambition Meets Reality, is available from the Project Management Institute. It includes sector-specific findings and regional breakdowns that may be relevant to your industry.
The 2026 Africa Sustainable Development Report is published by the United Nations Economic Commission for Africa. It provides detailed analysis of progress against the SDGs and identifies priority areas for investment and policy reform.
For UK businesses working in African markets or with African partners, the Department for Business and Trade offers country-specific guidance on sustainability requirements and procurement standards. This includes information on ESG due diligence and supply chain transparency obligations.
Finally, organisations looking to improve project management capability around sustainability should review guidance from the Institute of Environmental Management and Assessment. It provides practical frameworks for embedding environmental and social considerations into project delivery processes.
