Sustainability’s Biggest Challenge Isn’t Strategy—It’s Implementation

Over the past decade, many companies have made significant progress in defining their sustainability ambitions. Companies at the forefront of sustainability have conducted materiality assessments, set climate and social targets, published transition plans, and embedded sustainability into corporate strategy.

Yet for many organizations, one challenge remains unresolved: how do you turn strategy into meaningful business action? This was the key refrain in all conversations at London Climate Action Week 2026.

While strategic priorities are often well established, translating them into day-to-day business decisions, operational processes, and measurable outcomes remains difficult. As expectations from regulators, investors, customers, and employees continue to rise, companies are under increasing pressure to demonstrate not just commitments but credible progress.

• Business Transformation
• Sustainability Leadership

These are not isolated challenges. They are systemic implementation challenges that organizations across sectors continue to face.

Companies that successfully implement sustainability strategies are not simply improving ESG performance; they are strengthening core business performance. Embedding sustainability into decision-making helps organizations better manage risk, improve operational resilience, allocate capital more effectively, strengthen supplier relationships, respond to evolving regulation, and identify opportunities for innovation and growth. In contrast, organizations that struggle with implementation often find themselves falling short of their ambitious commitments, resulting in missed targets, inefficient investments, fragmented decision-making, and increasing scrutiny from stakeholders.

Implementation is therefore no longer a sustainability challenge alone—it is a business transformation challenge.

How BSR Can Help

One reason implementation remains difficult is that companies rarely have opportunities to discuss it openly. Strategies are often shared publicly, but implementation challenges tend to remain behind closed doors. Yet many of the most valuable insights come from understanding how organizations have navigated trade-offs, aligned internal stakeholders, engaged suppliers, or adapted implementation approaches as business conditions changed.

Creating structured opportunities for peer learning allows companies to move beyond theory and accelerate progress through practical experience.

This is where BSR comes in. To help companies navigate these challenges, BSR has launched the Operationalizing Sustainability Roundtable, a peer-learning forum dedicated to one question: How do companies successfully implement sustainability?

Over six facilitated sessions, senior sustainability leaders bring live implementation challenges and work through them with peers from across industries. We will focus our discussions on the six key enablers of successful implementation, which are internal, external, and systemic: 

Internal Enablers of Successful Implementation: 

1. Leadership that drives ownership and accountability: Executive endorsement is important, but implementation requires active leadership. Successful implementation requires business leaders to own sustainability outcomes, embed priorities into business planning, and create momentum across functions.

2. Governance that creates cross-functional collaboration: Clear governance enables consistent execution across an organization. Sustainability is not a siloed issue, but must be taken on throughout organizations. Roles, responsibilities, decision rights, performance metrics, and incentives all need to reinforce implementation rather than create competing priorities.

3. Financial planning that supports implementation and long-term action: We too often hear companies highlight the lack of budget put toward sustainability implementation and efforts. Sustainability becomes scalable when it is integrated into financial planning, capital allocation, enterprise risk management, procurement, and investment decisions—not managed as a separate workstream.

External Enablers of Successful Implementation:

4. Supplier partnerships that deliver results: Much of a company's sustainability impact sits within its value chain, where companies have little control to take unilateral action. Successful implementation will require deep collaboration and long-term supplier partnerships, which can help build capability, encourage innovation, and improve long-term resilience across the supply chain. For implementation to be successful, we need to move beyond reporting and compliance in the value chain toward implementation-focused partnerships.

5. Delivery models that can enable on-the-ground implementation: Many impacts that companies aim to mitigate happen to communities in the supply chain. In order to implement successful programs that tackle these actions, companies need to work with local partners and NGOs to tailor programs to local contexts. Without local partnerships, implementation on the ground is likely to be unsuccessful.

Systemic Action for Successful Implementation

6. Collective action that tackles systemic barriers: Most sustainability challenges cannot be solved by individual companies acting alone. Industry collaboration and thoughtful policy engagement can help address shared barriers, establish common approaches, and accelerate implementation across entire sectors.

Within our discussions, rather than prescribing a single solution, the roundtable creates a space for companies to test ideas, learn from real-world experience, and develop practical approaches they can take back into their organizations. Participants also receive a synthesis of key implementation insights and emerging practices to inform future decision-making.

At a time when sustainability is judged by outcomes rather than intentions, building implementation capability is becoming a source of competitive advantage. Organizations that can consistently translate commitments into operational decisions will be better positioned to manage risk, create long-term value, strengthen stakeholder trust, and deliver meaningful environmental and social impact. The Operationalizing Sustainability Roundtable is designed to help companies build exactly those capabilities.
