Returns were once the only metric that mattered. That math has changed, as institutional investors and businesses increasingly adopt impact and sustainability goals and seek competitive returns alongside lasting benefits for communities and the environment.  

This means seeking alternatives to bring into practice the triple bottom line (TBL) framework: Profit (economic value), People (social responsibility), and Planet (environmental stewardship), coined by John Elkington in 1994. In response, Sustainability Week connects investors with innovators and entrepreneurs behind opportunities and potential projects across the region.

Sustainability Week's goal is clear: to scale up existing partnerships and forge new ones that mobilize private investment, with a primary focus on scaling up impact and accelerating development across Latin America and the Caribbean.  

This ambition reflects a broader shift in global capital markets. ESG-related assets are projected to exceed $40 trillion by 2030, according to the Bloomberg Intelligence ESG report. This growing pool of capital underscores both the opportunity and the need to channel private investment toward projects that deliver measurable impact.  

Achieving this requires collaboration across a diverse mix of stakeholders. That’s why Sustainability Week will convene corporate executives, institutional investors, impact funds, development finance leaders, multilateral and bilateral institutions, sustainability experts, policymakers, innovators, and entrepreneurs in Barbados.  

The event was designed as a hybrid, multi-moment platform that invites audiences worldwide to join online and engage with the ideas, partnerships, and investments shaping sustainable economic outcomes for Latin America and the Caribbean.  

IDB Invest: A Partner of Choice  

At Sustainability Week, investors and business leaders will share practical solutions and build strategic partnerships to de-risk investments and increase the regional supply of bankable projects that meet investors’ requirements and growing demand for sustainable private assets.  

To help advance these objectives, IDB Invest brings deep regional, on-the-ground expertise to support projects following its Originate-to-Share approach – originating and structuring projects and then bringing in private investors by anchoring transactions that mobilize capital for sustainable investments across the region.  

At the forum, this approach translates into efforts to foster alliances and advance financing structures that can be replicated, such as the landmark blue bond issuance that channeled long-term institutional capital into sewage infrastructure serving 2.5 million people in São Paulo, Brazil.  

In financial health, IDB Invest partners with institutions such as Fundación Génesis Empresarial to expand access to finance in rural areas and to support income generation among underserved communities in Guatemala.  

Together, these examples illustrate the type of sustainable, bankable investments that Sustainability Week seeks to advance and demonstrate how IDB Invest serves as a partner of choice in structuring, de-risking, and mobilizing private capital toward scalable impact.  

Sustainability Week 2026 provides a unique platform to connect capital with opportunities that can be scaled across Latin America and the Caribbean. By highlighting bankable projects, replicable financing structures, and cross-sector partnerships, the forum underscores how sustainable investment can deliver attractive returns for investors and both resilience and long-term economic benefits for communities.  

Whether through infrastructure, innovation, or financial health, Sustainability Week showcases the conditions needed to turn ideas into concrete outcomes and accelerate the flow of private capital toward impact.
