Takeaways

• The Impact Disclosure Taskforce SME Subgroup (IDTSME) has unveiled a global roadmap to bridge the $4 trillion sustainability finance gap for small and medium-sized enterprises (SMEs).
• The Whitepaper, launched during Climate Week NYC, calls for redesigned financial systems, digital innovations, and regional labs to expand SME access to impact capital.
• Africa’s scale-up model serves as proof that localized, inclusive financing can drive both economic and climate resilience.

A global coalition has announced a major push to close the $4 trillion sustainability finance gap affecting small and medium-sized enterprises (SMEs), a sector vital to both the economy and the planet’s climate goals. The Impact Disclosure Taskforce SME Subgroup (IDTSME), supported by Legacy Global, unveiled its new Whitepaper, “Scaling Private Company Impact Finance,” at the NEST Climate Summit during Climate Week NYC.

The report presents a blueprint to mobilize sustainable capital for SMEs, which make up over 90% of global businesses and employ more than half the world’s workforce. Yet, less than 10% of global climate finance reaches them, according to data from the OECD, IFC, and Climate Policy Initiative.

“The world cannot meet its climate and sustainability goals without unleashing the power of SMEs,” said Michele Bongiovanni, Founder and Co-Chair of IDTSME and CEO of HealRWorld. “Our planet is on fire—literally and economically. Unlocking capital for sustainable SMEs is not optional; it’s urgent.”

A Blueprint for Financial Transformation

The Whitepaper arrives amid a steep decline in global impact investment flows, which fell by $33 billion (a 28% drop) in 2024. The taskforce argues that empowering sustainable SMEs isn’t philanthropy but “one of the most powerful economic and climate resilience strategies available,” said Co-Chair Matt Helgeson, a former Fortune 500 Chief Sustainability Officer.

To address systemic barriers, the report proposes AI-driven fintech tools, standardized impact disclosure frameworks, and regional innovation labs to incubate sustainable SMEs. These mechanisms aim to make SME finance more transparent, scalable, and aligned with global sustainability standards such as the CSRD and ISSB frameworks.

Proof in the Numbers: The Case for Sustainable SMEs

The report challenges outdated investor assumptions about SME risk. Research by HealRWorld and Federated Hermes shows that firms with strong ESG credentials consistently exhibit tighter credit spreads and greater resilience. This reinforces the economic logic for integrating sustainability into SME valuation models rather than treating it as a regulatory burden.

Digital tools like Mastercard’s Digital Doors® and HealRWorld’s SPEC® and SDID frameworks are helping small firms digitize sustainability data, making it easier for them to access procurement and impact finance opportunities.

Africa Leads by Example

The Africa Impact Scale-Up Program, chaired by Her Excellency Ramatoulaye Diallo NDIAYE, is highlighted as a successful pilot. By mobilizing capital through local banks and fostering innovation ecosystems, the program demonstrates how emerging markets can drive inclusive climate finance. “Africa is not a funding gap—it is a global catalyst,” Ndiaye said.

Toward an Inclusive Impact Economy

As investors and policymakers increasingly demand detailed sustainability data, the IDTSME’s roadmap outlines six workstreams, from Sustainable Data & AI to Impact for Africa, to guide financial inclusion at scale.

With global frameworks pushing for transparent reporting and fairer access to capital, the message from Climate Week NYC was clear: Achieving a just and inclusive sustainability transition depends on giving SMEs a stronger voice in global finance.
