GreenLight Biosciences Announces Close of Additional Financing

Just Climate’s $25 Million Investment Supports Global Expansion and Commercialization of Breakthrough RNA Technology

BOSTON, MA and LONDON, UK, March 26, 2025 — GreenLight Biosciences, Inc. (“GreenLight Bio”), a leader in next generation biosolutions for agriculture, announced the successful close of its Series C funding round, including a $25 million investment from new investor, Just Climate, a mission-driven investor in high impact climate solutions, and support from other new and existing shareholders. This investment validates GreenLight Bio’s innovative approach to developing sustainable solutions that enhance agricultural productivity while preserving biodiversity.

The new capital supports GreenLight Bio’s commercial momentum following the successful launch of Calantha™, which is registered in the United States and Ukraine. It is the first-ever-registered RNA-based crop protection spray. Calantha™ has demonstrated remarkable efficacy, offering potato growers a safe, easy to use, and environmentally responsible alternative to conventional chemical pesticides.

"This strategic investment from Just Climate and others represents a powerful endorsement of our RNA platform’s potential to revolutionize agriculture while addressing environmental challenges including pollinator health," said Dr. Andrey Zarur, CEO of GreenLight Bio. "With this funding, we are well-positioned to scale our commercial operations, advance our product pipeline, expand our international footprint, and further our mission of building a safer, more equitable food system using nature."

The funding will also help drive several other strategic developments:

Product Pipeline Advancement

Once registered in the US, GreenLight Bio will quickly move to commercialize Norroa™, a powerful new tool for beekeepers to protect their colonies from varroa mites. This innovation comes at a critical moment as beekeepers reported catastrophic honeybee colony losses averaging 62% between June 2024 and February 2025, according to recent Honey Bee Health Coalition data. The company will also further internationalize Fortivance™, a novel adjuvant that enhances the efficiency of existing agricultural treatments and can reduce their environmental impact.

Global Expansion

The investment enables the company to continue its expansion across key international markets, including Brazil and other Latin American countries. Recent expansion efforts include the establishment of a state-of-the-art Agricultural Research Station in Seville, Spain, which now serves as the Company’s European hub for innovation and collaborative research in sustainable agriculture practices.

Sustainability Leadership

GreenLight Bio will strengthen its position as a leader in agricultural sustainability, pioneering solutions that offer farmers an alternative to conventional chemical pesticides, minimizing environmental impact while maintaining food production and supporting biodiversity.

“GreenLight Biosciences exemplifies the type of innovative enterprise that can deliver transformative environmental impact while building sustainable commercial success,” said Eduardo Mufarej, head of the Natural Climate Solutions strategy and co-Chief Investment Officer at Just Climate. “Their platform addresses some of the most pressing challenges facing global agriculture and biodiversity conservation. We are pleased to support GreenLight Bio’s mission and solutions that help protect crops, pollinators, and our planet’s ecosystems.”
