Nature is a foundation of our work and a constant source of inspiration.
Our commitment
Caring for nature means integrating environmental responsibility into the way we operate, through actions that are measured, documented, and continuously improved.
As a company working with precious materials, NIRU recognises the responsibility that comes with sourcing, transforming, and preserving natural resources. Protecting ecosystems and supporting the communities connected to our operations are part of this commitment.
Our approach covers climate action, renewable energy, responsible water management, waste reduction, and biodiversity protection.
2025. The Thailand manufacture achieved ISO 14001:2015 certification, followed by Sri Lanka in early 2026.
Climate & Carbon
The group's carbon footprint has been measured across Scopes 1, 2, and 3 by Environmental Resources Management since 2021. Reporting covers both direct operations and value-chain emissions, with achievements and targets clearly distinguished.

2025Materials and ecosystems
Across NIRU’s operations, we are committed to extending material use and optimizing recycling to minimize disposal, while addressing ecosystem impacts throughout our supply chain.
Goal 01 · Waste, awareness
Improving resource efficiency through reduction, recovery, and the gradual transition away from plastic packaging across Sri Lanka and Thailand operations.
Goal 02 · Nature Roadmap
In 2024, the group initiated its Nature Roadmap, aligned with the Watch & Jewellery Initiative 2030 Nature Pillar and the ACT-D framework, to assess and manage its impacts and dependencies on natural ecosystems.
The roadmap · four stages
Supply chain impacts and dependencies analysis.
Local site biodiversity and water assessment.
Nature risks and opportunities evaluation.
Nature strategy and action plan development.
Roadmap · the nature path
Committed to our near-term targets, NIRU is also looking beyond them. Our clear pathway forward focuses on continuously evolving and improving our operations and value chain, for the nature we all share.
People and product ethics. Each area carries its own record.
