Organizations are increasingly expected to show measurable progress in reducing waste and managing resources responsibly. Zero Waste to Landfill (ZWL) protocol, a bespoke methodology by our India team, provides independent verification of waste management disclosures for organizations in the Indian subcontinent. It confirms that reported processes and diversion rates are applied consistently and transparently, and that performance is measured in a reliable way.

Why ZWL verification matters

Reducing the amount of waste sent to landfill minimizes environmental impact supports more focused ESG disclosures, and strengthens stakeholder confidence. Independent verification provides confidence that reported diversion rates are accurate and credible. 

Our approach

Our approach is designed to be systematic and transparent. DNV works with your team to review waste data, assess processes and confirm that diversion strategies are both effective and traceable. Using a risk-based methodology, we test the accuracy of disclosures, check supporting documentation and ensure that data management systems are reliable.

The result is a verification statement with waste diversion rate calculated using our bespoke ZWL methodology, which can be shared in sustainability reporting, corporate communications and stakeholder engagements as an achievement in environmental stewardship.

What success looks like

Through verification, organizations receive a certificate that confirms the reliability of their reported waste disclosures and diversion rates. This recognition strengthens market credibility, builds stakeholder trust, and demonstrates that sustainability commitments are being turned into measurable action.

Our tiered recognition system highlights your progress and positions you as a leader in sustainable waste management:

• Leadership (>95%) – Setting the benchmark for near-zero landfill dependency
• Pioneer (91–95%) – Embedding advanced waste strategies across operations
• Qualified (85–90%) – Building strong foundations and demonstrating tangible progress

Alongside recognition, our verification provides clarity on three critical measures:

• Total waste generated
• Waste diverted from disposal
• Waste directed to landfill or incineration

This combination of recognition and actionable insight not only validates current performance but also helps you benchmark progress, enhance reporting credibility, and showcase sustainability leadership to regulators, investors, and stakeholders year after year.
