Sustainability Certifications for Mining Companies in Spain: Key Tools for Responsible Mining

Sustainability in the Spanish mining sector is advancing steadily, supported by a range of certifications that validate best practices in environmental, social, and governance performance.

In a context where environmental impact and social responsibility are central to corporate strategy, mining companies in Spain can access various sustainability certifications that demonstrate their commitment to more ethical, efficient, and environmentally responsible operations.

Below is an overview of the main sustainability certifications available to mining companies operating in Spain:

Sustainable Mining Management Certification – UNE 22470 and UNE 22480

Specifically designed for the extractive industry, these standards developed by AENOR enable companies to assess and improve their performance across 38 indicators covering environmental, social, and economic pillars. Leading companies such as Knauf and CEMEX have already obtained this certification, positioning themselves as pioneers in sustainable mining.

ISO 14001 – Environmental Management

This internationally recognised standard supports the implementation of an effective Environmental Management System (EMS). It helps reduce ecological impact, optimise resource use, and ensure compliance with environmental legislation. It is suitable for all types of mining operations.

EMAS – EU Eco-Management and Audit Scheme

EMAS is a voluntary tool of the European Union that enables organisations to audit, report, and improve their environmental performance transparently. The certification enhances trust and reputation among regulators and stakeholders.

Zero Waste Certification

Designed for companies committed to circular economy principles, this certification verifies that all waste generated has been recovered or reused, avoiding landfilling. In mining, this involves material recovery and process efficiency.

ISO 14046 – Water Footprint

This standard assesses the environmental impact related to water usage in industrial operations. In mining, where water is a critical resource, monitoring and reducing the water footprint is essential for sustainable operations.

Global Reporting Initiative (GRI)

Though not a certification, GRI provides a standardised framework for companies to report their Environmental, Social, and Governance (ESG) performance. It is widely used by organisations seeking transparency and accountability.

Dow Jones Sustainability Indices (DJSI)

The Dow Jones Sustainability Indices rank the world’s leading companies in terms of sustainability. While primarily designed for large corporates, they serve as a clear benchmark for ESG progress in the extractive sector.

IRMA – Initiative for Responsible Mining Assurance

The IRMA certification is a voluntary international standard that comprehensively assesses the environmental, social, and governance performance of large-scale mining operations. Unlike other frameworks, IRMA is governed equally by companies, communities, workers, and civil society organisations, giving it exceptional legitimacy.

The IRMA standard covers 26 thematic areas, grouped into four core pillars:

• Business Integrity: legal compliance, ethics, financial transparency, and human rights.

• Social Responsibility: worker health and safety, community relations, and cultural heritage protection.

• Legacy Planning: mine closure planning, risk mitigation, and local benefit generation.

• Environmental Responsibility: water management, emissions, biodiversity, and mine waste.

IRMA stands out for its rigour, with more than 400 requirements assessed through independent, on-site audits. Results are made public, encouraging continuous improvement and building trust with stakeholders.

Why Sustainability Certification Matters in Mining

Adopting these certifications not only improves environmental and social performance but also:

• Builds trust with investors, regulators, and communities.

• Facilitates access to green finance and sustainable investment.

• Reduces legal, operational, and reputational risks.

• Drives innovation and operational efficiency.

At ISMC, we support the sustainable transformation of the mining sector in Spain. Promoting and facilitating access to these certifications is a key step towards building a more responsible and future-ready industry aligned with the United Nations Sustainable Development Goals (SDGs).
