Sustainable packaging accreditations

Sustainable packaging certifications

If you are responsible for either sustainability, packaging, or both at your business, you will know how vital sustainable packaging certifications can be.

Sustainable packaging certifications include FSC, ISO 14001 and 9001, EcoVadis, and the use of OPRL (On Pack Recycling Label) symbols. Achieving certification or being part of such schemes holds businesses accountable and provides standardised methods of measuring sustainability. Using appropriate logos and branding on your packaging conveys the environmental benefits to your customers.

As such, by working with us at GWP you can source your packaging from a company with extensive sustainable packaging accreditations. Doing so helps you achieve your sustainability goals and targets.

FSC® certified packaging

GWP Packaging achieved Forest Stewardship Council® (FSC®) Chain of Custody certification (Certificate no. FSC – C161914) in December 2020.

It means your business can source FSC-certified transit packaging, eCommerce boxes and point-of-sale displays from us. It also grants you the right to use the FSC logo on any fully FSC-certified packaging.

Chain of Custody certification

FSC chain of custody certification verifies that FSC-certified material is identified and separated from non-certified and non-controlled material. It covers all touchpoints as it makes its way along the supply chain, from the forest to the market.

GWP is fully audited to the FSC-STD-40-004 Chain of Custody standard to maintain this certification.

More about the FSC®

More than 25 years ago, the 1992 Earth Summit in Rio failed to produce an agreement to stop deforestation. But it led to the formation of a committed group of businesses, environmentalists and community leaders. The result was a revolutionary concept, a voluntary, market-based approach that would improve forestry practices worldwide.

That meeting marked the birth of the Forest Stewardship Council. The organisation has since pioneered certification for sustainable forestry. It remains the most trusted sustainable forest management solution thanks to committed and diverse stakeholders.

FSC certified packaging
All of the corrugated cardboard packaging that GWP manufactures is FSC certified by default.

The Forest Stewardship Council has certified approximately 213 million hectares of forests worldwide. Certified forests now account for 11 per cent of all productive forests globally. Around 40 per cent of the UK’s forests are certified by the FSC. WWF, Greenpeace and The Woodland Trust, amongst many others, are prominent supporters.

ISO 14001 packaging manufacturers

GWP aims to minimise our operational impact on the environment and is committed to reducing greenhouse gas (‘GHG’) emissions.

The figures from the emissions report provide several opportunities where GWP can continue to minimise emissions and environmental impact.

GWP Group hold the ISO 14001 accreditation for commitment to the environment.

This family of standards relates to the environmental management of the whole business. It enables us to minimise operational impact on the environment. It also aids compliance with applicable laws and regulations and fosters a culture of continual improvement.

ISO 14001

About ISO 14001

ISO 14001 is very similar in structure to the ISO 9001 quality management accreditation. Both relate to internal process management rather than the end product.

However, the requirements of ISO 14001 also form an integral part of the European Union’s environmental management scheme (EMAS).

Ultimately, the standard provides a structure for GWP’s drive towards continuous improvement in managing the company’s environmental responsibilities.

ISO 9001:2015 Accreditation

Besides ISO 14001, GWP is proud to hold ISO 9001:2015 accreditation.

ISO 9001 is effectively a quality management standard. It is crucial in driving a fully integrated quality management system throughout the company.

It puts beyond question our ability to consistently provide packaging products and services that meet customer and regulatory requirements. It provides a solid building block towards the ultimate goal of absolute customer satisfaction.
