IPNLF grows its Spanish supply chain network

Conservas Emperatriz becomes the latest Member of the International Pole & Line Foundation

Ambient seafood and vegetable product supplier and brand, Conservas Emperatriz, has become the fifth Spanish-based company to join the membership network of the International Pole & Line Foundation (IPNLF), the non-profit association that is committed to developing and supporting responsible one-by-one tuna fisheries and supply chains.

Based in La Rioja, northern Spain, Conservas Emperatriz is a family-run processing company employing more than 70 workers. Since the 1960s, Conservas Emperatriz has been dedicated to the manufacture of high-quality canned fish and vegetable products sourced from Spanish fisheries and producers, keeping social and economic sustainability at the centre of all its operations. Through its own-brands, the company offers a range of high-quality, jarred tuna products, caught with one-by-one fishing practises.

Commenting on the company becoming a Member of IPNLF, Oscar de Miguel, General Director of Conservas Emperatriz says, “When we first heard about IPNLF, we realised that we must be part of this network as we share many of the same goals and ideas. We do our best to communicate the importance of preserving the health of tuna species and sustainable practises along the production chain. In our company, we work with 100% organic products, from the best of the land and the sea, to create a unique mixture of flavours and products. By collaborating with companies and organisations, we want our work to improve environmental sustainability, so future generations can experience our traditional flavours and cultures.

Adam Baske, IPNLF Director for Policy and Outreach, says, “We are delighted to connect with yet another leading company that aligns with the IPNLF vision of seeing thriving fisheries and coastal communities. We welcome Conservas Emperatriz to our growing network of supply chain Members, a company whose philosophy is centred on responsible sourcing and contributing to local communities. For more than 50 years, the company has prioritised environmental and social responsibility. This commitment includes achieving internationally recognised sustainability certification for many of its products, including its tuna, while also placing considerable importance on workplace values such as safety, job security and gender equality.”

Conservas Emperatriz joins more than 50 other supply chain stakeholder that, allied by IPNLF’s membership, are working to demonstrate the value of one-by-one caught tuna to consumers, policymakers and businesses throughout the supply chain.
