New life cycle assessment reveals U.S. fishery outperforms beef, pork, and chicken in environmental efficiency.

SEATTLE, Washington — The Association of Genuine Alaska Pollock Producers (GAPP) has officially released the findings of its second comprehensive life cycle assessment (LCA), confirming that Wild Alaska Pollock remains one of the most climate-friendly proteins on the planet.

The 2024 study, conducted by researchers from Dalhousie University, tracked nine distinct environmental impact categories, including greenhouse gas emissions, energy resource use, and acidification potential. The data reveals a significant trend in sustainability: greenhouse gas emissions for Wild Alaska Pollock products have dropped by 16.7% since the previous assessment in 2021.

Unmatched Efficiency in the Protein Market

When compared to land-based livestock, the environmental advantages of the U.S. Alaska Pollock fishery are stark. The study found that Wild Alaska Pollock fillets produce only 3.41 kg CO2-eq per kg of protein.

To put this into perspective, the carbon impact of this fishery is:

  • 27% of the impact of chicken.

  • 16% of the impact of pork.

  • Less than 3% of the impact of beef.

“This study confirms that Wild Alaska Pollock is the right protein choice for consumers who seek to lower their environmental footprint through their dietary choices,” said GAPP Chairman Jim Johnson. “All of us who harvest and process Wild Alaska Pollock are extremely proud that in addition to the sustainable and responsible management of the resource and our products’ healthfulness and affordability, the low carbon emissions are yet another reason for consumers around the world to increase their consumption of Wild Alaska Pollock.”

Rigorous Scientific Validation

The research was led by Dr. Peter Tyedmers, a professor at Dalhousie University’s School for Resource and Environmental Studies, alongside Master’s student Michelle Mann. The team analyzed the entire production chain for various products, including fillets, surimi, roe, minced fish, fish meal, and fish oil.

Dr. Tyedmers, a global authority on seafood environmental performance, noted the exceptional nature of these findings.

“I have been studying the energy efficiency of food production for close to 30 years and the results of this study remind us that harvesting and processing of Alaska pollock from US waters is one of the most energy-efficient and climate friendly methods of producing high quality animal protein for human consumption I have analyzed,” said Dr. Tyedmers.

The study's success relied on unprecedented transparency from the industry. Ms. Mann emphasized the quality of the data:

“I am extremely grateful for the responsiveness of the industry in providing the data needed to complete this study. It enabled us to conduct a very robust analysis with a high level of confidence in the results."

This new data reinforces the U.S. Alaska Pollock industry's commitment to transparency as it sets a global benchmark for sustainable food production in 2024.

天然アラスカスケトウダラが炭素排出量を約17%削減

新たなライフサイクルアセスメントにより、米国漁業が環境効率において牛肉、豚肉、鶏肉を凌駕していることが判明。

ワシントン州シアトル — 天然アラスカスケトウダラ生産者協会(GAPP)は、第2回包括的ライフサイクルアセスメント(LCA)の結果を正式に発表し、天然アラスカスケトウダラが地球上で最も気候変動に配慮したタンパク質の一つであることを改めて裏付けました。

ダルハウジー大学の研究者によって実施された2024年のこの調査では、温室効果ガス排出量、エネルギー資源利用、海洋酸性化の可能性を含む9つの異なる環境影響カテゴリーを追跡しました。そのデータは持続可能性における重要な傾向を明らかにしています。天然アラスカスケトウダラ製品に関連する温室効果ガス排出量は、2021年の前回調査から16.7%減少しました。

タンパク質市場における比類なき効率性

陸上の家畜と比較すると、米国アラスカスケトウダラ漁業の環境的優位性は際立っています。調査の結果、天然アラスカスケトウダラのフィレは、タンパク質1kgあたりわずか3.41 kg CO2-eqしか排出しないことがわかりました。

この数値を比較すると、この漁業の炭素影響は以下の通りとなります:

  • 鶏肉の影響の27%

  • 豚肉の影響の16%

  • 牛肉の影響の3%未満

「この研究は、食事の選択を通じて環境への負荷を減らそうとする消費者にとって、天然アラスカスケトウダラが正しいタンパク質の選択であることを裏付けています」と、GAPP会長のジム・ジョンソン氏は述べています。「天然アラスカスケトウダラを収穫・加工する私たち全員は、資源の持続可能かつ責任ある管理、そして製品の健康面や手頃な価格に加え、低炭素排出が世界中の消費者が天然アラスカスケトウダラの消費を増やすべきもう一つの理由であることを非常に誇りに思っています。」

厳格な科学的検証

この研究は、シーフードシステムのエネルギーおよび関連する環境パフォーマンスの世界的権威であるダルハウジー大学資源環境学部ピーター・タイドマーズ教授と、修士課程の学生であるミシェル・マン氏によって主導されました。チームは、フィレすり身魚卵ミンチ魚粉魚油を含む様々な製品の全生産チェーンを分析しました。

タイドマーズ博士は、これらの知見が極めて例外的であることを指摘しました。

「私は30年近く食品生産のエネルギー効率を研究してきましたが、この研究結果は、米国海域でのアラスカスケトウダラの収穫と加工が、私が分析した中で、人間が消費するための高品質な動物性タンパク質を生産する最もエネルギー効率が高く、気候に優しい方法の一つであることを再認識させてくれました」とタイドマーズ博士は語りました。

この研究の成功は、業界からの前例のない透明性に支えられました。マン氏はデータの質を強調しました。

「この研究を完了するために必要なデータを提供してくれた業界の迅速な対応に非常に感謝しています。これにより、結果に対して高い信頼性を持った非常に堅牢な分析を行うことができました。」

この新しいデータは、2024年における持続可能な食品生産の世界的ベンチマークを設定する米国アラスカスケトウダラ業界の透明性への取り組みを強化するものです。

野生阿拉斯加狭鳕碳足迹削减近 17%

新的生命周期评估显示,美国渔业在环境效率方面优于牛肉、猪肉和鸡肉。

华盛顿州西雅图真阿拉斯加狭鳕生产者协会 (GAPP) 正式公布了其第二次全面生命周期评估 (LCA) 的结果,证实野生阿拉斯加狭鳕仍然是地球上对气候最友好的蛋白质之一。

这项由达尔豪斯大学研究人员进行的 2024 年研究追踪了九个不同的环境影响类别,包括温室气体排放、能源资源利用和酸化潜力。数据揭示了可持续发展方面的显著趋势:自 2021 年的上一次评估以来,野生阿拉斯加狭鳕产品的温室气体排放量下降了 16.7%

蛋白质市场中无与伦比的效率

与陆基牲畜相比,美国阿拉斯加狭鳕渔业的环境优势非常明显。研究发现,每公斤蛋白质的野生阿拉斯加狭鳕鱼片仅产生 3.41 kg CO2-eq

透视这些数据,该渔业的碳影响仅为:

  • 鸡肉影响的 27%

  • 猪肉影响的 16%

  • 牛肉影响的不足 3%

“这项研究证实,对于那些寻求通过饮食选择来降低环境足迹的消费者来说,野生阿拉斯加狭鳕是正确的蛋白质选择,”GAPP 主席 Jim Johnson 表示。“我们所有捕捞和加工野生阿拉斯加狭鳕的人都感到非常自豪,除了资源的持续和负责任管理以及我们产品的健康性和负担能力之外,低碳排放是世界各地消费者增加消费野生阿拉斯加狭鳕的又一理由。”

严谨的科学验证

该研究由达尔豪斯大学资源与环境研究学院Peter Tyedmers 教授(海鲜系统能源及相关环境绩效方面的全球权威)以及硕士生 Michelle Mann 领导。团队分析了各种产品的整个生产链,包括鱼片鱼糜鱼籽碎肉鱼粉鱼油

Tyedmers 博士指出,这些发现具有特殊的意义。

“我研究食品生产的能源效率已有近 30 年,这项研究的结果提醒我们,从美国海域捕捞和加工阿拉斯加狭鳕是我分析过的生产人类消费高质量动物蛋白最节能、最气候友好的方法之一,”Tyedmers 博士说。

这项研究的成功得益于行业前所未有的透明度。Mann 女士强调了数据的质量:

“我非常感谢行业在提供完成这项研究所需数据方面的积极响应。这使我们能够进行非常稳健的分析,并对结果充满信心。”

这一新数据加强了美国阿拉斯加狭鳕行业对透明度的承诺,因为它设定了 2024 年全球可持续食品生产的基准。
