Norway’s Plastic Pollution Challenge
Despite numerous initiatives to combat marine plastic pollution in Norway, a groundbreaking study reveals that only a handful of measures will lead to substantial environmental improvement. Every year, millions of tons of plastic waste enter our oceans, creating what experts describe as a rapidly escalating ecological crisis that demands immediate systemic change. As researchers from the Norwegian University of Science and Technology (NTNU) investigate this pressing issue, they emphasize that current approaches largely focus on cleanup rather than prevention. This aligns with growing global recognition that marine plastic pollution solutions require fundamental shifts in how we produce and consume materials.
“The solutions we have today mostly concern cleanup after we’re done with the plastic,” explains Natalya Amirova, Ph.D. research fellow at NTNU’s Department of Psychology. “We sort, we recycle and we pick up plastic on the shore. But what about approaches that completely change the way we produce and consume plastic?” Amirova is part of an interdisciplinary research team working to identify the main sources and solutions for plastic pollution in Norwegian marine environments, recognizing that technological solutions alone cannot solve this complex problem.
Comprehensive Analysis of 50+ Measures
The research team examined over 52 Norwegian measures implemented since the 1980s, ranging from practical cleanup efforts to broader policy initiatives. These include annual beach clean-ups, retrieval of abandoned fishing gear from seabeds, microplastic filtration systems in wastewater treatment plants, and the development of biodegradable fishing materials. The team also evaluated information campaigns, improved sorting systems, and digital mapping services for locating lost fishing equipment. This comprehensive review mirrors the systematic approach needed when evaluating complex technological systems, where multiple factors must be considered simultaneously.
Project coordinator Siv Marina Flø Grimstad, associate professor at the NTNU School of International Business in Ålesund, underscores the urgency: “Marine plastic litter is a huge problem for the marine ecosystem. So far, we lack good solutions to stop this flow of plastic going astray.” The research reveals that most current approaches rely heavily on recycling, beach cleaning, microplastic removal, and alternative materials without addressing the root causes of plastic pollution.
Three Transformative Approaches Identified
Among the more than 50 measures analyzed, only three demonstrated potential for creating profound systemic change:
- The municipal network KIMO (International Organization of Local Authorities) emphasizing political equality and environmental protection
- The Government’s strategy for a circular economy motivated by ecological sustainability
- International Ocean Panel promoting responsible ocean management
These approaches share a common emphasis on pro-social and pro-ecological values that prioritize environmental health, human welfare, and community well-being over purely economic considerations. This represents a significant departure from traditional environmental management, similar to how fundamental system changes require rethinking established paradigms and support structures.
Limitations in Current Approaches
Despite their potential, the researchers identified critical limitations in these transformative measures. All three lack clearly defined goals and implementation timelines, making it difficult to assess their actual impact on reducing plastic pollution. Additionally, the Ocean Panel and circular economy strategy still incorporate external values that prioritize economic prosperity over ocean health.
“The Ocean Panel and the Government’s strategy for a green circular economy are characterized by external values, meaning values motivated by rewards, recognition or goals outside the activity itself, where they prioritize economic prosperity over the health of the oceans,” Amirova explains. This tension between economic and ecological priorities represents a fundamental challenge in environmental policy, not unlike the complex balancing acts required when developing revolutionary materials and technologies.
The Psychology of Value Systems
The research delves deeply into how different value systems influence environmental behavior. “Societal materialistic values include financial success, status and economic growth,” Amirova notes. “At the other end of the value spectrum, we have intrinsic values, such as social equality, environmental and human health and well-being, art and creativity.”
Research by American psychologist Tim Kasser demonstrates that exposure to materialistic values leads people to prioritize behaviors associated with those values while opting out of actions that benefit society and the environment. “Kasser says societal changes can only occur when decision-makers at different levels of society are exposed to and act in line with pro-social and pro-ecological values, rather than materialistic values and goals,” Amirova emphasizes. This psychological dimension is as crucial as understanding the complex economic factors that drive systemic change in other domains.
Environmental Messaging and Perception
The study highlights how environmental messaging shapes public perception and behavior. “Today, social media in particular, with news and advertisements, helps determine how we behave on a daily basis. This also applies to how we view the sea,” Amirova observes. When media portrays the ocean primarily as an economic resource—”the world’s seventh largest economy”—it reinforces materialistic perspectives that undermine conservation efforts.
“But the ocean is not just about money,” Amirova counters. “It also contributes to our physical and mental health. There are social and ecological values associated with the ocean. When we make decisions, we should keep this in mind and not perceive the ocean solely as a commodity.” This shift in perspective requires rethinking how we measure progress, similar to how advanced computing requires developing new metrics beyond traditional performance indicators.
Proposed Solutions for Systemic Change
The study, published in PLOS Sustainability and Transformation, proposes several concrete strategies for strengthening ocean conservation efforts:
- Replace economic indicators with ocean health metrics (water quality, biodiversity) as primary progress measures
- Establish clear goals and timelines for plastic waste reduction early in the value chain
- Increase support for grassroots initiatives and small-scale businesses with “zero waste” profiles
- Reduce profit-based advertising in favor of non-profit environmental messaging
- Promote less materialistic societies with more circular lifestyles
These recommendations emphasize three key concepts: relational environmental thinking (recognizing the interconnected relationship between humans and nature), circular economy principles, and ocean stewardship. Supporting local zero-waste initiatives can simultaneously reduce plastic consumption and strengthen communities, creating multiple benefits that extend beyond environmental protection. This comprehensive approach resembles the multidisciplinary coordination required for successful scientific missions and technological innovations.
The Sweet Spot Project: Interdisciplinary Solutions
The research is part of the broader Sweet Spot project, an interdisciplinary collaboration identifying key sources and hotspots of plastic pollution in Norwegian waters. The project combines machine learning, artificial intelligence, laboratory analyses, behavioral science, supply chain management, and business model innovation to develop lasting solutions.
Six doctoral researchers are developing new methods for detecting and managing marine litter, including unmanned autonomous vehicles for data collection, laboratory experiments measuring plastic degradation rates, and analysis of microplastic pollution in beach sand. The project also includes organizational network analysis in plastic-based fishing gear value chains, development of new business models for fishing gear manufacturers, and identification of key parameters for effective behavior change at individual and group levels.

Grimstad emphasizes the critical importance of this work: “If we are to have any hope of improving the situation and avoiding having more plastic than fish in the world’s oceans in 2050, as many predict, we must have a change of attitude all the way down to the individual level. This in turn has to lead to behavioral changes, which is what Natalya is focused on.” The project represents a comprehensive approach to one of our most pressing environmental challenges, recognizing that only through fundamental changes in production and consumption patterns can we hope to achieve plastic-free oceans.
