Forskningsöversikt (refereegranskat)abstract
- The plastic industry is dependent on fossil fuels in various ways that result in strong “carbon lock-in” throughout the value chain and large and growing CO2 emissions. The industry must decarbonize to reach global net-zero pledges. Although a few initiatives have been launched, they primarily focus on plastic waste. Current research has investigated mitigation potential on different parts of the plastic value chain but remains in silos. Here, we review carbon lock-ins throughout the plastic value chain and identify possible mitigation pathways for each stage of the plastic life cycle. We show how lock-ins are stubbornly entrenched across the domains of production, markets, waste management, industry organization, and governance. Overcoming these carbon lock-ins and achieving zero-carbon targets for the sector by 2050 will require thorough systemic change to how plastics are produced, used, and recycled, including promotion of demand reduction strategies, bio-based feedstocks, and circular economy principles. Strict governance structures, enforceable regulation, and a new proactive and inclusive vision for the low-carbon transition are equally important.

A renaissance for lithium-sulfur batteries through low-cost, efficient, and sustainable biomass cathodes
- 2022
-
Ingår i: One Earth. - : Elsevier. - 2590-3330 .- 2590-3322. ; 5:3, s. 224-226

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Although lithium-ion batteries face material sustainability issues, one promising alternative-lithium-sulfur (Li-S) batteries-suffers from destructive chemical reactions. Recently in Chem, Hou et al. proposed one viable solution: an encapsulating lithium polysulfide electrolyte. We discuss this advance and the potential role of biomass as an alternative sustainable material for Li-S battery cathodes.

Understanding and addressing the planetary crisis of chemicals and plastics
- 2022
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 5:10, s. 1070-1074
-
Tidskriftsartikel (refereegranskat)abstract
- Planetary functions are destabilized by the releases of large quantities and numbers of anthropogenic chemicals, which go beyond planetary boundaries and threaten the safe operating space for humanity. Here, we call for urgent action to mitigate these threats and identify opportunities for intervention along the impact pathway of anthropogenic chemicals, including plastics.

Migration and the 2030 Agenda
- 2022
-
Ingår i: One Earth. - : Elsevier. - 2590-3330 .- 2590-3322. ; 5:8, s. 838-840

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The migration of people poses many challenges but also opportunities and has strong implications for the success and delivery of the Sustainable Development Goals (SDGs). Conversely, the 2030 Agenda consti-tutes a vital opportunity to improve migrants' lives. This Voices asks: how should migration be integrated into, and actioned within, the SDG framework to maximize positive, and minimize negative, outcomes?

Voluntary commitments made by the world’s largest companies focus on recycling and packaging over other actions to address the plastics crisis
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Plastic pollution has caused significant environmental and health challenges. Corporations that contribute to the manufacture, use, and distribution of plastics can play a vital role in addressing global plastic pollution and many are committing to voluntary pledges. However, the extent to which corporations’ voluntary commitments are helping solve the problem remains underexplored. Here, we develop a novel typology to characterize voluntary commitments to reduce plastic pollution made between 2015 and 2020 by 973 companies, including the top 300 of the Fortune Global 500. We find that 72% of these companies have made some form of commitment(s) to reduce plastic pollution. About 67% of companies participating in voluntary environmental programs (VEPs) and 17% of non-VEP participants made measurable and timebound commitments. However, rather than tackle virgin plastics, most companies target packaging and general plastics and frequently emphasize recycling-related efforts. Growing commitments on plastic pollution are made by large and important companies, but significantly more efforts beyond plastic recycling are required to effectively address plastic pollution challenges.

An applied research agenda for navigating diverse livelihood challenges in rural coastal communities in the tropics
- 2022
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 5:11, s. 1205-1215

Tidskriftsartikel (refereegranskat)abstract
- Rural, tropical coastal communities are experiencing sustained, often increasing food insecurity, poverty, and global change impacts. These challenges have stimulated a rise in projects aiming to enhance and diversify local livelihoods. The ability of these projects to achieve broad-scale benefits is limited by approaches that do not account for feedbacks among sectors and across marine and terrestrial environments. To address these limitations, we present an applied research agenda to support an integrated approach to livelihood project planning and management. This agenda explicitly examines interactions among natural resources, industries, and livelihoods and is based on three foundational activities: (1) a governance review and assessment, (2) strategic partnership formation, and (3) a diagnostic approach supported by science and shared outcomes. We add structure to the established logic in our field by broadening the sectoral and spatial scope of livelihoods projects, so they can better contribute to interrelated UN Sustainable Development Goals.

Global environmental governance in times of turbulence

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- 50 years might not seem long in the history of planet Earth, but the last 50 years have had profound implications for our living planet. 2022 marks the 50th anniversaries of the United Nations Environment Programme and the historic 1972 United Nations Conference on the Human Environment. These anniversaries invite us all to reflect on the successes and failures of collective action and global environmental governance.

No net loss of biodiversity, green growth, and the need to address drivers
- 2022
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 5:6, s. 612-614

Tidskriftsartikel (refereegranskat)abstract
- Biodiversity offsets and no net loss (NNL) are important tools for the international policy focus on ecological restoration. In this issue of One Earth, Kajula et al. call for national, public offset registers to enable evaluations of biodiversity offset programs. Here, we argue that we also need to control the main drivers of biodiversity loss.

Opportunities and barriers to net-zero cities
- 2022
-
Ingår i: One Earth. - : Elsevier. - 2590-3330 .- 2590-3322. ; 5:7, s. 739-744
-
Tidskriftsartikel (refereegranskat)abstract
- Today, more than 700 cities worldwide have made net-zero pledges. Managing these bold targets, however, is not easy given the complexity of urban systems. Although holistic mitigation efforts are vital, individual sectors are likely to face their own challenges and require tailor-made solutions. This Voices asks: what are the challenges and opportunities in transforming cities toward net-zero carbon emissions?

Ocean conservation boosts climate change mitigation and adaptation
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Marine protected areas (MPAs) are increasingly being promoted as an ocean-based climate solution. However, such claims remain controversial because of the diffuse and poorly synthesized literature on climate benefits of MPAs. To address this knowledge gap, we conducted a systematic literature review of 22,403 publications spanning 241 MPAs and analyzed these across 16 ecological and social pathways through which MPAs could contribute to climate change mitigation and adaptation. Our meta-analysis demonstrates that marine conservation can significantly enhance carbon sequestration, coastal protection, biodiversity, and the reproductive capacity of marine organisms as well as fishers’ catch and income. Most of these benefits are only achieved in fully or highly protected areas and increase with MPA age. Although MPAs alone cannot offset all climate change impacts, they are a useful tool for climate change mitigation and adaptation of social-ecological systems.
