China’s plastic import ban increases prospects of environmental impact mitigation of plastic waste trade flow worldwide

Zongguo W. et al., Nature Communications Plastics & Pollution Shipping & Ports

Since the late 1990s, the trend of plastic waste shipment from developed to developing countries has been increasing. In 2017, China announced an unprecedented ban on its import of most plastic waste, resulting in a sharp decline in global plastic waste trade flow and changes in the treatment structure of countries, whose impacts on global environmental sustainability are enormous but yet unexamined.

Seagrasses provide a novel ecosystem service by trapping marine plastics

Anna Sanchez-Vidal et al., Scientific Reports, Nature Energy Solutions Fisheries & Aquaculture Plastics & Pollution

There is strong evidence that the seafloor constitutes a final sink for plastics from land sources. There is also evidence that part of the plastics lying on the shallow seafloor are washed up back to the shoreline. However, little is known on the natural trapping processes leading to such landwards return.

The Ocean 100: Transnational corporations in the ocean economy

Virdin, J. et al., Science Advances

Most of the revenues extracted from use of the world’s oceans is concentrated among 100 transnational corporations, which have been identified for the first time by researchers at Duke University and the Stockholm Resilience Centre at Stockholm University.

Dubbed the “Ocean 100,” these “ocean economy” companies collectively generated $1.1 trillion in revenues in 2018, according to research published Wednesday in the journal Science Advances.

Shades of blue in financing: Transforming the ocean economy with blue bonds

Joywin Mathew, DLA Piper

The annual economic value generated by our oceans is approximately USSD3 trillion, making the ocean economy, the fifth largest economy globally. However, the health of our oceans has deteriorated drastically from overfishing, marine littering, the effects of climate change and the rapid increase in the intensity and diversity in the ways we use our oceans.

The financial sector has a key role to play in supporting ocean sustainability and delivering transformative change to ocean economies.

Exposure of coastal environments to river-sourced plastic pollution

P.T. Harris et al., Science of the Total Environment - Elsevier Plastics & Pollution

Marine litter is a global problem which poses an increasing threat to ecosystem services, human health, safety and sustainable livelihoods. In order to better plan plastic pollution monitoring and clean-up activities, and to develop policies and programmes to deter and mitigate plastic pollution, information is urgently needed on the dif-ferent types of coastal ecosystem that are impacted by land-sourced plastic inputs, especially those located inproximity to river mouths where plastic waste is discharged into the ocean.

Pervasive distribution of polyester fibres in the Arctic Ocean is driven by Atlantic inputs

Peter S. Ross, et al., Nature Plastics & Pollution

Microplastics are increasingly recognized as ubiquitous global contaminants, but questions linger regarding their source, transport and fate. We document the widespread distribution of microplastics in near-surface seawater from 71 stations across the European and North American Arctic - including the North Pole.

Net Zero Carbon Cities: An Integrated Approach

Jacob Corvidae et al., World Economic Forum Energy Solutions

Cities cover 3% of the earth’s land surface yet they create more than 70% of all carbon emissions. To keep global temperature increases to 1.5°C or below, cities have to achieve net-zero. This report provides a global framework and recommends an integrated energy approach, defined as “systemic efficiency”, as a solution to the current environmental, economic, health and social crises.

The Science we need for the ocean we want: the United Nations Decade of Ocean Science for Sustainable Development (2021-2030)

Intergovernmental Oceanographic Commission/ UNESCO

On 5 December 2017, the United Nations declared that a Decade of Ocean Science for Sustainable Development would be held from 2021 to 2030. The Ocean Decade provides a common framework to ensure that ocean science can fully support countries to achieve the 2030 Agenda for Sustainable Development.

The Ocean Decade provides a ‘once in a lifetime’ opportunity to create a new foundation across the science-policy interface to strengthen the management of our oceans and coasts for the benefit of humanity.

Airborne microplastic particles detected in the remote marine atmosphere

Miri Trainic, et al., Nature Plastics & Pollution

The ubiquity of AMP from terrestrial sources, and the ubiquity of MP in the world’s oceans raise the question whether AMP are present in the remote marine atmosphere. We searched for marine AMP during the Tara Pacific expedition, a 2.5 year research project that investigates coral reefs and plankton communities.
