“…The carbon stock of mangroves is much larger than that estimated for seagrass beds (Alongi, 2022). Indeed, seagrass carbon stocks in the uppermost 1 m of sediment range from 12 to 120 Mg C ha −1 with a median value of 69.3 Mg C ha −1 (Alongi, 2018;Miyajima et al, 2022), with sequestration rates ranging from 94 to 161 kg C ha −1 y −1 (Miyajima et al, 2022). Recently, however, Van et al (2021) found that many estimates do not account for other processes, including denitrification, sulfur, and inorganic carbon cycling.…”

Tropical marine ecosystems provide a wide range of provisioning, regulating, supporting and cultural services to millions of people. They also largely contribute to blue carbon sequestration. Mangroves, seaweeds, and seagrass habitats are important because they store large amounts of organic carbon while fish play a fundamental role in the carbon transport to deep waters. Protecting and restoring tropical marine ecosystems is of great value to society because their decline impairs the vital services they provide, such as coastal protection and seafood supplies. In this marine policy paper, we present options for enhancing blue carbon sequestration in tropical coastal areas. In addition, we outline the economic value of four components of coastal ecosystems (mangroves, seagrass beds, seaweed forests and fish) and discuss the economic levers society can apply to ensure the end of the current gross mismanagement of tropical blue carbon ecosystems. Market-based solutions, such as carbon taxes or fines for violations that use the ‘polluter pays' principle, can be very effective in achieving national or international climate agreements. Private investment can also finance the preservation of blue carbon ecosystems. One widely known financing method for blue carbon conservation, particularly of mangroves, is the use of municipal bonds, which can be issued like traditional bonds to finance the day-to-day obligations of cities, states and counties. Non-philanthropic investments can also be used in order to protect these ecosystems, such as debt-for-nature swaps and the improved application of regulatory frameworks. Overall, the protection of tropical marine ecosystems is an ecological imperative and should also be seen as an opportunity for new revenue streams and debt reduction for countries worldwide.

“…[23] craft a mosaic of geophysical constraints for Zostera marina seagrass meadows, revealing intricate patterns of organic carbon sequestration etched into the sediment of these temperate sanctuaries. Seagrasses are conductors in a symphony, orchestrating a reduction in current velocity that allows carbon to settle gently on surfaces and the seabed, creating a serene haven for carbon sequestration [24]. Others unfurl a map of seagrass blue carbon spatial patterns at the meadow scale, suggesting that larger, contiguous meadows become expansive canvases holding the brushstrokes of blue carbon in their intricate designs [25].…”

Coastal ecosystems, especially mangroves and seagrass beds, play a crucial role in maintaining the balance and sustainability of coastal ecosystems. Besides being a natural bulwark against storms and ocean waves, mangroves are unique in their ability to absorb and store carbon dioxide in their biomass and mud soil. Meanwhile, seagrass beds support the sustainability of coastal ecosystems and act as sinks for substantial marine carbon. Logging or damaging these ecosystems can result in massive releases of carbon, exacerbating climate change. Therefore, the conservation and restoration of mangroves and seagrass beds through research methods and sustainable policy implementation is essential to maintain global environmental sustainability and mitigate the impacts of climate change.

“…The restored and now matured Zostera marina ‐dominated seagrass meadows in the Baltic Sea sequester carbon at a mature rate of 39.4 g C/m 2 /yr (averaged from Greiner et al., 2013; Marbà et al., 2015; Prentice et al., 2020). The carbon sequestration in the North Sea is slightly less with 24 g C/m 2 /yr for Zostera noltei ‐dominated meadows (averaged and adjusted from Alongi & Alongi, 2018; Postlethwaite et al., 2018; Prentice et al., 2020). Today, the total area of seagrass along the German coastlines (Baltic and North Sea) sequesters approximately up to 454 kt CO 2 /yr.…”

Net‐Zero CO₂ Germany—A Retrospect From the Year 2050

Let's take a look at a possible future Germany that has reached its net-zero CO 2 emissions goal by 2050. What are the measures that have contributed to reaching this net-zero system? And what kind of implementation efforts are associated with this portfolio of measures?In this perspective, we outline how a carbon-neutral system for Germany in 2050 could look like, following three strategies of avoiding, reducing, and removing CO 2 emissions. We envision a net-zero-2050 Germany by combining analysis from an energy system model with insights into approaches that allow for a higher carbon circularity in the German system, and first results from assessments of national carbon dioxide removal (CDR) potentials.
