Growth rate analysis indicates IPCC 2100 storage targets are achievable, however tradeoffs exist between CO2 storage resource requirements, storage growth rate, and growth duration, with a ceiling on required storage resources of 2700 Gt.

Injection Rates

As a part of climate change mitigation plans in Europe, CO2 storage scenarios have been reported for the United Kingdom and the European Union with injection rates reaching 75 – 330 MtCO2 yr-1 by 2050. However, these plans are not constrained by geological properties or growth rates with precedent in the hydrocarbon industry. We use logistic models to identify growth trajectories and the associated storage resource base consistent with European targets. All of the targets represent ambitious growth, requiring average annual growth in injection rates of 9% – 15% from 2030-2050. Modelled plans are not constrained by CO2 storage availability and can be accommodated by the resources of offshore UK or Norway alone. Only if the resource base is significantly less, around 10% of current estimates, does storage availability limit mitigation plans. We further demonstrate the use of the models to define 2050 rate targets within conservative bounds of both growth rate and storage resource needs.

<p>To limit global warming to well below 2<sup>o</sup>C, integrated assessment models have projected that gigaton-per-year-scale carbon capture and storage is needed by c. 2050. These scenarios are unconstrained by limiting growth rates or historical data due to the limited existing deployment of the technology. A new approach using logistic growth models identifies a coupling between storage resource base (pore space underground) and minimum growth rates necessary to meet global climate change mitigation targets (Zahasky & Krevor, 2020). However, viable growth trajectories consistent with carbon storage targets remain unexplored at the regional level. Here, we show the application of logistic modelling constrained by climate change targets and assessed storage resources for the European Union (EU), the United Kingdom (UK), and Norway. This allows us to identify plausible growth trajectories of CCS development and the associated discovered storage resource base requirement in these regions. We find that the EU storage resource base is sufficient to meet storage targets of 80 MtCO<sub>2</sub>/year and 92 MtCO<sub>2</sub>/year suggested in the European Commission climate change mitigation strategy to 2050, ‘A Clean Planet for All’. However, the more ambitious goals of 298 MtCO<sub>2</sub>/year and 330 MtCO<sub>2</sub>/year are likely to require additional storage resources based predominantly in the North Sea. Results for the UK indicate that all anticipated storage targets to achieve net-zero economy are achievable, requiring no more than 42 Gt of the storage resource base for the most ambitious target. Furthermore, the UK and the Norwegian North Sea may be able to serve as a regional CO<sub>2</sub> storage hub. There are sufficient storage resources to support combined storage targets from the EU and the UK. The tools used here demonstrate a practical approach for regional stakeholders to monitor carbon storage progress towards future stated carbon abatements goals, as well as to evaluate future storage resource needs.</p><p>Zahasky, C., & Krevor, S.

North Sulawesi is one of the provinces that implements national / regional action plan (RAN / RAD) policies as part of a national effort to climate change mitigation. One of the land-based mitigation activities in North Sulawesi is to measure and monitore  biomass and carbon stocks in forests including coastal forests where the measurement area is still limited. In 2013-2015, Blue Carbon Research Group  conducted research in four locations in North Sulawesi, which aims to analyze the ecological conditions and the ability of coastal ecosystems, especially mangrove in sequestering carbon. Study sites situated in Ratatotok - Southeast Minahasa Regency, Kema - North Minahasa Regency, Lembeh Island – Bitung City and Sangihe Island – Sangihe Regency. A total of 17 species identified where B. gymnorrhiza, R. mucronata and S. alba found in all locations. Species diversity ranges from low to moderate, where species distribution is uneven. Carbon storage capacity is equal to 343.85 Mg C ha-1 in Ratatotok, 254,35 Mg C ha-1 in Lembeh, 387,95 Mg C ha-1 in Kema and 594,83 Mg C ha-1 in Sangihe. More than 59% of carbon storage are in the sediment. The average value of carbon storage in the four research sites is 456,86 Mg C ha-1 or 5,70 Tg C after converted to a total area of mangrove ecosystems in North Sulawesi. The value is equal to absorption of atmospheric CO2 by 20.70 Tg CO2e. Potential emission due to changes in mangrove conversion reach 0.42 Tg CO2e. Efforts to increase the contribution of reducing North Sulawesi emissions can be achieved by implementing emission reduction interventions through the rehabilitation and conservation of mangrove ecosystems.

AbstractThe conservation of ecosystems and their biodiversity has numerous co-benefits, both for local societies and for humankind worldwide. While the co-benefit of climate change mitigation through so called blue carbon storage in coastal ecosystems has raised increasing interest in mangroves, the relevance of multifaceted biodiversity as a driver of carbon storage remains unclear. Sediment salinity, taxonomic diversity, functional diversity and functional distinctiveness together explain 69%, 69%, 27% and 61% of the variation in above- and belowground plant biomass carbon, sediment organic carbon and total ecosystem carbon storage, respectively, in the Sundarbans Reserved Forest. Functional distinctiveness had the strongest explanatory power for carbon storage, indicating that blue carbon in mangroves is driven by the functional composition of diverse tree assemblages. Protecting and restoring mangrove biodiversity with site-specific dominant species and other species of contrasting functional traits would have the co-benefit of maximizing their capacity for climate change mitigation through increased carbon storage.
