Merk et al. (2021): The Need for Local Governance of Global Commons: The Example of Blue Carbon Ecosystems

Christine Merk, Jonas Grunau, Marie‐Catherine Riekhof, Wilfried Rickels IN: Kiel working paper no. 2201 | November 2021, 19 pp.

While land-based solutions, especially forests, have received a lot of attention in the past, this is not the case for ocean-based solutions. Thus in this working paper of the Kiel Institute of Economy, the focus is on different blue carbon ecosystems (BCEs), their potential for sequestering and storing carbon, and the management challenges they involve.


Hof et al. (2021): The Impact of Socio-Economic Inertia and Restrictions on Net-Negative Emissions on Cost-Effective Carbon Price Pathways

Andries F. Hof, Kaj-Ivar van der Wijst, Detlef P. van Vuuren IN: Frontiers in Climate Vol. 3,

Model-based scenarios are used to inform policymakers about emissions pathways and cost-effective carbon prices. Many of these scenarios are based on the Hotelling rule, assuming that a carbon price path increasing with the interest rate leads to a cost-effective strategy. The robustness of this rule was tested by using experiments with plausible assumptions for learning by doing, inertia in reducing emissions, and restrictions on net-negative emissions.


Nature – Park and Kug: Hysteresis of terrestrial carbon cycle to CO2 ramp-up and -down forcing

[in Review] Sowon Park, Jong-Seong Kug IN: Nature portfolio

„Herein, we show strong hysteresis in the terrestrial carbon cycle in response to CO2 ramp-up and -down forcing. Owing to the strong hysteresis lag, the terrestrial biosphere stores more carbon at the end of simulations than at its initial state, lessening the burden on net-negative emissions.“


Division of Grantham Foundation takes option to acquire stake in Ocean-Based Climate Solutions, Inc.

by Salvador Garcia

Ocean-based Climate Solutions, Inc. is pleased to announce that Neglected Climate Opportunities LLC, a division of The Grantham Foundation for the Protection of the Environment (Boston, MA), has taken an option to acquire 25% ownership upon successful demonstration of the company’s upwelling pump technology planned for July 2022 in the Canary Islands under the scientific leadership of GEOMAR Helmholtz Centre for Ocean Research Kiel.


Hanssen et al. (2021): Global implications of lignocellulosic crop-based BECCS for terrestrial vertebrate biodiversity

S. V. Hanssen, Z. J. N. Steinmann, V. Daioglou, M. Čengić, D. P. Van Vuuren, M. A. J. Huijbregts IN: GCB-Bioenergy, doi:10.1111/gcbb.12911

Here, the implications of crop-based BECCS for global terrestrial vertebrate species richness were analysed, considering both the land-use change (LUC) required for BECCS and the climate change prevented by BECCS.


Carbon Dioxide Removal Mission

At November 5 launched –  „The Carbon Dioxide Removal Mission“ was announced at COP26 with the co-leads: United States of America, Department of Energy; Kingdom of Saudi Arabia, Ministry of Energy and Canada, Natural Resources and core-mission member Norway, Gassnova. Carbon Dioxide Removal technologies should be enabled to achieve a net reduction of 100 million metric tons of CO2 per year globally by 2030.


Net Zero GHG Emissions – Where Do I Start?

by OPMMA Product Management & Marketing Association

OPMMA event where guest speaker Charles Funk provides an overview of the key concepts and consequences around reducing our carbon footprint. What does a global effort to reduce GHG mean for product managers, product marketers and other product professionals (54 min in total).


PhD Walsh Fellowship Opportunity “Quantification of Carbon fluxes from organic and organo-mineral soils”

Deadline: 5pm, Friday, 28th January 2022

The objective of the PhD will be to measure field-scale fluxes of carbon dioxide (CO2), methane (CH4) and water (H2O) and to generate land-use and land management emission factors for the following site typologies: 1. Grasslands established on shallow and deep-drained nutrient poor and nutrient rich histosols and on drained organo-mineral soils and 2. Previously drained systems which have naturally or actively been re-wetted across the full nutrient and drainage gradient. The student will be registered at Trinity College Dublin. The Fellowship provides an annual student stipend of €18,000 and full EU fees and the position is tenable for 4 years.


Nature – Riahi et al. (2021): Cost and attainability of meeting stringent climate targets without overshoot

Keywan Riahi, Christoph Bertram, Daniel Huppmann et al. IN: Nature Climate Change (2021).

A new set of net-zero CO2 emissions scenarios with limited overshoot are presented. Upfront investments are needed in the near term for limiting temperature overshoot but that these would bring long-term economic gains. The study further identifies alternative configurations of net-zero CO2 emissions systems and the roles of different sectors and regions for balancing sources and sinks.


New funding for Greenhouse Gas Removal research

Deadline: 12.00 noon, 18 January 2022

The CO2RE Hub is inviting proposals to explore new methods for capturing greenhouse gases from ambient air or the marine environment and durably storing or converting them. Projects which strategically address part of a removal method (such as capture, purification, or novel approaches to storage or conversion) will be considered, as well as full-chain methods.
