  • Stability of alkalinity in the land-ocean transition zone: A geochemical CDR perspective for the Elbe River, Germany

    Open AccessMingyang Tian, Jens Hartmann et al.ARTICLEEnvironmental Research Letters2025

    Carbon dioxide removal (CDR) strategies like enhanced weathering and river/ocean alkalinity enhancement have been suggested to increase alkalinity in rivers, coastal areas, and eventually oceans. The effectiveness and sustainability of these CDR approaches depend on the persistence of added alkalinity, since exceeding certain Ω-thresholds for a given water composition may lead to carbonates formation, causing the loss of previously added alkalini…

  • Marine carbon dioxide removal by alkalinization should no longer be overlooked

    Open AccessKatarzyna A Kowalczyk, Thorben Amann et al.ARTICLEEnvironmental Research Letters2024

    To achieve the Paris climate target, deep emissions reductions have to be complemented with carbon dioxide removal (CDR). However, a portfolio of CDR options is necessary to reduce risks and potential negative side effects. Despite a large theoretical potential, ocean-based CDR such as ocean alkalinity enhancement (OAE) has been omitted in climate change mitigation scenarios so far. In this study, we provide a techno-economic assessment of large-…

  • Potential and costs of carbon dioxide removal by enhanced weathering of rocks

    Open AccessJessica Strefler, Thorben Amann et al.ARTICLEEnvironmental Research Letters2018

    The chemical weathering of rocks currently absorbs about 1.1 Gt CO2 a(-1) being mainly stored as bicarbonate in the ocean. An enhancement of this slow natural process could remove substantial amounts of CO2 from the atmosphere, aiming to offset some unavoidable anthropogenic emissions in order to comply with the Paris Agreement, while at the same time it may decrease ocean acidification. We provide the first comprehensive assessment of economic c…

  • Negative emissions—Part 2: Costs, potentials and side effects

    Open AccessSabine Fuss, William F Lamb et al.ARTICLEEnvironmental Research Letters2018

    The most recent IPCC assessment has shown an important role for negative emissions technologies (NETs) in limiting global warming to 2 °C cost-effectively. However, a bottom-up, systematic, reproducible, and transparent literature assessment of the different options to remove CO2 from the atmosphere is currently missing. In part 1 of this three-part review on NETs, we assemble a comprehensive set of the relevant literature so far published, focus…

  • Negative emissions—Part 1: Research landscape and synthesis

    Open AccessJan C Minx, William F Lamb et al.ARTICLEEnvironmental Research Letters2018

    With the Paris Agreement's ambition of limiting climate change to well below 2 C, negative emission technologies (NETs) have moved into the limelight of discussions in climate science and policy. Despite several assessments, the current knowledge on NETs is still diffuse and incomplete, but also growing fast. Here, we synthesize a comprehensive body of NETs literature, using scientometric tools and performing an in-depth assessment of the quantit…

  • Negative emissions—Part 3: Innovation and upscaling

    Open AccessGregory F Nemet, Max Callaghan et al.ARTICLEEnvironmental Research Letters2018

    We assess the literature on innovation and upscaling for negative emissions technologies (NETs) using a systematic and reproducible literature coding procedure. To structure our review, we employ the framework of sequential stages in the innovation process, with which we code each NETs article in innovation space. We find that while there is a growing body of innovation literature on NETs, 59% of the articles are focused on the earliest stages of…
