How Earth System Models assess land-based carbon removal (AR, BECCS): carbon-cycle responses, and local climate side-effects; and how Integrated Assessment Models then asses socio-economic constraints that shape decision-ready deployment.

LANDMARC’s final policy event is taking place in Brussels on 28 November 2024. The event will focus on the policy implications of Carbon Farming (CF), Carbon Capture and Storage/Utilization (CCS/CCU) and Carbon Dioxide Removal (CDR) technologies.
This article gives an overview of the links between Earth System Models and Integrated Assessment Models (including the role of Simple Climate Models) that shape one of the main frameworks used for producing the data that feed IPCC assessments.
Rather than trying to plant as many trees as possible, research coming out of the LANDMARC project suggests that it might be better to focus on planting fewer trees and managing them well, in a way thatโs good for the underlying soil.
The first fully-coupled methane emission driven Earth system model capable of simulating the impact of anthropgenic forcing on natural environments, as well as the impact of methane emissions and mitigation strategies on air quality.
This article gives an overview of the recent advances on the interactive modelling of ice sheet dynamics in Earth System Models, and the implications for reducing the uncertainty of sea-level rise projections, especially when considering multi-centennial timescales of changes or low-likelihood high-impact scenarios.
The understanding of nature-based negative emission solutions often focuses on their mitigation potential, thus as means for reaching carbon neutrality by 2050. However, this is only one small part of the whole picture; these techniques represent a more sustainable model that brings many environmental benefits in the long term.
In this article, we provide an overview of current understanding of the land-to-ocean carbon fluxes. We describe the new conceptual model of the land-to-ocean aquatic continuum (proposed by Regnier et al, 2022, Nature), as well as ongoing work to include this new knowledge in Earth System Models.
The latest ZERO IN report from the CONSTRAIN project dives into the science set out in the recent Intergovernmental Panel on Climate Change assessments. It investigates what our climate future could look like by 2050, depending on whether we take action in line with the Paris Agreement, or decide to follow current national policies and plans which still largely lack the action and ambition needed to stop global warming.
This briefing explores the questions raised during the first ESM2025 policy forum and details the contribution of ESM2025 to various policy-relevant topics.
