[This dataset is embargoed until October 30, 2026]. This dataset comprises spatially explicit, modelled outcomes of multiple alternative pathways towards the UK Government's legally binding target of achieving Net Zero in territorial emissions by 2050. These pathways relate specifically to changes in the UK's agriculture, land use and forestry sectors that might contribute towards this target. This dataset includes UK-extent maps of changes in land use, land cover and land management under each pathway, along with modelled spatial data on a range of indicators quantifying environmental impacts on greenhouse gas abatement, soils, water and biodiversity. All data are tiff format rasters at UK extent, mostly at 1 km resolution, and show outcomes for a nominal baseline of 2024 and 3 future time slices (2030, 2042 and 2050). A variety of rule-based, process-based and statistical models were used to create these outputs. Each pathway represents a hypothetical but plausible trajectory of change for the agriculture, land use and forestry sectors, made up of multiple measures that contribute to emissions reductions and increased sequestration. The pathways are exploratory, using contrasting measures and levels of uptake. These modelled data are therefore not predictions, but instead aim to provide insight into what is plausible and probable, facilitate exploration of synergies and trade-offs between progress toward Net Zero and environmental impacts, and ultimately support decision making around viable routes for achieving policy objectives. These data were created under the Land Climate Programme (LCP), a project jointly funded by DESNZ and DEFRA and delivered by a consortium including UK Centre for Ecology & Hydrology (UKCEH), Eunomia Research and Consulting Ltd, Exeter University, the Met Office and Forest Research. The finer-resolution data were created with resources under the NERC-funded DRUID project. Full details about this dataset can be found at https://doi.org/10.5285/ca0346fc-e261-45bc-8ee4-f0df6c2ca25d
