Independent climate policy expert specialising in Paris Agreement implementation, NDC analysis, and politically feasible mitigation pathways.
Dr. Jill Jäger is an Austrian independent climate policy researcher and sustainability scientist who operates as a private expert contributor to large international research consortia. Her core work sits at the intersection of climate mitigation analysis and science-policy translation — she helps research teams assess whether emissions reduction pathways are not only technically feasible but also politically viable and socially acceptable. In both of her H2020 projects she contributed expertise in integrated assessment of climate scenarios, national climate commitments (NDCs), and the socio-economic consequences of decarbonisation choices. She is the kind of expert brought into a consortium to ensure that modelled pathways connect to real-world governance constraints and the Sustainable Development Goals.
Both GREEN-WIN and ENGAGE centre on climate mitigation strategies, with ENGAGE specifically addressing national and global emissions reduction pathways and the Paris Agreement's global stocktake mechanism.
ENGAGE (2019–2023) lists integrated assessment as a core keyword, reflecting expertise in multi-model, multi-pathway scenario analysis used to inform IPCC and UNFCCC processes.
The ENGAGE keyword 'politically feasible' signals a distinct contribution: assessing which mitigation strategies can actually be implemented given governance and political economy constraints.
GREEN-WIN (2015–2018) focused on identifying win-win strategies where climate action and economic growth reinforce each other, connecting to the SDG agenda.
ENGAGE keywords include NDC, global stocktake, and mid-century strategies — the specific instruments of Paris Agreement implementation — suggesting growing specialisation in this area post-2019.
In her first H2020 project (GREEN-WIN, 2015–2018), Dr. Jäger's focus was on the strategic framing of climate action — identifying conditions under which climate policy and economic growth can be mutually reinforcing, a relatively conceptual and governance-oriented angle. By the time ENGAGE began in 2019, the focus had become much more operationally specific: national determined contributions, the global stocktake process under the Paris Agreement, mid-century decarbonisation strategies, and the socio-economic distributional effects of emissions reductions. This shift mirrors the broader field's pivot from "should we act on climate?" to "how exactly do we implement what was agreed in Paris?" — and Dr. Jäger appears to have moved with that frontier.
She is deepening into the technical and political mechanics of Paris Agreement implementation — a field that will remain central to EU and UNFCCC research funding through 2030 and beyond.
Dr. Jäger has participated exclusively as a non-coordinating expert in both projects, which is consistent with the profile of a senior independent scientist brought in for specific intellectual contributions rather than project management. Her two projects collectively involved 41 consortium partners across 21 countries, indicating she works within large, internationally diverse consortia — not small bilateral arrangements. This pattern suggests she is a valued specialist contributor whose role is to provide expertise that the coordinating institution cannot supply in-house.
Despite only two projects, Dr. Jäger has built a notably wide network: 41 unique partners spanning 21 countries, which is unusually broad for such a small project portfolio. This points to participation in large, well-connected international research consortia — likely ones tied to IPCC and UNFCCC scientific communities.
Dr. Jäger occupies a specific niche that few organisations can fill: an independent senior expert who bridges quantitative climate modelling (integrated assessment) and qualitative political economy analysis. Where most research groups are either modellers or governance scholars, her profile suggests she can speak both languages — making her particularly valuable in consortia that need to translate scenario outputs into policy-actionable conclusions. As an independent consultant rather than a large institution, she offers flexibility and focused senior attention that university departments or research institutes often cannot guarantee.
