Work Location Home-based Expected duration 8 months, from 25/11/2026 to 20/07/2027 Duties and Responsibilities The United Nations Environment Programme (UNEP) is the leading global environmental authority that sets the international environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system and serves as an authoritative advocate for the global environment.
The NDC Act & Invest project is a global programme led by UNEP and currently funded by the International Climate Initiative (IKI) and the NDC Partnership’s Partnership Action Fund (PAF) multi-donor trust fund. It is designed to help countries raise their climate ambition and translate their new Nationally Determined Contributions (NDCs 3.0) submitted in 2025 into actionable, investable plans.
Structured around three interconnected workstream, fostering G20+ ambition and action, piloting policy and planning alignment, and providing deep-dive support to enhance NDC investability, the initiative aims to bridge the gap between climate commitments and tangible implementation.
By aligning national strategies, strengthening enabling environments, and working collaboratively with key partners, including the NDC Partnership, GIZ, UNDP’s Climate Promise, UNFCCC, multilateral development banks (MDBs), development finance institutions (DFIs), and private sector actors, NDC Act & Invest seeks to make the next generation of NDCs both more ambitious and more achievable, accelerating progress toward the 1.5°C goal and enhancing global resilience.
The NDC Act & Invest team, based within the Mitigation Branch in Paris, is responsible for the global management and overall coordination of the project across partner countries, in line with UNEP’s delivery model. The team also acts as the main liaison between UNEP and the NDC Partnership, coordinating UNEP’s responses to country support requests shared through the Partnership, identifying and applying for additional funding where appropriate, and consolidating implementation and progress reporting.
In addition, the team maintains close coordination with related projects under the IKI Programme to ensure coherence and synergies across initiatives. Several projects implemented under PAF and NDC Act & Invest portfolios involve a substantial quantitative modelling and technical components.
These include the development of Long-Term Low-Emission Development Strategies (LT-LEDS), which require economy-wide and sectoral emission projections to 2050, the definition of reference and mitigation scenarios and the assessment of mitigation potential and costs, as well as technical analysis of mitigation options in energy, transport and other key emitting sectors in support of NDC implementation and investment planning in partner countries, as well as the review of the technical aspects of proposals and project pipelines developed with key partner countries with NDC Act and Invest support.
Robust, transparent and consistent modelling is essential to ensure that long-term strategies and NDC implementation plans are technically credible, aligned with national GHG inventories and policy targets. UNEP therefore seeks to engage a consultant to provide technical modelling support to these projects under PAF and NDC Act & Invest.
The consultant will contribute hands-on modelling work and technical review across the supported projects, help ensure methodological consistency between country processes, contribute technical inputs to the guidance provided by UNEP to national counterparts and project teams, and assist UNEP in responding to additional modelling requests from partner countries channelled through PAF and NDC Act & Invest.
Subject to the availability of additional PAF resources, this support may be extended beyond the initial contract period.
The climate mitigation modelling consultant will: o Provide technical modelling support to the PAF and NDC Act & Invest projects implemented by UNEP, in particular the Long-Term Low-Emission Development Strategy (LT-LEDS) processes partner countries, including the development of reference and mitigation scenarios and long-term emission pathways to 2050; o Develop and review sectoral mitigation modelling in energy, transport and other key emitting sectors, including emission projections, mitigation potential, indicative costs and sensitivity analyses; o Support methodological consistency across country modelling exercises, alignment with national GHG inventories, NDC targets and IPCC methodologies, and provide technical advice to UNEP and national counterparts on data, assumptions, tools, scenario design and the treatment of uncertainty; o Support the translation of modelling results into policy-relevant outputs, including sectoral targets, costed mitigation measures and investment needs that feed into LT-LEDS, NDC implementation plans and NDC investment planning; o Review the technical aspects of proposals developed with key partner countries with UNEP support, including project pipelines, project concept notes and funding proposals, and provide structured feedback on baselines, emission reduction estimates, cost assumptions and methodologies; o Liaise, under the guidance of UNEP, with national modelling teams, consultants and partner institutions to avoid duplication and build on existing tools and datasets; o Document modelling approaches, assumptions and results, and prepare technical notes, guidance and training materials, and inputs for national counterparts, partners and donor reporting under PAF and NDC Act & Invest.
Key competencies o Advanced quantitative modelling and scenario-analysis skills; o Strong analytical ability and attention to data quality, consistency and transparency of assumptions; o Sound understanding of climate mitigation policy, NDCs and long-term strategies; o Strong technical writing skills, with the ability to document methods, assumptions and results clearly; o Ability to review modelling work produced by others and provide constructive technical feedback; o Ability to support several country processes in parallel and meet project timelines; o Ability to communicate modelling results clearly to policymakers and non-specialists.
