Climate Mitigation Modelling Consultant

Job Posting Organization:
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. UNEP was established in 1972 and has since grown to encompass a wide range of environmental issues, operating in over 100 countries with a diverse workforce of approximately 1,000 employees. UNEP's mission is to encourage sustainable development through sound environmental practices, and it plays a crucial role in coordinating responses to environmental challenges on a global scale.

Job Overview:
The Climate Mitigation Modelling Consultant will provide essential technical modelling support to the PAF and NDC Act & Invest projects implemented by UNEP, focusing particularly on the Long-Term Low-Emission Development Strategy (LT-LEDS) processes and sectoral mitigation modelling in key areas such as energy and transport. The consultant is expected to deliver a comprehensive modelling workplan that includes an inventory of models, data sources, key assumptions, scenario definitions, and a quality-assurance approach. The role involves reviewing baseline and mitigation scenarios for key partner countries, producing sectoral mitigation modelling outputs, and developing technical notes and training materials to support national counterparts and project teams. The consultant will also be responsible for ensuring methodological consistency across country processes and assisting UNEP in responding to additional modelling requests from partner countries.

Duties and Responsibilities:
The consultant will be tasked with providing technical modelling support to the PAF and NDC Act & Invest projects, which includes developing reference and mitigation scenarios, conducting sectoral mitigation modelling, and ensuring alignment with national GHG inventories and NDC targets. Specific duties include reviewing existing modelling work, compiling and validating data, developing long-term emission projections, quantifying emission reductions, and preparing technical notes and guidance materials. The consultant will also be responsible for reviewing technical aspects of proposals developed with key partner countries, providing structured feedback, and ensuring that all modelling outputs are documented and organized for future use. Additionally, the consultant will liaise with national modelling teams and provide training and technical inputs to enhance the capacity of national counterparts.

Required Qualifications:
Candidates must possess an advanced university degree (Master's degree or equivalent) in fields such as energy systems, environmental or energy engineering, economics, climate science, or environmental sciences. A minimum of 8 years of progressively responsible professional experience in climate change mitigation modelling, energy system modelling, or greenhouse gas emission scenario analysis is required. Candidates should have experience in developing baseline and mitigation scenarios using recognized modelling tools, conducting sectoral mitigation analysis, and linking mitigation scenarios to costing and investment needs assessments. Strong documentation skills for both technical and non-technical audiences, as well as experience in delivering training or technical guidance, are essential. Proficiency in Excel and at least one programming or statistical environment is also required.

Educational Background:
An advanced university degree (Master's degree or equivalent) in a relevant quantitative field such as energy systems, environmental or energy engineering, economics, climate science, or environmental sciences is required for this position. This educational background is crucial for understanding the complexities of climate mitigation modelling and the technical aspects of the projects involved.

Experience:
The position requires a minimum of 8 years of progressively responsible professional experience in areas related to climate change mitigation modelling, energy system modelling, or greenhouse gas emission scenario analysis. Candidates should have a proven track record of developing baseline and mitigation scenarios and long-term emission projections using recognized modelling tools. Experience in sectoral mitigation analysis across various sectors, including energy, transport, and agriculture, is also necessary, along with a strong understanding of linking mitigation scenarios to investment planning.

Languages:
A strong command of English, both spoken and written, is required for this position. Working knowledge of French would be considered an asset, as it may facilitate communication with French-speaking counterparts and enhance collaboration within the UNEP framework.

Additional Notes:
The position is home-based and is expected to last for 8 months, from November 25, 2026, to July 20, 202
