About the Role

The Impact division supports all One Acre Fund programs to generate more impact, wherever we work. We help the organization keep three core aspects of impact at the forefront of our work:

Improve farmer livelihoods and profitability in the short term
Ensure long-term viability through sustainable agricultural practices (soil health, crop diversity, etc.)
Address non-agricultural needs of farming households (energy, nutrition, etc.)

The Sustainability Lead role has two core responsibilities. First, the Lead oversees the measurement and analysis of One Acre Fund’s environmental impact, including emissions accounting and environmental and social impact assessments. Second, the Lead drives improvements in sustainability through targeted initiatives and cross-functional projects that address identified gaps. This role requires close collaboration with colleagues across our ten countries of operation and multiple functional areas, such as supply chain, logistics, and field operations, as well as coordination with external partners. We are therefore seeking a highly organized project leader who is also a strong cross-team collaborator.

The Sustainability Lead sits within One Acre Fund’s Impact Division and reports to the Senior Impact Director. The Impact Division includes several core functions, such as the central Agricultural Research & Consulting team and the Monitoring, Evaluation, & Learning team. It also leads key organization-wide initiatives, including agricultural insurance, payments for ecosystem services, behavioral research, nutrition and health, emissions accounting, and environmental impact assessments.

Responsibilities

Lead Annual Emissions Calculations

Work with all relevant departments to gather data/inputs for footprint accounting.
Clean and share data with partners for independent review and calculation.
Build internal long-term tracking tools to help us understand our emissions hot spots and mitigation opportunities.
Help set and track progress against global and program-specific emissions reduction targets.

Lead key strategic projects to reduce emissions in hot-spot areas.

Prioritize a few key mitigation opportunities to tackle at a time based on size and feasibility of potential reduction.
Work with teams across the organization (program teams, inputs/sourcing teams, operations teams, etc.) to reduce emissions in their operations or purview. This will require research & learning about the specific emissions hotspot and potential solutions, evaluating options with program teams, and implementing agreed-upon actions.

Manage our Environmental & Social Impact Assessment (ESIA) process for all products and services offered by 1AF.

Ensure that programs adhere to ESIA processes, including evaluating potential new products and services and implementing any mitigating actions required.

If approved, and if there is not already a clear owner, lead these innovations and improvements.
