GreenSheep
SRUC's low carbon sheep research that's paving the way for more sustainable, circular farming.
Low carbon sheep for sustainable, circular farming.
SRUC's GreenSheep facilities and research supports local and international aims to lower the environmental impact of greenhouse gas emissions from small ruminants (sheep and goats) by improving knowledge and development of:
- the genetic control of carbon dioxide and methane emissions;
- the effects of breed, diet and parasite burden on emissions; andÂ
- proxy measures for methane emissions and interactions between rumen volume, rumen microbiome, and methane emissions.
GreenSheep Facilities
GreenSheep research is focused around twelve portable accumulation chambers (PACs) housed on a trailer that can be taken to sheep and goats to measure methane emissions after eating their usual diet, including grazing. The accumulation chambers allow researchers to quickly and accurately measure the amount of carbon dioxide (CO2) and methane (CH4) that are emitted from an individual sheep over a defined period of time.
GreenSheep facilities also include a mobile CT scanner and portable feed intake recording equipment for sheep. These complimentary technologies collect additional data to relate to PAC-measured methane emissions and helps build a fuller mechanisms involved in reducing methane emissions from sheep.Â

GreenSheep Research
Two of the main GreenSheep projects underway are:
- Breed For CH4nge: Breeding low methane sheep (2023-2026) is measuring 13,500 maternal-type sheep in 30 flocks across the UK for CO2 and CH4 to build and develop the tools required to genetically reduce methane emissions and improve the efficiency of the national flock. The project will demonstrate the impact of low carbon sheep on whole farm carbon footprints. (InnovateUK-funded led by Innovis; UK only)
- Sustain Sheep: Reducing sheep methane emissions – sustainability in practice via new breeding goals (2024- 2027) is building on the foundations of the Grass to Gas project to create the knowledge and infrastructure for the incorporation of genetic merit for low environmental impact into national breeding schemes for sheep and to provide a mechanism for global and national comparison. (International with 6 partners)

SRUC joins new centre tackling food security and climate change
Scientists from SRUC will carry out research into plant breeding and animal nutrition to increase productivity and reduce greenhouse gas emissions as part of a new centre announced by UK Prime Minister Rishi Sunak.
Turning the Climate Tide: The Integral Role of Sustainable Livestock Practices
Given its significant contributions to greenhouse gas emissions, particularly methane, livestock farming finds itself in a critical role. Understanding these emissions’ biogenic nature and shorter atmospheric lifespan not only presents a challenge, but also outlines a pathway for effective mitigation efforts.
