Students at Queen's are claiming victory after the university committed to ending its investments in fossil fuels companies.
A high-profile campaign by Fossil Free QUB saw campaigners stage a five day sit-in in 2015, occupying an admin building.
Activists said the commitment would see the university phase out investments in companies involved in extraction and production of fossil fuels by 2025.
Campaigner Sean Fearon said: "Queen's University has made a bold statement about its commitment to combating climate change."
A staff member added: "We're thrilled that Queen's University Belfast has made history in becoming the very first university in Northern Ireland to divest from fossil fuels."
Recent figures suggest the university has over £5million invested in the industry, including over £1m in Shell and BP.
