The university has been ranked third out of all UK universities in the People and Planet 2016 table published in The Guardian.
This means that Manchester Met has maintained a top three position since 2013, testament to its continued drive to embed sustainability across the university.
The People and Planet University League is the only comprehensive and independent league table of UK universities that ranks institutions by environmental and ethical performance.
Vice-chancellor Prof Malcolm Press said: “We are delighted to have once again maintained our position in the top tier of UK universities for commitment to sustainability and the green agenda.”
In 2007, success in environmental sustainability and ethical performance was low at Manchester Metropolitan.
The university was 91st in the People and Planet University League, formerly known as the Green League. By 2013, it was ranked 1st.
Malcolm added: “Our position shows that the university continues to grow its delivery and breadth to be a top performer in this field.
“We also encourage our students to think globally and to tackle the major environmental issues that the world currently faces across the breadth of our courses.”
