CAT opened the Wales Institute for Sustainable Education in Jume 2010
Staff at the Centre for Alternative Technology (CAT), near Machynlleth, have voted to take a pay cut of almost 10% to safeguard the company's future.
All 162 staff members agreed to take the 9.9% reduction in wages for four months from December 2010 until March 2011.
Management, trustees and the board of directors have started a review to try and consolidate the centre's position.
The centre employs 97 full-time and 65 part-time or seasonal employees.
CAT is an eco-centre based at Pantperthog, dedicated to demonstrating and teaching sustainable development.
Its external relations director, Paul Allen, said: "Like other charities we are facing losses in income because of the recession.
"We saw a slight drop in visitor numbers to 50,000 last year but our problems are driven by the global situation.
"The staff voted to take a voluntary temporary pay cut of 9.9 per cent across the board, which is a testament of their support for the centre's vision."
More than 50,000 visited the centre last year
Mr Allen added that the management team, trustees and board of directors were looking at ways to consolidate CAT's position in the future.
The centre is open to visitors, holds residential courses and publishes information on organic farming, gardening and ecologically-friendly living.
Chairman of CAT's trustees, Dr Iolo ap Gwynn, said the staff's voluntary pay cut had given CAT a measure of stability.
When asked if the review would result in job losses and reduce services, Dr ap Gwynn said: "We can't say anything at the moment, but this is a good opportunity to look at how CAT is run.
"The review will probably be ongoing until March 2011."
In June 2010, CAT opened its state-of-the-art Wales Institute for Sustainable Education (WISE) building to teach environmental courses.
The £8m project has enabled students to study courses on wind power, solar water heating and organic gardening.
It includes a 200-seat circular lecture theatre named after one of CAT's benefactors, Graham Sheppard, who donated £650,000 towards the WISE project.
