BT has been recognised as one of the top companies in the UK in the Observer's recently-published 2008 Good Companies Guide.
The telecoms giant has plans in place to invest £1.5 billion in a UK-wide fibre-optic broadband project set to reach ten million British homes by the year 2012.
Now the provider has been named as one of the top three in the newspaper's list, climbing three places to number three.
BT Group director of corporate responsibility Caroline Sheridan said that she was happy with the news, commenting: "This is a tremendous achievement for everyone in BT. Responsibility and sustainability are at the very heart of BT and I'm delighted that our achievements and continued commitment have been recognised."
The Observer praised BT for its corporate responsibility, while acknowledging that it is powerless to avoid the knock-on effects of the current economic downturn.
BT recently announced it would be cutting 10,000 jobs by the end of 2009 in a bid to reduce costs.
