The National Magazine Company knows all about the birds and the bees. The organisation that brings us Cosmopolitan and Prima Baby and Pregnancy, as well as Esquire, Good Housekeeping and Country Living, offers London's birdlife a retreat from the city with its Soho roof garden, which is home to compost-producing wormeries, too. Beehives are the next project on the list.

Wildlife isn't the only thing to benefit from NatMag's social conscience. The company sends magazines to hospitals, books to Oxfam and mobile phones for recycling. The 860-strong workforce says the organisation is well run, giving it an 80% positive green score. The firm's environmental management system is certified to ISO 14001 standard, and staff receive regular communication on environmental issues (77%). They are offered a pension scheme with an ethical investment policy (a top 10 score of 65%).

There is a generous budget for green initiatives, with NatMag investing £108,000 for such purposes last year. The offices are in the process of having solar shading fitted to their double glazed windows, which it is estimated will cut energy bills by up to 20%. Staff don't think environmental initiatives are a waste of money (91%) and say being ecofriendly is an everyday consideration at NatMag (80%). They know where to put waste for recycling (95%), and bosses encourage this (75%).

NatMag aims to eliminate its carbon footprint of 4,000 tons by 2013 by becoming carbon neutral, and offset any residual via the Carbon Neutral operation through development projects in Asia.

Staff say their employer meets environmental targets year on year (68%), and efforts to keep reducing the firm's environmental impact are ongoing. Air conditioning is switched off during the summer, the heating is turned down by one degree during winter months, and movement sensors mean lights aren't on unnecessarily.

Cavity wall insulation keeps employees warm, all new toilets are dual flush, which use less water, and the remainder have Hippos fitted — devices that save three litres of water per flush. People at NatMag don't associate being green with beards and sandals (85%). A top 20 score of 79% shows that bosses don't expect staff to save the environment while they themselves drive cars with poor rates of fuel economy.

There are staff prizes of up to £200 in a monthly contest for the best idea to increase efficiency and save money, and being green certainly doesn't stop people from getting on with their job (82%).
