They say:

The 50 companies on our 2011 list have chosen a unique path. Today's business landscape is littered with heritage companies whose CEOs battle their industry's broken model with inertia, layoffs, lawsuits — anything that squeezes pennies and delays the inevitable. How many of these companies will be dominant in 2025? Few.

That world will be ruled by the kinds of companies on this list. They're nondogmatic, willing to scrap conventional ideas. (A mere 30-second TV ad? Let's do 200 online videos in two days, say the creatives at Wieden+Kennedy.)

It's a real honour to be included to be on this list, which mentions no other ad agencies and includes the likes of Apple, Google, Nike, ESPN and Amazon.

W+K planner Sophie Dollar today presented our project Off-On at the M&S Sustainability Conference at the Queen Elizabeth Conference Centre in Westminster.

Off-On's key objective is to encourage employees to do more good by behaving in a more environmentally responsible way.

Today's annual conference is part of M&S's commitment to corporate social responsibility and is part of 'Plan A' – an initiative the company launched in 2007 which has set out 180 commitments to achieve by 2015.  M&S's ultimate goal is to become the world's most sustainable, major retailer.

Sophie presented Off-On as part of the afternoon session: 'How to engage your employees' – and continued to spread the word that a democratic, simple and accessible idea is the key to sustainable behaviour change.

Judging by the string of delegates queuing to congratulate her following her slot – people are certainly listening!
