I've just come across a new and intriguing word...intrapreneurship! I'd never heard of this word before a Sustainable Brands Article. The wikipedia definition is "the act of behaving like an entrepreneur, except within a large organization rather than a market as a whole."
Interesting concept. I think it embodies the most admirable trait of the executives I most admire. An innovative spirit for risky projects. These projects usually contribute to a highly genuine CSR campaign - the most successful type.
Here's a great example of one I read today...a Grist post - A Wisconsin hospital is powered by beer and cheese. - what a great story!
I hope I can be like this one day when I'm a Corporate Sustainability Officer :)
