 Why did you think it was important to write this paper? Well, ISO 26000 has really made quite a big impression on the world of standards and in the world of sustainability and corporate responsibility as well. And ISO standards can have a big impact if you think about ISO 14001 it is used by hundreds of thousands of companies worldwide. And of course ISO 26000 is squarely addressing the issues of sustainability and sustainable development. Therefore I thought it was important to try and understand the kind of impact that it was having or could have. And how can you assess the impact of a standard like ISO 26000? Well it's hard, it's hard because it's not a standard like ISO 14001 which is a certifiable standard so there are very clear criteria for whether or not someone is actually using it in a formal sense. That's not the case with ISO 26000 it's a guidance standard but it can still have a lot of influence. It has already influenced the debate about what it is legitimate to consider as part of sustainable development. It has meant a much broader range of issues and substantive issues like human rights as well as the environment and many others are all now considered to be part of sustainable development. It has also influenced a number of very significant institutions for example the European community whose new definition of CSR corporate social responsibility has been revised and a new one is awfully like ISO 26000's definition of social responsibility. And even ISO itself is now rethinking the way it approaches all its standards and there are a great many of them to consider whether or not sustainability issues are properly integrated within them. And then of course it can make a difference through how companies actually use it which is perhaps the key. What are the main pathways for its influence? Well one as I said is through organisations through the actual use which organisations of all sorts make of it because it is not just applicable to companies it's also applicable to every kind of organisation. And as I said it has reset the agenda which is very important. Well companies are certainly looking at it and one I think of the most common ways of using it is to review their existing practice against what's suggested in the guidance standard and to look for gaps hopefully. There's also quite a lot of use which is unacknowledged so you can clearly see its influence in some sustainability reports because of the way they're structured. But what is very hard is to know how much difference and how much good practice there is as a direct result of the standard. On the other hand you need to remember that it's actually although the standard came out over a year ago it's actually relatively early days and I can only think that its influence will grow over time. And do you think it will make a real positive difference to sustainability development? Well I hope so. I hope so. So it is squarely aimed at that, at those issues. It is being taken very seriously and even if it does no more than to legitimise the full scope of issues relevant to sustainable development it will have made a significant difference.
