As organisational director at Greenpeace UK, Matthew Pollitt has the job of making us put our money where our mouth is by improving our environmental performance, and reporting on progress to our supporters.
As a campaigning organisation we measure success in terms of shifts in policy or public perception. Internal efficiency and effectiveness - my responsibilities as organisational director - are quite rightly seen as a means to an end rather than an end in themselves.
Similarly, people don't generally visit the Greenpeace website to learn about what I do. One exception is the interest we get in what we are doing to minimise our own impact on the environment.
