With both the public and younger staff members questioning companies about their environmental stance, green PR is a major growth area within the communications field.

Consultants say green PR isn't just about dishing out feel good stories; they warn that companies must tackle harder issues like water use, agriculture and air traffic emissions.

Businesses are also advised to be transparent. If they are not making progress in a particular area they should tell consumers why not and what they are doing about it.
