Explanation of diagram
How to understand the key
We have illustrated the condition of different topics using a
diagram, placing each environmental topic on a spectrum from red to
green which represents our current (2011) understanding of its
state. The arrow represents the direction and extent of the
potential change expected over the next 15 years.
We have defined both the position on the spectrum and the trend
using judgement, based on available information. For some topics
there is a good body of evidence to support the assessments, other
topics rely more on expert judgement.
We aim to progressively improve the robustness of this process
over the next year, including holding a wider consultation on the outputs.
The example above illustrates a part of the environment that is
currently amber, but in 15 years’ time will have improved to
The example above illustrates a part of the environment which is
currently amber and we do not believe there is a trend.
