3. Environmental deterioration demonstrates internationally agreed goals have only been partially achieved

Many sub-national, national and international instruments now in place are contributing to environmental improvements. There is evidence, however, of continuing deterioration in many places and for most of the global environmental issues reported on in GEO-5. For such issues as exposure pathways and effects of chemicals, and the trends in land degradation a better understanding would support better responses. For others, such as reducing particulate matter (PM) concentrations in the atmosphere, more consistent implementation of existing instruments is needed.
