The Draft Core Strategy for Babergh is considered by the Council’s Strategy Committee.

The document is 116 pages plus appendices. Regrettably there is no comprehensive table of contents (page numbers are omitted) nor is there an index. The obvious question is whether this is deliberate. A document which has taken years to put together is debated for less than a day. How many councilors in the towns and parishes will read through the document?
However Page 6 Key Environmental Issues includes:
CO2 levels of emissions in the Babergh District are above regional and national averages and this part of East Anglia is particularly vulnerable to the effects of climate change. It is therefore important that we look at ways to contribute to reducing climate change in the district including more sustainable energy generation and energy use / conservation.
Traffic congestion, and air pollution due to traffic are also important issues in some parts of the district. The potential pollution hotspots relate to the A12 and A14 trunk roads and the A131 southern approach to Sudbury, which carry relatively high volumes of fast-flowing traffic. The Ballingdon Street, Cross Street and Church Street area of Sudbury has been designated an Air Quality Management Area (AQMA) as a consequence of traffic  congestion and air pollution.
The above average pollution level assertions apparently come from a 2008 publication from Suffolk County Council. Page 55 of the Development Framework gives an indication of some of the measures to be taken to reduce greenhouse gases but nothing is specific. I suspect that the figures and the conclusion are out of context or otherwise flawed. It’s possible that the A12/A14 Copdock interchange has been monitored but this junction is not representative of the District. (see http://www.streetmap.co.uk/newmap.srf?x=611500&y=241500&z=3&sv=611500,241500&st=4&ar=Y&mapp=newmap.srf&searchp=newsearch.srf&ax=611500&ay=241500)

The hunt for truth (and its consequences) continues.
