Introduction
• Participation in the ECO Stars scheme is intended to facilitate
improvements in the environmental performance of vehicle fleets in the
South Yorkshire area.
• The Environmental Evaluation uses two ‘case study’ fleets to examine the
trajectory of environmental progress made through participation in the
scheme:
• Clipper Logistics
• Doncaster Council
• This evaluation focuses on the environmental progress seen as a result of
the fleet review and replacement policies and practices in place within
each of these two fleets.
• Note that other measures within the ECO stars programme, such as fuel
management, driving training and anti-idling measures, will also help to
reduce emissions.
Environmental Impacts
Two of the main environmental impacts of road traffic are:
• the impacts of toxic pollutants on local air quality; and
• the contribution of greenhouse gas emissions to climate change.
Air Quality: Air quality is determined by measuring the type and quantity of
different pollutants in the air. The UK National Air Quality Strategy sets limits
for the quantity of a number of pollutants, known as air quality objectives.
Most exceedences of these air quality objectives are due to emissions from
traffic of the pollutants nitrogen dioxide (NO2) and particulates (PM10).
Climate Change: The Climate Change Act 2008 sets targets for UK carbon
emissions, and in working towards achieving these there is likely to be an
increasingly greater policy emphasis on carbon reduction.
Methodology
•Two ‘case study’ fleets were used to examine the trajectory of environmental
progress made through participation in the scheme.
•The fleet profile for four years was examined:
• At registration – the data provided when initially registering with the scheme.
• Start 2010 – the current profile of the fleet registered with the scheme.
• Start 2011 – the predicted profile of the scheme in the first quarter.
• Start 2012 – the predicted profile of the scheme in the first quarter.
•The fleet information was analysed to identify the types and numbers of vehicles
complying with each vehicle emission standard - known as Euro standards, and
consequently the emissions.
Clipper Logistics - fleet
The Clipper fleet is made up of a small number of heavy vehicles
which each travel large distances each year.

Doncaster Council - fleet
The Doncaster fleet is made up of a large number of vehicles, predominantly
light and medium vans, with some HGVs and specialist vehicles, which travel
small distances in the local area.

Conclusions
•
Proactive fleet renewal can have a significant impact on reducing levels of toxic
emissions within a relatively short timescale - both fleets show a significant
reduction in the percentage of toxic emissions – with reductions of up to 75% for
PM10 and 50% for NOx.
•
Focussing on the most heavily polluting vehicles (HGVs) can yield high levels of
emissions benefit - for toxic emissions the percentage and total reductions were
more significant for the Clipper Logistics fleet.
•
Fleet renewal did not show the same benefits for the reduction of CO2 emissions,
with only a small (3-5%) reduction in emissions seen over the four years. This is
because progressive reduction in CO2 emissions was not incorporated into the
Euro emissions standards in the same way as for toxic pollutant emissions. It
should be noted, however, that the ECO Stars scheme also includes other
measures to improve environmental performance by reducing fuel consumption
and, by extension, CO2.
