			<content:encoded><![CDATA[<p><span style="color: #808080">A <span style="color: #000000"><strong>carbon footprint</strong></span> is a measure of the impact our  activities have on the environment, and in particular climate change. It  relates to the amount of greenhouse gases produced in our day-to-day  lives through burning fossil fuels for electricity, heating and  transportation etc.</span></p>
<p><span style="color: #808080">The carbon footprint is a measurement of all  greenhouse gases we individually produce and has units of tonnes (or  kg) of carbon dioxide equivalent.</span></p>
<p><span style="color: #808080">A carbon footprint is made up of the sum  of<span style="color: #000000"> two</span> parts :</span></p>
<p><span style="color: #808080">(A) <strong><span style="color: #000000">The primary footprint</span></strong> &#8211; Home( gas, oil and coal )15% ,Home( electricity)12%, Private transport 10%, Public transport 3%, Holiday flights 6%</span></p>
<p><span style="color: #808080">(B) <span style="color: #000000"><strong>The secondary footprint</strong> </span>- Share of public services 12%, Financial services 3%, Recreation and leisure 14%, House( Building and fumishings) 9%, Car manufacture and            delivery 7%, Clothes  and personal effects 4%, Food and drinks 5%</span></p>
<p><span style="color: #808080">1. The <span style="color: #000000"><strong>primary footprint</strong></span> is a measure of our direct emissions of CO2  from the burning of fossil fuels including domestic energy consumption  and transportation (e.g. car and plane). We have direct control of  these.</span></p>
<p><span style="color: #808080">2. The<span style="color: #000000"> <strong>secondary footprint</strong></span> is a measure of the indirect CO2  emissions from the whole lifecycle of products we use &#8211; those  associated with their manufacture and eventual breakdown. To put it very  simply – the more we buy the more emissions will be caused on our  behalf.</span></p>
<p><strong><span style="color: #000000"><span style="text-decoration: underline">WAYS TO REDUCE CARBON FOOTPRINT</span></span></strong></p>
<p><span style="color: #808080">For Individuals</span></p>
<p><span style="color: #808080">Here&#8217;s a list of simple things you can do immediately</span></p>
<p><span style="color: #808080">1)Turn it off when not in use (lights, television, DVD player, Hi Fi, computer etc)</span></p>
<p><span style="color: #808080">2)Turn down the central heating slightly (try just 1 to 2 degrees C). Just  1 degree will help reduce your heating bill by about 8%.</span></p>
<p><span style="color: #808080">3)Turn down the water heating setting (just 2 degrees will make a significant saving)</span></p>
<p><span style="color: #808080">4)Check the central heating timer setting &#8211; remember there is no point heating the house after you have left for work</span></p>
<p><span style="color: #808080">5)Fill your dish washer and washing machine with a full load &#8211; this will save you water, electricity, and washing powder</span></p>
<p><span style="color: #808080">6)Fill the kettle with only as much water as you need</span></p>
<p><span style="color: #808080">7)Do your weekly shopping in a single trip</span></p>
<p><span style="color: #808080">8)Hang out the washing to dry rather than tumble drying it</span></p>
<p><span style="color: #000000"><strong>The following is a list of items that may take an initial investment,  but should pay for themselves over the course of 1-4 years through  savings on your energy bills.</strong></span></p>
