7. Sustainability - Questions & Responses AAPA 2011 Study Tour Group ReportCARBON FOOTPRINTSouth Africa has a carbon tax on emissions implemented on new motor vehicles level of CO 2. Atthis stage a carbon tax does not apply to the road construction or road product sector. There is ageneral awareness of the impact carbon tax / pricing will have on the selection and use ofbituminous and other products. Much of the drive to use emulsions, warm mix asphalttechnologies, increased percentages of recycled asphalt and bituminous stabilized materials(BSM) has been to meet environmental objectives which today match the goal of CO 2 reduction.In discussions it was clear that there was an awareness of the embedded energy aspects, energyper tonne of competing products and the CO 2 outputs for products and construction processes.Sabita has commissioned a study to measure and identify mitigation measures to help membersreduce their energy consumption in the manufacture of asphalt in anticipation of theGovernments plan to introduce a carbon tax. The carbon reduction measures and pay backperiods were reported in a CAPSA paper by Oliver Stotko entitled ‘Energy and related carbonemissions reduction technologies for HMA plants’ and Implication of the Proposed Carbon TaxLegislation and Policy Framework on SABITA members.Question (#4, 6, 7, 8, 14)Q 4. What sustainability and CO 2 reduction drivers exist in the roads sector?Client driven expectations of reduced environmental impact and societal expectations ofsustainable industries are the major influences.Sabita has reviewed the cost and CO 2 generation implications for the production of hot-mixasphalt which for an asphalt plant producing 100 tonnes / day (180 000 tonnes p.a.) would be inthe worst case scenario be in the order of A$0.83 per tonne.As in Australia, the cost shifting that will occur as a result of a carbon tax is being considered in theestablishment of new plant and equipment.

7. Sustainability - Questions & Responses AAPA 2011 Study Tour Group Report“Reducing Greenhouse Gas Emissions: The Carbon Tax Option” consider Long Term MitigationScenarios include carbon taxation and emissions trading.It is not expected that South Africa will lead with significant application on carbon pricing untilrequired by its major trading partners. Sabita has modeled the introduction of the carbon tax,scaling from about A$9 to A$24 per tonne and including the relative cost and benefits of carbonreduction measures in the manufacture of hot mix asphalt.Short term taxation options will likely impose costs on the more affluent parts of the economy notservicing or being funded directly by the state. Direct levies on fuels are considered most likelyfollowed by tax or levies on electricity production.Q 6. Are carbon foot print and CO 2equi calculators being used? If yes, which ones?No formalized road authority endorsed position was presented. There is an awareness of themetric but its application has not been fixed.Sabita is also undertaking through TRL the calibration of the Asphalt Pavement Embodied CarbonTool (asPECT) with software expected to be available to its members by early 2012.Q 7. Are there C0 2equi reduction initiatives in the purchase of bituminous surfacings or asphaltpavements?None were mentioned by the roads agencies consulted, although the general awareness in thelikely future carbon pricing is resulting in project evaluations including the carbon footprint whenevaluating alternatives.Example including the evaluation of energy costs with life cycle costing for 4 pavement typesPapers at CAPSA’11 covered the topic: “Combining LCC and energy consumption for enhanceddecision making regarding rehabilitation options – Kim Jenkins” included the energy involved inthe provision and maintenance of four alternate pavement types over a 20 year life and 30m ESA.The use of discounted live cycle costs and actual energy costs presented an alternate view of theV4-2 Page 103
