1. CARBON FOOTPRINT AQUATREAT By Jan Vandersypen Distributors meeting 29.01.2010

2. Variations of the Earth’s surface temperature for the past 140 years June 2, 20092

3. Variations of the Earth’s surface temperature for the past 1,000 years June 2, 20093

4. Main climate impacts Sea levels rise Higher temperatures - especially on land Hydrological cycle more intense Changes at regional level June 2, 20094

5. 5

6. Not All GHGs are Equal Greenhouse Gas Global Warming Potential Carbon Dioxide, CO 2 1.0 Methane, CH 4 21 Nitrous oxide, N 2 O310 HFC 134a1,300 Sulfur hexafluoride23,900 All GHGs Converted to a CO 2 Equivalent June 2, 2009

7. Carbon Footprint – 3 Scopes Carbon Footprint Scope 1: Direct Emissions Scope 2: Indirect Emissions (Purchased energy) Scope 3: Other Indirect Emissions June 2, 20097 Remember: there are three levels (scopes) to a green house gas/carbon footprint calculation.

8. Scope 1: Direct Emissions Relatively easy: –Combustion Sources –Site owned vehicles –On site electrical generation –CFC and HFC losses from refrigeration equipment –Sulfur hexafluoride losses from electrical equipment June 2, 20098

9. Scope 2: Indirect Emissions – Purchased Energy Emissions from consumption of purchased utilities: –Typically electricity –Could be steam or high temperature hot water –Could be negative (ex: electricity from landfill gas) June 2, 20099

10. Scope 3: Other Indirect Emissions Can be very difficult: –Transportation of purchased material or goods –Employee business travel –Employee commuting impacts –Outsourced work –Emissions from finished products –Transportation of waste –Vegetation & Trees Scope 3 has various challenges –Boundary issues –Can be a magnitude higher than Scope 1 and 2 –Costly value chain analysis June 2, 200910

11. Carbon Footprint – 3 Scopes Carbon Footprint Scope 1: Direct Emissions Scope 2: Indirect Emissions (Purchased energy) Scope 3: Other Indirect Emissions June 2, 200911 Carbon footprint calculations must include at least Scope 1 and 2 GHG emissions.

12. Get familiar with your facilities “carbon footprint” Think carbon footprint reduction as a matter of good business Think about where the source data lies for a phase 1&2 calculation Help to forward lean – we need to be a leader not a follower June 2, 200912 Conclusions

13. AQUATREAT ACTIONS CF REDUCTION ACCOMPLISHED Solar panels produce half of our electricity needs, installed 02.2008 Sun evaporator reduces our waste water by 30% installed 1999. Rain water is captured, filtered over sand filter, reversed osmosis and mixed bed, reduces our drinkwater consumption with 50%, started 1999, storage capacity 35m³, adapted in 2004, storage capacity 60 m³. Relighting of our warehouse reduces total electricity consumption with 20% since 2008. All new company cars will produce less than 105 gr CO 2 /km, this week a Volvo S40 was ordered. Travel by public transport or cycle is promoted since 2000.

14. AQUATREAT FUTURE ACTIONS ON CF REDUCTION New production facilities will reduce our water and energy consumption to 0! By producing sufficient renewable electricity to cover all our internal energy needs.....fuel cells or hydrogen will store excess electricity. CF of raw materials and packaging will be taken in account in our purchase conditions. New technologies are studied to generate energy from our waste and to build a small cogeneration unit with a microturbine. Transport from and to our facilities will be optimised to achieve lowest possible CF.
