Variations of the Earth’s surface temperature for the past 1,000 years

June 2, 2009 3

Main climate impacts

• Sea levels rise

• Higher temperatures - especially

on land

• Hydrological cycle more intense

• Changes at regional level

Not All GHGs are Equal

Carbon Footprint – 3 Scopes

June 2, 2009 7

Remember: there are three levels (scopes) to a green house gas/carbon footprint calculation.

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, 2009 8

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, 2009 9

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

Carbon Footprint – 3 Scopes

June 2, 2009 11

Carbon footprint calculations must include at least Scope 1 and 2 GHG emissions.

• 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

Conclusions

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 CO2/km, this week a Volvo S40 was ordered.

• Travel by public transport or cycle is promoted since 2000.

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.
