Abstract

1/ CO2 Emissions Management Program at Merck Millipore Molsheim (France)

Molsheim Site has defined a goal to reduce its carbon footprint of 20% regarding C02 direct emissions linked to primary energy usage. This objective is aligned with Merck Corporation Goal.

Molsheim 2011 CO2 Emissions: 2432 tons

2006 baseline 2719 Tons

2020 Emissions Target 2176 Tons

2/ The various components of the reduction program

- Improve Operation of current Facilities

- Recover energy when applicable

- Take opportunities of equipments replacement to select the most efficient one

- Design new Facilities using most efficient technologies

- Monitor consumptions & define energy efficiency metrics to identify major contributors (you only improve what you measure)

- Use renewable sources of energy

3/ Reduction of CO2 Emissions linked to the management program:

2006-2011: 403 Tons

2012-2013: 134 Tons

2014-2015: 138 Tons

2016-2020: 337 Tons

Total: 1012 Tons

(Abstract continues on next page ...)

In the mean time:

- buildings have & will be constructed ( + 265 Tons of CO2)

- production volumes will increase ( + 78 Tons of CO2)

- project with negativ impact will be implemented ( +79 Tons due to gas versus electricity usage)

4/ Lessons learned

A yearly reduction of 3% can be achieved:

- Implementing actions not requiring hudge Engineering.

- Taking opportunities of equipments replacement with the most efficient available technology

- Sustaining implemented actions.

To achieve 20% reduction including new buildings, site evolutions,etc this requires a major investment to be placed during the program to significantly reduce emissions (Biomass for ex.)

Some purely cost saving actions could have a negativ impact as replacing electricity usage with natural gas usage for the same amount of energy.

Pay backs are significantly different following type of actions.

It’s not to late starting today. Molsheim Site will achieve the goal in 10 years starting 2006.
