Progressively achieve carbon neutrality

Increase use of renewable energy to 15% of total energy use by 2010 (10.5% in 2006)
Reduce net PFC emissions to 10% versus 1995 by 2008 (net reduction in 2006 versus 2005: 2.6%)

The table is slightly different than the one presented in 2005 (transportation emissions are integrated in the total emissions) (*) The transportation emissions value is a global estimate of employees’ transportation and transport of goods. (**) We found a discrepancy in our table last year; we have modified it this year to disclose the relevant data.

 

Alternative and renewable energy | EN18 | STEV37 | 3.3 |	%
In 2006 the percentage of CO2-free energy used in ST was 17%, compared to 2% in 2005. This includes hydroelectricity, nuclear energy, wind energy and photovoltaic. The increase versus 2005 is mainly due to a change of energy provider in Italy.
Note: The parameter of this indicator has changed in 2006 and now includes nuclear energy.

Summary of greenhouse gas emissions

ST considers global warming as one of the most critical issues to be treated and works on it by decreasing the level of greenhouse gases (GHGs) released into the atmosphere during manufacturing activities.

The table above gives a summary of our greenhouse gas emissions.
In 2006:

• ST had an 11% decrease of CO2 emissions related to energy
• The green energy provided by our suppliers was particularly high in comparison to 2005
• For the first time in our history, ST also decreased net direct PFCs. This was possible thanks to considerable investments on abatement systems implemented in Singapore during the year, and to the fact that we reached 80% of our worldwide CVD tools equipped with point-of-use abatement systems.

The sequestration of CO2 due to the implementation of reforestation projects is increasing over the years, thanks to the growth of trees planted in Australia (2,600 ha), Morocco (4,800 ha), Texas (1,400 ha) and in other regions (100 ha).

All of the above actions contribute to a decrease of more than 8% in the total net CO2 emissions.

Energy produced by ST wind farm

ST’s wind farm located in the South of France has produced 29% less electricity in 2006 than in 2005, due to technical problems that occurred in a turbine.

Environmental incidents | EN23 |

In 2006, we identified a problem of soil contamination in our manufacturing site in Tours (France); the site management has immediately reacted by preparing a remediation plan in coordination with the competent authority. The problem is under control and has not generated any fines or penalties.

Our site in Rennes (France) has identified a potential groundwater organic contamination. A detailed investigation is ongoing, and measures will be taken to remediate the problem in collaboration with local authorities. This potential problem has not generated any fines or penalties.
