(*) Includes direct greenhouse gas emissions from our manufacturing plants and indirect emissions from energy consumption and transport, reported in Metric Tons of Carbon Equivalence (MTCE)
(**) Starting in 2006, we have integrated in our indicator the emissions linked to ammonia and we have recalculated the 2004 & 2006 accordingly.
(***) Emissions of substances are considered with threshold limit values below 3ppm, expressed in phosphine equivalent.

Environmental awards 2006 | STEV19 |
In 2006, our company, individual sites and staff have won some environmental awards:
Pengcheng waste reduction: 150 companies took part in this competition based on waste reduction activities 40 companies, including ST Shenzhen site, China, won an award
Environmental distinction awards: the site of Carrollton, USA, won this award for considerable progress, strong environmental leadership and working partnership with the city and other organizations in supporting community sustainability.

Disclosure on management approach

We have a corporate Environment Health & Safety Steering Committee and each manufacturing site has an EHS Steering Committee responsible for implementing the Corporate EHS Policy. Performance indicators for Environment cover 100% of manufacturing sites.

Air and water emissions

Since 2001 ST reports net emissions through the Environmental burden methodology. These net figures represent the air and water emissions of all ST sites in absolute terms, independently from the growth in production capacity. The last 3 years are reported in the above table.

In 2006 most of our eco-indicators improved. In particular the global warming impact decreased by more than 10% due to significant progress in the reduction of PFC emissions in 2006 (7 US$m was invested in the installation of additional abatement systems) and in energy saving (for more details see our environmental performance: « Progressively achieve carbon neutrality »). Thanks to the installation of new abatement systems in Tours (France) and Agrate (Italy), VOC emissions decreased by 6.8%. Air emission toxicity has been reduced by 50% due to additional point-of-use treatment systems.

Up to the year 2005, we integrated, in the eutrophication data we reported on, the downstream water treatment carried out outside ST by local utilities and municipalities. We felt this could lead to errors in our estimation of our water wastage.

For this reason, we have decided from 2006 onwards, to publish the environmental data measured ‘at our gate’, without taking into consideration the downstream treatments. Obviously, our real environmental impact is much lower since our water effluents are processed by waste water treatment plants outside ST. But we feel it is the most appropriate way to measure our impact on local communities, even though we are contributing financially (through the payment of taxes) to the overall waste water processing.

The ozone depletion impact is almost negligible and relates to one ODS substance used in one location. The aquatic eco-toxicity indicator has slightly increased during the last 3 years but ST is operating at 61% of our 2001 performance.

Environmental certifications

All our manufacturing sites are operating under certified Environmental Management Systems (ISO 14001 and EMAS). Our overall management system for environment is mature and robust and all of our sites have been fully certified for at least 10 years.

Compliance with environmental laws and regulations | EN28 |

In 2006, for all our locations / sites at worldwide level we had no fines or penalties
