| Energy Cunsumption |
 |
|
Data for 2005 and higher include SEED light sites. The trend over the last years shows that Sulzer has improved its eco-efficiency: energy consumption per net value added decreased according to the set target for the last five years by 45%, energy consumption per employee decreased by about 10%.

| Energy Sources Mix |
|
Data for 2005 and higher include SEED light sites. In 2007, electricity, natural gas, and district heating comprised over 95% of the total energy demand; electricity only over 65%. Other shares are negligible. Compared to 2006, the share of electricity increased by six percentage points, whereas gas decreased by about two percentage points, all other shares decreased just slightly. The changes in 2007 are mainly due to the integration of SEED light sites.

| Consumption by Sources |
|
| Greenhous Gases |
|
|
Data for 2005 and higher include SEED light sites. The values are CO2 equivalents calculated from direct emissions due to the use of fossil energy sources, natural gas being the main source. Emissions from other production processes are not relevant. Indirect emissions are not included. In 2007, both the absolute and specific emissions decreased due to a changed energy mix.

| Photosmog |
|
|
Data for 2005 and higher include SEED light sites. These emissions originate from the use of chemicals, mainly for surface treatment processes, e.g., degreasing. Therefore, the emissions are directly linked to the production mix. Except for 2004, the increase in emissions has not been proportional to the increase in production.

| Ozone Depleting |
|
|
These emissions originate from the use of chemicals, e.g., degreasing processes, which relates to the production mix of Sulzer. Due to the pilot operation of surface treatment processes at one site, the emissions increased significantly in 2004. The emissions have been reduced since 2005 due to more environment-friendly processes.

| Acidification Potential |
|
|
Data for 2005 and higher include SEED light sites. These emissions originate from the use of fossil energy sources—basically fuels and fuel oils—as well as from the use of chemicals. The absolute and specific emissions mainly reflect changes in the consumption of energy sources.

| Water Consumption |
|
|
Data for 2005 and higher include SEED light sites. The increase in water consumption in 2005 originates mainly from a leakage at a single site. In 2007, the consumption per net value added decreased by about 15%, while the consumption per employee was stable. In 2007, approximately 75% of the overall water consumed was used for cooling and 15% for sanitary and drinking purposes.

| Waste |
|
|
The quantities per net value added decreased steadily according to the targets set over the last five years, with the exception of 2006, on the ground of continuous growth in production. The type of waste, especially municipal solid waste and external recycling, varies from year to year. It depends on the product mix as well as on the specific activities at the sites.

| Land Use |
|
|
Data for 2005 and higher include SEED light sites. Together, the companies occupied about 1 860 000 m2 of land. Thereof, approximately 40% is impermeable land. In 2007, a single site occupied on average about 31 000 m2. This figure has decreased in 2007 by about 5% due to sold premises and opening of smaller sites.

| Relevance of Selected Costs |
|
|
Data for 2005 and higher include SEED light sites. The illustration shows the relevance of the external cost of acidification, ozone depletion, photo smog, and the greenhouse effect in comparison within the energy, water, and waste costs that are also collected with Sulzer’s annual sustainability data collection. Moreover, the illustration shows that energy costs—at about CHF 34 million—are the most substantial factor of the selection. Energy costs have increased significantly in the last two years. Waste management has been improved continuously over the last several years, with the effect that a significant quantity of the waste can now be sold (recycling). The costs of water and external costs of emissions to air are low. In 2007, the cost of water amounted to CHF 2.6 million; the calculated external costs of the emissions to air to CHF 450 000. At least 50% of these costs originate from the use of fossil energy sources. The external costs are based on the following cost rates: Greenhouse effect: CHF 10 per t CO2 equivalent; photo smog: CHF 3 000 per t ethylene equivalent; ozone depletion: CHF 20 000 per t FCKW-11 equivalent; acidification: CHF 5 000 per t SO2 equivalent.

| Extrapolation to Sulzer Corporation |
|
| In 2007, approximately 1 200 employees were not covered from the sustainability data collection. The majority of these employees work in support functions such as sales and finance. The data of Sulzer’s core businesses were thus estimated based on average data for non-productive activities (energy: 30 GJ per employee and year, water: 15 m³ per employee and year, waste: 0.3 t per employee and year). The extrapolation results in an increase in energy consumption by 4% (in total, to 826 000 GJ), in water consumption by 1% (in total, to 1 727 000 m³), and waste production by 1% (in total, to 40 500 t). The extrapolation further shows that supporting activities have little impact on the environmental performance of Sulzer. |
