Disclosures 305-1 Direct (Scope 1) GHG emissions, 305-2 Energy indirect (Scope 2) GHG emissions, 305-4 GHG emissions intensity

The direct greenhouse gas emissions resulting to a large extent from carbon dioxide emissions (CO₂) of the combustion processes operated by Clariant are directly proportional to the amount of carbon in the fuels used. To be able to make a comparable global statement, Clariant uses mean emission factors. Emissions of other greenhouse gases like methane and nitrous oxide (N₂O) are also measured locally and integrated into the consolidated calculation of greenhouse gas emissions.

Indirect greenhouse gas emissions are predominantly generated by external energy procurement, usually in the form of electricity and steam – and thereby almost exclusively CO₂. Their emergence correlates very much with the amount produced and can be less influenced by Clariant than direct emissions. To calculate the emission amounts, country-specific or, in some cases, site-specific conversion factors are used, which are determined on the basis of the existing infrastructure in the country in question. The amount of all greenhouse gases (expressed in CO₂ equivalents) from indirect emissions decreased from 0.54 million t to 0.53 million t, or from 141 to 116 kg per manufactured ton of products, between 2014 and 2017 because of improved energy efficiency and the sale of energy-intensive businesses.

Disclosure 305-3 Other indirect (Scope 3) GHG emissions

As part of its reporting for the Carbon Disclosure Project (CDP), Clariant has calculated Scope 3 emissions for purchased goods, waste generated in operations, employee commuting (all based on WBCSD “Guidance for Accounting & Reporting Corporate GHG Emissions in the Chemical Sector Value Chain”), fuel- and energy-related activities (not included in Scope 1 or 2), upstream transportation and distribution, business travel, and downstream transportation and distribution.

Disclosure 305-5 Reduction of GHG emissions

Clariant was once again able to record a significant reduction of its energy consumption in 2017. All forms of energy, such as electricity, heat, cold, steam, as well as natural gas and the other primary fuels are included here. Almost all of the savings were the result of the measures initiated by the energy management program eWATCH. eWATCH is a Group-wide systematic, efficient, and coordinated energy management program. The program permanently records the whole energy consumption, analyzes the savings potentials, and enables the continuing usage optimization of the machines. Plants are being planned and utilized in the production process in such a way that they can be optimized continuously to achieve the best efficiency level of each individual usage. The lessons learned here help in the performance-optimized design of plants and in the selection of efficient components. Not only is eWATCH very interesting from an ecological point of view but also from an economic point of view because the program allows the evaluation of the cost-benefit ratio between investments and energy savings.

Disclosure 305-6 Emissions of ozone-depleting substances (ODS)

Ozone depleting substances are no more used. Cooling agents if relevant are now reported under greenhouse gases.

Disclosure 305-7 Nitrogen oxides (NO_X), sulfur oxides (SO_X), and other significant air emissions

Significant emissions of other inorganic pollutants such as SO2 (-30%) and NO_x (-27%) have been reduced since 2014.
