Key Performance Indicators to criteria 11 to 12

Key Performance Indicator GRI SRS-301-1: Materials used
The reporting organization shall report the following information:

a. Total weight or volume of materials that are used to produce and package the organization’s primary products and services during the reporting period, by:
i. non-renewable materials used;
ii. renewable materials used.

As a university, the Environmental Campus Birkenfeld uses materials to a much lesser extent than manufacturing companies. Nevertheless, the sustainable procurement of all materials and office equipment plays an important role and is included in the sustainability principles. anchored. This results, for example, in the priority given to recycled paper, the climate-neutral procurement of heat and electricity, the energy-efficient procurement of computer and laboratory equipment, and the sustainable construction and operation of buildings. A generally applicable procurement guideline is currently being drawn up that will further specify the sustainability criteria in procurement.

Key Performance Indicator GRI SRS-302-1: Energy consumption
The reporting organization shall report the following information:

a. Total fuel consumption within the organization from non-renewable sources, in joules or multiples, and including fuel types used.

b. Total fuel consumption within the organization from renewable sources, in joules or multiples, and including fuel types used.

c. In joules, watt-hours or multiples, the total:
i. electricity consumption
ii. heating consumption
iii. cooling consumption
iv. steam consumption

d. In joules, watt-hours or multiples, the total:
i. electricity sold
ii. heating sold
iii. cooling sold
iv. steam sold

e. Total energy consumption within the organization, in joules or multiples.

f. Standards, methodologies, assumptions, and/or calculation tools used.

g. Source of the conversion factors used.

As the only "Zero Emission University" in Europe, the campus obtains all its energy from renewable resources and is therefore CO2-neutral. Total energy consumption is made up of electricity and local heating. In the current german sustainability report, energy consumption is quantified and visualized in the chapter "Sustainable Resource Management". It presents the total energy demand in kWh divided into total heating and total electricity demand.
In addition to an explanation of the heating and cooling consumption, the communications building and the sports hall are presented in more detail as showcase projects with high energy efficiency and special ventilation technology.
Only in the area of mobility are fossil fuels still used to some extent, but here, too, the use of renewable energies is being promoted through the expansion of the electric car fleet and the construction of a solar carport at the environmental campus. 

Key Performance Indicator GRI SRS-302-4: Reduction of energy consumption
The reporting organization shall report the following information:

a. Amount of reductions in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples.

b. Types of energy included in the reductions; whether fuel, electricity, heating, cooling, steam, or all.

c. Basis for calculating reductions in energy consumption, such as base year or baseline, including the rationale for choosing it.

d. Standards, methodologies, assumptions, and/or calculation tools used.

In order to reduce energy consumption on campus, sustainability targets are regularly defined and their implementation monitored in addition to regular monitoring by the staff of the operations technology department. They serve to exploit the potential of the campus in the areas of energy-saving, energy efficiency, solar energy, biomass, waste, wastewater, and mobility. and to derive measures. In the current german Sustainability Report, the chapter "Sustainable resource management" and "Targets 2020" contains a number of examples as well as specific targets for reducing energy consumption.

Key Performance Indicator GRI SRS-303-3: Water withdrawal
The reporting organization shall report the following information:

a. Total water withdrawal from all areas in megaliters, and a breakdown of this total by the following sources, if applicable:
i. Surface water;
ii. Groundwater;
iii. Seawater;
iv. Produced water;
v. Third-party water.

b. Total water withdrawal from all areas with water stress in megaliters, and a breakdown of this total by the following sources, if applicable:
i. Surface water;
ii. Groundwater;
iii. Seawater;
iv. Produced water;
v. Third-party water, and a breakdown of this total by the withdrawal sources listed in i-iv.

c. A breakdown of total water withdrawal from each of the sources listed in Disclosures 303-3-a and 303-3-b in megaliters by the following categories:
i. Freshwater (≤1,000 mg/L Total Dissolved Solids);
ii. Other water (>1,000 mg/L Total Dissolved Solids).

d. Any contextual information necessary to understand how the data have been compiled, such as any standards, methodologies, and assumptions used.

The environmental campus also relies on modern technologies in the area of resource-conserving water use. The focus is on reducing the amount of drinking water and wastewater as well as on the increased use of rainwater. Water consumption is also reduced through water-saving faucets and waterless urinals. Detailed graphs and tables can be found in the current german Sustainability Report in the chapter "Sustainable resource management".

Key Performance Indicator GRI SRS-306-3: Waste generated
The reporting organization shall report the following information:

a. Total weight of waste generated in metric tons, and a breakdown of this total by composition of the waste.

b. Contextual information necessary to understand the data and how the data has been compiled.

Waste avoidance and separation is a component of the resource-saving operation of the Environmental Campus. Through a series of targeted measures, the volume of waste is reduced and waste is neatly collected separately. Thus, various separate collection containers for paper, plastic and residual waste are available at several locations. Used batteries, fluorescent tubes, and emptied containers for ink and toner are also collected, which feed the recyclable materials into a recycling loop. In the current german Sustainability Report, the handling of waste in the chapter "Sustainable resource management" in more detail.
