iv. Steam consumption: /

d.i. Electricity sold: /
ii. Heating sold: /
iii. Cooling sold: /
iv. Steam sold: /

e. Total energy consumption within the organization: 11,031,937 MWh

f. The indicators specified in this report under the heading of climate protection relate exclusively to materials and services purchased by the HOCHTIEF Group. In the HOCHTIEF Asia Pacific division, the indicators comply with the statutory requirements of the National Greenhouse and Energy Reporting Act 2007. 

We express our environmental indicators listed below in relation to Group work done in the year in question. The volume, type, location, and scope of the projects we have in progress during the year affect these indicators.

g. Sources for carbon conversion factors: GHG Protocol, DEFRA and Germany’s Federal Environmental Agency, NGER
 

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.

The nature, scope, and location of construction projects ongoing during the year have a direct impact on energy consumption levels and the emissions inferred from them. By their very nature, projects are not mutually comparable. Using a tunneling machine to bore through hard rock, for example, is much more energy-intensive than a building construction site operating on softer soil.

The total volume of energy consumption increased in 2018 compared with the prior year. This was largely driven by ongoing tunneling projects at CIMIC. In addition to that, HOCHTIEF’s order backlog rose during the reporting period to EUR 47.3 billion, corresponding to an increase of 7%. Only single examples can show reductions in energy consumption as a result of conservation and efficiency initiatives.

Key Performance Indicator GRI SRS-303-3: Water withdrawal

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.

a. Water consumption in 2018 amounted to a total of 21,123,194 m3 with a Group Coverage of 95%.
