Title:	Graue Emissionen im Bauwesen - Bestandsaufnahme und Optimierungsstrategien
Abstract:	Die menschengemachten CO2-Emissionen sind weiterhin viel zu hoch, um die 2015 im Pariser Klimaabkommen gesetzten Ziele - nämlich eine Beschränkung der Erderwärmung auf 1,5 °C im Vergleich zum vorindustriellen Zeitraum - zu erreichen. Das Bauwesen spielt dabei eine besondere Rolle, denn es ist anteilig der größte Emittent des klimaschädlichen Gases CO2. Der vorliegende Aufsatz untersucht deshalb Umfang und Reduktionspotenzial der grauen Emissionen, die für Herstellung, Einbau und Abbruch von tragwerksrelevanten Bauelementen in Deutschland entstehen. Ziel ist es hierbei, einzuhaltende Grenzwerte aufzuzeigen und zu erläutern, welche Maßnahmen bereits in frühen Planungsphasen eine deutliche Reduktion der grauen Emissionen möglich machen. Embodied emissions in the building sector The global, manmade CO2-emissions remain on a high level. Too high to meet the objectives that were set in the Paris agreement on climate change in 2015. Reducing the global warming to 1,5 °C compared to preindustrial times seems to be a hopeless endeavor. When it comes to a sustainable future, the building industry is the most critical sector since it emits the most climate harming CO2-emissions. In this paper we address the embodied emissions that occur with production, implementation and disassembly of construction materials in Germany. It is shown what limits must not be overtaken and which manners enable a reduction of emissions in early planning phases.
