The German government's goals of achieving greenhouse gas neutrality by 2045 are just one example of the efforts being made by Europe and many parts of the world to reduce greenhouse gas emissions globally. The construction industry is responsible for around 40% of total CO2 emissions worldwide. In Germany, the aim is to achieve a 65% reduction by 2030 compared with 1990 levels.
Massive efforts are needed to achieve these ambitious goals. The construction industry can and must play a central role in this - this was a clear statement that was reflected throughout the colloquium's lecture program.
Xella, as a globally active building materials manufacturer, takes this role very seriously and intends to lead the way. Thus, Xella offered delegates from research and science, the manufacturing industry, as well as plant manufacturers together with suppliers from the aerated concrete and sand-lime brick industry an ideal platform to discuss current developments with the symposium.
In seven keynote presentations, as well as 14 technical papers, topics such as political objectives, decarbonization of construction and raw materials, circularity, recarbonization, sustainability in building construction and differences in the global implementation of climate targets were discussed.
The goal: more efficient and sustainable products
Torsten Schoch, managing director of Xella Technologie- und Forschungsgesellschaft mbH, opened the colloquium and welcomed the guests from Europe, Asia, and North and South America. He called for an intensive exchange and was sure that the results of this day will help to make the production, processing and recycling of aerated concrete and sand-lime bricks more efficient and to improve them.
Christophe Clemente, CEO of Xella Group, took the floor and made it clear that the considerable share of global greenhouse gas emissions caused by the construction industry is a great challenge, but also an opportunity at the same time. The Xella Group is taking responsibility and has set itself the goal of reducing the company's CO2 emissions intensity by 30% by 2030 (from 2019) and making its building materials more efficient, sustainable, and affordable.
Additional keynotes from Henning Ellermann, Member of the Executive Board and Head of Energy Efficiency in Buildings from the German Corporate Energy Efficiency Initiative (DENEFF e.V.), Dr. Stephan Richardson, Director Europe Regional Network of the World Green Building Council and Hildegard Bentele, Member of the European Parliament provided insights into overarching strategies on how the building sector can become more sustainable in the future and which paths can be pursued to achieve this goal. Key among them: the European Green Deal, an initiative of the EU Commission to become the first climate-neutral continent.
