Erdüberlastungstag 2022: Was ist notwendig, um den Tag zu verschieben?
Sam Wheeler • May 04, 2022
Der Erdüberlastungstag kennzeichnet das Datum eines laufenden Jahres, an dem die menschliche Nachfrage nach nachwachsenden Rohstoffen und Dienstleistungen die Kapazität der Erde hinsichtlich der jährlichen Reproduktion dieser Ressourcen übersteigt.
Der Überlastungstag eines Landes bezeichnet jenes Datum, auf welches der Erdüberlastungstag fallen würde, wenn die gesamte Menschheit genauso konsumiert wie die Menschen in diesem Land.
In Deutschland ist dies im Jahr 2022 der heutige Tag: der 4. Mai. Fünf Monate nach Jahresbeginn hätten wir bereits die Ressourcen der Erde aufgebraucht, wenn der ganze Planet diese so konsumieren würde wie wir.
In der untenstehenden Abbildung können Sie erkennen, wo wir uns dieses Jahr im Vergleich mit anderen Ländern befinden.
Die Länder der Europäischen Union sind alle in der ersten Jahreshälfte zu finden, wobei Rumänien mit dem 11. Juni den spätesten Zeitpunkt aufweist. Im Vergleich zu unseren Nachbarn in der EU liegt Deutschland im Mittelfeld, jedoch stellen die Zahlen klar, dass es in der ganzen Region noch viel zu tun gibt.
Das Bauwesen ist für 39% aller CO2-Emissionen auf der Welt verantwortlich, wobei davon 28% für betriebliche Emissionen (Energiebedarf für das Beheizen, Kühlen und Beleuchten von Gebäuden) anfallen. Die verbleibenden 11% gehen auf die sogenannte graue Energie oder den indirekten Energiebedarf für „Vorprodukte“ der Rohstoffgewinnung und den Energieeinsatz aller angewandten Produktionsprozesse während des gesamten
Lebenszyklus eines Gebäudes zurück.
Unsere 3 besten Tipps für den Gebäudesektor wären:
- Wiederverwendung von bestehenden Gebäudestrukturen an Stelle des Baus neuer Gebäude: Ganz egal ob sich um die Renovierung Ihres bestehenden Gebäudes zur Erhöhung der Energieeffizienz (Heiz-, Belüftungs- und Klimaanlagen sowie Beleuchtungs- und Wasserversorgungssysteme) oder die adaptive Wiederverwertung zum Erhalt von historischen Gebäuden handelt, es ergeben sich in beiden Fällen bedeutende Zeit-, Emissions- und Kosteneinsparungen. Sogar wenn es sich um den Bau eines neuen „grünen“ Gebäudes handeln sollte, ist die Nachnutzung eines bereits bestehenden Gebäudes im Zeitverlauf fast immer nachhaltiger, wenn man den Lebenszyklus und die graue Energie berücksichtigt.
- Bauen mit wiederverwendeten oder recycelten Materialien: Viele Baumaterialien können wiederverwendet werden. Hierzu gehören unter anderem Beton, Ziegelsteine/Blöcke, Holz, Pflastersteine, Glas und Metalle. Wenn Baumaßnahmen erforderlich sind, sollte der Fokus auf Ressourceneffizienz gelegt werden, indem man Abfall reduziert, Materialien wiederverwertet oder recycelte Materialien bzw. mittels kohlenstoffarmer Technologien hergestellte Materialien verwendet.
- Völliger Verzicht auf fossile Energieträger: Dies scheint vielleicht ein großer Sprung zu sein, aber die Reduzierung der Emissionen zum Erreichen unserer Nettonullenergie-Ziele (und wiederum zur Verlangsamung des Klimawandels sowie zur Senkung des Bedarfs an natürlichen Ressourcen) erfordert die Nutzung von kohlenstoffarmen Energieträgern als Ersatz für fossile Brennstoffe. Der Wechsel hin zu sauberen Energieanbietern oder die Investition in erneuerbare Energien am eigenen Standort können sowohl die Kosten auf lange Sicht senken als auch den CO2-Fußabdruck deutlich reduzieren.
Die Kernbotschaft besteht darin, dass bereits viele Lösungen bestehen und weitere noch entwickelt werden können, um den Ziel der Klimaneutralität näher zu kommen und den Erdüberlastungstag nach hinten zu schieben, auch wenn die Ressourcen unseres Planeten begrenzt sind.

While many companies are already taking comprehensive measures to minimise the effects of climate change as far as possible, it is also true that climate change is inevitable in the near and distant future. This has already become noticeable in large parts of Germany with an increase in extreme weather events such as the flood disaster in the Ahr valley in 2021, numerous hot summers in recent years, or the constant rain and flooding at the beginning of this year. Companies should therefore address the risks that could arise from climate change and the associated increase in extreme weather events, for example at their different sites, as early as possible.
Registration is now open for the GBCI Circle event for 2024. You can register here. EnviroSustain is proud to once again be a sponsor of this event which will be held in Athens, Greece. The event will run from the 17-19 April and the three days will be packed with a welcome reception, sustainable building tours, experiences, and learning sessions. After such a great experience last year in Barcelona , we can’t wait to travel with the team again. As we avoid air travel as part of our ESG Policy, the ES team will be travelling to Athens by land and sea over the course of two days! This involves the night train from Munich to Roma (or alternatively to Bologna), train to Bari, then the ferry overnight from Bari to Patras and to finish the bus to Athens. We look forward to sharing our journey with you on social media. GBCI Circle is designed to provide networking opportunities and education sessions for Europe's LEED consultants, property owners and managers, building experts and consultants and all of those interested in sustainability within real estate. The 2024 program focuses on the future of Healthy Human Habitat Venues include The Piraeus Tower (pursuing LEED Platinum and WELL certification), The Lighthouse (LEED Platinum), The Ellinikon (pursuing LEED, WELL and SITES), The National Gallery of Art (2 x LEED Silver certifications).
With the start of a new year comes the beginning of a new GRESB reporting period. EnviroSustain has been supporting clients with GRESB submissions for almost a decade now and we are pleased to see participation growing. The GRESB portal will open on 1st April but now is the time to begin prepping your team and collecting data. As ESG reporting gains more momentum in the mainstream, changes are needed to keep up with current developments. The Real Estate and Infrastructure Standards Committee works to gather feedback and make recommendations on changes to the GRESB Foundation Board.
The annual Global Risk Report published by the World Economic Forum (WEF) presents a comprehensive analysis of current global challenges. In its report published in January of this year, the WEF warns of a "foreseen duo of dangerous crises", referring to the duality of climate and conflict-related challenges. Respondents from academia, business, government, the international community and civil society see climate change-related risks in particular as a key global challenge in the long term. According to the survey, the four most highly rated risks over the next 10 years are: extreme weather events, critical changes to earth systems, loss of biodiversity and the collapse of ecosystems. In addition, current crises and conflicts such as inflation, the war in Ukraine and the conflict between Israel and Palestine make many respondents pessimistic about the coming years. If implemented consistently, ESG guidelines can help to reduce the negative impact of companies on the environment and thus mitigate climate change-related risks by creating a sustainable business environment. In 2024, numerous new EU regulations will come into force to make ESG reporting more transparent and standardised. The aim is to oblige companies to be more transparent and accountable with regard to their environmental impact.
We are all increasingly aware of the pressing need for environmental sustainability and as biodiversity disclosures gain momentum , the Task Force on Nature-related Financial Disclosures (TNFD) serves as a blueprint for integrating nature-related disclosures into decision making and existing mandatory reporting requirements. TNFD, like the Task Force for Climate-related Financial Disclosure (TCFD), operates as a voluntary disclosure framework. However, we hope that some governments and regulatory bodies will begin to incorporate TNFD recommendations into mandatory reporting frameworks. For organisations, voluntary adoption of TNFD is a proactive step towards staying ahead of potential regulatory changes and investor demands. By embracing TNFD early, companies can gain a competitive advantage and demonstrate their commitment to environmental responsibility.
With all the good biodiversity gives us and our environment, you would hope that it is sufficiently protected and supported by legislation. Not only in Europe, but also worldwide. As part of the European Green deal approved in 2020, the Nature Restoration Law is the first of its kind to cover the entire continent in Europe. Sadly, 80% of Europe’s natural habitats are in poor condition, but the proposed Nature Restoration Law will help to turn the tide when it comes to the protection and rejuvenation of European biodiversity by two 2030 and 2050 milestones.
‘Biodiversity’ is known as ‘the variability among living organisms from all sources including, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; including diversity within species, between species, and of ecosystems’. According to this report by the World Economic Forum, Biodiversity equals around $44 trillion in economic value (more than 50% of global GDP), making biodiversity one of Earth’s most valuable assets. Despite the massive amount of value biodiversity provides us, our global loss of biodiversity over the past 50 years has been significant, and 80% of that global biodiversity loss is caused by the built environment, agriculture, and energy/extractives. Sadly, a byproduct of advancing our own environments is that we’re destroying the Earth’s natural ones at the same time. This is because of many factors, and IPBES notes five main drivers: Habitat loss Over-exploitation of natural resources Spread of invasive species Climate change Pollution
Amongst all the policies and jargon out there, it’s easy to forget why it all matters and what the overarching goal is, so let’s take a moment to think about it. The pressure on Earth’s resources is becoming unbearable. Every year, Earth Overshoot Day (the annual date that marks the point when humanity uses more biological resources than the Earth can regenerate within a given year) creeps earlier and earlier. Extreme heat events are becoming more common with forest fires on the rise; species are dying due to habitat loss and food scarcity; our seas are rising and warming leading to devastating floods and enforced migration. All of this and we’re still projected to exceed 1.5 degrees of global warming, despite the 2015 Paris Agreement and subsequent UN promises. In short, we need action, and we need it yesterday.
In February 2023, EnviroSustain announced a long-term partnership with Rewilding Europe. This collaboration will see a portion of the EnviroSustain turnover supporting rewilding initiatives for the next ten years, as well as pro bono advice on rewilding-related buildings in the network- such as new offices and rewilding centres. In June, Dr. Birgit Memminger-Rieve, MD at EnviroSustain, and Ingemar Hunold, Partner at EnviroSustain, met with the Rewilding Oder Delta team to provide support and advice for their newly established centre.
