Scientific Opinion Paper: Resource-Efficient Pathways towards Greenhouse Gas- Neutrality (RESCUE)

The RESCUE study describes in six scenarios possible development paths towards a resource-efficient and greenhouse-gas (GHG) neutral Germany until 2050. The GreenSupreme scenario achieves the reduction of emissions along a global 1.5 °C path towards GHG-neutrality by 2050, while at the same time substantially lowering Germany’s material footprint. This publication discusses possible synergies and overlaps of the transformation areas within RESCUE and the elements of the recently published “European Green Deal”. It is hoped to inform stakeholders (e.g., governments, businesses, civil society, and science) with an interest in transformation pathways until 2050. Veröffentlicht in Scientific Opinion Paper.

Offizielle Eröffnung des Parks Bay South in Singapur

Am 29. Juni 2012 wurde in Singapur die 54 Hektar große Parklandschaft Bay South im Hafenstadtteil Marina Bay feierlich eröffnet. Herzstück sind sogenannte Supertrees, futuristische Baumriesen aus Metall und Beton, mit Höhen von 25 bis 50 Metern, die mit verschiedenen Pflanzenarten begrünt wurden. Der moderne Park ist die größte von drei Grünanlagen, die in den vergangen Jahren rund um das Hafenviertel unter dem Namen "Gardens by the Bay" entstanden sind. Zwei gigantische Gewächshäuser wurden im Bay South für Besucher geöffnet: Der Flower Dome und der Cloud Forest.

Erste kommerzielle CO2-Filteranlage der Welt ist in Betrieb gegangen

Am 31. Mai 2017 ging die erste kommerzielle CO2-Filteranlage der Welt in Betrieb. Sie steht in Hinwil im Schweizer Kanton Zürich auf dem Dach einer Müllverbrennungsanlage. Die vom Zürcher Startup-Unternehmen Climeworks entwickelte Anlage soll pro Jahr 900 Tonnen CO2 aus der Umgebungsluft abscheiden. Das so gewonnene Treibhausgas wird an Kunden verkauft. Potenzielle Kunden sind Unternehmen, die ihre CO2-Bilanz verbessern wollen – aber auch Gemüsehersteller. Bereits heute wird ein Gewächshaus in der Nachbarschaft von Climeworks mit dem abgeschiedenen CO2 versorgt. Das Treibhausgas kann das Wachstum von Gemüse beschleunigen.

EU verbessert den Schutz der Bienen in Europa durchweitere Maßnahmen bei Pestiziden

Am 16. Juli 2013 haben die Experten der Mitgliedstaaten auf ihrer Sitzung im Ständigen Ausschuss für die Lebensmittelkette und Tiergesundheit einen Vorschlag der Kommission zur Beschränkung der Verwendung von Fipronil gebilligt. Dieser Vorschlag folgt einer wissenschaftlichen Risikobewertung durch die Europäische Behörde für Lebensmittelsicherheit (EFSA)vom 27. Mai 2013, in der festgestellt wird, dass Saatgut, das mit Fipronil enthaltenden Pestiziden behandelt wurde, für die Honigbienenpopulation in Europa ein akutes Risiko darstellt. Die Maßnahmen : Beschränkung der Feldfrüchte, deren Saatgut mit Fipronil behandelt werden darf; Zulassungen dürfen erteilt werden für die Behandlung von Saatgut, das nur in Gewächshäusern ausgesät wird. Diese Ausnahmeregelung gilt allerdings nicht für Porree/Lauch, Schalotten, Zwiebeln und Kohlgemüse, die weiterhin im Freiland gesät werden dürfen, da sie vor der Blüte geerntet werden; die Behandlung von Mais- und Sonnenblumensaatgut ist nicht mehr zulässig; Überprüfung der Beschränkungen innerhalb von 2 Jahren durch die Kommission. Die Beschränkungen gelten dann ab dem 31. Dezember 2013.

Greenhouse - Gas - Neutrality in Germany until 2050

The success of climate and natural resource protection depends amongst others on the expansion of renewable energies. The policy paper describes the central results of the RESCUE study as well as the challenges and steps required to expand renewable energies in order to achieve greenhouse gas neutrality, and for Germany to make an appropriate contribution to the Paris Climate Agreement.

Detailed analyses of the system comparison of storable energy carriers from renewable energies

In the course of the transformation to a greenhouse gas-neutral society in the second half of the 21st century, the use of synthetic energy carriers based on renewable electricity or biomass is under discussion. This project evaluates the environmental impacts of technical and logistical options for the generation of such energy carriers on the basis of environmental impact categories such as global warming potential, acidification or land use. The production of five products (Fischer-Tropsch fuels, methanol, synthetic natural gas, biomethane and hydrogen) was examined on the basis of various process steps/procedures and their current and future technical data. By using regional factors for Germany, Europe and the Mediterranean region - like the availability of renewable energy sources such as wind or PV and of raw materials such as carbon or water as well as transport routes to Germany - these processes were combined to form supply paths for these energy carriers. Using the life cycle assessment method, the environmental effects were analysed for today and 2050. In addition, the costs for plant construction and operation were estimated. As a result, synthetic energy carriers generally have a significantly lower global warming potential than today's fossil reference products due to the use of renewable energies. However, the production of electricity generation plants and associated economic processes - such as steel and cement production - can still make a relevant contribution to the global warming potential if they are not also greenhouse neutral. At the same time, it is this production of the necessary plants that leads to (sometimes significantly) increased burdens compared with the fossil reference in almost all other impact categories, most notably in terms of water and land use. This study therefore also provides indications of which environmental impacts must be further reduced in the future. Quelle: Forschungsbericht
