Opportunities and Challenges for Carbon Trading from Livestock Sector

ZusammenfassungMit diesem Beitrag schlagen wir einen zweistufigen Weg zu einer effektiven deutschen Klimapolitik vor. Die erste Stufe orientiert sich an der Schweizer CO2-Abgabe: Ab 2020 soll der Kohlendioxidausstoß im privaten Heizenergie- und Verkehrsbereich besteuert werden, da beide Sektoren nicht im EU-Emissionshandel erfasst werden. Wie im Schweizer Modell fließt das Steueraufkommen durch Transfers und Investitionen an die Bevölkerung zurück. Allerdings soll die direkte Rückerstattung auf die Hälfte der Steuereinnahmen beschränkt und auf das einkommensschwächste Drittel der Haushalte konzentriert werden. Die andere Hälfte soll zur Förderung des ländlichen ÖPNV und zur energetischen Sanierung von Mietshäusern eingesetzt werden. Damit wird Klimaschutz – ein Gebot intergenerationeller Gerechtigkeit – im Sinne einer Sozialen Marktwirtschaft umgesetzt: Der Klimaschutzbeitrag jedes Einzelnen orientiert sich auch an Leistungsfähigkeit und Bedürftigkeit. Ab 2030 sollte der zweite Schritt unseres Ansatzes einsetzen und das Steuermodell sukzessive in einen verbraucherbasierten Emissionshandel überführt werden. Ein funktionierendes Personal Carbon Trading System ist allerding technisch und rechtlich komplexer als eine CO2-Steuer. Die sofortige Umsetzung von Stufe eins schafft das nötige Zeitfenster für die Vorbereitung eines Zertifikatesystems für Heizenergie und Mobilität. Die oft angeführten Nachteile eines solchen Systems – hohe Transaktions- und Administrationskosten – halten wir aufgrund der Fortschritte in der Informationstechnologie bereits heute für händelbar. Dafür hätte ein solches System gegenüber einer Steuer folgende Vorteile: Es ist mit dem EU-ETS kompatibel, Emissionsziele werden sicher erreicht und jeder Verbraucher erkennt direkt, für welche CO2-Emissionen er persönlich verantwortlich ist.

Management Challenge

In 2019, Sri Lanka introduced two policies that referred to food waste and the need to reduce it. To understand key stakeholders’ readiness in this context, this study analyzed the food waste perceptions of private and public sectors in Colombo (open markets, supermarkets, hotels, restaurants, canteens, food caterers and key authorities). Interviews were carried out with operational managers and public officials, as well as other stakeholders who have roles in food waste redistribution and reuse, such as NGOs and the livestock sector. So far, the food-waste-related policy recommendations lack an operational inter-institutional home which can build on measures, like standards, regulations and incentives. Thus, most food waste reduction initiatives are initiated by NGOs or by the private sector, e.g., by larger hotels and supermarket chains. These entities were ready to lead by example, based on the understanding that urban food waste is an internal (financial) management challenge. Among smaller local entities, food waste was perceived more as an external issue to be handled by the city’s waste collection services. Although perceptions varied between entities generating smaller or larger quantities of food waste, there was general agreement that suboptimal capacities and mechanisms to quantify, monitor and cost food waste generation appeared to be obstacles for in-depth awareness creation and action. There was significant interest in communication platforms for cross-sectoral learning, win/win collaborations with reliable collection (reuse) services that are currently operational, such as those provided by piggeries, as well as surplus redistribution initiatives if food safety and related liabilities can be addressed effectively.

Nanotechnology is one of the major advanced technologies applied in different fields, including agriculture, livestock, medicine, and food sectors. Nanomaterials can help maintain the sustainability of the livestock sector through improving quantitative and qualitative production of safe, healthy, and functional animal products. Given the diverse nanotechnology applications in the animal nutrition field, the use of nanomaterials opens the horizon of opportunities for enhancing feed utilization and efficiency in animal production. Nanotechnology facilitates the development of nano vehicles for nutrients (including trace minerals), allowing efficient delivery to improve digestion and absorption for better nutrient metabolism and physiology. Nanominerals are interesting alternatives for inorganic and organic minerals for animals that can substantially enhance the bioavailability and reduce pollution. Nanominerals promote antioxidant activity, and improve growth performance, reproductive performance, immune response, intestinal health, and the nutritional value of animal products. Nanominerals are also helpful for improving assisted reproductive technologies (ART) outcomes by enriching media for cryopreservation of spermatozoa, oocytes, and embryos with antioxidant nanominerals. Despite the promising positive effects of nanominerals on animal performance and health, there are various challenges related to nanominerals, including their metabolism and fate in the animal’s body. Thus, the economic, legal, and ethical implications of nanomaterials must also be considered by the authority. This review highlights the benefits of including nanominerals (particularly nano-selenium and nano-zinc) in animal diets and/or cryopreservation media, focusing on modes of action, physiological effects, and the potential toxicity of their impact on human health.
