          Zusammenfassung

          Aufgrund der Größe der betroffenen Landflächen, den bei ihrer Nutzung emittierten und sequestrierten Treibhausgasen (THG) und des teilweise ungünstigen Zustands von Böden in Hinblick auf ihren Gehalt an organisch gebundenem Kohlenstoff (C) kommt der Landnutzung a priori eine wichtige Rolle bei Mitigationsbemühungen zu. Zur Minderung des Klimawandels ist eine Verringerung der atmosphärischen CO2-Konzentration erforderlich, die durch eine Abnahme der THG-Emissionen und durch Aufnahme und langfristige Speicherung von atmosphärischem Kohlenstoff in Biomasse und Boden erreicht werden kann (Chenu et al., 2019; Mayer et al., 2018; Paustian et al., 2016; Vos et al., 2018). Der Erhaltung bzw. idealerweise Erhöhung der organischen Substanz des Bodens durch geeignete Bodenschutzmaßnahmen kommt entscheidende Bedeutung zu.

            Reducing food’s environmental impacts through producers and consumers

            Food's environmental impacts are created by millions of diverse producers. To identify solutions that are effective under this heterogeneity, we consolidated data covering five environmental indicators; 38,700 farms; and 1600 processors, packaging types, and retailers. Impact can vary 50-fold among producers of the same product, creating substantial mitigation opportunities. However, mitigation is complicated by trade-offs, multiple ways for producers to achieve low impacts, and interactions throughout the supply chain. Producers have limits on how far they can reduce impacts. Most strikingly, impacts of the lowest-impact animal products typically exceed those of vegetable substitutes, providing new evidence for the importance of dietary change. Cumulatively, our findings support an approach where producers monitor their own impacts, flexibly meet environmental targets by choosing from multiple practices, and communicate their impacts to consumers.
