Thunis, P. (author), Clappier, A. (author), Pisoni, E. (author), Bessagnet, B. (author), Kuenen, J. (author), Guevara, M. (author), Lopez-Aparicio, S. (author)Some studies show that significant uncertainties affect emission inventories, which may impeach conclusions based on air-quality model results. These uncertainties re sult from the need to compile a wide variety of information to estimate an emission inventory. In this work, we propose and discuss a screening method to compare two emission...article 2022

(author)To conserve resources and enhance the environmental performance, China has launched the “Zero waste” concept, focused on reutilization of solid waste and recovery of materials, including copper. Although several studies have assessed the copper demand and recycling, there is a lack of understanding on how different waste management options would...article 2022

Schwarz, A.E. (author), van Emmerik, T. (author)Pollution of plastics to the environment is uninhibitedly increasing, from densely populated city centers to remote oceans (Lebreton et al. 2018; van Emmerik et al. 2019b). Causes for this increase are a combination of a growing world population, rising plastic consumptions, and poor waste management (Lebreton and Andrady 2019; Borrelle et al....bookPart 2022

Sun, Z. (author), Behrens, P. (author), Tukker, A. (author), Bruckner, M. (author), Scherer, L. (author)Key biodiversity areas (KBAs) are critical regions for preserving global biodiversity. KBAs are identified by their importance to biodiversity rather than their legal status. As such, KBAs are often under pressure from human activities. KBAs can encompass many different land-use types (e.g., cropland, pastures) and land-use intensities. Here, we...article 2022

(author)One of the key challenges for plastics in a circular economy is its degradation during use, washing and reprocessing. The reduced quality of recycled plastic waste leads to its use in inferior applications. This study presents a novel quality model which incorporates degradation, degree of mixing and contaminations. The model estimates a single...article 2022

Pandey, S. (author), Houweling, S. (author), Segers, A. (author)Atmospheric inversions are used to constrain emissions of trace gases using atmospheric mole-fraction measurements. The four-dimensional variational (4DVAR) inversion approach allows optimization of emissions at a higher temporal and spatial resolution than ensemble or an alytical approaches but provides limited opportunities for scalable...article 2022

(author)Coal mines are globally an important source of methane and also one of the largest point sources of methane. We present a high resolution 0.1° × 0.1° bottom-up gridded emission inventory for methane emissions from coal mines in India and Australia, which are among the top five coal producing countries in 2018. The aim is to reduce the...article 2022

(author)Atmospheric levels of ammonia (NH3) have substantially increased during the last century, posing a hazard to both human health and environmental quality. The atmospheric budget of NH3, however, is still highly uncertain due to an overall lack of observations. Satellite observations of atmospheric NH3 may help us in the current observational and...article 2022
