This 2013 Emerging Environmental Issues publication presents 12 monthly bulletins in a single document, allowing readers to note and assess significant environmental events that took place that year. UNEP’s GEAS team carefully identified and selected these monthly issues by continuously scanning the scientific literature, focusing on policy relevant environmental hotspots, environmental science, and near real-time environmental hazards. They are organized around UNEP’s five themes: environmental governance, harmful substances and hazardous wastes, ecosystem management, climate change, disasters and conflicts, and resource efficiency. Each bulletin acknowledges UNEP’s team of authors and provides a full list of the scientific literature referenced
