On a Road to Net Zero Emissions From the Editor

Today, sustainability is the buzz word and countries around the world are working together to address a common challenge, the climate change. The latest report by the Intergovernmental Panel on Climate Change indicates that any further increase of global temperatures would have adverse impact on human health, environment, agriculture, water availability, and multitude of other Earth related problems. Therefore, worldwide efforts are underway, including international protocols and agreements (e.g., The Paris Agreement of 2015), aiming to limit global warming by the end of the 21st century to well below +2°C, preferably to +1.5°C.
