As the global focus on achieving carbon neutrality intensifies, countries in the Asia–Pacific region have launched ambitious initiatives to enhance their greenhouse gas (GHG) monitoring capabilities. A significant number of atmospheric GHG monitoring stations have already been or are in the process of being set up to support the evaluation of GHG emissions.

However, significant challenges remain with respect to developing comprehensive monitoring networks and reducing uncertainties in GHG emission estimates. This special issue seeks to foster collaboration and stimulate advancements in GHG monitoring, with the goal of contributing to the development of a robust GHG monitoring system that supports carbon neutrality efforts in the Asia–Pacific region and beyond.

The SI includes original research, reviews, and case studies that focus on atmospheric GHG monitoring and contribute to a deeper understanding of GHG emission estimates, mitigation strategies, and overall monitoring efforts.

Review process: This inter-journal special issue co-lists papers of different journals. Thereby, each paper was submitted to 1 particular journal and underwent the regular interactive peer-review process of that journal. Depending on the journal, the peer review was handled by regular members of the editorial board and/or by guest editors designated by the journal’s chief/executive editors.
