"Climate Action Tracker" which monitors the emission reduction pledges of different countries is a:
Correct Answer: Option A
The Climate Action Tracker (CAT) is an independent scientific analysis that monitors government climate action and assesses it against the Paris Agreement goals (limiting warming to well below 2°C, and ideally to 1.5°C).
It is a collaborative effort between Climate Analytics and NewClimate Institute, providing independent analysis to policymakers since 2009.
The CAT quantifies and evaluates climate change mitigation targets, policies, and actions. It also aggregates country-level actions to determine likely temperature increases during the 21st century using the MAGICC climate model.
CAT tracks 39 countries and the EU, covering approximately 85% of global emissions.
Therefore, the Climate Action Tracker is a database created by a coalition of research organizations.
