In fulfilment of the common commitment under the United Nations Framework Convention on Climate Change and the Paris Agreement, Cuba has produced its first National Greenhouse Gas (GHG) Inventory document, covering the period 1990–2022.

This inventory establishes a balance between the quantity of greenhouse gases emitted and removed from the atmosphere by a country (Party) for a specific location and time period, generally corresponding to a calendar year.

While delivering a lecture on the topic at the 2025 Contat Atmospheric Pollution Workshop Seminar, Dr. Rosmary López Lee, Senior Researcher and Head of the Atmospheric Pollution and Chemistry Centre (CECONT) at the Institute of Meteorology, emphasised the report’s importance for decision-making to implement climate change impact mitigation measures. It identifies the sectors and activities responsible for the main GHG emissions and absorptions.

It also enables the establishment of concrete mitigation goals and targets, assessment of the country’s environmental status, design of efficient climate policies, contribution to sustainable development, and creation of decarbonisation strategies.

The inventory revealed that the sectors with the highest greenhouse gas emissions in the largest of the Antilles are, in order: energy, agriculture, and waste – generated by numerous sources, stressed the Professor at the Higher Institute of Technologies and Applied Sciences (Instec).

The monitored pollutants were carbon dioxide, methane, and nitrous oxide, with the first being the primary GHG emitted.
