This Second National Communication of The Republic of Trinidad and Tobago focuses on the compilation and analysis of the National Inventory of greenhouse gases (GHGs), vulnerability and adaptation studies, mitigation options as well as on recommendations with respect to proper data collection and sharing, technology needs, capacity building, research and development constraints and challenges.

The Initial National Communication of The Republic of Trinidad and Tobago under the United Nations Framework Convention on Climate Change (UNFCCC) was prepared and published in 2001. Under Article 4 of the UNFCCC, the Republic of Trinidad and Tobago is required to publish, update periodically and make available to the Conference of Parties (COP) its National Inventory of GHGs and its national programmes to mitigate and adapt to climate change. Taking into account climate change scenarios, it is also expected that relevant future socioeconomic and environmental policies and actions would be developed and implemented.
