A First Look at Biennial Transparency Reports Under the Paris Agreement

Parties to the Paris Agreement submit Biennial Transparency Reports (BTR) with information on mitigation, adaptation and support. By 31 December 2024, the deadline for submission of the first BTR, 86 Parties submitted such a report. Twelve Parties did not provide a BTR but submitted related information. Many Parties went beyond the mandatory requirements, in particular by reporting information on climate change impacts and adaptation, on loss and damage, and on support needed and received.

The BTRs that have been submitted can serve as good practice examples for Parties that are finalizing their reports. As submissions from many Parties are still pending, additional data sources may need to be used to provide a more complete picture of climate action and support under the Paris Agreement.

The submitted data on progress towards the implementation of Nationally Determined Contributions (NDC) informs about the status of mitigation actions and the progress of the global community to-wards the temperature goal of the Paris Agreement. A first screening of the information provided by some of the large emitters of greenhouse gases suggests that additional efforts are needed to meet their 2030 NDC targets.
