Big changes are here. The 2025 update reimagines how we manage climate data to make it more reliable, easier to share, and ready for the future.

Here are the key updates:

Wider focus – CDMS now covers more than just storing data. It includes how data is used, shared, and protected—all guided by strong rules.

New and updated tools – Some parts have been added or changed. What used to be optional may now be required, especially to ensure quality and trust.

Data history is a must – We now need to clearly show where data comes from. This helps others trust the information and use it with confidence.

Follow global standards – The system now works better with other tools and organizations by aligning with international standards.

Always improving – This is a “living document” that will keep evolving as new tech and policies develop.

Why it matters – These changes help countries manage climate data better—for science, for planning, and for people.
