Katowice Climate Package
Definition
The Katowice Climate Package is the bundle of decisions adopted at the 24th Conference of the Parties (COP24, Katowice, 2018) that operationalised most of the 2015 Paris Agreement. Often called the Paris Rulebook, it set common modalities, procedures and guidelines for nationally determined contributions, the enhanced transparency framework, the global stocktake, adaptation communications, finance reporting and the implementation and compliance committee.

Overview
What it means
The Paris Agreement established goals but left their machinery to later negotiation. Katowice supplied most of that machinery — notably common rules for how countries report emissions, progress and support under the transparency framework — so that pledges could be compared, tracked and reviewed.
Agreement on international carbon-market rules (Article 6) was not reached there and was only finalised at COP26 in Glasgow in 2021.
How it is used
Parties apply the Katowice guidelines when preparing NDCs, biennial transparency reports and long-term strategies, and when participating in the global stocktake; the package underpins the Paris Agreement's accountability architecture.
Why it matters
Without the rulebook, the Paris Agreement would be aspirational rather than implementable; Katowice made collective monitoring of climate action possible.
