1. Accounting and Accountability: Towards a Credible and Robust Carbon Market – The Blockchain Potential

2. Blockchain Technology – What is it?
A new kind of decentralized database;
Data is not stored centralized but distributed over many participating computers;
In principle, all transactions in the network are transparent for its participants;
All participants continuously monitor and record transactions and check database records for coherence;
This process is automatized through a network protocol – similiar to HTTP.

3. Blockchain Technology – Hash

5. Using blockchain technology for Accounting within Art. 6
Potential elements of Art. 6
Potential role of blockchain technology
Consistency with Art. 13 e.g. in accounting between Parties natl. GHG inventory, NDC and international transfers
WHAT: Integration of inventory, NDC data and international transfers from Parties in a joint blockchain network.
WHY: Allows e.g. for automatic check if unit is from in-/ outside Party’s NDC scope, rule out double counting or perform corresponding adjustments
Transparency in tracking and promoting sustainable development of ITMOs
WHAT: Integration of nationally determined parameters
WHY: Additional ITMO information on sector, standard used, etc. -> unit quality and added value
Managing project/programme cycle (LoA, validation, registration, verification, issuance, renewal)
WHAT: Integration of standardized project data “inscribed” in a joint blockchain network.
WHY: Allows e.g. for automated issuance of units via smart contracts
