# Increasing transparency in carbon markets with Isometric's API

Improved access to public Registry data, providing open data the market needs

Isometric’s mission is to rebuild trust in carbon markets so carbon dioxide removal (CDR) can scale—responsibly and fast—to the level the planet needs. Transparency is necessary to achieve this mission. Trust in the market can only be established with clear, accessible and accurate data about the scientifically rigorous carbon removal credits Isometric verifies and issues.

For carbon markets to work effectively, all participants—buyers, suppliers, and intermediaries—must have reliable access to information about the carbon credits being used in the market. Recent updates to [Isometric’s API](https://docs.isometric.com/introduction) improve access to public [Registry](https://registry.isometric.com/) data, making detailed data about Isometric credits—and the projects behind them—more accessible.

There are three key improvements to the API that make Isometric data easier to access and understand, marking a significant step toward providing the open data the market needs.

1. **Enhanced Endpoints**: We've added endpoints to all categories of Registry data, allowing users to instantly fetch data-rich lists that detail the suppliers, projects, issuances, deliveries, transfers, and retirements of all Isometric credits.
   
2. **Data Enrichment with LCA**: The data provided within these endpoints now includes Life Cycle Assessment (LCA) data on individual credit batches, enabling users to visualize removal data.
   
3. **Efficient Credit Transactions**: The Isometric API facilitates credit transactions efficiently, allowing users to view available credits and filter the dataset. This functionality enhances the traceability of credit movements.

A number of leading carbon data providers, such as [CDR.fyi](https://www.cdr.fyi/), [MSCI](https://www.msci.com/our-solutions/climate-investing/carbon-markets), and [Sylvera](https://www.sylvera.com/), are now leveraging Isometric’s new API features. For example, CDR.fyi’s integration allows them to display more granular detail on projects and orders.

Isometric has also partnered with key platforms, such as [CEEZER](https://www.ceezer.earth/), to provide detailed credit information. Hannes Nützman, Co-Founder and Chief Product Officer of CEEZER, commented on the partnership, emphasizing the importance of open access to structured data to uphold the integrity of the voluntary carbon market.

Isometric partners can now regularly sync Isometric data across suppliers and credits, enhancing analysis through proprietary systems and facilitating comparisons across the CDR industry. By collaborating in this way, crucial data about CDR can reach a wide audience and contribute to a more informed and efficient carbon market. These improvements and partnerships cement Isometric’s data as a foundational resource for the CDR industry, fostering transparency and accountability.
