# CADS

Carbon emissions present a critical challenge, as excessive amounts of carbon dioxide contribute to global warming. The urgency of addressing this issue,  as confirmed by the [Intergovernmental Panel on Climate Change](https://www.ipcc.ch/) projections, is needed to restore balance. 

Agriculture, a significant contributor to greenhouse gas emissions, can harness carbon storage in soil. However, this requires overcoming challenges like heterogeneous data use and adopting emerging technologies for carbon estimation to create new value streams for farmers. [Carbon Assessment and Data Sharing (CADS)](http://cloud-5.bitp.kiev.ua/?p=1895\&lang=en) addresses these challenges by offering carbon footprint assessment and sound adjustment tools for agro-technological, organisational, and management decisions. 

The AgriModel tool within CADS provides carbon equivalent calculations based on verified algorithms, guiding farmers to identify their data needs for specific product development in the value chain. CADS leverages [i4Trust Building Blocks](https://github.com/i4Trust/building-blocks) to route and deliver data, enabling farmers to use existing and external data sources for carbon footprint assessment and mitigation. This allows farmers to upload data to the [FIWARE Orion Context Broker](https://fiware-orion.readthedocs.io/en/master/) via the API server, integrated with the iSHARE Satellite to verify the trusted participant lists. 

With adherence to [iSHARE specifications](https://dev.ishare.eu/), data-sharing intermediaries provide farmers access to carbon web dashboards using generated identities managed by CADS's Authorization Registry functions.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://i4trust.ishare.eu/open-call-1/cads.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
