# Policies The process to create credit or offset claims can be validated and verified to be turned into a product that is called measurement, reporting, and verification data, also known as MRV data. Today, this process of collecting the supporting data for these carbon credits or offsets is heavily manual and prone to errors due to poor data quality, a lack of assurance, potential double counting, greenwashing, and an overall lack of trust. This is where Guardian, which leverages a Policy Workflow Engine, ameliorates the issue with the current processes. The dynamic Policy Workflow Engine can mirror the standards and business requirements of regulatory bodies. A Policy Workflow Engine is a software application that manages business processes based on business rules and business data which are defined within the context of a specific policy. A policy workflow engine, therefore, manages and monitors the state of required policy actions and the required information flow in a policy grouped into a policy workflow, and determines which are the next policy actions based on the state of a policy workflow. The policy actions may be anything from saving an application form in a document management system to sending a reminder e-mail to users or escalating overdue items to management. Policy Workflow Blocks enable different business logic to exist within the Guardian’s policy workflow engine. --- # Agent Instructions: 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.
