+# GCR Policy Template Methodologies
+
+Global Climate Registry is a carbon registry which leverages Hedera Guardian as a core piece of technology to create customised policies/methodologies and onboard different players in the development of a carbon offset project such as project developers, auditors, credit buyers etc. GCR has create a template policy with a fixed steps flow so that different methodologies can be onboarded by change of schemas.
+
+GCR has created a [Middleware API](https://documenter.getpostman.com/view/23057894/2sA3Bj8ZD8) in order to perform policy operations in Guardian technology and further functionalities using hedera SDK. Apart from registry, GCR has also built social infrastructure to bring the carbon community together on a platform.
+
+## GCR policy template
+
+GCR platform is a one stop solution for carbon offset project creation. It has a step by step process to create a project and onboard different players/users involved in the project's development. Please view our policies subdirectory to get details on specific methodologies.
+
+### Every policy requires three user roles and one optional user role: 
+- Standard Registry (Global Climate Regitry)
+- Project Developer/Project Proponent
+- Validation and Verification Body (VVB)/auditor
+- Credit Buyer (Optional)
+
+### Policy Schemas:
+- Project Developer Application
+- VVB Application
+- Project Listing Application
+- Project Design Document
+- Validation Report 
+- Monitoring Report
+- Verification Report
+- Registry Final Mint
+
+
+### Policy workflow performed through GCR Guardian Middleware API ([API documentation](https://documenter.getpostman.com/view/23057894/2sA3Bj8ZD8)): 
+
+- Project Developer application (PDA) submission by the project developer user role 
+- VVB application (VVBA) submission by the VVB user role
+- Project listing application (PLA) with general information of the project to be submitted by the project developer
+- Project design document (PDD) with details, documentation and design of the project that will be executed by the project developer
+- Project developer to assign appropriate VVB for review of the PDD
+- Validation report submission by the assigned VVB after reviewing the project design document
+- After the validation report has been submitted, Project developer will execute the project on ground as per the design and submit Monitoring Report (MR)
+- Project developer will assign appropriate VVB for review of the MR
+- VVB will review the MR and submit a Verification report to the project developer as well as the standard registry
+- Standard Registry to review the Verification Report and issue appropriate amount of carbon credits to the project developer hedera account
+
+GCR is continously improving the GCR Guardian Middleware API and will continue to provide up-to-date changes and latest versions. 
+
+## A demo of GCR platform to generate Guardian credits 
+
+- Different users will first sign up to the GCR platform and then apply for specific user roles (Project developer/VVB). 
+- Once reviewed and approved by the GCR registry then Project developer can go ahead and create a project profile on the plaform by submitting PLA. They can also add all the documents, images, videos etc. about the project on the project profile
+- Project Developer can also create an organisation on the platform to represent their entity.
+- Once the project is approved and published on the platform, the project developer can submit the Project Design Document and the workflow of the policy as mentioned above will be triggered
+
+Below is a demo video of how a project creation, development and credits minting process takes place on the guardian platform.

+
+---
+Since this demo video we have gone through several rounds of improvements and added functionalities. We will be providing a latest demo of the platform soon.
+
+## Policy Versioning
+
+GCR's policies will continue to evolve and new policies are being developed by us, We will do our best effort to update them within this repository.

+## Introduction
+
+According to a report by [Gold Standard](https://www.goldstandard.org/our-story/sector-community-based-energy-efficiency), 1 in every 9 person on the planet has no access to safe, clean water for them or their families and almost one-third of the world is struggling with access to clean cooking technologies. As a result, most people are still reliant on wood or fossil fuel based cookstoves which will attribute to grave GHG emissions in the future. 
+
+Improved cookstove projects account for 14 percent of projects on the Voluntary Carbon Market (VCM). These projects continue to be demanding due to their benefits, such as reduced deforestation, reduced fuel consumption etc. Safe Water project type is growing exponentially in popularity as they address issues like water scarcity, water pollution, and public health, making them appealing to both environmental and social impact-focused investors.
+
+Gold Standard's Technologies and Practices to Displace Decentralized Thermal Energy Consumption (TPDDTEC v3.1.0)  methodology is applicable to programmes or activities introducing technologies and/or practices that reduce or displace greenhouse gas (GHG) emissions from the thermal energy consumption of households and non-domestic premises. Examples of these technologies include the introduction of improved biomass or fossil fuel cookstoves, ovens, dryers, space and water heaters (solar and otherwise), heat retention cookers, solar cookers, bio-digesters , safe water supply and treatment technologies that displace the boiling of water, thermal insulation in cold climates, etc. Examples of practices include the improved application of such technologies, a shift from non-renewable to renewable fuel (e.g. shift to plant oil fired stoves) , humidity control through improved storage and drying of fuels, etc.
+
+Global Climate Registry (GCR) has built this Guardian Policy that tokenizes the carbon credits after verifying emissions reductions from improved cookstove projects according to Gold standard's TPDDTEC v3.1.0. GCR has digitised the calculation of the Baseline emissions for baseline scenario b in year y, Project emissions for project scenario p in year y, Leakage for project scenario p in year y and Emission reduction for total project activity in year y using formulas defined in the methodology. This Guardian policy, is a reflection of same methodology according to the [Gold standard's typical project lifecycle](https://academy.sustain-cert.com/wp-content/uploads/sites/3/2021/10/GS-Project-Cycle_15042021_Annyta.pdf).

+
+<img width="1232" alt="TPDDTEC guardian policy workflow on GCR platform" src="https://github.com/saharshkhicha18/guardian/assets/71884962/aeb7e479-a5a2-4d1c-9f61-9d64cedd89d5">
+
+## Policy Guide
+
+This policy is published to Hedera network and can either be imported via Github(.policy file) or IPSF timestamp.
+
+Hedera Topic (testnet) - [0.0.4234489](https://explore.lworks.io/testnet/topics/0.0.4234489)
+
+### Available Roles 
+
+  - Project Developer - Project developer who proposes and executes carbon offset project relevent to the methodology and receives credits
+  - Validation & Verification Body(VVB) - Independent third party who audits project's critical documentation and monitoring reports and submits validation and verification reports before issuance of the credits
+  - Global Climate Registry(GCR) - GCR is the trusted registry overseeing the entire project design, development and execution cycle and issuing the credits.
+
+### Important Documents & Schemas 
+
+  1. Project Developer Application (PDA) - Application submitted by the Project Developer Entity with basic information about the developer.
+  2. Validation & Verification Body Application (VVBA) - Application submitted by the VVB Entity with basic information about the VVB.
+  3. Project Listing Application (PLA) - Preliminary design of project highlighting eligibility, additionality and methodology criteria along with stakeholder consultation report
+  4. Project Design Document (PDD) - Submitted after PID is approved, detailed report on project execution, emissions calculations and sustainable development goals.
+  5. Validation Report - Report submitted by the VVB after the review of the PDD submitted by the project developer
+  6. Monitoring Report (MR) - Monitoring report contains analysis on usages on the sample group and estimates carbon avoided/reduced
+  7. Verification Report - Report submitted by the VVB after the review of the MR submitted by the project developer.
+  8. Submit Mint - Requesting specified number of credits into Hedera account of the project developer. This step is done by the registry
+
+### Policy Calculations
+
+Formulas have been incorporated in the methodology in order to calculate baseline emissions, project emissions, leakages and total emission reduction of the project in tons. The calculations are to calculate the estimated emission reductions for Project Design Document and actual emission reductions of the project for Monitoring report. (In order for the calculations to be done automatically, the formulas have been incorporated on Global Climate Registry platform)
+
+  <img width="1583" alt="calculations" src="https://github.com/saharshkhicha18/guardian/assets/71884962/44f44deb-5563-45a1-8ee2-98aa39e569ea">
+
+
+### Carbon credit
+  Carbon credits issued will be a Non-fungible token with 1 NFT equivalent to 1 ton of CO2 offset
+
+  [Example of a minted 1 ton credit NFT](https://explore.lworks.io/testnet/tokens/0.0.4318457/nfts/1)
+
+### Step By Step 
+
+
+#### Project Developer Flow 
+
+1. Select the project developer role and submit the project developer application
+
+    <img width="1583" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/3c5a4291-dcf4-4fda-9f92-e17f25ef5cc3">
+
+    <img width="1559" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/1cf94a20-e813-4148-923f-c207c956f741">
+
+
+2. The project developer can now submit a Project listing Application which is initial details about the project developer entity and the carbon offset project
+
+    <img width="1459" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/bd9b082c-16a8-409a-98a3-fe752245fe02">
+
+    <img width="827" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/f1f96a06-3ab6-44b4-bb44-eac3c8f1b16a">
+
+
+3. Once project is listed, a detailed PDD(project design document) needs to be submitted. This is the most important document highlighting the technical details of project. It includes calculations around baseline, project and leakage scenarios for accurate calculation of avoided emissions. After submitting the PDD, project developer will assign desired VVB for review of this PDD who will then submit a Validation Report in response.
+
+    <img width="1539" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/d32380e4-a40e-41af-b77f-a1b366e689b0">

+    <img width="827" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/fecfff47-331f-41fd-b569-0018ddc0ebc4">
+
+
+4. After VVB has approved the PDD and submitted a Validation Report, project developer will execute the project on ground and submit regular monitoring reports(MR)
+
+    <img width="1573" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/0a4ab0c4-3cb9-4458-a1aa-1b4903a928d8">

+
+
+5. After VVB has approved the PDD and submitted a Validation Report. The credit minting request will be sent to the registry admin. Registry will review the Verification report and choose to mint the amount of credits suggested by the VVB or adjust the amount. Registry admin can also reject the request. Once approved by the registry, minted status will be shown and credits will be issued in the hedera account of the project developer
+
+
+
+#### VVB Flow 
+
+VVB is the external independent third party responsible for reviewing Project Design Documents and Monitoring reports submitted by proponents. They can comment and reject/request changes as well.
+
+1. Select the VVB role and submit the Validator and Verification Body application
+
+   <img width="672" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/1df2d7c5-b464-4d94-b996-6a51f46b2e96">

+
+
+2. Once VVB is created and project developer has assign VVB for PDD review, VVB can review and submit the Validation Report in response if PDD is approved
+
+    <img width="1530" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/d2a3d039-4f94-4e90-8a0f-3068f65d7eca">

+
+
+3. After PDD has been approved and  validation report has been sent by the VVB, project developer will submit monitoring reports and assign to the VVB for review. VVB can review and submit the Verification report in response of MR if approved. Verification Report will be sent to the project developer as well as the registry admin for review
+
+    <img width="1598" alt="image" src="https://github.com/saharshkhicha18/guardian/assets/71884962/03994271-eafd-4174-b2b1-bf2cf5d30f58">

+
+
+#### Registry(Global Climate Registry) Flow 
+
+Registry is allowed to publish and edit policy config, schemas, tokens and all the workflow logic associated with it. They are responsible for approving projects, project proponents, VVBs, and credit issue requests. 
+
+1. Login into the service using registry credentials.
