GreenArc BioEnergyIndex

Impact + Rural Economy

Climate infrastructure with outcomes beyond energy.

We are building toward plant-level Impact Ledgers. No GreenArc plant is operating yet. These are intended outcomes and a reporting design, not measured results.

Explore the rural economy

Intended outcomes

Outcomes beyond energy.

Clean Energy

Renewable CBG intended to displace fossil gas.

Climate

Potential avoided burning, methane reduction and additional carbon interventions.

Rural Prosperity

Residue income, crop diversification, logistics, employment and potential climate-linked revenue.

Circular Agriculture

Designed to return nutrients and organic matter to agriculture.

Water & Resource Productivity

Locally validated practices and crop choices that may reduce resource intensity.

Separate boundaries

Different outcomes. Separate accounts.

Separate impact ledger scopes Direct outputs, avoided emissions, agricultural interventions and removals are separate accounts. Metered outputs do not automatically establish avoided emissions, field changes or durable storage. Direct outputsAvoided emissionsAgriculturalinterventionsRemovals Measured at the meterStated counterfactualVerified on the fieldDurable, measured storage
Separate scopes, with no automatic transfer of impact between them.

Direct outputs

CBG, fermented organic manure (FOM), biogenic CO₂

What counts
Measured, metered quantities.
What does not count
Nameplate capacity and projections.
Double-counting rule
An output is reported once, at the meter.

Avoided emissions

Fossil-gas displacement and avoided open burning

What counts
Displacement against a stated counterfactual; only residue that would otherwise have been burned counts as additional diversion.
What does not count
All plant intake by default.
Double-counting rule
Avoided emissions are never added to removals.

Agricultural interventions

Alternate wetting and drying (AWD), FOM use on fields

What counts
Field-verified practice change with farm-level evidence.
What does not count
FOM produced or sold.
Double-counting rule
A tonne of FOM is not a tonne of displaced fertiliser.

Removals

Biochar in mineral soils, enhanced rock weathering (ERW), CO₂ storage

What counts
Only durable, measured storage.
What does not count
In-process use.
Double-counting rule
A separate ledger line; carbon rights and overlap checked before any claim.

Removal pathways remain Evaluating or Research. No removal is claimed.

Measurement before claims

Count the whole boundary.

  • We will define the boundary and state the counterfactual for each impact claim.
  • We will count our own emissions, including methane slip, trucking and power.
  • Activity records such as weighbridge slips are not by themselves proof of origin or impact.
  • We will check ownership and overlap before claiming any carbon attribute.
  • We intend to seek third-party assurance of reported outcomes.
Peer-reviewed research finds that methane leakage during digestion and biogas handling can largely erode the climate benefit of biogas systems. Net accounting therefore has to count methane losses. Basis
External context Sourced

The study covers wastewater biogas facilities, not agricultural-residue CBG; it supports a general accounting principle only.

Making or selling digestate-based manure is not the same as displacing mineral fertiliser. Research finds digestate nitrogen is less available to crops than mineral nitrogen, and highly variable. Basis
External context Sourced
A global meta-analysis put digestate's average nitrogen fertiliser replacement value at about 0.78 of mineral fertiliser, with very wide variation between experiments. Basis
External context Sourced

Digestate in general, not paddy-straw FOM or Indian soils. This is not a GreenArc fertiliser-displacement figure.

Rural Economy

New income can flow to farmers and local businesses.

These potential income channels are designed to create opportunities around the plant and its agricultural network. We do not present them as payments already made.

Residue supply

Potential

Residue markets are designed to create income from agricultural resources.

Who may benefit: Participating residue suppliers; report landowner, tenant and aggregator receipts separately.

Appropriate energy crops

Potential

Suitable crop choices are designed to create opportunities for dependable biomass demand, subject to food, water, biodiversity and land-use safeguards.

Who may benefit: Participating growers and tenants; report production costs alongside receipts.

Local logistics

Potential

Collection, aggregation and transport are designed to create rural enterprise opportunities.

Who may benefit: Aggregators, transporters and their workers; distinguish business receipts from wages.

FOM and input savings

Potential

Nutrient return is designed to create opportunities for agricultural input savings, subject to field evidence.

Who may benefit: Farmers applying FOM; any savings depend on actual use and demonstrated fertiliser displacement.

AWD and potential carbon participation

Potential

Climate programmes are designed to create possible additional participation channels where practices, measurement and rights are validated.

Who may benefit: Participating farmers and tenants, subject to consent, programme terms and carbon-rights checks.

Jobs and skills

Potential

Plant development and agricultural services are designed to create opportunities for work and skills.

Who may benefit: Workers; report direct, seasonal, logistics and induced jobs separately.

We will publish a rural economic multiplier only once it is measured; we do not estimate one today.

Core plant economics should be designed around energy and agricultural outputs. Carbon revenue is potential upside, not a substitute for viable project economics.

External context

Policy is context, not a plant entitlement.

GOBARdhan is a national scheme approved by the Union Cabinet and run by the Ministry of Petroleum and Natural Gas. It builds on the earlier SATAT, pipeline-connectivity, biomass-aggregation, manure-assistance and central-assistance schemes and brings them onto one platform across the CBG value chain. Basis
External context Sourced
The notified CBG Blending Obligation applies to the CNG (transport) and PNG (domestic) segments of city gas distribution and steps up in three annual stages: 3%, then 4%, then 5% onwards. Basis
External context Sourced
When it announced the obligation, the Government said it is estimated to facilitate around 750 CBG projects. Basis
External context Sourced
CBG plants obtain a registration number through the national GOBARdhan Unified Registration Portal, which the Ministry of Petroleum and Natural Gas requires before its support can be availed. Basis
External context Sourced
CBG and biogas plants are registered on the Department of Fertilizers' Integrated Fertilizer Management System portal under the organic-manure support framework. Basis
External context Sourced
Haryana's renewable energy agency has published a draft state CBG policy for stakeholder comment. We found no final notification in our latest check. Basis
External context Sourced

The obligation is not a plant-level offtake guarantee. Registration is an entry step, not commissioning or benefit approval; this page makes no claim about GreenArc’s registration status. Portal registration says nothing about FOM quality, sales or current incentive eligibility. Draft policy provisions are not displayed.
