Readiness support and training for public administrations preparing for their first rating.

SYNE Government Ratings Framework

80 weighted criteria. Four dimensions. One score.

Every Government Sustainability Rating is built from 80 individually weighted criteria spread across Environmental Performance & Resilience, Social Development & Equity, Governance & Institutional Quality, and Fiscal & Debt Sustainability - the same weighted-average approach used across every SYNE Rating, adapted for the public sector.

A transparent, explainable scale

Six tiers, from exemplary to distressed.

The SYNE Government Rating scale runs from AAA to D - the same scale used across every SYNE rating - so a municipality, a state, and a sovereign can all be read on the same terms.

AAA
ExemplaryScore 90–100

Front Runner · Strong performance and verified data across all four dimensions, with resilient institutions and fiscal capacity.

Minimal risk - benchmark-setting governance and sustainability performance.
AA
AdvancedScore 75–89

Strong across most dimensions, with only minor gaps in fiscal buffers or institutional capacity.

Low risk - stable outlook.
A
DevelopingScore 60–74

Material gaps identified in one or more dimensions, with a credible pathway to close them.

Medium risk - improvement trajectory expected.
B
EmergingScore 45–59

Significant improvement needed, particularly in fiscal sustainability or institutional quality.

High risk - elevated fiscal or governance exposure.
C
DeficientScore 20–44

Fundamental gaps across multiple dimensions, with limited near-term capacity to close them.

Very high risk - material fiscal or institutional fragility.
D
DistressedScore below 20

No material evidence of sustainable fiscal, environmental or institutional performance.

Distressed - significant structural reform required.

Comparable across levels of government

A municipal AA and a sovereign AA mean the same thing on the underlying scale, even though the specific criteria weightings differ by government type.

Trajectory matters as much as points

SYNE reports whether a government is improving, stable, or declining relative to its previous rating - informative across multi-year budget and election cycles.

Every rating includes a pathway

Governments rated below AA receive a prioritised improvement pathway, developed jointly with SYNE's public sector advisory team where requested.

Who uses Government Sustainability Ratings

Built for anyone with a stake in how a public institution performs.

A government rating is a shared reference point - the same score means the same thing whether you're buying a sovereign bond or evaluating a city's resilience plan.

Sovereign & Municipal Bond Investors

Screen and benchmark government debt issuers on a comparable, independently verified sustainability signal.

Multilateral Development Banks

Inform lending and guarantee decisions with a consistent, comparable rating across borrower governments.

National & Local Governments

Benchmark performance against peer jurisdictions and identify priorities for reform or investment.

Rating-Linked Lending Programmes

Tie financing terms to demonstrated sustainability performance using an independent, published rating.

Citizens & Civil Society

Access an independent, plain-language view of how a government is performing against its own commitments.

Credit Rating Agencies

Reference an independent sustainability overlay alongside traditional sovereign and municipal credit analysis.

Why Government Sustainability Ratings matter

Sovereign ESG data is still fragmented, inconsistent, and hard to compare.

Unlike corporate ESG reporting, government sustainability data is scattered across ministries, statistical agencies, and multilateral databases, published on different cycles and in different formats. Investors and lenders assessing sovereign or municipal risk are often left assembling a picture themselves, with no consistent scale to compare one jurisdiction against another.

Fragmentation

Why sovereign ESG data is hard to use

Data scattered across ministries and multilateral sources, on inconsistent cycles, makes cross-jurisdiction comparison difficult without independent normalisation.

Comparability

What it means for bond investors

A consistent rating scale lets an investor compare a municipal bond in one country against a sovereign bond in another on the same terms.

Access to finance

What it means for governments

A strong, independently verified rating can support access to sustainability-linked sovereign and municipal financing.

The signal

What a government rating actually tells you

A weighted judgement of environmental, social, governance and fiscal performance - built on public, verifiable data, not internal government reporting alone.

Methodology

What separates a SYNE government rating from a sovereign credit score.

Four principles run through every rating, from a small municipality to a G20 sovereign.

Standard

Aligned with international frameworks

Grounded in the UN SDGs, sovereign ESG frameworks, and internationally recognised public governance indicators.

Sourcing

Built on public, verifiable data

Ratings draw on public statistical, budgetary and institutional data - cross-checked rather than accepted at face value.

Independence

Regulatory-grade independence

No commercial lending relationship between SYNE and a rated government influences the outcome.

Consistency

Comparable via the SYNE Index

Every government rating maps onto the same SYNE Index quadrants used across corporate, carbon and supplier ratings.

Government rating vs. a corporate rating

Same methodology family, a different subject.

A Government Sustainability Rating shares its underlying approach with SYNE's corporate ratings, but the criteria, data sources and independence considerations differ.

The distinction

Public institutions, not companies

Criteria are built for public administration - fiscal policy, institutional quality and equity - rather than corporate governance and disclosure.

Data sourcing

Public records, not corporate disclosure

Ratings draw on public statistical, budgetary and institutional data rather than a company's self-reported filings.

Independence

No lending relationship influence

SYNE's government ratings are structurally separate from any lending or guarantee decision that might reference them.

Timeline

10–16 weeks, start to publication

Government ratings typically run longer than corporate engagements, reflecting the breadth of public data involved.

Disclosure

Usually published

Unlike many corporate ratings, government ratings are more often published by default to support public accountability.

Recognition

Referenced by lenders & bond markets

Used by multilateral lenders and sovereign/municipal bond investors across our 71 licensed markets.
