Second Party Opinions & Transaction Evaluations

S&P Global has acquired the Shades of Green business from CICERO

What are Second Party Opinions?

S&P Global Ratings provides a variety of Second Party Opinions (SPOs), which are independent assessments of a company’s financing or framework's alignment with market standards and typically provided before any borrowing is raised. Our options include Use-of-Proceeds SPOs (Green, Social, Sustainability) and Sustainability-Linked SPOs.

In December 2022 S&P Global acquired the Shades of Green business from CICERO, further expanding the breadth and depth of our SPO offering. Shades of Green have been championing SPOs in the global green financing market since 2008 after publishing the very first SPO on the World Bank’s Green bond framework and remain the largest external reviewer by volume globally. At the heart of all their SPOs is the multi-award-winning Shades of Green methodology, which assigns shadings to investments and activities to reflect the extent to which they contribute to the transition to a low carbon and climate resilient future.

With S&P Global Ratings' global experience in assessing sustainable finance risk, coupled with Shades of Green’s deep expertise in climate and sustainability, we are ready to help you navigate access to the public and private sustainable debt markets with solutions that deliver the rigor and transparency your investors and lenders demand.

Second Party Opinions
Second Party Opinion - Use of Proceeds Financing

We offer three types of Use of Proceeds SPOs:

  • Social SPOs 
  • Sustainability SPOs


Second Party Opinion - Sustainability-Linked Financing

Assesses a sustainable finance framework or transaction - where the proceeds will be used for general corporate purposes but incorporate measurable, forward-looking key performance indicators which are linked to sustainability objectives targets into the financial and/or structural characteristics of the instrument - for alignment with: ICMA’s Sustainability-Linked Bond Principles, LMA’s Sustainability-Linked Loan Principles. 

What do Second Party Opinions on use-of-proceeds financings include?
Types of Use-of-Proceeds Financings 
We offer three types of Use-of-Proceeds Second Party Opinions (SPOs): 



Green SPO: Alignment with Green Bond Principles (GBPs), ASEAN Green Bond Standards (AGBS) and/or Green Loan Principles (GLPs), EU Taxonomy. 
 
Our green SPO assessment is based on the well-established, award-winning Shades of Green methodology, which gives transparent information on how well a green bond/loan aligns with a low-carbon climate resilient future. The Shades of Green (Light/Medium/Dark Green) reflect the extent to which investments and operations contribute to the transition to a low carbon and climate resilient future and their exposure to climate risk.

Social SPO:
Assesses a framework or transaction - where the proceeds will be used exclusively to finance eligible social projects - for alignment with third-party principles, including Social Bond Principles (SBPs) and/or Social Loan Principles (SLPs). 


Sustainability SPO: Assesses a framework or transaction - where the proceeds will be used exclusively to finance eligible environmental or social projects - for alignment with third-party principles, standards and taxonomies, including GBPs/SBPs, Sustainability Bond Guidelines, EU Taxonomy.  


Mapping to the UN Sustainable Development Goals 

For all analytical components we can determine whether they are aligned, or not aligned, with the relevant Principles. In addition, when the Principles make further recommendations for best practices on disclosures and commitments in documentation, or there is an emerging best practice, we can provide an additional opinion on an entity's commitment as satisfactory, strong, or advanced. 



Analysis of EU Taxonomy Alignment (Upon Issuer Request) 

We offer an “Analysis of EU Taxonomy Alignment” as an appendix to an SPO or Transaction Evaluation. We can opine on whether a financing document aligns with the EU Taxonomy in cases when at least one economic activity is covered by Technical Screening Criteria (TSC), which are incorporated into European law via delegated acts. This analysis aims to help readers see how activities that will be funded with proceeds from a financing framework, or a specific transaction, align with the EU Taxonomy. 



For more detail on how we assess EU Taxonomy alignment, please refer to our published Analytical Approach.

What is a Transaction Evaluation?

A Transaction Evaluation provides a point in time score on the relative environmental benefit generated by a green/resilience financing and an opinion on governance and reporting. Green Transaction Evaluation is similar to a pre-issuance impact assessment and is often combined with an Alignment Opinion with: ICMA's Green Bond Principles, ASEAN Green Bond Standards, and LMA/APLMA/LSTA's Green Loan Principles. 

Key Components of Transaction Evaluations

A point-in-time relative impact
score at the transaction level.

Scores projects that are either in a
pre-or post-issuance stage.

Considers a variety of environmental key
performance indicators.

Not limited to issuer self-labelled green bonds.

Governance & Reporting Opinion: Weak,
Satisfactory, Strong, Advanced.

Green Transaction Evaluation can also provide alignment opinion to third-party market standards.

Benefits of a Transaction Evaluation for Companies

Clearly articulate the net environmental benefit of a transaction.

Increase transparency with additional analysis and rationale of key strengths and weaknesses.

Help investors easily compare and benchmark against other sustainable financings.

Differentiate your company from its peers by going beyond the standard external review.



  • Markus Stachel Group Head Investor Relations, DZ Bank
    The Green Evaluation process was very transparent and characterized by mutual understanding of the relevant topics. We had full confidence in S&P’s ability to assess the green assets which formed part of the transaction. The Green Evaluation helped us to successfully place the bond with a wide variety of investors.
