Sustainable Finance
The green and sustainability-linked debt market exceeded $1.1 trillion in 2025. SYNE Sustainable Finance gives you the infrastructure to access it — manage green bond issuance, structure sustainability-linked loans, optimise your debt portfolio for ESG-adjusted cost of capital, and generate the verified data that investors and rating agencies require. And when you're ready to move beyond debt instruments into digital climate securities, SYNE Markets — our full-stack digital market infrastructure — transforms your verified climate and nature outcomes into collateral-ready assets, rated instruments and tradeable digital climate securities.
From your first green bond framework to sustainability-linked revolving credit facilities, SFDR-aligned portfolio management and the next generation of digital climate securities — SYNE gives you the verified data and workflow infrastructure that every sustainable finance instrument requires.
The global labelled bond market surpassed $1.1 trillion in 2025, with green bonds the dominant instrument. SYNE manages the complete bond lifecycle — from initial framework design and eligible project screening through to ongoing use-of-proceeds allocation tracking, annual impact reporting and external review coordination. SYNE also supports the EU Green Bond Standard (EU GBS) under the European Green Bond Regulation — providing the EU Taxonomy technical screening criteria assessment, DNSH verification and No Significant Harm documentation required for EU GBS label bonds. All underlying ESG data used in bond reporting is the same verified data powering your CSRD disclosure, giving you a single auditable evidence source.
Sustainability-linked instruments differ fundamentally from use-of-proceeds bonds — the interest rate or coupon is directly tied to the borrower's performance against pre-agreed ESG KPIs and Sustainability Performance Targets (SPTs). If you hit your targets, your margin steps down. If you miss them, it steps up. SYNE manages the full SLL and SLB lifecycle: KPI selection aligned to ICMA's SLB Principles and LMA's SLL Principles, SPT calibration against science-based pathways and sector benchmarks, ongoing KPI tracking and lender reporting, and automatic margin ratchet calculations — so your treasury team always knows where you stand before the bank asks.
ESG performance is no longer just a reputational issue — it has a direct, measurable impact on your cost of capital. Multiple academic studies and Moody's, S&P and Fitch analyses confirm that companies improving their ESG ratings see 25–45 basis point improvements in credit spreads per rating grade. SYNE's debt portfolio module models your current and projected WACC under different ESG performance scenarios, tracks credit rating migration risk, optimises the structure of your debt book for maximum ESG-related cost savings and identifies which ESG improvements deliver the best capital cost benefit per effort invested.
For financial institutions — banks, asset managers, insurers and pension funds — EU SFDR and EU Taxonomy compliance has become the dominant regulatory requirement. SYNE's SFDR module handles Principal Adverse Impact (PAI) indicator calculation for all 18 mandatory and additional PAIs, SFDR Article 6/8/9 product classification with supporting evidence, EU Taxonomy substantial contribution assessments for lending and investment portfolios, and the ongoing monitoring of portfolio-level taxonomy alignment percentages required for SFDR disclosures. For non-financial corporates, SYNE provides the taxonomy eligibility and alignment calculations required under CSRD ESRS E1 and the EU Taxonomy Regulation.
Supply chain finance — reverse factoring, dynamic discounting and approved payables finance — becomes a powerful ESG lever when the financing rate is linked to the supplier's sustainability performance. SYNE's supply chain finance module connects supplier ESG scores (from the Supplier Management module) directly to financing rates — offering suppliers who achieve strong sustainability performance access to earlier, cheaper working capital, and using the financial incentive to drive genuine Scope 3 ESG improvement at scale across your supplier base. This is green supply chain finance that produces real behaviour change, not just preferential credit for already-compliant suppliers.
