Challenge

Where things stood before SYNE was engaged.

A mid-sized city preparing its first municipal green bond, largely to fund public transit electrification, wanted an independent sustainability rating that dedicated ESG fixed-income funds would recognise, having heard from its underwriter that unrated municipal green bonds were seeing thinner demand from that specific investor base.

The city's sustainability office had solid programme-level data on the transit project itself but had never had the municipality's broader sustainability governance and reporting practices independently assessed.

Approach

What SYNE actually did.

SYNE rated the municipality under the Sustainability Ratings for Governments methodology, assessing both the specific transit electrification programme's environmental impact and the city's broader sustainability governance and public reporting practices.

The rating report was structured specifically for a fixed-income audience, with a dedicated summary section mapping the city's practices against the criteria dedicated ESG fixed-income funds most commonly screen for.

Outcome

Where things stand now.

The city received an AA Sustainability Rating, published ahead of the bond's roadshow and referenced directly in investor materials. Several dedicated ESG fixed-income funds that had not previously participated in the city's conventional issuances took allocations in this deal.

The bond priced inside initial guidance, with the underwriter attributing part of the additional demand directly to the independent rating giving ESG-mandated investors the screening evidence they needed to participate.
