Bondholder engagement toolkit

Bondholders control a critical share of global capital. This toolkit shows how to direct that influence. 

We set out practical tools that turn lending relationships into real leverage on transition risk – scored so you can see which levers to pull first.

Navigate below to find multiple ways in which you can engage with issuers, directly or indirectly, and download the in-depth analysis which assesses the relative practicality of each tool based on our team's experience as market practitioners.

Benefits of bondholder engagement

Better engagement offers key advantages to investors seeking to manage climate and nature risk. 

Investors can:

  • Influence all borrowers, not just listed equity issuers.

  • Link lending terms with credible performance targets.

  • Amplify existing stewardship, rather than duplicating it.

The bondholder engagement toolkit identifies concrete ways investors can exercise their influence, based on AFII’s experience as market practitioners. 

On this page, you can find a short description of each tool, with case studies and practical examples of engagement opportunities across sovereign and corporate issuers.

You can download the assessment by AFII's expert team, which scores the engagement tools by their potential influence and feasibility. There is also a summary available for easy reference and sharing with colleagues.

Explore the tools

The toolkit brings together 11 practical routes through which bondholders can strengthen engagement on climate and nature. The tools vary in feasibility, influence and timing, so users can explore those most relevant to their own mandates, holdings and engagement objectives first.

This is a contractual right, detailed in English law bond prospectuses, which is rarely used.

While there is no legal obligation on the issuer as to the outcomes of the meeting, it does offer a formal platform to escalate engagement objectives.

There can be hurdles to identifying sufficient bondholders to reach the threshold and some procedural hurdles, but it offers effective direct communication on concerns.

Indices shape capital flows. Passive funds directly invest only in eligible instruments, and active funds target outperformance, and so are driven by benchmark inclusion.

Index use is deeply embedded in market practice, and has the potential to reinforce transition accountability.

Index providers are motivated to create indices that investors want, so there is leverage in this relationship.

This combines legitimacy (as is linked to the issuer's needs for funds), power (threat of funds being withheld, or additional terms for those funds), and urgency.

Once refinancing is secured, investor influence is reduced.

AFII's Bond Horizon helps predict issuance to support this tool.

Public expectations from asset owners, leading to high profile manager changes, are often not represented in formal written mandates which prioritise financial return.

Asset owners can hold significant power to influence terms with their managers.

Mandates are subject to periodic review, allowing engagement requirements to be reviewed.

An extension of Sustainability-Linked Bond developments where bond economic terms are linked to performance against KPIs.

Formalises an investor divestment option based on KPIs.

May require pricing concession to be acceptable.

Collective engagement is a well-established strategy in equity markets, where groups of investors work together to add influence to their issuer discussions.

Several investor networks have fixed income specific work streams to support these interventions.

Such collaboration saves time, as work can be shared between investors.

Investors often hold several products with the same issuer.

When engagement objectives are fully aligned, using routes via all invested products can increase influence.

Requires internal coordination within investors.

There are opportunities for issuers to raise the profile of climate and nature related disclosure and strategy in their investor dialogue.

Where this is encouraged by investors, the quality of issuer-investor understanding increases.

If a pricing reaction in bond spreads were observed, this could further incentivise.

MAR concerns are often cited for lack of collaboration in fixed income markets, despite such coordination being more common in equity markets.

Regulatory clarity could allay concerns.

Many fixed income investments are held via custodians or in managed accounts, and with limited exceptions legal and beneficial ownership will not be disclosed.

If investors can make strategic disclosure of collective holdings, that signals the weight behind their engagement objectives, and supports collaboration.

This could also be incorporated in asset owner mandates.

This proposes tighter covenants which are traditionally used in high-yield debt markets.

Issuer reluctance restricts the feasibility, but may improve if the borrowing landscape for high-emissions issuers deteriorates.

Can be tailored to specific climate- or nature-related objectives.

This section highlights how the tools can be applied in practice, featuring issuers from typical bond portfolios. Each case illustrates when and how investors can use their position as lenders to shape strategy, disclosure, and transition‑aligned terms.
