Our Philosophy

Our world is facing a global environmental crisis, one with such magnitude that it will affect each and every one of us. We believe that green bonds have a vital role to play in mitigating the severity of the global environmental crisis by supporting positive climate change solutions. Our aim is to address climate change by focusing on net zero and energy transition as well as promoting nature conservation, protecting ecosystems, and preventing biodiversity loss. By balancing fundamental and quantitative analysis, we provide a more comprehensive and sophisticated approach to investing in green bonds, ensuring that portfolios are both sustainable and profitable. This approach results in the strategy having the following key features:

Sustainability focussed themes

Our commitment to sustainability is the driving force behind our investment strategy. In line with this, our portfolio prioritises three key areas when considering a bond to include in our investment portfolio:

Focus on issuers who have set ambitious net zero aspirations and have clear plans to implement them. We believe that investing in companies that are proactively working towards reducing their carbon footprint is crucial in the fight against climate change.

Seek out sectors that are supportive of the transition to a net zero economy. These include areas such as renewable energy, sustainable transportation, and green building materials. By investing in these sectors, we aim to accelerate the transition towards a more sustainable future.

Prioritise bond issuances that promote nature and the protection of ecosystems. We recognise the importance of preserving our natural environment and believe that investing in projects that protect and restore our ecosystems is essential to achieving a sustainable future. Overall, our portfolio aims to promote sustainability-oriented goals by investing in bonds that align with our values and contribute to a more sustainable future for all.

Proprietary bottom-up sustainability assessment

Our unique bottom-up review process applies to every holding in the portfolio. This distinctive approach combines sustainable assessments from three different lenses:

  1. The issuer’s sustainability strategy
  2. The pre-issuance bond framework
  3. The post-issuance allocation and impact report

Through this process, we gather and review both third-party data and source materials to ensure consistency between the issuer’s sustainability strategy and the issuance of a labelled bond but also that the bond itself follows best disclosure standards with transparent and impactful use of proceeds. This qualitative review process is taking place before investing and, if concerns are identified, can lead to the decision not to invest or to conduct enhanced due diligence, through engagement.

Investment process

Our investment process is designed to integrate sustainability considerations into our investment decisions whilst integrating top-down and bottom-up approaches, leveraging both quantitative analysis and qualitative team input to construct a well-diversified and sustainable green bond portfolio. This is done in conjunction with ensuring that we invest in bonds that align with our commitment to sustainable development and contribute to positive environmental and social outcomes.
