Expertise that delivers
Sustainable Finance for Financial Institutions
We strengthen sustainable finance capabilities within financial institutions to scale structured
sustainability investments. This work:
- Enables commercial banks and investment managers to unlock concessional and blended
finance, meeting international standards and fulfilling impact reporting requirements; - Builds the strategies, skills, tools, and policies needed to originate, structure, and manage
climate finance transactions; and - Supports financial product innovation that mobilises private capital for a just energy
transition
Sustainable Debt and Guarantees
A just energy transition requires large volumes of patient capital. We support the
design and implementation of innovative sustainable debt instruments and risk
transfer mechanisms that enable capital mobilisation at scale through rebalancing
risk-return across the capital stack. We do this by:
- Identifying sustainable finance debt and credit enhancement instruments
aligned to market capital needs - Assessing potential for securing preferential terms through monetisation of
impact - Engaging with target funders to align on key sustainability terms (use of
proceeds and reporting) - Developing sustainable finance frameworks and documentation aligned to
international market standards including ICMA Principles, Climate Bond
Standard, EU and Multilateral Development Bank Taxonomies and IFRS
Carbon Finance
We design integrated carbon market investment strategies and solutions to unlock Africa’s vast
carbon potential. Our services include:
- Carbon market data and regulatory insights provision
- Carbon investment vehicle design and capital structuring
- Carbon project pipeline due diligence and transaction support
Impact finance
We design impact strategies and structures that mobilise capital for measurable social and
environmental outcomes. We do this by:
- Creating blended financed structures that mobilise patient, risk-tolerant capital for projects
with longer horizons or higher upfront uncertainty;
- Identifying target investors and performing market sounding to ensure robust design; and
- Embedding rigorous impact measurement to ensure transparency and accountability in
delivering social and climate benefits
Green Growth Strategy
We develop green growth strategies that position organisations to capture emerging opportunities in
markets for clean technology and nature-climate solutions. We support this through:
- Identifying emerging commercial opportunities and evaluating regulatory barriers to secure
first-mover advantage; - Improving access to preferential capital through credible transition plans that attract
sustainability-linked financing; - Aligning corporate strategy with national transition priorities to strengthen policy influence
and market positioning; and - Supporting innovative business models that expand clean energy access and strengthen
local participation
