-
Barriers and Blockers in Scaling Sustainable Finance
-
Short-Term Barriers
-
Political/geopolitical headwinds, backpedalling, and "green hushing."
-
Lack of all parts of the value chain working together—missing links in policy, market infrastructure, viable financial solutions, and scaling successful pilots.
- Quote:
"We have pockets of excellence...but what we don't see is...weaving together all those factors so that we focus on sectoral transitions...that can be replicated and scaled out." (10:03)
- Quote:
-
-
Need for ‘Glue’
- A holistic approach to connect all players and initiatives around common real economy outcomes.
Opportunities and Sectoral Innovation
-
“Every Sector Matters”
-
While every sector is critical, Emma highlights the emerging opportunity in "nature, biodiversity, agriculture" finance, which historically lacked clear revenue streams and thus struggled to attract investment.
- Quote:
"We've seen a 12% potential reduction in UK GDP from nature degradation... larger impact than COVID… The quantification of risks to our supply chains is huge." (13:27)
- Quote:
-
-
Innovative Market Models
- GFI leads the “Revenues for Nature” project, exploring investable and scalable business models for natural capital and biodiversity.
Role of Finance Professionals: The Three Rs
-
Risk, Reputation, Return
-
Professionals must balance the risks of climate impacts, the reputational implications of sustainability inaction, and the creation of viable returns.
- Quote:
"Our mantra was risk, reputation and return... You have a lower risk asset, which means it's lower likelihood of default, which means you could offer a lower interest rate without eroding your margin." (15:21–18:00)
- Quote:
-
-
Case in Point: Green Mortgages
- Lower default rates on energy-efficient homes justify preferential green mortgage terms without reducing lender margins.
Public Policy and Regulations
-
Essential Role of Policy
-
Reliable, clear policy frameworks and demand signals are crucial to scaling green finance and giving investors confidence.
-
Public sector can use "blended finance," providing small amounts of catalytic capital to support new markets and de-risk investments.
- Quote:
"We cannot scale green finance in a vacuum. We need to have enabling policies and regulations and demand signals that will let the investment community know that actually this is a good sector to invest in." (19:39)
- Quote:
-
-
GFI’s Policy Leadership
- Advises on deployment of the UK National Wealth Fund (£27+ billion) to maximize private capital crowd-in and catalyze priority sectors.
Optimism, Impact & Future Outlook
-
Despite Headwinds, Deals Are Happening
-
Emma cites recent high-profile deals and blended finance platforms, emphasizing that meaningful capital is still being deployed even if not always under the "green" label.
- Quote:
"We're seeing deals happen, they're not always labeled green, but they're still having a positive climate impact." (22:48)
- Quote:
-
-
Shift to a ‘Transactional Phase’
- The sustainable finance sector is maturing, focusing on real-world investments and practical outcomes.
