The Science of Climate Change

Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.

Tackling the Plastic Crisis

Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge

The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.

Case Study: How to Make Municipal Waste Investable

8 mins 33 secs

Key learning objectives:

  • Outline steps to make waste systems investable

  • Identify the four components of a blended finance model

  • Outline strategies to align stakeholder needs

  • Understand key lessons for other pre-investable systems

Overview:

Transforming municipal waste into an investable system requires reliable revenue, strong operating models, and stakeholder alignment. Many essential services are “pre-investable” due to high risk and low returns. A blended finance approach combining philanthropic, concessional, and commercial capital reduces risk and enables scaling. Key strategies include treating waste like a utility, creating ring-fenced legal entities, and using revolving credit facilities to manage repayment risks. Lessons from Indonesia’s municipal waste model show how these principles can make pilots scalable and investable, offering insights applicable to other sectors like health, education, and environmental services.

Summary
How can municipal waste systems be transformed into investable assets?
Municipal waste, often treated as an underfunded social service, can be made financially viable by professionalising revenue collection, treating it like a utility, and supplementing user fees with additional funding sources like plastic credits or national taxes. These steps create predictable revenue streams, reduce commercial risk, and lay the foundation for scalable investment.

What are the key components of a blended finance model for waste systems?
  1. Treating waste as a utility to generate steady revenue
  2. Creating a ring-fenced legal entity for transparency and accountability
  3. Blending philanthropic, concessional, and commercial capital to de-risk investment and scale the system
  4. Establishing a revolving credit facility to cover early-stage repayment gaps and protect investors

How can the needs of governments, investors, philanthropies, and operators be aligned?
Alignment requires understanding each stakeholder’s priorities: local governments need stable revenue and predictable costs, investors require clear repayment paths, philanthropies aim to leverage impact, and operators need capital with defined responsibilities. Blended finance structures, clear legal entities, and revenue models designed to minimise risk help meet these diverse needs, building confidence and enabling investment at scale.

How can lessons from municipal waste finance be applied to other pre-investable sectors?
The principles of strong operating models, predictable revenue, stakeholder alignment, and blended finance can be adapted to sectors like health, education, or environmental services. By designing credible financial structures and reducing perceived risk, even sectors with weak economics or volatile revenues can become investable, enabling national-scale transformation.
