In Brief

Our corporate governance framework has been in place since the Firm's inception and it is key to accommodating our growing client base and the toughening regulatory environment - it dedicates strong controls for managing client assets and allows for operational control and risk management to be independently reviewed.


Decisions made by investors today will have huge impacts on future wealth. A quote often wrongly ascribed to Albert Einstein is that “compounding in financial markets is the 8th wonder of the world. They who understand it, earn it ... they who do not... pay it.”. We think companies that take early action on greenhouse gas emissions will enjoy a similar benefit. And those that delay, will pay for it. Investors should take note.

undervalued climate action

Climate action today is undervalued

In this piece, we explore the concept of the Time Value of Carbon (TVC): The Time Value of Carbon is the concept that greenhouse gas emissions cut today are worth more than cuts promised in the future, due to the escalating risks associated with the pace and extent of climate action.

We believe this is of fundamental importance for investors, since our work depends on accurately assessing the value that companies can create far into the future, based on the assets and liabilities that they have today. It is also of great importance for the world, since any further delay to climate action will lead to devastating impacts.

The Time Value of Carbon arises from the ruthless maths of climate science. We need to think in terms of carbon stocks, as well as flows, because carbon dioxide (CO2) continues to warm the planet for many decades after it is released. Globally, we emitted around 40 billion tonnes of CO2 in 2020 despite the economic impact of the pandemic.1 At this rate, we will exceed the carbon budget for 1.5 degrees of warming by 2030.

Differences across climate models mean that the carbon budget lies in a range, but on one recent estimate it is just 230 GtCO2 for a 66% chance of keeping to 1.5 degrees warming above pre-industrial levels in 2100, or 440 GtCO2 for a 50% chance.2

Uncertainty gives us further reasons to act now. 1.5 degrees has become the benchmark for climate action, in part because scientists believe a temperature rise beyond this level would increase the risk associated with long-lasting or irreversible changes. Potential tipping points in the climate system include disintegration of polar ice sheets, shifting monsoon rains and dieback of the Amazon rainforest – which would in turn release enormous volumes of carbon into the atmosphere.3

Against this backdrop, it clearly makes sense to cut emissions today, rather than in ten years’ time. A company that stops emitting CO2 this year creates a benefit for the climate system each year into the future. Companies that start to cut in 2030 will have spent another ten years drawing from the global carbon budget, and by then the 1.5 degree goal could be out of reach. This is why long-dated climate goals with no short term action are unacceptable. It is also why we believe that near term action creates considerable value.
