Exclusive Interview: Pekka Piirainen, ET Index Research



Pekka Piirainen is responsible for investor engagement at ET Index Research, a low-carbon investment solutions provider dedicated to helping investors understand, manage and reduce carbon risk.

Pekka is a climate and sustainability expert, having worked on both private and public climate change engagement. Pekka has a broad range of experience in both the renewables sector and international climate negotiations, working on wind energy deployment at RenewableUK and representing UK youth as a delegate at COP21 as a part of the UK Youth Climate Coalition (UKYCC). He is also actively involved in the Fossil Free divestment movement, calling on institutions to end their investments in fossil fuels.

Before joining ET Index, Pekka headed the Environmental Investment Organisation’s Project 1% climate campaign and completed his military service in the Finnish Defence Forces. He holds a degree in History from UCL.

What is ET Index Research?

ET Index Research is working to accelerate the low-carbon economic transition, redirecting capital from high-carbon to low-carbon companies. We are a low-carbon investment solutions provider helping our clients identify, understand and manage carbon risk. We help investors reduce the risks associated with climate change in their investments, while allowing them to make the most of the opportunities arising from the clean energy transition that is already well underway.

Our services range from portfolio carbon footprinting and extensive analytics to a series of low carbon and fossil free index products that include supply-chain emissions. Our aim is to revolutionise the way investments are made in a carbon-constrained world. All ET Low Carbon Index products are linked to a transparent and public ranking of the world’s largest 2,000 companies. For corporates in the rankings, the only means of moving up the index and increasing capital allocation is by continuously lowering emissions. In other words, if enough money were to flow through our indexes, the change in demand would tie a company’s share price to its carbon efficiency.

What was the driver behind this?

The world is warming at an unprecedented rate, threatening the continued existence of global civilisation. Not only are temperatures and oceans rising, with stronger hurricanes, deeper droughts and a plethora of other physical risks, climate change is changing the geopolitical fabric of the planet. Increasing evidence is linking the conflict in Syria to changes in climatic conditions in Northern Africa – what happens when changing rainfall patterns cause crops to wither globally and hundreds of millions fall into poverty and starvation? Already we are seeing a multitude of refugee crises, a rising tide of populism and xenophobia, and the rise of a new wave of demagogues.

Yet at the same time, the world is beginning to wake up to the challenges of the 21st century. The Paris Agreement signals a monumental shift in global action on climate change, while the costs of solar and wind are falling rapidly. Fossil fuel generation is facing an existential crisis, while low-carbon companies are already reaping the profits of the ongoing transition. Prudent investors are presented with a new set of opportunities for the taking.

Who does it primarily serve?

ET Index Research serves both the investor and the wider public at large. We are helping investors manage the greatest investment risk of the 21st century while playing our part to avoid the worst effects of catastrophic climate change.

What difference does ET Index Research want to make?

ET Index Research wants to accelerate the low-carbon transition, maximising investor returns in a carbon-constrained world while stopping climate change. Our aim is to allocate capital to the economy of tomorrow, rather than that of yesterday. This change must occur throughout global supply chains, bringing us toward a zero-carbon economy as fast as possible.

What are the barriers to making that difference?

The main barriers we face to action are the challenge any new entrant has in the financial system, a lack of track record. It is worth noting that our low carbon indexes have been live for over a year and performing well; backtested, they have outperformed relevant benchmarks for the past five years running. We have been ranking companies on their carbon emissions since 2010, with our latest ranking out in November.

Who’s helping you overcome those barriers?

A range of prudent investors realising the risks and opportunities of climate change in regards to their portfolios. The Fossil Fuel Divestment movement has been instrumental in shifting the discussion around finance and climate change, while international cooperation, exemplified in the Paris Agreement, is rapidly shifting the investment landscape.

Are companies doing enough to reduce their emissions?

In short, no. While some forward-looking companies are increasingly responding to climate change, cutting their carbon emissions and investing heavily in renewables, most have a long way to go. This is precisely why we create the ET Carbon Rankings each year to highlight the leaders and laggards. It also highlights the need for a credible mechanism to allocate capital from high-carbon to low-carbon companies, steering the whole economy to action.
