About us


Helping Sustainability Professionals seeking to influence strategy development, finance and investment.

Who we write for and why

We write for sustainability professionals working in companies, the finance industry, government, academia and NGOs. 

Finance and sustainability people use different words and think differently. We write about sustainability with a finance perspective bridging the gap between sustainability, finance and strategy.

A key ask from our readers is "how do I influence strategy?" Sustainability professionals want to drive real change - make their business more sustainable - but are often excluded from the strategy process.

There are two levers to pull in making a business more sustainable within the context of making returns:

  • Improve the business itself = predominately the finance world
  • Improve the broader environment = predominately the political world

You can visualise this by thinking about a filing box sitting on top of a truck. If you wanted the box to move further away from you then you can either move the box along the roof of the truck or move the truck away from you or ideally both.

In the same way, we can either attract appropriate finance to make a business more sustainable or we can lobby for appropriate political change to make the broader environment more sustainable. Or we can do both!

There is also an important timescale aspect to making 'sustainability' strategic decisions:

  • There could be an immediate win.
  • I can position my business early for upcoming systemic change and avoid business obsolescence.

The aim of our writing is to help you understand these aspects.


How we can help you

An often repeated complaint is that it's really hard for sustainability professionals to actually make a difference.

We help you think holistically, laterally and see new insights.

We can help you understand how to pitch sustainability ideas in a way that finance and operational people will buy in to.

We help you make sustainability core to your organisation's strategy, driving long-term value.

What we don't write on

We do not cover ESG scoring, the reasons for action (climate change, environmental destruction, habitat loss) etc. These are well covered by other publications. Our focus is on viable private sector led solutions. 


What we do write on

We have two strands of writing:

The first looks at how sustainability professionals can best influence change. Finance and strategy people have a distinct language and way of thinking, and so Sustainability Professionals need to learn to communicate in a way that best captures their attention. This includes looking at the provision of government aid, tax breaks and Blended Capital. 

The second is looking at specific issues within the sustainable transitions, so agriculture, natural capital, mining, health, electricity , hard to decarbonise, transport and our built environment. Here we explore how best to link the options we face with the long term financial case for change.
