Time is running out in the race to slash carbon emissions and repair biodiversity, with the goal of reaching net-zero by 2050 remaining as elusive as ever.

In Costing the Earth, leading impact investor Eric Archambeau argues that rather than making media-friendly pledges and grasping low-hanging fruit (such as aviation taxes), world leaders must radically overhaul finance instead.

Only by aligning investment decisions with the UN''s 17 Sustainable Development Goals, and ensuring that industrial and services companies measure and incorporate in their P&L statements the full environmental and social costs of their operations - costs that are currently passed on to taxpayers or absorbed by Nature - will we stand a chance of achieving the breakthroughs we need.

Zeroing in on the agri-food sector, one of the largest contributors to global greenhouse gas emissions, water consumption and biodiversity loss, Archambeau dissects the many hidden problems caused by our current financial system.

As the stakes continue to rise and the window for action narrows, Costing the Earth makes the case that the only viable and sustainable way to achieve net-zero is to adopt the model pioneered by impact investors, which takes the three Ps - profit, people and the planet - into account when valuing a company or tracking its performance. Only then will business leaders all over the world be incentivised to place sustainability and the regeneration of the planet''s resources at the heart of their operations and decision-making.
