Quant Climate is a specialist consultancy that turns climate and environmental data into quantified, decision-ready evidence. We work at the intersection of climate science, statistics, and economics — helping organisations understand not just what might happen as the climate changes, but how likely each outcome is and what it means for their decisions.

Our approach

Most climate analysis hands you a single number and asks you to trust it. We do the opposite. Every estimate we produce comes with its uncertainty made explicit, because a decision made without knowing the range of possible outcomes is a decision made blind.

We build our models using Bayesian statistics. In practice, that means:

• We state our assumptions transparently, and let the data update them.
• We report a full distribution of plausible outcomes — credible intervals, not just point estimates.
• We can combine multiple, imperfect data sources into a single coherent picture.
• Our results remain interpretable and defensible to regulators, boards, and the public.

Where we work

Our projects span the places where climate meets consequence:

• Finance & insurance — physical and transition risk, portfolio exposure, and scenario stress-testing.
• Policy & government — measuring the real-world impact of environmental interventions, from air-quality zones to emissions rules.
• Industry & supply chains — understanding how climate drivers cascade into operational and economic disruption.

Selected work

• Air quality policy. Quantified how the UK’s Ultra Low Emission Zone reduced pollution levels across Greater London — separating the policy’s true effect from background trends.
• A warming Netherlands. Modelled the rising number of projected warm days, with full uncertainty around the trend.
• The Rhine and its shipping. Showed how warmer winters lower river water levels and shrink the window in which cargo ships can operate — with direct consequences for the supply chains that depend on the river.
