SOCIETE DE MATHEMATIQUES APPLIQUEES ET DE SCIENCES HUMAINES

Their core work

SMASH is a Paris-based applied mathematics consultancy that specializes in quantitative modelling for energy and climate policy. They build and refine integrated assessment models that translate complex climate scenarios into decision-relevant outputs for policymakers and financial institutions. Their work bridges mathematical modelling with socio-economic analysis — helping projects quantify distributional impacts of decarbonisation pathways and develop sustainability metrics for investment decisions.

What they specialise in

How they've shifted over time

SMASH entered H2020 through sustainable finance, developing energy investment metrics and benchmarks (SEI Metrics, 2015-2018). Their focus then shifted toward climate modelling and decarbonisation policy, moving from financial tools to integrated assessment models in DEEDS and NAVIGATE (2017-2023). This trajectory shows a clear migration from applied finance analytics toward deeper climate science modelling with policy relevance.

SMASH is moving from financial benchmarking toward next-generation climate models that incorporate social equity and transformation dynamics — positioning them at the intersection of climate science and policy design.

How they like to work

SMASH operates almost exclusively as a supporting expert rather than a project leader — they coordinated zero projects and participated mainly as a third party (2 of 3 projects). Despite their small footprint, they connect into large consortia averaging 13+ partners across 15 countries, suggesting they are brought in for specialized mathematical modelling capabilities. Their role pattern indicates they are a trusted niche contributor that larger teams call upon for quantitative analysis.

Despite only three projects, SMASH has touched 39 unique consortium partners across 15 countries, reflecting a broad European network built through large-scale climate and energy research consortia.

What sets them apart

SMASH occupies a rare niche: a private SME that provides applied mathematics expertise to large climate research consortia. Most integrated assessment modelling sits within universities or large research institutes, making a lean, specialized consultancy an unusual and flexible partner. Their ability to bridge quantitative modelling with human sciences (as their name suggests) makes them valuable for projects that need rigorous models but also socio-economic interpretation of results.

Highlights from their portfolio

• NAVIGATE
  Flagship EU project building next-generation integrated assessment models for climate policy — SMASH contributed as a third-party modelling expert in a large international consortium (2019-2023).
• SEI Metrics
  SMASH's only project as a direct participant and sole source of their EC funding (EUR 152,875), focused on creating investment metrics that bridge climate science and financial decision-making.
