About Gauss Research

Applied science that
changes decisions

We exist to bridge rigorous academic research and the urgent, real-world demands of climate policy, sustainable development and environmental governance, working alongside partners and institutions that share our commitment to science-driven change.

We develop innovative tools and algorithms grounded in the core sciences and strengthened by statistics, econometrics and artificial intelligence. Our work is not theoretical: it is deployed in real policy contexts, from EU-level reporting frameworks to national climate transparency systems in developing nations.

Our work spans climate change, energy, environment, environmental economics, climate finance and policy analysis, partnering with institutions, governments, international organisations and research networks across the world. We operate at every scale, from local initiatives to global frameworks, and across all levels of public administration.

Our tools are peer-reviewed, internationally published and operationally validated, recognised by organisations such as the UNFCCC Secretariat and the IPCC.

Economic Impact of Climate Change

Macroeconomic damage functions, sector by sector

A quantitative modelling framework linking physical climate projections to macroeconomic outcomes: GDP, sectoral output, employment and welfare, under different warming and policy scenarios.

Combines climate science with econometric and input-output modelling to produce country-level economic damage functions that can inform adaptation and mitigation cost-benefit analysis.

LOCUS

Local land use from satellite observation and computational analysis

A remote sensing and machine learning pipeline extracting high-resolution local land use and land cover data from satellite imagery, providing ground-truth inputs for GHG inventories, REDD+ accounting and environmental assessments in data-sparse contexts.

Addresses a critical bottleneck in climate reporting for developing nations: the absence of reliable, granular land use data at sub-national scale.

SPECTRA

Satellite-physics enhanced climate downscaling for regional adaptation

A physically-grounded, satellite-integrated climate downscaling pipeline that transforms coarse regional climate model outputs (CORDEX, around 25 km) into high-resolution projections at approximately 1 km for any country on Earth, using Copernicus satellite data as the spatial refinement layer, with no local weather stations required.

Delivers locally calibrated, multi-scenario projections of temperature, precipitation, humidity and evapotranspiration, plus actionable indices: heat wave frequency (WBGT), drought indicators (SPEI) and seasonal water balance, specifically designed for climate adaptation planning in data-sparse developing nations.

Long Term Backcasting Model

LTBM, pathway modelling from net-zero targets

A quantitative backcasting framework that works backward from defined long-term mitigation targets, such as net-zero by 2050, to derive consistent, sector-level policy pathways and milestone trajectories.

The methodological foundation was peer-reviewed and published in Mitigation and Adaptation Strategies for Global Change (Springer, 2023), applied to design a long-term low-emission development strategy (LT-LEDS) for Tajikistan under the Paris Agreement.

Why consistency between GHG inventories and projections is the hardest problem in climate reporting

Most countries submit NDCs with projections methodologically disconnected from their own GHG inventories. We explain why this happens and what it takes to solve it.
