Tanzir Chowdhury

Senior Environmental Economist

Tanzir’s work at Eunomia mainly focuses on statistical and econometric analysis, cost-benefit analysis (CBA), health impact modelling, market analysis, ex-ante policy appraisal, and ex-post impact evaluation.

Tanzir is highly proficient in advanced econometric modelling techniques involving cross-section, time-series and panel data, as well as econometric impact evaluation techniques, such as, propensity score matching, double differencing, and regression discontinuity design. Besides econometric modelling, Tanzir has vast experience of developing ex-ante options appraisal models in Excel based on cost-benefit analysis. He is also experienced in advanced non-market valuation methods, such as, hedonic pricing techniques, value of statistical life models, travel cost methods, health production function models, damage cost estimation, and contingent valuation methods.

Key Areas of work include:

  • Economic analysis of environmental taxes, subsidies and other market-based instruments;
  • Modelling health impacts of air pollution;
  • Demand estimation and forecasting;
  • Valuing natural capital and green infrastructure;
  • Climate adaptation and resilience; and
  • Green financing mechanisms.


Recent Experience

Tanzir has led the econometric analysis in a number of projects. Examples include forecasting demand for security licences issued by the Security Industry Authority (SIA) using Seasonal ARMAX models, evaluating multi-dimensional success of catchment partnerships under the Catchment Based Approach (CaBA) using simultaneous equation models, forecasting household waste generation for the North London Waste Authority (NLWA) using panel data for seven North London boroughs, estimating short- and long-run elasticity of navigational charges in Environment Agency waterways using panel data models, and modelling volatility and liquidity of PRN prices with PRN trading floor data using GARCH and ARIMAX models.

Tanzir also specialises in evaluating the health and economic impacts of air pollution and has worked on a research project for the National Institute for Health and Care Excellence (NICE) which analysed the cost effectiveness of interventions delivered by local authorities to reduce road-traffic-related emissions. In the project, he was the lead modeller for developing an impact assessment model for estimating the health and non-health related impacts of various interventions to reduce air pollution. In another project for a UK-based active travel charity Sustrans, he was the Technical Lead in developing a model to evaluate the health and air quality benefits of various interventions to encourage a shift towards active travel choices. More recently, Tanzir has been working on a project for the DG Environment of the European Commission which evaluates the effectiveness of EU Ambient Air Quality Directives in reducing air pollution across Europe.

Tanzir has also worked on a number of projects involving economic and environmental modelling. Recent examples include, modelling policy options for implementing a Scottish specific Aggregates Levy, modelling economic and environmental impacts of potential changes to the Waste Disposal Levy in New Zealand, estimating the GVA and employment impacts of integrating circular economy principles into the UK’s emerging industrial strategy, and developing a natural capital compensation scheme for alternative land management options.

Other key projects Tanzir has recently worked on include:


 Previous Experience

Tanzir joined Eunomia in November 2014 while undertaking his PhD in Economics at the University of Warwick. His research focus was on dynamic general equilibrium modelling in financial asset markets. Tanzir also has a Postgraduate Diploma in Advanced Economics from University College London and an MA in Economics from Delhi School of Economics, India. In all these educational degrees, his primary focus was on advanced econometric modelling and economic policy analysis.

Prior to joining Eunomia, Tanzir had years of experience (working in four different countries) in economics research, teaching and consultancy in organisations such as the University of Warwick, University College London, South Asian Network for Development and Environmental Economics (SANDEE), BRAC University and GE Capital. While working at SANDEE and BRAC University, Tanzir led a research project on estimating the health benefits of reducing vehicular air pollution with panel household survey data using advanced random-effects econometric models.
