Our People

Tanzir Chowdhury
Principal Environmental Economist
I apply economic principles to solve environmental problems, especially through designing incentive mechanisms to drive behaviour change. I also have a keen interest in nature photography, and whenever I get a chance I’m out in the nature with my camera.

Tanzir’s work at Eunomia focuses on policy design, cost-benefit analysis, econometric modelling and forecasting, environmental valuation, ex-ante policy appraisal, and ex-post impact evaluation.

Tanzir is highly proficient in advanced econometric modelling and forecasting techniques involving cross-section, time-series, and panel data, as well as quasi-experimental impact evaluation techniques, such as, propensity score matching, double differencing, and regression discontinuity design.

Besides econometric modelling, Tanzir has vast experience of developing options appraisal models in Excel using cost-benefit analysis, cost-effectiveness analysis, and multi-criteria analysis. He is also experienced in advanced non-market valuation techniques, such as, hedonic prices, value of statistical life models, travel cost methods, damage cost estimation, and contingent valuation methods.

Key Areas of work include:

  • Environmental taxes, subsidies and other market-based instruments;
  • Waste policy design and appraisal;
  • Green financing mechanisms;
  • Air quality;
  • Sustainable transport;
  • Industrial emissions;
  • Material flows analysis;
  • Climate adaptation and resilience;
  • Natural capital and green infrastructure; and
  • Business case development using HMT’s five case model.

Recent Experience

Tanzir has led the econometric analysis in several projects. Recent examples include short- and long-term forecasting of waste arisings in England, econometric benchmarking of cost and performance of the recycling systems of municipalities in Ontario, econometric prediction of number of producers below the de-minimis threshold under the UK packaging EPR scheme, and analysis of factors affecting waste generation and recycling rates in Nordic countries.

Tanzir also specialises in evaluating the health and economic impacts of air pollution. Recently, he led the economic modelling of local NO2 reduction plans for two UK local authorities, led modelling of health and air quality benefits of various interventions to encourage a shift towards active travel choices.

Tanzir has also worked on several projects involving economic, social and environmental impact assessment. Recent examples include impact assessment of revisions to EU Bathing Water Directive, cost-benefit analysis of circular textile policies in the UK, and assessment of alternative scheme designs for a Mattress EPR scheme in Scotland.

Tanzir also worked on analysing and designing potential environmental taxes and other market-based instruments for all 27 Member States, and led a project for implementing environmental tax reform in Cyprus focusing on air pollution, climate change, water quality, and waste management.

 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 (PhD Coursework) from University College London and an MA in Economics from Delhi School of Economics, India.

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.
