Estimating CO2 Emissions with Machine Learning


The Ph.D. student will work on a collaboration project between EURECOM and the National Institute of Environmental Studies (NIES) ( in Japan. The purpose of this project is to develop an algorithm for estimating CO2 emissions from radiance data observed by a satellite.  The overarching goal is to enable real-time monitoring and quantification of the emissions of CO2 (and other greenhouse gases) from various locations on the earth. The tools developed in the project are to be used for purposes related to the mitigation of climate change.

The project involves the following two tasks:

  1.  Emulation of a simulator that transforms CO2 emissions to radiance observations. While NIES owns such a simulator, it is computationally expensive for repeated use needed for estimating CO2 emissions in real time. Thus, the task here is to develop a surrogate model that emulates and is faster than the simulator; such a surrogate model is called emulator.  In particular, this project aims to develop an accurate emulator using machine learning. 
  2.  Estimation of CO2 emissions from radiance observations using the developed emulator.  Specifically, this project takes a Bayesian approach, using the emulator for defining a likelihood model. A key challenge here is that the Bayesian estimation has to be done for a large number of locations on the earth simultaneously. To address this challenge, this project aims to develop a Bayesian inference algorithm that is scalable.

While the Ph.D. student will be employed by and mainly working at EURECOM, the student will also work at NIES in Japan for a short term (few weeks to few months) every year. Travel expenses will be covered.

 About the Supervisor

The main supervisor is Dr.~Motonobu Kanagawa ((, an Assistant Professor at EURECOM. He has been working on statistical machine learning, with a focus on learning algorithms for which theoretical guarantees can be provided. He is interested in how to use machine learning for improving the reliability of computer simulation, with applications including simulations of traffic systems, natural disasters (e.g., tsunamis), finance (e.g., pension systems) and climate economics. 


  • Masters' degree in a relevant discipline (e.g., computer science, mathematics, environmental science).
  • Strong background in statistics, machine learning, and data science in general.
  • Strong programming skills (e.g., in Python).
