About me

I am an Assistant Professor of Computer Science and Public Policy at the Hertie School. My work focuses on methods from statistics and machine learning to inform climate mitigation policy across the energy sector, and on climate-related AI policy. I am also a co-founder and chair of the organization Climate Change AI. Previously I was Postdoctoral Researcher and Lecturer in the Energy Politics Group at ETH Zürich. I obtained a PhD in Engineering and Public Policy and a Master's in Machine Learning from Carnegie Mellon University.

Data Lab

Hertie School Data Science Lab

The Hertie School Data Science Lab is a research center that leverages data science and machine learning to help answer policy problems. A new Master of Data Science for Public Policy (MDS) has also recently been established through the Lab, with the aim to train students in modern data science to tackle some of the most complex challenges of our time, including climate change, global migration, and combating disinformation. As a core faculty member, Lynn helps to run the MDS and contributes to the research and operation of the Data Science Lab.

Climate Change AI

Climate Change AI (CCAI) is a global initiative to catalyze impactful work at the intersection of climate change and machine learning. CCAI has led the creation of a global movement in climate change and machine learning, encompassing researchers, engineers, entrepreneurs, investors, policymakers, companies, and NGOs. Lynn is a co-founder and chair of CCAI.

Aligning artificial intelligence with climate change mitigation

We introduce a systematic framework for describing ML's effects on GHG emissions, comprising three categories: (A) computing-related impacts, (B) immediate impacts of applying ML, and (C) system-level impacts.

Automated identification of climate risk disclosures in annual corporate reports

It is important for policymakers to understand which financial policies are effective in increasing climate risk disclosure in corporate reporting. We use machine learning to automatically identify disclosures of five different types of climate-related risks.

Learning from urban form to predict building heights

In this paper, we present a machine learning based method for predicting building heights, which is based only on open-access geospatial data on urban form, such as building footprints and street networks

Truck traffic monitoring with satellite images

In this proof of concept, we show how object detection network can count trucks in satellite images and predict average annual daily truck traffic from those counts, adding to the understanding of how the road freight sector contributes to greenhouse gas emissions.

Decarbonizing intraregional freight systems with a focus on modal shift

With the appropriate incentives, energy savings and emissions reductions can be achieved by shifting freight to rail or water modes, both of which are far more efficient than road. We focus on the literature and data relevant to estimating the global decarbonization potential through modal shift, and estimate the world road and rail modal split to around 60:40.

Empirical prediction intervals improve energy forecasting

We lay the groundwork for evaluating the performance of energy forecasting methods with a probabilistic framework in the data-scarce setting of long-term forecasts.

Fifty years to prove Malthus right

A major question confronting sustainability research today is to what extent our planet, with a finite environmental resource base, can accommodate the faster than exponentially growing human population. In this paper, we reevaluate Malthus' maximum sustainable population - the carrying capacity K

Published by Global Partnership on AI (GPAI)

Climate change and digital transformation are the two most powerful trends of our century. The way in which we manage them, and their increasing interaction, will play a significant role in humanity’s future in the 21st century and beyond. We need to create pathways to combine the climate and digital transitions in a way that upholds our social and democratic values.

This report is intended to help guide the action of governments of GPAI Member States and beyond about how to support the responsible adoption of AI for climate action. It is the first step of a program of activities that GPAI would support in this space that we hope would forge concrete international cooperation programs in the form of joint investment in research, development, innovation, regulation, and capacity-building.

With the increasing deployment of artificial intelligence (AI) technologies across society, it is important to understand in which ways AI may accelerate or impede climate progress, and how various stakeholders can guide those developments. On the one hand, AI can facilitate climate change mitigation and adaptation strategies within a variety of sectors, such as energy, manufacturing, agriculture, forestry, and disaster management. On the other hand, AI can also contribute to rising greenhouse gas emissions through applications that benefit high-emitting sectors or drive increases in consumer demand, as well as via energy use associated with AI itself. Here, we provide a brief overview of AI’s multi-faceted relationship with climate change, and recommend policy levers to align the use of AI with climate change mitigation and adaptation pathways.

Climate change is one of the most urgent challenges of our time, and addressing it will require rapid and concerted action across many sectors of the economy. As AI has increasingly transformational effects on society, it is therefore critical to holistically account for the effects — both positive and negative — that AI may have on climate change. In this light, we would like to suggest that the proposed regulation more explicitly account for the potential risks of AI systems to increase greenhouse gas emissions. In addition, we believe that the legislation provides an opportunity to collect much-needed information for assessing the greenhouse gas emissions impacts of AI.
