Background

I have worked for over 20-years on strategies for addressing global climate change, drawing upon economics, technology, policy and industrial ecology perspectives. Much of my current work involves biophysical analysis of economies towards deep decarbonization. My previous research helped the development of a standard approach for city-wide greenhouse inventorying – as well as mitigation strategies. Holding qualifications in civil engineering, economics and business, I have conducted consulting work on sustainable infrastructure and cities for several national governments, as well as the World Bank and others. In 2011/12, I was seconded to the OECD in Paris, to work on Cities, Green Growth and Policies for Encouraging Investment in Low Carbon Infrastructure. I have been a visiting professor at Oxford University and ETH Zürich. I previously served as President of the . I am also a Senior Fellow at the  and author of .

Current projects

Biophysical Economics

I am developing new biophysical methods, from first principles, that assist governments to move economies towards deep decarbonization. Central to these methods is understanding of the mutualistic relationship between  in economies.

Global Infrastructure

I continue to work on planning and investment strategies for the global development of sustainable infrastructure systems.  This builds on work first developed at the OECD (below) that was published in  and recently applied to .  Related to this research, I co-authored an article in  on peak waste.

Past projects

Electric Cities

Building on studies of the metabolism of megacities (below) we are examining the potential for wide-scale electrification of cities, using low-carbon power sources.  For this work, we partnered with the  and published in outlets including  and .

This research also identified a key threshold for the carbon intensity of electricity supply which supports low carbon growth (published in  and reported by 13 news outlets including Globe & Mail and CBC Radio).

Metabolism of Megacities

In partnership with the Enel Foundation, I led a group of 28 researchers in a study of the energy and material flows of the world’s 27 megacities. The sheer magnitude of these flows (e.g., 9% of global electricity, 10% of gasoline, 13% of solid waste) showed the importance of megacities in addressing global environmental challenges. Our work was published in the  and picked up by several media outlets including: Quartz, The Atlantic, The Guardian, NBC News, CNBC, Discovery News, Le Scienze, and the BBC’s Newsday.

Greenhouse Gas Emissions from Global Cities

Building upon studies of urban metabolism, I led a group of international scholars to investigate how and why greenhouse gas (GHG) emissions differ between global cities. Our work was published in   and   and was featured in the Economist magazine. Our methodology was adopted by the World Bank, UNEP and UN-Habitat as a standard approach for conducting city-wide GHG inventories. Subsequently we published an article on strategies for reducing GHG emission from cities in .

Mobilising Investment in Low Carbon, Climate Resilient Infrastructure

In 2011-12, I was seconded to the Organisation for Economic Co-operation and Development (OECD) in Paris. At OECD, I primarily supported the Working Party on Climate, Investment and Development (which has delegates from the 34 OECD countries, including Canada). I led one paper and contributed to a second, both concerned with policies for encouraging increased private sector  . My work was incorporated into OECD material for the Mayors & Ministers meeting (Chicago), Clean Energy Ministerial (Paris), and the Rio +20 Environment conference.

Getting to Carbon Neutral: A Guide for Canadian Municipalities

In 2010, the Sustainable Infrastructure Research group produced a quantitative  to help Canadian municipalities understand and reduce their greenhouse emissions. The Guide was produced in collaboration with Toronto Region Conservation and partner municipalities in the Greater Toronto Region. A chapter of the book on best practices was published by the .

Urban Metabolism

Over several years I conducted research on  including the first comparison of worldwide city metabolism. I have helped several organizations develop programs to use urban metabolism for environmental reporting, including Toronto Region Conservation, The World Bank, and UCLA / California Energy Commission.

Sustainable Infrastructure and Neighbourhoods

A variety of earlier projects included work on green buildings, neighbourhood metabolism, urban water systems and sustainable urban transportation, using methods of life cycle assessment and material flow analysis.
