Peak emissions in C40 Cities




An article in Engineering and Technology magazine reports that the greenhouse gas emissions from 27 major cities around the world have peaked despite growing populations and economies.


The cities are: Barcelona, Basel, Berlin, Boston, Chicago, Copenhagen, Heidelberg, London, Los Angeles, Madrid, Melbourne, Milan, Montréal, New Orleans, New York City, Oslo, Paris, Philadelphia, Portland, Rome, San Francisco, Stockholm, Sydney, Toronto, Vancouver, Warsaw, and Washington D.C.

All are members of C40, which set three principal criteria for inclusion in the list:

1 The emissions reached a maximum level at least 5 years before the most recently recorded year, in order to eliminate short-term fluctuations.
2 The peak level emissions are at least 10 per cent higher than the most recent inventory year. Again, this is to eliminate “false” peaks due to short-term fluctuations.
3 The city has made a public commitment to deliver further emission reductions.

Energy maps and calculators

  The production and use of different forms of energy have been mapped geographically for a variety of reasons, and some examples will be outlined briefly before describing a recent place-based energy calculator for the UK. Scales of mapping vary in the examples from the global through region, country, city and parish down to city block. Both energy production and use have been mapped by type, such as coal, gas and oil, wind and solar renewables, by the associated emissions, and by energy flows between geographical regions. The purpose and the intended audience vary from case to case. The Global Atlas for Renewable Energy is a resource coordinated by the International Renewable Energy Agency (IRENA) which “allows its users to find maps of renewable energy resources for locations across the world.” (Global Atlas for Renewable Energy, 2021). The Global Solar Atlas provides information on irradiation levels on land worldwide within a suitable range of latitudes, and calculates the o

Carbon Capture, Utilization and Storage

    Introduction The need to limit the harmful effects of climate change is a powerful motive for preventing carbon dioxide emissions from entering the atmosphere, and for removing CO2 that is already there, but there can be subsidiary aims associated with carbon capture, and there are many methods of accomplishing it. According to a definition published in 2014, “Carbon Capture, Utilization, and Storage (CCUS) encompasses methods and technologies to remove CO2 from … flue gas and from the atmosphere, followed by recycling the CO2 for utilization and determining safe and permanent storage options” (RCN-CCUS, 2014a). A definition of carbon capture and storage (CCS) used by Torvanger (2020) “refers to a group of technologies that reduce emissions of carbon dioxide from coal-fired or gas-fired power stations, or from process industries." The term sequestration is also used for the removal of CO2 from the atmosphere or from combustion gases, and permanent prevention of its ret

Climate fiction and climate action

The interactions between climate fiction and environmental activism are the subject of a paper by Alacovska and Holt (2023). They describe environmental activism as “grassroots, decentralised social movements” which attempt to address issues of “inequality and systemic injustice arising from anthropogenic climate change, environmental degradation and ecological collapse” by means of non-hierarchical collective organising. The main object of their paper is to propose methods for future research, but here we will only draw on their introduction to the subject and its background. They believe that the popular genre of climate fiction influences climate activism , with the potential to stimulate the imagination and to energise the “quest for the attainment of better climate alternatives”. This stands in contrast with much writing on climate change, which is concerned with data and “mathematical prediction models for forecasting and comprehending the gravity of global environmental challeng
