Greenovation

Collectively, cities take up a relatively tiny amount of land on the earth, yet emit 72 percent of greenhouse gas emissions. Clearly, cities need to be at the center of any broad effort to reduce climate change. This book argues that too many cities are only implementing random acts of greenness that will do little to address the climate crisis. It instead calls for “greenovation”—using the city as a test bed for adopting and perfecting green technologies for more energy-efficient buildings, transportation, and infrastructure more broadly. Further, the text contends that while many city mayors cite income inequality as a pressing problem, few cities are connecting climate action and social justice—another aspect of greenovation. Focusing on the biggest producers of greenhouse gases in cities, buildings, energy, and transportation, the book examines how greenovating cities are reducing emissions overall and lays out an agenda for fostering and implementing urban innovations that can help reverse the path toward irrevocable climate damage. Drawing on interviews with practitioners in more than 20 North American and European cities, the book identifies the strategies and policies they are employing and how support from state, provincial, and national governments has supported or thwarted their efforts.

Eco-innovation districts are defined areas in which cities concentrate state-of-the-art technologies in green building, smart infrastructure, and renewable energy to create sustainable, resilient, and inclusive districts that accelerate action on climate change and sustainability. This chapter addresses four questions: Does the district perform better than or as well as the rest of the city on per capita carbon emissions? How well does the district serve as a test bed for green technologies that can reduce greenhouse gas emissions? Does the city employ a deliberate process of organizational learning that allows city planners and elected officials to apply effective practices and lessons learned from district-scale experimentation? What measures have been put in place to ensure a diversity of income levels? It also examines whether the experimentation undertaken in European eco-innovation districts can be replicated in the United States.

In the last year, hundreds of climate emergency declarations have been made by local and national governments around the world. Instigated through grassroots activism, these declarations have become a focus of aspirations for radical climate action. However, concerns have also raised been about the desirability of emergency declarations in responding to the climate crisis, including at a local scale. In this paper we consider the enactment of emergency declarations by two local government authorities in Aotearoa New Zealand that have recent experience with multiple crises. Drawing on in-depth interviews with activists, councillors and officials, our findings show that adopting the ‘international language’ of climate emergency can be a source of hope but also tension. In particular, we highlight the struggle of local practitioners to overlay an emergency approach, something that is already contested in response to sudden onset disasters, with the scale, complexity and temporality of climate change. Our analysis suggests that retrofitting an emergency approach to the climate crisis at the local scale has the potential to reproduce status quo politics, and calls for a greater understanding of the diversity of approaches to emergency in climate politics.

Energy-efficient buildings utilise the potential of renewable sources, among which heat pumps hold an important position. As this technology has a secondary effect on the environment through its noise immission, locations of outdoor units in the exterior should be subjected to the assessment. The present article deals with the options of placing heat pumps in the exterior and the placement assessment methods. The noise burden identification through the assessment of the time exposure is presented in the example of an in situ measurement.

Flooding is a dangerous phenomenon, causing emergency situations and causing material damage, capable of damaging health, and even death of people. To reduce the risk and economic damage from flooding, it is necessary to forecast flooding areas. An effective method of forecasting emergency situations due to flooding is the method of remote sensing of the Earth with integration into geoinformation systems. With the help of satellite imagery, a model of flooding was determined based on the example of Tavda, the Sverdlovsk Region. Space images are loaded into the geoinformation system and on their basis a series of thematic layers is created, which contains information about the zones of possible flooding at given water level marks. The determination of the area of flooding is based on the calculation of the availability of maximum water levels at hydrological stations. According to the calculated security data, for each hydrological post, flood zones are constructed by interpolation between pre-calculated flood zones of standard security. The results of the work can be used by the Main Directorate of the Ministry for Emergency Situations of Russia for the Sverdlovsk Region.

‘Lockdown’ periods in response to COVID-19 have provided a unique opportunity to study the impacts of economic activity on environmental pollution (e.g., NO2, aerosols, noise, light). The effects on NO2 and aerosols have been very noticeable and readily demonstrated, but that on light pollution has proven challenging to determine. The main reason for this difficulty is that the primary source of nighttime satellite imagery of the earth is the SNPP-VIIRS/DNB instrument, which acquires data late at night after most human nocturnal activity has already occurred and much associated lighting has been turned off. Here, to analyze the effect of lockdown on urban light emissions, we use ground and satellite data for Granada, Spain, during the COVID-19 induced confinement of the city’s population from 14 March until 31 May 2020. We find a clear decrease in light pollution due both to a decrease in light emissions from the city and to a decrease in anthropogenic aerosol content in the atmosphere which resulted in less light being scattered. A clear correlation between the abundance of PM10 particles and sky brightness is observed, such that the more polluted the atmosphere the brighter the urban night sky. An empirical expression is determined that relates PM10 particle abundance and sky brightness at three different wavelength bands.
