Cities are increasingly taking actions such as building code enforcement, urban planning, and public transit expansion to reduce emissions of carbon dioxide in their communities and municipal operations. However, many cities lack the quantitative information needed to estimate policy impacts and prioritize city actions in terms of carbon abatement potential and cost effectiveness.

In this report, we evaluate policies to reduce GHG emissions in urban areas according to multiple criteria, based on an extensive literature review. Municipal governments implement policies (regulations, charges, subsidies, etc.) to induce actions (such as improved energy efficiency in buildings or a shift to public transit).

This report discusses how to manage growing competition for curb access in cities. The rise of ride services and the growth in urban goods delivery are challenging traditional ways of managing curb space. We describe how curb use is changing, how our capacity to monitor its use may need to evolve and discuss what the future of the curb may look like.

Cities are the global centers of communication, commerce and culture. They are also a significant, and growing, source of energy consumption and greenhouse gas (GHG) emissions. A city’s ability to take effective action on mitigating climate change, and monitor progress, depends on having access to good quality data on GHG emissions.

Most people now live in cities. In the next one hundred years, cities will rapidly grow in size and complexity. Now, more than ever, there is a need to assess the future impact of engineering constructs before they are built.

Urban Efficiency II: Seven Innovative City Programmes for Existing Building Energy Efficiency builds on research in the successful predecessor “Urban Efficiency” Report and captures seven new detailed city case studies from C40 member cities. It is primarily targeted at city-level policy makers and decision makers across the world.

This report presents results from applying a new technique called Contribution Analysis to local community greenhouse gas (GHG) inventory data. Contribution Analysis separates out the impact of different drivers of change between multiple inventory years. The drivers looked at include population/ commercial growth, energy usage per person, and the carbon intensity of energy sources.

Residential and commercial buildings accounted for over 2,000 Million Metric Tons (MMT) of carbon equivalent emissions and 40% of the total energy consumed in the United States in 2016. New construction and major renovations in buildings have a long-term impact on emissions as many of the features incorporated at time of construction will impact energy consumption for decades.

The emerging ‘grand challenges’ of climate change, resource scarcity and population growth present a risk nexus to cities in the Anthropocene. This article discusses the potential that rapid urbanisation presents to help mitigate these risks through large-scale transitions if future urban development is delivered using evidence-based policies that promote regenerative urban outcomes (e.g.

Unprecedented levels of urbanisation coupled with revolutions in transport, energy, and data technology offer new opportunities to reshape cities. Cities of the future need to be planned strategically to support environmental and social well-being as well as economic productivity. To do so, cities must encourage compact and connected urban growth.

To increase levels of biking while improving safety, cities around the world have started building barrier-protected bicycle-exclusive cycle tracks between the sidewalk and the street. With cycle tracks, the unanswered urban planning issues include whether and where to plant street trees and, if planted, whether the trees in that location provide associated benefits.
