A coalition of health and environmental experts calls on West Midlands mayoral candidates to implement Clean Air Zones and invest in sustainable transport to address widespread air pollution. The letter highlights that legal pollution limits are exceeded in every local authority in the region, contributing to cardiovascular disease and asthma, and urges candidates to support a new national Clean Air Act.

The document analyzes proposed budget cuts in the FY2018 'skinny' budget, highlighting the elimination of bipartisan programs for low-income energy assistance, climate research, and rural transportation. It details specific reductions across the USDA, DOE, EPA, NASA, and the Department of State, arguing that the 'America First' approach prioritizes physical security and fossil fuels over climate resilience and international cooperation.

The document details a workshop organized by the Stockholm Environment Institute Tallinn Centre as part of the HERON project. It outlines proposed energy efficiency (EE) scenarios for Estonia's buildings and transport sectors, contrasting them with business-as-usual (BAU) paths. Expert panel discussions concluded that the proposed renovation rates for buildings are overly ambitious due to funding and skill shortages, while transport goals require better integration of modes and increased local government authority over cycling and public transport infrastructure.

The document argues that promoting active travel—defined as walking, cycling, and public transit—creates a 'quadruple win' by reducing chronic disease, improving air quality, slowing climate change, and increasing health equity. It provides a framework for health professionals to encourage patients to integrate physical activity into their daily routines and to advocate for urban planning policies, such as the '5 Ds' of community design (density, land use diversity, design, destination accessibility, and distance to transit). A significant portion of the guide focuses on the Growth Plan for the Greater Golden Horseshoe in Ontario, explaining how intensification and complete community planning can facilitate a shift away from automobile dependence.

The document outlines how the built environment influences travel behavior, emphasizing that walkable neighborhood design increases the frequency of walking, cycling, and transit use. It details the '5 D's' of community design—Density, Diversity, Design, Destination, and Distance—as the primary factors impacting these choices. Key elements include population density to support services, land use diversity to place destinations in close proximity, safety-enhancing design features like bicycle lanes and traffic calming, and the accessibility of destinations and transit stops within specific distance thresholds.

ClientEarth and a coalition of organisations argue that the current VED system incentivises diesel vehicles, which contribute to illegal air pollution levels and significant health costs in the UK. They propose an additional £800 first-year VED charge on new diesel cars to fund air quality measures and accelerate the transition to ultra-low emission vehicles.

The document provides an overview of autonomous vehicle (AV) technology and its potential societal impacts. It highlights risks including increased vehicle miles traveled, potential for increased climate emissions if gasoline-powered, and algorithmic biases in detecting people of color and children. To address these, the Union of Concerned Scientists proposes seven guiding principles focusing on safety, clean vehicles, integrated transit, improved access, just transition for workers, public accountability, and livable communities.

The report analyzes the implementation of congestion charging and low emission zones in London, Singapore, and Stockholm. It highlights the importance of national legal safeguards, strong local political will, transparent revenue allocation, and effective public communication. Key findings include significant reductions in traffic volume and pollutants in all three cities, though the specific technologies used—such as London's ANPR and Singapore's DSRC—varied based on local needs and urban landscapes.

The document lists various entities awarded for pioneering green bond activities in 2016. Key achievements include the first green sovereign bond from Poland, the largest overall issuer (Shanghai Pudong Development Bank), and the first green bonds from several countries including Colombia, Costa Rica, Morocco, and the Philippines. It also recognizes the People's Bank of China for regulation and CICERO for its 'Shades of green' assessment model.

The document outlines how urban transportation infrastructure in Alberta is vulnerable to rising temperatures and extreme weather, such as flooding and heat waves. It argues that resilience can be achieved through 'robustness' (using tools like the PIEVC protocol and green infrastructure), 'redundancy' (diversifying transportation modes and fuel sources), and 'resourcefulness' (engaging citizens via mobile apps and supporting shared mobility). The briefing recommends that Calgary and Edmonton undertake full vulnerability assessments, promote compact urban forms, and implement multi-modal networks to mitigate climate risks.

Indonesia faces imminent energy security challenges, with demand for electricity and transport fuel expected to grow rapidly by 2030. While the government has set ambitious targets for renewable energy (23% by 2025) and emission reductions (29-41% by 2030), current investments follow a 'business as usual' fossil fuel path. Structural barriers include policy inconsistency, limited fiscal space, and a political culture of transactional politics and decentralisation that often favours the exploitation of domestic coal. However, opportunities exist in geothermal energy, waste-to-energy, and energy efficiency, alongside governance reforms like the 'One Map' initiative and increased foreign direct investment to mitigate the financial risks of transitioning to a low-carbon economy.

The report argues that interoperable transit data is essential for the realization of 'mobility as a service' (MaaS), which allows users to seamlessly combine various transportation modes. It identifies significant barriers to this goal, including poor data quality, a lack of standardization for ride-hailing and car-sharing, and misaligned incentives. The authors estimate that achieving full data interoperability could boost ridership of alternative transportation by 5% to 10%, representing a market opportunity of $3 billion to $6 billion in the U.S. To address these challenges, the report proposes the formation of a cross-industry consortium to establish and maintain data standards and innovate in user-interface design and payment technology.

The document outlines a multi-level governance approach to urban climate action, emphasizing that while cities are primary sites of emissions and vulnerability, they require supportive national policy frameworks and international financing to achieve transformative change. It details local jurisdictional powers, national enabling environments, and specific access modalities for the Green Climate Fund.

The guide examines the politics of climate change in three Latin American mega-cities, finding that while political leadership and local framing drive policy adoption, implementation is often hindered by a lack of broad social coalitions and low electoral salience of climate issues.

The report proposes eight strategic policy axes for Mexico City to transition toward a sustainable urban model: Transit-Oriented Development, territorial delimitation, public transport integration, mixed land use, small blocks, non-motorized mobility, automobile use control, and recreational public spaces. It establishes quantitative benchmarks for 2018, 2024, and 2030 to reduce car dependency and improve air quality and public health. Key recommendations include implementing a single payment card for integrated transport, establishing strict urban growth boundaries, and promoting 'urban recycling' to create walkable neighborhoods.

The document outlines the role of human activity in increasing greenhouse gas emissions and global warming, the resulting environmental and health risks, and the emission reduction targets required to limit temperature increases to 1.5 or 2 degrees Celsius by 2050.

The document outlines the challenges of rapid urbanization in the Global South, where a growing proportion of the poor live in cities with limited financial resources. It proposes a framework to categorize cities by economic productivity and population growth, focusing on 'struggling' and 'emerging' cities. The authors argue that prioritizing equitable access to core services—housing, water, sanitation, energy, and transportation—is a critical entry point for transformative urban change, citing the examples of Medellín and Surat as cities that achieved broad transformation through targeted reforms and strong political coalitions.

The document argues that urban GHG mitigation is most effective when governments at different levels operate according to their comparative advantages. It categorizes city roles into policy leaders, critical implementers, and strategic partners, mapping these roles to specific abatement potentials in transport, buildings, and waste. The authors emphasize that national governments must provide enabling actions—specifically financial support, technical capacity, and policy alignment—to unlock this potential. Case studies of China, the United States, and Brazil illustrate varying degrees of vertical integration and identify specific national-level gaps that hinder city-scale climate action.
