The report outlines a multi-pronged approach to building cooling, emphasizing the transition from active air conditioning to passive design and high-efficiency technology. It details various technical solutions—ranging from 'super-efficient' AC units and passive cooling techniques to wearable devices and the use of waste cold from LNG terminals. The document also analyzes policy levers such as Minimum Energy Performance Standards (MEPS) and behavior change campaigns like Japan's 'Cool Biz'. Finally, it explores innovative business models to improve affordability for the poor, including Pay-As-You-Go (PAYG), ESCO models, and public-private partnerships in countries like India, Mexico, and Bangladesh.

The transportation sector accounts for 36% of greenhouse gas emissions in large cities. To address this, the handbook outlines several strategic actions: electrifying municipal fleets, reducing internal combustion engine (ICE) vehicles through bans or restrictions, managing urban freight emissions, expanding EV charging infrastructure, creating car-free downtown zones, and enhancing public transit and mobility alternatives like bikeshare and pedestrian-friendly streets.

The Carbon-Free City Handbook outlines a strategic framework for cities to reduce greenhouse gas emissions through immediate, economically viable actions. It categorizes recommendations into buildings, transportation and mobility, electricity, industry, and biological resources, emphasizing the importance of setting bold 100% targets to drive transformational change rather than incremental progress.

The policy brief analyzes the decentralized solar market in Brazil, finding that consumer uptake is driven primarily by demand-side factors rather than natural resource availability. Analysis of 5,563 municipalities reveals that areas with higher GDP, larger populations, and higher electricity tariffs have more photovoltaic units, while regions with the highest solar potential, such as the Center and Northeast, have lower adoption rates. The authors recommend that climate risk mitigation policies address these demand-side barriers to encourage solar penetration in the poorest regions with the highest solar potential.

An analysis of 5,563 Brazilian municipalities by the Climate Policy Initiative (CPI) and PUC-Rio reveals that distributed solar PV adoption is driven primarily by demand factors rather than natural resource availability. The study finds that municipalities with higher GDP, larger populations, and higher electricity tariffs have more PV units, while those with the highest solar radiation often have fewer. As of June 2017, only 1,478 municipalities had at least one distributed PV unit, with the highest concentration in Rio de Janeiro. The authors recommend that climate risk mitigation policies incorporate demand-side incentives and target poorer regions with high solar potential.

The document proposes the Green FIDC, a specialized securitization vehicle that transforms risky greenfield projects into bankable assets for institutional investors. By utilizing a two-stage process—initial development finance followed by refinancing through senior shares in the Brazilian capital markets—the instrument aims to reduce reliance on the Brazilian National Development Bank (BNDES) and lower the cost of capital for renewable energy and energy efficiency initiatives. The analysis highlights two pilot opportunities: a 90 MW solar PV project in Ceará and a municipal street lighting LED retrofit in Rio de Janeiro. Financial modeling suggests the instrument is commercially viable, with the potential to leverage USD 1 billion in investment and avoid 10 million tons of CO2 if scaled.

The research finds that demand-side factors are the primary drivers of distributed solar PV adoption in Brazil, often outweighing the availability of solar resources. Analysis shows that municipalities with higher GDP, larger populations, and higher electricity tariffs have more PV units, while solar radiation only becomes a significant positive predictor when comparing municipalities within the same electricity distributor's concession area. The authors argue that current subsidy policies in the Northeast region artificially lower tariffs, hindering PV growth in areas with the highest solar potential. They conclude that climate mitigation policies must address demand-side frictions and tariff structures rather than focusing solely on natural resource availability.

The document discusses Brazil's strategy to meet its Nationally Determined Contribution (NDC) goals by expanding its biofuel market. It highlights a study conducted in Rio de Janeiro showing that the increase in flex-car adoption—which reached 94% of new car registrations in 2008—reduces retail prices for both ethanol and gasoline. The study finds that a 10-percentage point increase in flex-car market share lowered ethanol prices by approximately eight cents of Brazilian reais and reduced gasoline margins by two cents, benefiting consumers who do not own flex-fuel vehicles.

The study finds that the penetration of flex-fuel vehicles increased competition among fuel stations, leading to a reduction in retail prices and margins for both ethanol and gasoline. The effect was more pronounced for ethanol. While the price correlation between the two fuels increased, the authors found no strong evidence that the price spread between gasoline and ethanol decreased as flex-fuel adoption grew. Structural estimation suggests that pass-through from costs to prices is approximately 0.5, consistent with oligopoly theory.

The report examines the shift in global climate governance from the top-down targets of the Kyoto Protocol to the Nationally Determined Contributions (NDCs) of the Paris Agreement. It highlights the 'ambition gap' in current pledges and argues that the success of the agreement depends on integrating the actions of non-state actors—such as cities, regions, and businesses—into national frameworks. The document details specific subnational initiatives like the C40 network and Brazil's CB27, while providing a case study of Singapore's role in the negotiations.

The briefing highlights research indicating that global sea levels could rise by several meters within 50 to 150 years if emissions grow, potentially submerging major global cities and displacing 20% of the world's population. It emphasizes that these impacts could occur even if the 2 degree C target is met. For Canada, the document details 2010 emission sources and advocates for a societal transformation, specifically noting that closing coal-fired power plants in Ontario and Alberta provides a rapid pathway for emission reductions and health benefits.

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.

The guidelines establish a 'first green, then smart' approach, where smart technologies are used to optimize the outcomes of sustainable urban design. The framework covers six smart categories: telecommunications, mobility, governance, energy management, safety, and public services, supported by global case studies to demonstrate economic and environmental viability.

The report argues that sustainable urban design, guided by 'The 8 Principles' (Walk, Connect, Transit, Cycle, Mix, Densify, Compact, Shift), delivers significant environmental, economic, and social benefits. It provides a comprehensive review of data from Chinese cities and international examples to demonstrate that reducing car dependence and increasing density improves air quality, boosts property values, and enhances public health. The document specifically highlights China's unprecedented scale of urbanization as a critical area for applying these principles to avoid the pitfalls of 'superblocks' and car-centric planning.

The authors contend that current 'business-as-usual' urbanization, characterized by car-oriented infrastructure, leads to high greenhouse gas emissions, economic losses from congestion, and safety risks. They advocate for 'smart urban mobility'—which combines technology with coordinated planning—to 'leapfrog' car-centric development. Examples of successful interventions include Mexico City's Metrobús BRT, Beijing's low emission zone, and Medellín's Metrocable. The document highlights 2015 as a pivotal year due to the finalization of the UN Sustainable Development Goals, upcoming climate negotiations, and the UN Decade of Action on Road Safety.

Tijuca National Park in Rio de Janeiro was restored starting in the 1860s to address severe water crises caused by deforestation for coffee and sugarcane. Through a combination of active planting and passive recolonization, 3,200 hectares were restored, resulting in improved water supplies, air quality, and the reintroduction of numerous native species. The project succeeded due to strong leadership from the Brazilian Imperial Court, technical assistance from the Botanical Garden of Rio de Janeiro, and adaptive management to combat fire threats. However, the document notes that early restoration involved the expropriation of land and the use of slave labor.

EMBARQ Brasil provided technical assistance to Rio de Janeiro, Belo Horizonte, and Brasilia to design and implement bus rapid transit (BRT) systems. By 2014, 154 kilometers of BRT corridors were launched, reducing commute times by 50 percent for 1.5 million people and improving air quality and road safety. The success of these projects has led to plans for an additional 211 kilometers of BRT networks in these cities.

The document provides a comprehensive review of empirical studies demonstrating that compact, transit-oriented, and walkable urban design leads to lower greenhouse gas emissions, reduced infrastructure costs, and increased labor productivity. It highlights specific findings from China, such as the negative energy impacts of 'superblocks' in Jinan and the property value premiums associated with Bus Rapid Transit (BRT) in Beijing and Guangzhou. The report also emphasizes the cost-effectiveness of BRT over light rail and the public health benefits of non-motorized transit, while identifying research gaps in developer-side profit data and the specific productivity effects of density in Chinese cities.
