The paper identifies five key levers—power and leadership, communication and engagement, capacity building, financing implementation, and demonstration effect—essential for successful climate action in cities. Drawing on seven CDKN-supported projects across Asia, Africa, and Latin America, it argues that city governments face significant barriers, including short political cycles, fragmented governance, and limited financial resources. The framework serves as a checklist for donors and practitioners to create investable and implementable climate propositions, highlighting the importance of local champions, tailored business cases, and cross-city collaboration to scale successful interventions like India's Heat Action Plans.

The document is a 'Comments and Responses Report' addressing objections to the Thabametsi Power Station's climate and palaeontological assessments. The developer, Thabametsi Power Company, defends the project's alignment with the 2010 Integrated Resource Plan (IRP) and argues that its greenhouse gas (GHG) emissions, while high, are consistent with international standards and comparable to other South African coal plants. It rejects claims that it must calculate the 'social cost of carbon' or assess community-level climate resilience, stating these fall outside the approved Scope of Work. The report also addresses water scarcity risks in the Lephalale region, asserting that Phase 1 will use existing water allocations from the MCWAP-1 scheme and employ dry-cooling technology to minimize consumption.

The report finds that while voluntary sustainability standards (VSSs) are increasingly adopted in key agricultural sectors, they remain a marginal force globally, covering less than 1% of global agricultural area as of 2014. VSSs show strong alignment with habitat conservation, with 87% prohibiting production on recently converted forestland, but are poorly equipped to address climate change, with no standards requiring strict GHG emission reductions. The analysis reveals that standards typically mandate practices rather than performance outcomes, and their impact is often limited by a reliance on developed-country demand and a tendency to be adopted where compliance is least costly. The report suggests five policy options, including supporting biodiversity-driven implementation and developing integrated data systems, to better leverage VSSs for biodiversity protection.

The Carbon-CAP project assesses the effectiveness and feasibility of consumption-based carbon accounting (CBCA) and demand-side policies to address emissions embodied in trade. By analyzing sectors such as food, buildings, and transport, the report identifies a suite of promising policy instruments—ranging from regulatory standards to carbon-intensive material charges—that could potentially reduce the EU's carbon footprint by up to 48% theoretically, or 4-10% when accounting for realistic behavioral responses by 2050. The study emphasizes that while production-based policies are standard, CBCA provides a critical macro-level indicator of an economy's carbon intensity and the responsibility of consuming nations for global emissions.

The report evaluates a proposed wood biorefinery in Estonia with a projected capacity of 750,000 tonnes per year. Using the CEPI methodology, the study finds that the plant would have a negative fossil carbon footprint of -0.39 tonnes of CO2-e per tonne of finished product, primarily because the renewable electricity it exports to the grid replaces oil shale-based power. The plant is also estimated to sequester 1.3 tonnes of biogenic CO2-e per tonne of product. Compared to a 'zero scenario' where wood is exported to Nordic countries, the project is expected to reduce Estonia's overall greenhouse gas emissions by approximately 1.6% and increase the share of renewable electricity in national consumption to 26%.

Carbon Market Watch and Transport & Environment critique the EU's guidelines on Upstream Emission Reductions (UERs), stating they are too weak to force the oil industry to change practices due to loopholes regarding carbon offsets and double counting. While the Fuel Quality Directive requires a 6% carbon footprint reduction by 2020 compared to 2010, the authors argue that national governments must now make the guidelines legally binding and limit eligible savings to Clean Development Mechanism projects in Least Developed Countries to ensure transparency and additionality.

The report finds that battery-electric vehicles (BEVs) produce significantly lower lifetime global warming emissions than comparable gasoline cars, despite higher emissions during the manufacturing process. On average, BEVs sold in the U.S. produce less than half the emissions of gasoline vehicles, with the extra manufacturing burden offset within 6 to 16 months of driving. The environmental benefit of EVs increases as the U.S. electricity grid shifts from coal to renewable energy sources.

The document describes a comparative study of carbon and water footprints in La Paz, Quito, and Lima, highlighting how these measurements informed urban planning and the creation of municipal action plans. It identifies high-level political will, stakeholder buy-in, and the transition from planning to implementation as critical factors for successful urban climate resilience.

The Cities Footprint Project measured the carbon and water footprints of La Paz, Quito, and Lima to support municipal climate mitigation and adaptation. Findings revealed that transport is the primary carbon contributor and residential grey water the primary water footprint driver across all three cities. While the project led to action plans and pilot projects, implementation faced challenges such as administrative changes and data gaps. Success was linked to high-level political will and the presence of internal champions.

Ben & Jerry’s advocates for more stringent US Environmental Protection Agency fuel economy regulations for freight trucks, noting that transportation accounts for 17% of the company's carbon footprint. The company argues that a 40% reduction in fuel consumption by 2025 is feasible and would reduce freight rates by nearly 7%, potentially saving the average American household $250 annually.

The policy brief argues that current carbon pricing mechanisms, which use free allowances to prevent carbon leakage in industrial sectors, eliminate the price signal for mitigation beyond primary production efficiency. To address this, the authors propose 'Inclusion of Consumption,' where a consumption charge is levied on carbon-intensive materials (such as steel, aluminum, and clinker) based on benchmark emission values and the carbon price. This charge would apply to all domestic consumption regardless of origin, making it compatible with WTO law. The mechanism would use duty suspension arrangements to track materials through the value chain, with the charge becoming due only when the good is released for consumption. The brief notes precedents in Asia (South Korea, China, Tokyo) regarding electricity consumption and discusses potential implementation in Europe and the United States.

The author criticizes the European Union's criminalization of migration and the failure of neoliberal development models in the Maghreb. It highlights the link between environmental degradation—such as desertification and water scarcity—and forced migration, noting that 'environmental refugees' may reach 250 million by 2050. The text calls for a transition to 'post-development' cooperation that reduces Europe's ecological footprint while improving the Human Development Index (HDI) in the Maghreb, moving beyond the interests of extractive elites and the 'Washington Consensus'.

The author contends that the EU must move away from criminalizing migrants and implementing neoliberal economic models in the Maghreb. Instead, the document proposes a cooperation framework based on reciprocity and ecological awareness, highlighting how environmental issues—such as desertification in coastal areas and water scarcity linked to fracking in Algeria—drive social instability and migration. It criticizes the 'Washington consensus' and the lack of international legal recognition for environmental refugees, who are estimated to reach 250 million by 2050. The text also notes that political instability, corruption, and bilateral conflicts between nations like Morocco and Algeria hinder regional cooperation and the development of interregional projects.

The document details the vulnerability of agricultural and forest products to climate change, noting significant potential losses in cocoa, coffee, cotton, and wine production, as well as specific environmental pressures on flower exports from Kenya and silk production in India.

The document evaluates the environmental sustainability of first-generation biofuels produced in the Basque Country using an innovative methodology that integrates the SIMSNIC agronomic model with life cycle analysis. The study focuses on bioethanol from wheat and biodiesel from rapeseed in the La Llanada Alavesa area. It finds that while biofuels are more energy efficient than fossil fuels, meeting the EU's mandatory 35% greenhouse gas (GHG) reduction target is unlikely under current mineral fertilisation conditions, particularly in nitrate-vulnerable areas. Organic fertilisation increases the likelihood of meeting GHG targets but exacerbates water contamination, soil acidification, and land-use competition. The authors conclude that the agricultural stage, specifically nitrogen fertilisation and climatology, is the primary driver of the carbon footprint due to nitrous oxide emissions.

The document details the first carbon and water footprint assessments for the city and municipal government of La Paz, Bolivia, using 2012 as a base year. It identifies the transport sector as the primary source of greenhouse gas emissions and the residential sector as the main contributor to the water footprint. The project led to the creation of a reduction action plan, the inclusion of environmental measures in the 2014 municipal budget, and the implementation of pilot projects such as a waste-to-energy system at the Municipal Zoo and peri-urban organic farming. Key challenges identified include data scarcity, the need for high-level political commitment, and the impact of a polarized political environment.

The document outlines a project in Hue, Vietnam, that sought to balance socioeconomic development from tourism with environmental protection. It highlights the successful promotion of 'garden houses' as a climate mitigation and tourism strategy, the importance of national policy frameworks adapted to local contexts, and the role of leadership in guiding sustainable growth. However, it notes a critical trade-off: while local initiatives can reduce emissions within the city, they cannot address the emissions generated by tourists traveling to the destination.

The document outlines the scale and sources of agricultural greenhouse gas emissions, identifying the sector as the second largest global emitter. It highlights the role of methane and nitrous oxide, lists the top emitting countries, and discusses the impact of land-use change and dietary shifts. Finally, it presents the GHG Protocol guidelines as a tool for farms to inventory and reduce their carbon footprint through improved production practices and demand-side changes.

The document examines the 'Sustainable Urban Tourism through Low Carbon Initiatives' project in Hue, Vietnam. It identifies that the tourism sector emitted approximately 492,200 tons of CO2e in 2011, with travel being the largest source. The city promoted 'garden houses' as a viable mitigation strategy because they act as carbon sinks, reduce waste through composting, and lower freight emissions by producing local food. This approach also supports local employment, particularly for middle-aged women and non-motorised transport operators. While the initiative reduced in-situ emissions and strengthened the city's commitment to sustainable tourism, the document notes a trade-off: increased tourist attraction may lead to higher overall emissions from travel to the city, which exceeds local reductions.

The report details how Illinois municipalities use Community Choice Aggregation (CCA) to pool electricity purchasing power, enabling them to negotiate lower rates and switch to cleaner energy sources. Since 2013, over 90 Illinois towns have transitioned to 100% renewable electricity via Renewable Energy Credits (RECs), increasing demand for wind and solar by over 6 terawatt hours. The document provides case studies from Oak Park and Chicago, analyzes CCA adoption in other states like California and Massachusetts, and offers strategic recommendations for municipalities to move beyond RECs toward local renewable energy investments.
