The report evaluates the Clean Development Mechanism's (CDM) ability to provide a "development dividend" to developing countries. It finds that the current project pipeline is dominated by low-cost, end-of-pipe industrial projects (such as HFC23 decomposition) that offer minimal sustainable development benefits and are concentrated in a few larger developing nations. The report identifies high transaction costs and a cumbersome project-by-project approval process as significant barriers to the deployment of small-scale, community-based projects. To address these issues, the authors recommend transitioning toward policy-based and sectoral CDM approaches, reforming the CDM Executive Board into a professional body, and establishing internationally agreed principles for sustainable development.

The report argues that California can significantly reduce its global warming impact by mandating the adoption of existing and near-term vehicle technologies. Modeling shows that currently available improvements in engines, transmissions, and air conditioning could reduce fleet average heat-trapping emissions by 20%, while advanced technologies available within five years could achieve a 40% reduction. These improvements are presented as cost-effective, with fuel savings offsetting initial costs within a few years, and would provide a model for other U.S. states and Canada.

The document analyzes energy demand and GHG emissions in Pakistan's residential, commercial, and agriculture (RCA) sectors, which accounted for roughly 9 per cent of national emissions in 2012. It identifies 12 mitigation options, prioritizing nine based on abatement potential and cost-effectiveness. Key measures include replacing inefficient lighting, stoves, and cooling appliances, as well as improving irrigation pumps. The report projects that without intervention, RCA sector emissions will grow from 29 MtCO2e in 2012 to 61 MtCO2e by 2030. The most significant abatement potential in 2030 is attributed to efficient stoves (12.86 MtCO2e) and efficient lighting (2.19 MtCO2e).

The report details a bottom-up integrated model developed in Analytica to project greenhouse gas emissions in South Africa to 2050. It incorporates a Mitigation Potential Analysis (MPA), GHG emission pathways, and a socio-economic model linked via a Social Accounting Matrix (SAM). The model assesses various sectors—including energy, industry, transport, waste, and AFOLU—applying specific mitigation measures and policies such as the Carbon Tax Act of 2019 and the IRP 2023. It provides a framework for evaluating the socio-economic impacts of decarbonisation pathways on employment, output, and household consumption across different income deciles.

The document distinguishes between 'safe bets'—technologies available commercially without major implementation constraints—and 'risky bets'—solutions with uncertain prospects that could still be significant for carbon neutrality. It notes that safe bets provide the majority of reductions by 2030, while risky bets increase in importance by 2050.

The document highlights that over 3.2 billion people in 52 high-impact countries face cooling access challenges, with 1.05 billion at high risk.

The report recommends national action plans, public-private partnerships, and targeted financing for the most vulnerable populations to ensure equitable access to sustainable cooling.

The report identifies significant cooling access gaps in Ghana, with 12.9 million people at high risk due to poverty and lack of electricity. It argues for a transition to sustainable cooling by integrating passive design, higher energy efficiency standards, and the phase-out of HFC refrigerants. Key focus areas include developing cold chains for agriculture and healthcare to reduce food loss and improve vaccine distribution, while addressing the urban heat island effect in cities like Accra and Kumasi.

The report highlights that approximately 3 billion people lack essential cooling, leading to millions of deaths annually from heatwaves, vaccine spoilage, and food insecurity. It identifies 9 high-risk countries—including India, China, and Nigeria—and categorizes vulnerable populations into rural poor, urban poor, and low-middle income groups. The document argues that meeting this demand sustainably is critical to achieving the Paris Agreement and the Kigali Amendment, as inefficient cooling could lead to a massive increase in energy demand and greenhouse gas emissions. Proposed solutions include passive cooling (e.g., cool roofs), district cooling, and innovative financing like PAYGO models.

The report identifies a significant global cooling access gap affecting approximately 3.4 billion people, categorized into the rural poor, slum dwellers, carbon captives, and middle-income groups. It highlights the critical role of cooling in achieving Sustainable Development Goals (SDGs), particularly regarding heat-related mortality, vaccine preservation, and agricultural food loss. The document emphasizes the intersection of the SDGs, the Paris Agreement, and the Kigali Amendment to the Montreal Protocol, warning that unmanaged demand for inefficient air conditioning could lead to a massive increase in energy consumption and greenhouse gas emissions. It proposes a holistic 'thinking thermally' approach, combining passive cooling, district cooling, and efficient technology with innovative financing models like PAYGO to provide sustainable cooling for all.

The Effects screen in LEAP allows users to view, edit, and add data for 258 default environmental effects, including greenhouse gases and local air pollutants. The software integrates GWP values from IPCC Assessment Reports (AR1 through AR6), enabling users to calculate emissions in physical tonnes or CO2 equivalents. While the main system focuses on effects directly associated with energy use, the Impact Benefits Calculator (IBC) module can be used for indirect health and air quality impacts at a national scale.

Colombia is utilizing the CCAC SNAP initiative and the LEAP-IBC tool to identify priority emitting sectors and integrate short-lived climate pollutant (SLCP) mitigation into its national air quality and climate change policies. The process involves quantifying emission scenarios to inform legal frameworks and funding, with specific focus on agriculture (rice paddies, sugar cane, manure management), transport, brick kilns, and cookstoves. To date, 60 regional climate change plans have been reviewed to identify implementation opportunities, and 15 of the 100 measures in Colombia's INDC resulted from SNAP Phase I.

Ghana is utilizing the SNAP initiative to develop a national plan for mitigating short-lived climate pollutants (SLCPs), integrating these efforts into its National Determined Contributions (NDCs) and the Ghana Shared Growth and Development Agenda. The Ghana EPA is employing the LEAP-IBC model to calculate emissions and benefits across both energy and non-energy sectors. Key sectoral actions include the potential implementation of Euro-benchmarked emission standards for transport, the distribution of 200,000 solar lanterns to replace kerosene, and a Green Cooling Programme to replace high-GWP HFC air conditioners. To support these goals, the Ministry of Finance has established a climate change unit as the National Designated Authority for the Green Climate Fund.

Nigeria is implementing the SNAP initiative by establishing a coordination office within the Federal Ministry of Environment to identify emission sources and develop a national action plan. The process involves integrating the LEAP-IBC tool to model the impacts of emission scenarios on health, climate, and crop yields. Priority sectors for mitigation include cookstoves, agriculture, transport, brick kilns, and the oil and gas industry, with a focus on improving regulation, enforcement, and legislative frameworks to align with Nigeria's Intended Nationally Determined Contributions (INDCs).
