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 document analyzes the potential impact of the Trump administration's reversal of climate policies, such as the repeal of the Clean Power Plan, on U.S. emissions. It synthesizes data from seven organizations, estimating that 2025 emissions under Trump's policies would range from 5.6 to 6.8 GtCO2e, exceeding the U.S. Paris Agreement target. It also examines the potential for states, cities, and companies—represented by the 'We Are Still In' campaign—to offset these increases through clean energy transitions and local policy defense.

The document discusses the role of short-lived climate pollutants (SLCPs) in closing the 'emissions gap'—the difference between current Nationally Determined Contributions (NDCs) and the trajectories needed to keep global temperature rise below 2°C or 1.5°C. It identifies methane, tropospheric ozone, black carbon, and hydrofluorocarbons as primary targets for reduction, noting that while some strategies target single pollutants, most affect multiple. The text emphasizes that SLCP reductions, especially when combined with CO2 reductions, can limit long-term warming.

The 'Cooling for All' initiative, launched in 2017 by Sustainable Energy for All and supported by the Kigali Cooling Efficiency Program, seeks to integrate growing cooling demands into a clean energy transition. The initiative aims to align the Paris Climate Agreement, the Sustainable Development Goals, and the Kigali Amendment to the Montreal Protocol. To achieve this, a Global Panel on Access to Cooling has been established to produce an evidence-based report by 2018 focusing on sustainable cooling for the poorest countries. The initiative highlights the risk of locking countries into high-carbon cooling pathways and the potential to avoid 1°C of global warming by combining HFC phase-downs with energy efficiency gains.

The Centre for Environmental Rights (CER) supports the objectives of the Climate Change Mitigation Policies and Measures (PAMs) study but argues that its current methodology is too narrow. The CER contends that limiting the analysis to carbon dioxide, methane, and nitrous oxide excludes other critical greenhouse gases and pollutants, such as hydrofluorocarbons, perfluorocarbons, sulphur hexafluoride, black carbon, and hydrochlorofluorocarbons, which could undermine the accuracy of the modelling and miss significant mitigation opportunities.

A U.S. Court of Appeals ruling vacating the EPA's SNAP program threatens to prevent the avoidance of up to 9.5 billion metric tons of HFC emissions by 2050 and may hinder the U.S. ability to meet its commitments under the Kigali Amendment to the Montreal Protocol.

The document discusses the role of the private sector in achieving climate compatible development following the Paris Agreement. It notes that while new technologies and financial instruments are emerging, public policy is required to address market failures, counter opposing lobbies, and manage the social winners and losers resulting from industrial disruption.

The report develops a methodology using the LEAP-IBC (Integrated Benefit Calculator) tool to assess the impact of short-lived climate pollutants (SLCPs) in Estonia. Focusing on the residential and transport sectors, it compares 'Business As Usual' (BAU) and energy efficiency (EE) scenarios. Findings indicate that while BAU leads to a 4-6% increase in emissions by 2030, the EE scenario could reduce NOx, PM2.5, and black carbon emissions by 13-15%. The report emphasizes that the most significant health risks are driven by fine particulate matter (PM2.5) and black carbon, and recommends strategic urban planning and building renovations to mitigate these risks.

The text examines 'problem shifting' within the context of sustainable natural resource management and the Anthropocene. It evaluates whether existing international legal instruments, such as no-transfer provisions and inter-treaty cooperation, are sufficient to manage planetary-scale environmental risks. Using case studies on marine geoengineering and hydrofluorocarbons (HFCs), the analysis concludes that international law is currently inadequate and suggests the need for a new legal principle to address the trans-sectoral transformation of harm, similar to the development of the no-harm and intergenerational equity norms.

The document outlines how aligning the UNFCCC and Montreal Protocol regimes can help the refrigeration, air conditioning and foam (RAC&F) sector contribute to the Paris Agreement's temperature targets. It highlights that rising demand for cooling, driven by urbanization and population growth, increases CO2 and hydrofluorocarbon (HFC) emissions. The guide emphasizes the importance of the Kigali Amendment to the Montreal Protocol, which aims to phase down HFCs to avoid significant temperature increases.

The United States Mid-Century Strategy (MCS) provides a roadmap for deep decarbonization by 2050, focusing on three primary pillars: transitioning to a low-carbon energy system, enhancing the land carbon sink, and reducing non-CO2 emissions. The strategy emphasizes a combination of aggressive energy efficiency, near-complete decarbonization of the electricity grid, and the deployment of carbon removal technologies like BECCS. It argues that these goals are compatible with robust economic growth and suggests that a carbon price starting at $20 per metric ton in 2017 could put energy CO2 emissions on a consistent pathway. The report also highlights the critical role of U.S. forests and soils in sequestering carbon and the necessity of international cooperation to drive down technology costs and prevent emissions leakage.

One year after the Paris Agreement's adoption, the Climate Action Tracker (CAT) finds that national climate policies have made little progress. If NDCs are fully implemented, global warming by 2100 is estimated at 2.8°C, while current policies would lead to 3.6°C. A significant emissions gap remains for 2025 and 2030. The report highlights specific national trajectories, noting that most assessed NDCs are inadequate or medium in ambition, with particular concerns regarding the US, Russia, and Saudi Arabia, while noting positive renewable energy growth in India.

The World Resources Institute highlights the agreement by 197 parties to the Montreal Protocol in Kigali, Rwanda, to phase down hydrofluorocarbons (HFCs). The amendment aims to reduce global HFC levels by 80 to 85 percent by 2047, potentially avoiding up to 0.5 degrees Celsius of global warming by 2100.

The document argues that the draft Regulations unfairly place the burden of GHG emission calculations on data providers rather than the competent authority. It recommends shifting the data provider's role to reporting activity data at a facility level, expanding the scope of GHGs to include fluorinated gases, and ensuring full public disclosure of emission data to meet South Africa's obligations under the Paris Agreement and its Nationally Determined Contribution (NDC).

The Obama Administration set a goal to reduce methane emissions from the oil and gas sector by 40-45% from 2012 levels by 2025. While the EPA proposed standards for new and modified sources, it has failed to address existing sources, which a 2014 ICF International study predicts will represent 90% of the sector's total methane emissions in 2018. Analysis by CATF and the Rhodium Group indicates that voluntary industry programs are insufficient to bridge the 'methane emissions gap', as even 100% participation would leave a gap of 54 million metric tons of CO2e. The author asserts that nationwide standards on existing oil and gas equipment would reduce emissions by 77 million metric tons of CO2e, sufficient to meet the Administration's goal.

The World Resources Institute proposes six domestic actions for the Obama administration in 2016: implementing the Clean Power Plan, reducing methane emissions from existing gas infrastructure, banning more potent hydrofluorocarbons (HFCs), preparing industrial emission standards, finalizing fuel efficiency for heavy-duty trucks and aircraft, and increasing local climate resilience support. It also urges the U.S. to sign the Paris Agreement, meet Green Climate Fund commitments, and mobilize resources for Mission Innovation to sustain global momentum.

The SEI Initiative on Low Emission Development Pathways (LED-P) provides tools and research to help governments, particularly in developing countries, simultaneously address greenhouse gas emissions, short-lived climate pollutants (SLCPs), and air pollution. A central output is the LEAP-Integrated Benefits Calculator (LEAP-IBC), which quantifies the health, vegetation, and climate benefits of specific mitigation measures. The initiative focuses on filling data gaps, building technical capacity, and developing policy frameworks to move beyond aspirational scenarios toward credible transition pathways.

The document outlines the implementation of President Obama's Climate Action Plan (CAP), focusing on three primary goals: cutting U.S. carbon pollution, preparing for climate impacts, and leading international efforts. Key achievements include the finalization of the Clean Power Plan to reduce power sector emissions by 32% by 2030, the establishment of the State, Local, and Tribal Leaders Task Force on Climate Preparedness and Resilience, and the formation of bilateral climate agreements with China, India, and Brazil. The report details a series of executive orders, agency regulations, and budget requests aimed at reducing greenhouse gas emissions and enhancing national infrastructure resilience.

Carbon Market Watch argues that international carbon markets must be supplementary to domestic action and governed by strict eligibility, accounting, and integrity rules to avoid the failures of previous mechanisms like the CDM and EU ETS. The organization recommends excluding REDD-plus and agriculture from carbon markets, implementing a 'negative list' of ineligible project types, and establishing a UN-led standard-setting body to prevent double-counting and ensure net atmospheric benefits.

The United States can meet its target of reducing greenhouse gas emissions by 26–28 percent below 2005 levels by 2025 through a combination of existing federal laws and state actions. The report proposes a 10-point action plan focusing on the power sector, energy efficiency, HFCs, and methane reduction. For deeper reductions beyond 2025, the authors argue that new legislation, such as a carbon price, could reduce emissions by 40–42 percent by 2030 and 50–53 percent by 2040 without sacrificing robust economic growth.
