The briefing introduces action targets, which require an entity to reduce emissions by an agreed percentage of its actual emissions during a commitment period. By using an 'observable baseline' of actual emissions rather than projected ones, action targets eliminate the uncertainty associated with future economic growth. A comparison of a 2% target for Brazil, China, India, and Mexico shows that fixed targets can lead to either burdensome reductions or 'hot air' depending on GDP growth, while action targets maintain a consistent level of effort. The authors suggest action targets are compatible with the Kyoto Protocol and suitable for modest developing country commitments, though further research is needed on their environmental impact and administrative costs.

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 report calculates that between 1882 and 2002, ExxonMobil emitted 21.53 billion tonnes of carbon equivalent, representing approximately 5% of global CO2 emissions. It argues that the company has actively undermined climate science and the Kyoto Protocol despite increasing production to record levels after scientific consensus on human-induced climate change was established. The findings link these emissions to 3.4%-3.7% of human-attributable global temperature increases and 2% of sea-level rise, with the latter projected to reach 3.2%-3.6% by the year 2200.

The document outlines the causes and consequences of global climate change, highlighting the role of greenhouse gas emissions and the influence of the fossil fuel lobby. It categorizes career paths for scientists and engineers into four areas of positive contribution: understanding the problem, technological solutions, economic solutions, and social/political solutions, while warning against the influence of vested interests.

SGR argues that the UK government's approach to climate change is too cautious and fails to challenge the unsustainable nature of economic growth. The organization advocates for a 'Contraction and Convergence' model for global emissions, a shift in taxation from labour to resource use, and the complete replacement of fossil fuels and nuclear power with renewables. SGR specifically criticizes the government's reliance on 'accounting tricks' for non-CO2 gases, the lack of restrictions on air travel, and the potential dangers of climate engineering technologies.

The document assesses the role of the United States in the global effort to combat climate change following the 1997 Kyoto Protocol. It argues that the U.S. has failed to lead, contributing to 27% of annual global greenhouse gas emissions while resisting binding domestic action. The authors highlight critical loopholes in the Kyoto Protocol, such as the use of surplus emissions allowances from former socialist economies and ambiguous forest activity definitions. To ensure the treaty's success, the brief recommends that the U.S. implement mandatory domestic programs, defer demands for immediate binding commitments from developing countries, and support the Global Environment Facility.

The Hypercar concept, developed by the Rocky Mountain Institute (RMI), proposes a 'whole-system' approach to vehicle design to achieve fuel economies of 90 to 200 mpg. This is accomplished through the synergy of advanced polymeric composites to reduce mass by 50-65%, aerodynamic improvements to cut drag by 40-50%, and hybrid-electric drivesystems that recover up to 50% of braking energy. The document asserts that these vehicles can maintain safety standards, including in collisions with heavier cars, and could be compatible with various fuels, including hydrogen via fuel cells. RMI estimates that production-volume Hypercars could appear in the early 2000s, with costs comparable to conventional vehicles.

The paper compares two approaches to estimating national energy sector greenhouse gas emissions, finding that while global CO2 totals for 1988 are within 2% of Oak Ridge National Laboratory's estimates, national-level results vary by over 10% for 52 out of 139 countries. These discrepancies are attributed to differences in energy statistics, the treatment of bunker fuels, and the handling of non-energy products. Additionally, the study includes CO, CH4, and N2O emissions from fossil fuel combustion, which contribute an additional global heating effect of approximately 8% compared to CO2 emissions.

The paper asserts that most global warming can be abated at negative net cost by replacing inefficient resource use with advanced technologies in energy, farming, and forestry. It details specific potentials for saving electricity and oil, argues for a 'best buys first' investment strategy to avoid opportunity costs, and proposes market-based implementation techniques such as 'feebates' and 'negawatts'. The authors emphasize that these measures support global equity and development, particularly in the USSR and developing nations, while providing significant co-benefits in environmental protection and security.

The report proposes a framework for setting long-term climate targets based on the adaptive capacities of natural ecosystems. It recommends a maximum global temperature increase of 1.0°C to 2.0°C above pre-industrial levels and a sea-level rise limit of 0.2 to 0.5 meters above 1990 levels. The document analyzes the role of various greenhouse gases, introduces the Global Warming Potential (GWP) and Sea-level Rise Potential (SRP) indices, and discusses the socio-economic challenges of implementing these targets in developing countries and centrally planned economies.

The briefing assesses the viability of nuclear power as a solution to global warming, concluding that it is an ineffective strategy compared to energy efficiency. Analysis shows that even under highly optimistic assumptions—such as reduced construction times and costs—massive nuclear investment cannot prevent CO2 growth in high or medium energy demand scenarios. In the United States, the author asserts that investment in electrical efficiency displaces nearly seven times more carbon per dollar than investment in nuclear power. The document emphasizes that the primary driver of future emissions is the level of energy demand, and that efficiency improvements in the commercial, industrial, and transportation sectors offer vast, low-cost opportunities to reduce carbon output.

The report analyzes four Canadian environmental regulations—Coal Phase-Out, Clean Electricity, VOC, and Methane—finding they provide between $18 billion and $21 billion in direct health benefits by 2050. It argues that these savings could be used to address healthcare shortages, such as hiring 2,200 to 2,500 doctors, and cautions against the use of discount rates that undervalue the health of future generations.

The document analyzes the climate impact of Arctic oil and gas production, focusing on short-lived climate forcers (SLCFs) like methane and black carbon. It details emission sources—such as associated gas flaring, venting from storage tanks, and diesel engine exhaust—and proposes mitigation strategies including vapor recovery units, diesel particulate filters, and the use of ultra-low sulfur diesel. The paper emphasizes that while some technologies are standard in lower latitudes, Arctic implementation faces higher costs and infrastructure challenges.

A study commissioned by the Clean Air Task Force and conducted by Carbon Limits finds that finding and fixing natural gas leaks is a cost-effective strategy for reducing methane pollution. Based on data from over 4,000 inspections, the analysis shows that repairing most leaks is profitable for companies because the value of the conserved gas outweighs the repair costs. Quarterly LDAR surveys are estimated to abate methane at a net cost of less than $280 per metric ton, while monthly inspections at well sites and gas plants cost between $800 and $900 per metric ton—both figures remaining below the EPA's estimated societal damage cost of $970 per metric ton of methane. The document argues that current US federal regulations are insufficient, as only gas processing plants built since 1984 are required to perform leak inspections, and advocates for more robust federal rules based on the empirical evidence of low abatement costs.

The report argues that the Arctic is warming twice as fast as lower latitudes, with black carbon and methane having a disproportionate impact. It proposes that the U.S., during its 2015-2017 Arctic Council Chairmanship, should champion best practices in the oil and gas sector, advocate for a heavy fuel oil ban in shipping, promote clean energy for residential heating, and implement strategies to curb open burning.

The document assesses the environmental and economic impacts of flaring associated gas in the Bakken and Eagle Ford formations, concluding that routine flaring is unnecessary due to the availability of mature alternatives like CNG trucking, NGL recovery, and gas-to-power generation. It argues that current regulations, such as those in North Dakota, are inadequate and calls for robust nationwide standards from the BLM and EPA to mandate gas capture.

The Clean Air Task Force (CATF) utilizes a specialized gas analyser kit, specifically the ABB GLA-131 model, to detect methane and carbon dioxide emissions. The tool uses laser absorption spectroscopy to identify gas concentrations with high precision, including methane detection at levels below 1ppb. While the analyser can detect diffused emissions kilometers away from a source and confirm the gas identity, it is used for qualitative detection of concentrations rather than the quantification of emission rates, which would require additional meteorological data and scientific expertise. CATF employs the analyser as a complement to optical gas imaging (OGI) cameras to provide a more comprehensive view of emissions from sources such as landfills, gas capture wells, and anaerobic digesters.

The report finds that Native American communities are more likely to live within a half-mile of oil and gas facilities than the general population of their encompassing states, leading to disproportionate exposure to methane, volatile organic compounds, and toxic air pollutants. This impact is exacerbated by high poverty rates and lack of health insurance, which limit housing options and access to medical care for conditions like asthma. Specifically, the analysis highlights the Navajo Nation, the Northern Ute (Uintah-Ouray), and the Fort Berthold Indian Reservation as areas of significant risk.

The report highlights that tropospheric ozone is a potent greenhouse gas and air pollutant responsible for approximately 0.23°C of present-day warming and nearly 500,000 premature deaths annually. It is not emitted directly but forms from precursors like methane, nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), and carbon monoxide (CO). The document identifies a significant gap in global climate strategies, noting that tropospheric ozone is largely absent from the Paris Agreement and most Nationally Determined Contributions (NDCs). It provides sector-specific policy levers—ranging from methane capture in oil and gas to electric vehicle adoption in transport—and presents case studies from Los Angeles, Mexico City, Beijing, and Europe to demonstrate the effectiveness of targeted pollution control. The report concludes with recommendations for policymakers to adopt multi-pollutant approaches, for scientists to fill knowledge gaps in regional climate effects, and for funders to increase the currently insufficient international development funding for outdoor air pollution.

The agriculture sector in Pakistan contributed nearly 42 per cent of national greenhouse gas emissions in 2012. To address this, the document identifies twelve mitigation options, prioritizing five cost-effective measures: improving irrigation/water management, reducing methane from rice cultivation, implementing agroforestry, promoting better manure management, and limiting basmati rice crop burning. Together, these five priority measures are projected to reduce emissions by 11.83 MtCO2e by 2030, representing a 4.3 per cent reduction from the business-as-usual scenario.
