The World Resources Institute (WRI) responds to President Obama's State of the Union address by identifying key policy levers to meet U.S. emissions targets. WRI argues that while executive action is necessary, market-based legislation to price carbon would maximize economic benefits. To reach the 2020 target, WRI recommends enacting standards for existing power plants, reducing hydrofluorocarbons, addressing methane leaks from natural gas systems, and improving energy efficiency.

The document identifies short-lived climate pollutants (SLCPs)—including black carbon, methane, tropospheric ozone, and hydrofluorocarbons (HFCs)—as gases and particulates with atmospheric lifetimes of less than 20 years that contribute to approximately half of global warming. It argues that while CO2 reduction is vital for long-term stability, SLCP mitigation offers faster results to slow the rate of warming, particularly in sensitive regions like the Arctic and Himalayas. The text details the specific radiative forcing and warming potentials of these pollutants, their primary sources (such as oil and gas production and biomass burning), and the associated co-benefits for food security and public health.

The author proposes a two-track approach for President Obama's second term: immediate regulatory action via the EPA to reduce carbon dioxide from power plants and methane from the oil and gas industry, and a long-term strategy to revamp energy technology innovation. To achieve a target of 80 percent carbon dioxide reduction by 2050, the document suggests developing a portfolio of zero-carbon technologies, including carbon capture and storage, advanced nuclear energy, and synthetic hydrocarbon fuels, supported by more effective innovation policies and increased R&D funding.

The research introduces a modelling framework combining the NGAUGE field-scale model and a new LANDDAIRY farm-scale submodel to quantify greenhouse gas (GHG) emissions from Basque dairy farms. A case study of 17 farms in Bizkaia found mean total GHG emissions of 385 ± 175 t CO2-eq yr-1, with emissions per litre of energy-corrected milk ranging from 0.86 to 2.11 kg CO2-eq. The study identifies methane from enteric fermentation and emissions from purchased feed as the primary contributors to the carbon footprint, suggesting that purchased feed can serve as a proxy for estimating total farm emissions.

The paper assesses the technical parameters used to calculate emission reductions for improved cookstoves, specifically focusing on biomass fuel consumption, the fraction of non-renewable biomass, and emission factors. It identifies significant uncertainties in current Clean Development Mechanism (CDM) and Gold Standard methodologies, noting that reliance on laboratory tests like the Water Boiling Test often fails to reflect real-world performance. The authors argue that current accounting may under-credit projects by ignoring non-CO2 gases and black carbon, and by using fossil fuel emission factors as surrogates for biomass. The document recommends incorporating uncertainty accounting, refining monitoring through data loggers, and developing more localized, sub-national assessments for non-renewable biomass.

The document examines the technical challenges and gaps in accounting for greenhouse gas emissions in cookstove projects, specifically focusing on the Clean Development Mechanism (CDM) and voluntary offset programs. It identifies critical uncertainties in estimating biomass fuel savings, monitoring stove usage, and determining the fraction of non-renewable biomass used. The brief argues that current methodologies often rely on unscientific workarounds, such as using fossil fuel emission factors, and fail to account for significant non-CO2 climate impacts like black carbon.

The Arctic Resilience Interim Report 2013 examines the interdependence of human societies and ecosystems in the Arctic, arguing that a resilience framework is essential for managing rapid, interacting changes. It highlights that while climate change is a key driver, social, political, and economic factors also profoundly impact the region's adaptive capacity. The report warns that abrupt environmental changes risk crossing thresholds with global consequences, such as sea ice loss and permafrost thaw. It further notes that past policy decisions have often eroded traditional indigenous safeguards of resilience, necessitating flexible, participatory governance to manage future uncertainties and conflicting priorities.

The Clean Air Task Force calls on the EPA to finalize carbon dioxide performance standards for new fossil fuel power plants and to initiate regulations for existing power plants and methane emissions from oil and gas operations, noting that existing power plants account for over 40 percent of US carbon dioxide emissions.

The global atmosphere is at a critical stage, with climate change identified as the most pressing issue. While successful international cooperation has phased out ozone-depleting substances and lead in petrol, progress on particulate matter and tropospheric ozone is mixed, particularly in Africa, Asia, and Latin America. Despite the availability of low-carbon technologies, greenhouse gas concentrations continue to rise, leaving a gap of several billion tonnes of CO2 equivalent between current pledges and the targets needed to limit global warming to 2°C. The document advocates for an integrated approach to atmospheric protection and the use of short-lived climate forcers as a complementary strategy to CO2 reduction.

The Clean Air Task Force (CATF) argues that the EPA's final New Source Performance Standards for the oil and gas industry must require 'green completions' to capture methane and volatile organic compounds (VOCs). The memo asserts that methane from US oil and gas operations is 25 times more potent than carbon dioxide over 100 years and contributes to global warming as much as 16% of all CO2 from US coal-fired power plants. CATF rejects industry claims that green completions are too costly or that flaring is a sufficient alternative, noting that such technologies are already used in states like Colorado and Wyoming.

The research evaluates 14 emission control measures for black carbon and methane to determine their impact on air quality and health by 2030. The study finds that full implementation could significantly reduce global surface concentrations of PM2.5 and ozone, avoiding millions of premature deaths annually, with the vast majority of these benefits occurring in Asia.

The Obama administration's FY 2013 budget proposal emphasizes an "all of the above" energy strategy, prioritizing renewable energy, energy efficiency, and infrastructure. Key funding increases are directed toward the Department of Energy's Office of Energy Efficiency and Renewable Energy, building technology research, and high-speed rail. The proposal also calls for the elimination of $4 billion in fossil fuel subsidies and a significant investment in surface transportation, funded by savings from reduced overseas military operations.

The authors identified 14 emission control measures targeting methane and black carbon that could reduce projected global mean warming by approximately 0.5°C by 2050. These measures are estimated to prevent 0.7 to 4.7 million premature deaths annually from outdoor air pollution and increase annual crop yields by 30 to 135 million metric tons from 2030 onwards. The economic benefits of methane reductions (USD 700 to USD 5,000 per metric ton) significantly exceed their marginal abatement costs (under USD 250). Combining these short-term pollutant controls with carbon dioxide reduction measures substantially lowers the risk of exceeding the 2°C warming threshold.

The document distinguishes between dry gas (primarily methane) and wet gas (methane mixed with marketable higher hydrocarbons like ethane, propane, and butane). It identifies gaseous wastes including hydrogen sulfide, sulfur dioxide, methane, and carbon dioxide. It further details liquid wastes, specifically produced water, which can contain carcinogenic chemicals, salts, and naturally occurring radioactive elements such as radium and uranium, noting that many wastewater treatment plants lack the capacity to remove these radioactive chemicals to meet federal drinking water standards.

A coalition of environmental organizations argues that the EPA's proposed rules for the oil and gas industry are insufficient. They demand the direct regulation of methane, the inclusion of existing sources, the elimination of exemptions for certain wells, and the regulation of hydrogen sulfide and particulate matter. The coalition also calls for more stringent toxic air pollutant limits and a more comprehensive health risk assessment for vulnerable populations.

The document highlights the rapid loss of Arctic sea ice and the resulting pressure to exploit undiscovered oil and gas reserves, warning that such activities create a feedback loop of increased emissions and further melting. It emphasizes the risks of Greenland Ice Sheet melting and shifting global weather patterns, while calling for a 'zero emissions Arctic campaign' to enforce the safest, zero-emitting practices for drilling and shipping.

The document argues that large-scale commercial agriculture and timber enterprises, rather than subsistence farming, are the leading drivers of tropical deforestation. It highlights the role of cattle ranching in the Amazon, palm oil plantations in Southeast Asia, and the global demand for timber and paper. The text emphasizes that tropical deforestation accounts for approximately 15 percent of global warming pollution due to the release of carbon stored in trees. It cites the Brazilian soybean moratorium as a successful example of how industry can grow without further forest clearing through societal pressure and improved land-use practices.

The Resources and Energy Analysis Programme (REAP) is an environmental analysis tool that uses an environmentally extended input-output model to assess the global environmental impact of consumption at national, regional, and local levels. It tracks greenhouse gases, ecological footprints, and energy sources across the entire life cycle of products and services, including imports. The tool includes a scenario function to model the effects of political decisions, population changes, and shifts in consumption or transport habits. Originally developed in the UK in 2006, a Swedish version was introduced in April 2011.

The report analyzes how the Canadian agricultural sector can contribute to greenhouse gas reductions and the economic implications of emerging climate policies. It highlights the potential for carbon sequestration in soils and the role of bioenergy, while discussing the complexities of implementing a national cap-and-trade system. Key concerns include the integrity of agricultural offsets, the risk of carbon reversal, and the impact of international trade rules and U.S. policy alignment on Canadian competitiveness.

The document advocates for targeting black carbon—a potent short-lived climate forcer—as a 'no regrets' strategy to slow near-term global warming and reduce premature deaths. It identifies diesel engines, cook stoves, and agricultural burning as primary controllable sources and proposes specific regulatory and financial mechanisms, such as diesel particulate filters and clean stove deployment, to address them.
