The U.S. oil and gas sector exhibits extreme variability in methane emissions, with some small producers and specific large companies contributing disproportionately to totals. The author argues that the EPA must implement a regulatory floor mandating best practices to reduce leaks and flaring, noting that existing technology could reduce sector methane emissions by 65% at little to no cost.

The report analyzes 2019 emissions data for U.S. onshore oil and gas production, finding that emissions are highly concentrated among a small number of producers and basins. It highlights significant variance in emissions intensity across companies and identifies pneumatic controllers and fuel combustion equipment as primary sources of methane and CO2 emissions, respectively. The analysis also notes that official reported data likely underestimate actual emissions due to the omission of high-emitting abnormal process conditions and facilities below reporting thresholds.

The document outlines the specific points of methane and CO2 leakage and combustion within the oil and gas industry. It argues that reducing these emissions is critical for meeting the 1.5 degree warming target, noting that methane is 80x more damaging than CO2 in the short term and that existing technologies can reduce these emissions at low cost. The supply chain is broken down into production and processing (onshore and offshore), transmission and storage, and distribution to end users.

A coalition of NGOs issued a statement following a U.S. District Court ruling that granted a preliminary injunction against the delay of the Bureau of Land Management's (BLM) methane waste rule. The court found that the BLM failed to follow legal requirements for agency rulemaking, relying on "opinions untethered to evidence" rather than reasoned analysis. The statement highlights that the 2016 rule requires oil and gas companies to reduce methane venting and flaring and perform leak detection and repair on federal public lands. The NGOs argue that allowing methane waste results in significant financial losses for taxpayers, public health risks from toxic pollutants like benzene, and increased climate emissions due to methane's potency as a greenhouse gas.

Nigeria faces a severe energy crisis with 60-70% of its population lacking regular electricity access and an average output of 5,000 MW against an installed capacity of 12,522 MW. The report identifies critical bottlenecks including a non-cost-reflective tariff regime, a N1 trillion revenue shortfall as of December 2016, and significant gas flaring despite the country ranking 9th globally in natural gas reserves. While hydropower provided approximately 32% of supply in 2015, other renewables like solar and wind remain underdeveloped. The author recommends the total deregulation of the gas sector, universal metering to close a gap of 4.09 million customers, and the implementation of the renewable energy masterplan to achieve a 10% renewable energy contribution by 2025.

The briefing advocates for a binding UN treaty to end the impunity of transnational corporations (TNCs) in Africa. It details systemic environmental degradation and human rights abuses by companies like Shell in Nigeria, Vale in Mozambique, and ArcelorMittal in South Africa, arguing that national legal systems are often insufficient to provide justice and reparations.

This report by Friends of the Earth International and Environmental Rights Action/Friends of the Earth Nigeria examines the failure of the Nigerian judicial system to hold transnational oil corporations, specifically Shell, accountable for environmental degradation and human rights violations in the Niger Delta. The authors argue that systemic barriers in national courts—including high costs, strict standing requirements, and corporate stalling tactics—necessitate the establishment of a World Environmental Court with international jurisdiction to ensure environmental justice.

The report examines the catastrophic environmental and human rights impacts of transnational oil companies, specifically Shell, in Nigeria's Niger Delta. It details the persistence of gas flaring and oil spills, the resulting destruction of rural livelihoods, and the systemic barriers—such as high legal costs, burden of proof, and judicial delays—that prevent victims from accessing justice in Nigerian courts. Through case studies, it demonstrates how corporations use legal stalling and jurisdictional challenges to evade accountability, concluding that a legally binding global treaty and an international environmental court are necessary to protect human rights and the environment.

Earthjustice supports the BLM's proposed methane rule, which covers both new and existing equipment and aims to reduce flaring and leaks. The organization argues that the rule is essential for climate mitigation, as methane is 86 times more powerful than carbon dioxide, and could capture up to $800 million in taxpayer revenue over a decade. However, Earthjustice urges the BLM to close loopholes regarding leak inspections and flaring allowances to ensure the rule's effectiveness.

The Clean Air Task Force views the EPA's proposed methane standards for new and modified oil and gas sources as a positive first step but argues they are insufficient to meet national greenhouse gas reduction targets. While praising the direct regulation of methane under the Clean Air Act and the implementation of leak detection and repair (LDAR) requirements, CATF recommends mandating controls for omitted equipment like liquids unloading operations and increasing LDAR inspection frequency. Crucially, the document highlights that the proposal fails to address existing sources, which are projected to account for 90 percent of methane emissions by 2018.

The report identifies and assesses nine technologies to reduce the flaring of associated gas in US tight oil fields, concluding that Natural Gas Liquid (NGL) recovery, Compressed Natural Gas (CNG) trucking, and Gas-to-Power (for local loads) are the most mature and scalable options. It highlights that flaring in the Bakken and Eagle Ford basins reached approximately 125 billion cubic feet per year by 2013. The analysis emphasizes that while technical solutions exist, robust regulations are necessary to eliminate routine flaring. A case study on Alaska's Shublik formation suggests that while the region has high potential, its remoteness and harsh climate necessitate early infrastructure planning to avoid future flaring.

The Arctic is warming at almost twice the global average rate, a phenomenon known as Arctic amplification. While long-term climate stability requires reducing carbon dioxide, the author argues that targeting short-lived climate pollutants (SLCPs) like black carbon (BC) and methane can provide immediate mitigation benefits. The paper specifically focuses on the shipping and oil and gas sectors, which are expected to grow as sea ice retreats. It recommends a ban on heavy fuel oil (HFO) for shipping to reduce BC and marine risks, and the creation of a best-practices dialogue via the Arctic Economic Council to limit methane releases and flaring in oil production. The author emphasizes that coordinated infrastructure planning is essential to make these cleaner practices viable in the harsh Arctic environment.

The document argues that flaring of associated gas in the Little Missouri National Grassland (LMNG) is unnecessary because CNG trucking is a profitable alternative for a majority of flaring wells. In January 2015, approximately 30% of gas produced within the LMNG was flared. Analysis shows that 61% of wells flaring gas from the Federal mineral estate in and around the LMNG could economically use CNG trucking, which could have captured 83% of the gas flared from those specific wells. If all wells within the LMNG boundaries are considered, 89% of flared gas could be trucked. The author contends that oil producers flare for convenience to prioritize oil production and urges the Bureau of Land Management (BLM) and state regulators to phase out flaring.

The document evaluates technical and commercial viability for several associated gas utilization technologies in US tight oil fields. It identifies gas gathering, CNG trucking, NGL recovery, gas-to-power, and Mini-GTL MT as technologies that pass initial screening, while gas reinjection, Mini-LNG, Mini-GTL FT, and ammonia production are rejected due to scale, maturity, or economic constraints. The report provides detailed technical specifications, cost models, and case studies for these options, specifically focusing on the Bakken region of North Dakota.

Tight oil, also known as shale oil, is extracted from impermeable rock using hydraulic fracturing, a process that is more energy-intensive and polluting than conventional drilling. In the United States, tight oil's share of domestic production rose from 23 percent in 2011 to 45 percent in 2013. Key environmental concerns include flaring of associated natural gas, fugitive methane emissions, and pollution of water, air, and noise. The document argues that transitioning to cleaner transportation technologies and improving extraction infrastructure can reduce the reliance on and emissions from tight oil.

The report identifies the U.S. oil and gas industry as the largest industrial source of methane and argues that the EPA should issue nationwide standards under the Clean Air Act to target the sector's top emitting sources. The authors propose three primary categories of intervention: regular leak detection and repair (LDAR) programs, the replacement of outdated compressors and pneumatic equipment, and the capture of gas from oil and gas wells. These measures are estimated to reduce annual methane emissions by 3.2 to 3.7 million metric tons, a reduction of 42% to 48% of the sector's total. The report emphasizes that direct methane standards would be significantly more effective than regulating volatile organic compounds (VOCs) or relying on voluntary programs. The estimated cost of these measures is low, ranging from $8 to $18 per metric ton of carbon dioxide equivalent, and would represent less than 1% of the industry's sales revenue.

The report profiles ten U.S. cities where residents live in close proximity to petroleum refineries, documenting systemic exposure to toxic air pollutants, high rates of cancer and asthma, and frequent industrial accidents. It highlights a pattern of 'significant violation' of the Clean Air Act by major refineries and notes that these facilities are often located in low-income and minority neighborhoods. The document calls for the EPA to implement more stringent air toxics standards and improved fenceline monitoring to protect public health.

Earthjustice sued the EPA for delaying standards to reduce toxic emissions from oil refineries, leading to a 2015 rule that introduced national fenceline monitoring for benzene and tighter controls on flaring and storage tanks. While the rule is estimated to reduce cancer risks for over one million Americans, Earthjustice and its partners argue the EPA underestimated community harm and failed to require real-time monitoring or prohibit routine flaring.

The document examines Nigeria's energy subsidy regime, focusing on Premium Motor Spirit (PMS), household kerosene (hhK), and electricity. It highlights the immense fiscal burden on the government, with fuel subsidies alone estimated at over ₦2 trillion in 2011. The guide argues that these universal subsidies disproportionately benefit higher-income earners and are plagued by systemic corruption, such as inflated import claims and the diversion of kerosene to black markets. It also notes that under-pricing of energy has stifled investment in refining and power infrastructure, leading to high reliance on private generators and significant gas flaring. The document outlines the government's transition toward cost-reflective electricity tariffs via the Multi-Year Tariff Order (MYTO) and the attempted removal of gasoline subsidies through the SURE-P program, while providing international lessons on gradual price liberalization and targeted social compensation.

The document highlights the climate risks associated with increased oil and gas production in the Arctic, specifically the emissions of methane and black carbon. It argues that the Arctic is uniquely vulnerable, with temperatures rising at twice the global average, and that the potential for an 'oil and gas rush' could exacerbate this. The authors propose a series of technical and policy interventions to mitigate these impacts, including the elimination of venting, the use of vapor recovery units, the adoption of ultra low sulfur diesel, and the establishment of standardized monitoring and reporting protocols.
