The document details the global nickel market, highlighting Indonesia's dominance in production and the shifting demand from stainless steel toward electric vehicle batteries. It outlines the technical processing pathways for Class I and Class II nickel, the geopolitical impact of export bans, and the environmental footprints associated with different mining and refining methods.

The document examines the lifecycle of plastic packaging, highlighting the environmental damage caused by fossil-fuel extraction and the social burdens placed on low- and middle-income countries during production. It details the technical distinctions between recyclable, recycled, biobased, and biodegradable plastics, while noting that additives and multi-material layers often hinder recycling efforts. The paper also addresses health risks associated with endocrine disruptors and microplastics, and the challenges of contaminating recycling streams with compostable plastics like PLA.

The document argues that the market price of fossil fuels fails to account for significant 'hidden costs' or externalities occurring during extraction, transport, and combustion. It details the severe health impacts of coal mining, such as black lung and cardiovascular disease, and the environmental degradation caused by mountaintop removal in Appalachia. The paper also examines the risks of oil and gas drilling, including methane leakage, water contamination from fracking, and catastrophic spills. Finally, it quantifies the economic burden of air pollution and global warming emissions, contrasting these with the lower impacts of renewable energy sources.

The report assesses decarbonisation strategies for refineries across four major regions, focusing on Scope 1, 2, and 3 emissions. It evaluates technologies such as carbon capture, blue and green hydrogen, and the transition to biorefineries (specifically the HEFA process) or clean fuels facilities. Regional analysis shows that while the US and GCC benefit from cheap natural gas for blue hydrogen, Europe is trending toward green hydrogen imports and biorefinery revamps. Singapore's strategy is heavily influenced by its status as a global trading hub and its lack of domestic natural gas or carbon storage resources. The report concludes that energy efficiency projects are generally the most immediate and viable, while large-scale carbon capture and hydrogen transitions require significant policy support and infrastructure development to be economically feasible.

The analysis finds that while gas-fired power plants emit 58% less CO2 at the stack than coal, the lifecycle benefit is reduced to 24% when considering upstream emissions. This benefit varies wildly by production basin; gas from northeast Pennsylvania can significantly reduce GHG impacts, while gas from the Permian basin could potentially worsen them by 20% compared to coal. The report concludes that for natural gas to be compatible with net-zero goals, both aggressive upstream methane abatement and downstream carbon capture and storage (CCS) are required, noting that abated coal with CCS actually shows 37% lower emissions than abated gas with CCS due to the latter's persistent upstream methane and liquefaction emissions.

The analysis examines the complexities of assessing the climate impact of U.S. LNG exports, highlighting that lifecycle emissions vary significantly based on the source basin and the level of upstream and downstream mitigation. Using a case study of power generation in Vietnam, the author demonstrates that switching from coal to U.S. gas could either reduce greenhouse gas impacts by 40% or increase them by 20% depending on methane management. While U.S. EPA regulations and the Methane Emissions Reduction Program are expected to curb emissions, the document asserts that further policies and the application of carbon capture and storage are necessary for gas to remain viable in a climate-constrained world.

The report argues that the plastic lifecycle is a significant and growing driver of climate change, potentially consuming 1013 percent of the remaining carbon budget by 2050. It details emissions from fracking, steam cracking, and incineration, while highlighting the emerging threat of microplastics interfering with the ocean's carbon sink. The authors conclude that only a dramatic reduction in plastic production and a transition to zero-waste systems can mitigate these impacts.

The report details how plastic poses distinct health risks at every stage of its supply chain. It highlights toxic emissions during extraction and refining, the leaching of endocrine disruptors and carcinogens during consumer use, and the release of heavy metals and dioxins during waste incineration. The document emphasizes that microplastics and associated chemicals contaminate the global food chain, water supplies, and human tissues, while noting significant knowledge gaps and a lack of industry transparency regarding chemical compositions.

The report examines the lifecycle emissions of major transportation fuels, finding that while electricity and biofuels are becoming cleaner, oil is becoming more polluting due to the shift toward unconventional sources like tar sands and fracking. It advocates for the 'Half the Oil' plan to reduce U.S. oil use by 50% by 2035 and calls for greater corporate accountability, transparency in emissions reporting, and a shift toward renewable electricity and non-food biofuels.

The document finds that hydrogen fuel cell electric vehicles (FCEVs), such as the Hyundai Tucson Fuel Cell SUV, produce significantly lower lifecycle global warming emissions than their gasoline counterparts. While emissions depend on the hydrogen source—with natural gas being the current primary source—the use of renewable hydrogen can reduce emissions by over 50% compared to gasoline. California is highlighted as a leader in this transition through its Zero Emission Vehicle program and SB 1505, which mandates a minimum of 33% renewable hydrogen content at state-supported stations.

The Clean Air Task Force (CATF) argues that US corn ethanol's lifecycle GHG emissions are significantly higher than EPA estimates. By shifting the analysis period to 2010-2044, CATF finds that corn ethanol emissions are approximately 28% higher than gasoline. The paper further examines scenarios where the shortfall in cellulosic biofuel production is filled by other fuels, finding that allowing sugarcane ethanol imports or additional corn ethanol would substantially increase total CO2 emissions.

The document details how plastic production, refining, waste management, and environmental degradation contribute to global warming, projecting that cumulative emissions could consume 10-13% of the remaining carbon budget by 2050.
