The report details how the climate crisis is accelerating in Arizona, leading to increased drought, extreme heat, and flooding. It quantifies specific impacts—such as a 71% decline in Lake Mead's volume since 2000 and nearly 500 heat-related deaths in Maricopa County during the summer of 2023—and outlines the extensive infrastructure, public health, and water management costs required for adaptation.

The report estimates that the total annual cost of cleaning packaging litter in Spain for 2019 ranged from €496 million to €744 million. This includes street cleaning costs between €477 million and €603 million, and beach cleaning costs between €21 million and €141 million. The analysis uses a hybrid weight-and-volume approach to attribute costs, noting that beverage containers represent a significant portion of the expense, particularly in tourist-heavy areas.

The report identifies that 76% of Sidhi district's land area (over 363,000 hectares) has potential for landscape restoration through eight specific tree-based interventions. These include assisted natural regeneration, agri-horti-forestry (wadi), and trees on boundaries. Implementation could generate 3.75 million person-days of wage employment, resulting in INR 710 million in income, and sequester 7 million metric tons of carbon over 10–20 years. However, significant barriers exist, including insecure land tenure, poor market access, and a lack of technical knowledge. The authors recommend establishing 'accelerators' in policy, knowledge, technology, and business to coordinate stakeholders and scale restoration efforts.

The research note analyzes four implementation scenarios for the DOE's Grid Resilience Notice of Proposed Rulemaking (NOPR), which would compensate coal and nuclear plants for costs not recovered in wholesale markets. The analysis finds that annual customer costs could range from $311 million to $10.6 billion, with a high concentration of benefits accruing to a small number of companies, particularly in the PJM region.

Rooftop solar costs in the US have nearly halved since 2007, with projections suggesting that by 2017, more than half of US states could have rooftop solar as cheap as grid electricity without state or local incentives. The number of US homes with rooftop solar grew from 30,000 in 2006 to nearly 400,000 by 2013, with future projections ranging from 1 million by 2020 (EIA) to nearly 4 million (DOE) depending on cost reductions.

The report analyzes the cost gap between U.S. and German residential solar installations, finding that U.S. installation labor costs are significantly higher due to non-value-add activities, complex racking processes, and regulatory requirements. Through a 'time and motion' study of 26 sites, the authors identify opportunities to reduce costs by adopting one-day installations, simplifying racking bases, and innovating AC electrical circuits. The report argues that by removing non-value-add activities, U.S. installers could reduce soft costs by 30% and lower total system costs to $4.43/W.

The report argues that while solar PV module costs have declined aggressively, balance of system (BoS) costs—which account for about half of total installed costs—remain a significant barrier to adoption. Through a design charrette with industry experts, the report proposes a 'systems approach' focusing on physical design, business processes, and industry scaling to reduce BoS costs to $0.60–0.90/watt. Key recommendations include optimizing structural designs to reduce wind forces, rethinking electrical architectures through high-voltage aggregation and module-integrated electronics, streamlining permitting and interconnection processes to reduce project 'dropouts', and adopting high-volume lean manufacturing and component standardization.

The document details CATF's costing approach for CCS retrofits, which utilizes a standalone gas-fired auxiliary boiler for steam to avoid coal plant heat rate penalties, contrasting this with the IPM platform v6's integrated approach. It provides specific capital and operational cost data for 200 MW and 400 MW coal retrofits, as well as NGCC retrofits, noting that while IPM costs favor very large plants through economies of scale, the CATF approach is more favorable for 400 MW units.

The document asserts that CCS is essential to avoid a 2-degree Celsius temperature rise, as it is the only large-scale abatement option for many industrial sources. It highlights that the IEA projects a need for 6,000 million tonnes of CO2 reduction via CCS by 2050. The text argues that CCS is cost-competitive, especially when paired with enhanced oil recovery (EOR), and can be more economical than intermittent renewables when accounting for system balancing and transmission costs.

The Clean Air Task Force (CATF) analysis finds that optimistic forecasts of clean hydrogen costs falling below $1/kg are unrealistic because they overemphasize electrolyzer capital cost reductions while ignoring the dominant impact of electricity prices. Electricity costs account for 50%–75% of the total production cost. Even with projected 2030 improvements in PEM electrolyzer efficiency and capital costs, the authors conclude that average production costs will likely remain above $3/kg (Real 2022 USD) due to the lack of realistic access to clean firm electricity below $40/MWh. The paper recommends that policymakers prioritize clean hydrogen for sectors lacking other viable decarbonization alternatives, such as steel manufacturing and chemical refining, and focus on decarbonizing the power grid to enable scale-up.

The research identifies 656 industrial facilities and 174 ethanol plants in the contiguous U.S. as primary opportunities for point-source carbon capture. It focuses exclusively on process emissions, excluding indirect emissions from the electrical grid and stationary combustion. The study employs a technology-agnostic cost model to estimate the cost of CO2 avoided, incorporating capture, compression, transport (via trucking or pipeline), and injection costs. Key sectors analyzed include cement, bioethanol, refining, hydrogen, and ammonia production, with a particular emphasis on the proximity of these facilities to sedimentary basins and existing CO2 pipelines to determine eligibility for the federal 45Q tax credit.

The Carol Avenue Apartments in Boston are undergoing a deep energy retrofit scheduled for completion in late 2024. The project focuses on transitioning a 33-unit, 1910-era property from fossil fuel-based systems to a fully electric infrastructure. By combining interior wall insulation, roof upgrades, and the installation of a Variable Refrigerant Flow (VRF) system, the property is estimated to reduce energy use by 55 percent. The addition of 65.3 kW of rooftop solar PV is projected to further increase total energy reduction to 64 percent and reduce greenhouse gas emissions by 41 percent.

The Battery Balance of System Charrette report identifies critical barriers to the scaling of behind-the-meter (BTM) energy storage in the U.S., specifically focusing on high non-cell costs, lack of standardization, and limited monetization opportunities. The document outlines a framework for reducing 'balance of system' (BBoS) costs through hardware standardization, streamlined interconnection and permitting, and the creation of new distribution-level markets for aggregated storage services.

The report analyzes electricity supply technologies for Nigerian health facilities, recommending standalone solar PV systems of 5-10kWp for Type 2 PHCs to meet a daily energy demand of 36kWh. It estimates an average installed cost of $6/Wp and calculates a total requirement of $525 million to power 10,000 PHCs over 15 years.

The ACEA Agreement is a voluntary pact between the European automobile manufacturers association and the European Commission to limit fleet average CO2 emissions to 140 gCO2/km by 2008. The author contends that the failure to disclose individual company commitments and performance data prevents investors from understanding the specific financial and competitive implications for Original Equipment Manufacturers (OEMs). A cost analysis of two scenarios—corporate average and uniform percent improvement—reveals significant variability in potential cost exposures for companies such as BMW, PSA Peugeot Citröen, Fiat, and DaimlerChrysler, suggesting that investors face unforeseen risks due to the absence of disclosed CO2 reduction strategies in 2003 annual reports, with BMW being the only exception.
