The report highlights that the true lifetime cost of plastic is 8 times higher in low- and middle-income countries (LMICs) than in high-income countries (HICs), primarily due to higher waste mismanagement rates and subsequent marine ecosystem damage. It identifies three structural inequities: the lack of influence LMICs have over global production, their limited waste management capacity, and the absence of accountability mechanisms for producers. To address this, WWF calls for a global treaty with binding rules on production bans, circular design standards, and Extended Producer Responsibility (EPR) schemes.

The report argues that a carbon price exceeding US$ 20 per ton of CO2 captured would make forest restoration more profitable than cattle ranching across most of the Brazilian Amazon. This mechanism could capture 16 Gt CO2 through restoration and avoid 32 Gt CO2 from deforestation over 30 years, totaling 48 Gt CO2. The study uses a dynamic spatial model to show that such payments would generate US$ 320 billion in revenue, preventing the forest from reaching a tipping point and transforming the region from a net carbon emitter to a carbon sink.

The report argues that a carbon price of US$ 20 per ton of CO2 captured would incentivize a shift from cattle ranching to forest restoration in the Brazilian Amazon. This transition could capture 16 Gt of CO2 and avoid 32 Gt of emissions over 30 years, generating US$ 320 billion in revenue. The analysis contrasts this with a historical implicit valuation of US$ 5.76 per ton, which the authors suggest leads toward a critical tipping point of deforestation.

The report critiques the current linear economy and the limitations of the conventional circular economy, proposing instead a 'resource-balanced economy' (RBE) for the SADC region. It argues that the green transition's demand for critical minerals is underestimated and faces thermodynamic and material constraints. To avoid 'financial capture' and poverty traps, the authors advocate for 'anticipatory governance'—a proactive, systems-based approach to policymaking—alongside bioregionalism, re-localisation, and the renegotiation of resource trade agreements to ensure equitable and sustainable development.

The report analyzes two policy scenarios for Pennsylvania's medium- and heavy-duty (M/HD) vehicle fleet: the adoption of California's Advanced Clean Trucks (ACT) rule and a more aggressive '100 x 40 ZEV + Clean Grid' scenario. Both scenarios project significant reductions in greenhouse gas (GHG), nitrogen oxide (NOx), and particulate matter (PM) emissions, leading to substantial public health benefits and net societal gains. While initial costs for fleets are higher, the report finds that ZEVs will reach lifetime cost parity with combustion vehicles as purchase prices fall and fuel/maintenance savings accumulate. The transition is projected to generate positive macroeconomic effects, including net national job gains and increased GDP by 2035, and could potentially lower electricity rates for residential and commercial customers due to increased utility net revenue from EV charging.

The analysis finds that transitioning Maryland's medium- and heavy-duty vehicle fleet to zero-emission vehicles (ZEVs) would yield significant net societal benefits, ranging from $6.6 billion under the ACT rule to over $11.6 billion under the 100 x 40 ZEV scenario by 2050. These benefits are driven by reductions in greenhouse gases, nitrogen oxides, and particulate matter, leading to fewer premature deaths and hospital visits. While ZEVs currently have higher purchase costs, the report projects they will reach lifetime cost parity with combustion vehicles due to lower fuel and maintenance expenses. The transition is expected to have positive macroeconomic effects, including net national job gains and increased GDP, although it requires substantial investment in depot and public charging infrastructure.

The analysis finds that CCS projects in Canadian oil sands are economically viable under current and proposed climate policies, such as carbon pricing and investment tax credits, potentially offering private returns of up to 21%. Consequently, the authors argue that additional public funding beyond what is already announced is unnecessary and could lead to excessive corporate profits. While CCS improves the carbon intensity of oil sands production, it does not eliminate the long-term transition risk associated with declining global oil demand.

Industrial thermal batteries can convert electricity into high-temperature heat (1,500-1,700°C), potentially displacing 75% of U.S. industrial non-feedstock energy demand. The report analyzes two primary deployment modes: 'generation-following' (off-grid renewables) and 'price-hunting' (grid-connected, price-responsive). It finds that these batteries can provide heat at $35 to $62 per MWh, making them competitive with natural gas. The authors recommend financial incentives via the Inflation Reduction Act and reforms to electricity tariffs to reward the grid flexibility these batteries provide.

The report argues that federal investments in clean electricity will lower overall energy expenses for Canadians by 2050, despite modest increases in electricity rates, provided that provinces implement targeted affordability measures for low-income households.

The report argues that a 'New Economy for the Brazilian Amazon' (NEA), characterized by zero deforestation and a robust bioeconomy, would provide the most equitable economic growth for Brazil. By 2050, this transition could increase the regional GDP by BRL 40 billion and create 312,000 additional jobs compared to a reference scenario. The study emphasizes that eliminating deforestation alone is insufficient to meet Paris Agreement targets; it must be coupled with the decarbonization of agriculture, livestock, and the energy matrix. The transition requires an estimated BRL 2.56 trillion in additional investment by 2050, representing 1.8% of Brazil's national GDP per year. Key recommendations include removing fossil fuel subsidies, redirecting rural credit toward low-carbon practices, and scaling a bioeconomy based on traditional indigenous knowledge and standing forests.

The Stockholm Environment Institute argues that full linkage between Washington's carbon market and the California-Quebec (WCI) market currently poses risks to Washington's environmental goals due to misaligned time horizons and differing levels of ambition. Specifically, the authors highlight a large bank of unused allowances in California that could reduce in-state emission reductions and auction revenues in Washington. They recommend that full linkage be contingent on California extending its program beyond 2030 and tightening its 2030 cap. As an interim measure, the authors propose 'restricted linkage'—such as a limit on the import of WCI allowances (e.g., 2-3% of compliance obligations)—to provide cost containment while maintaining environmental integrity and revenue streams for overburdened communities.

The report finds that if all 177 States adopting California's standards implement the Advanced Clean Cars II (ACC II) rule, U.S. emissions could be reduced by 1,310 million metric tons of CO2e by 2050. This adoption would lead to three-quarters of U.S. cars being electric vehicles (EVs) by 2050, creating nearly 300,000 jobs and saving households an average of $238 annually. The analysis emphasizes that while the IRA provides near-term incentives, the ACC II mandate is necessary for long-term electrification goals. Case studies for Maryland, New Jersey, New Mexico, and New York highlight significant state-level benefits, including substantial reductions in asthma attacks and premature deaths, particularly in communities of color.

The report examines the implementation of the Section 45V hydrogen production tax credit from the Inflation Reduction Act. It argues that loose guidance on emissions accounting could lead to significant increases in greenhouse gas emissions and create an industry reliant on subsidies. The authors propose a framework based on three principles: additionality (requiring new clean energy sources), deliverability (requiring local, physically deliverable power), and time-matching (requiring hourly alignment of production and generation). Financial analysis of test sites in Texas, Minnesota, and Houston suggests that projects adhering to these strict standards remain profitable, particularly in regions with high wind and solar resource quality.

RMI's analysis indicates that US states can secure significant federal investment, job growth, and health improvements by ambitiously adopting the Inflation Reduction Act's (IRA) tax credits, rebates, and grants. Under a "Climate Ambitious Scenario," states could see cumulative investments between $1 billion and $130 billion by 2030, with the highest per capita gains expected in states with strong renewable energy potential and industrial activity, such as Wyoming, Montana, and Louisiana.

The report demonstrates that implementing five core policies—clean electricity standards, zero-emission vehicle standards, clean building equipment standards, industrial efficiency and emissions standards, and methane detection and capture standards—can dramatically cut greenhouse gas emissions in Louisiana, Michigan, Minnesota, New Mexico, Pennsylvania, and Wisconsin. Using the Energy Policy Simulator (EPS), the authors find that these policies not only reduce emissions but also drive job growth, increase GDP, and prevent premature deaths by reducing air pollutants. The analysis highlights that while state emissions profiles vary—with Louisiana dominated by industry and New Mexico by methane from oil and gas—these five policies provide a consistent framework for decarbonization.

The report examines the potential for decarbonizing Canada's residential building sector by replacing central air conditioners with heat pumps. It identifies five primary barriers to adoption—lack of familiarity, the infrequent nature of HVAC replacement, short decision windows during emergencies, limited stock, and higher initial costs. The authors model a scenario where all new central air conditioners are replaced by heat pumps from 2025 to 2035, projecting a net benefit of 12.6 billion CAD, including 10.4 billion CAD in energy bill savings and a reduction of 19.6 million tonnes of CO2 equivalent. The document proposes several policy interventions, including national equipment regulations, updated building codes, and upstream incentives for distributors and manufacturers, while highlighting the importance of energy justice for low-income tenants and vulnerable populations.

The document examines the tension between Africa's development goals, specifically Agenda 2063, and the risk of high-carbon growth. It argues that while pursuing traditional fossil-fuel-led development would significantly increase carbon emissions, Africa can leverage its vast reserves of critical minerals and renewable energy potential to achieve a low-carbon transition. The authors emphasize that climate change exacerbates existing instabilities and that current global climate finance architectures are inadequate, often treating adaptation as aid or providing loans that increase debt. The brief recommends a multi-actor approach to African agency and a strategic shift to place climate change at the center of all diplomacy and development to avoid the 'resource curse' and ensure equitable wealth redistribution.

The report argues that while the Inflation Reduction Act (IRA) significantly advances U.S. climate goals, it is insufficient on its own to meet the 2030 NDC. Using the Energy Policy Simulator (EPS), the authors propose a comprehensive set of additional federal, state, and local policies across the electricity, industry, transportation, and building sectors. The electricity sector is identified as the primary driver for 2030 reductions due to its ability to decarbonize faster than sectors limited by slow stock turnover. Proposed measures include a nationwide 80 percent clean electricity standard, stricter tailpipe emissions standards, and the electrification of industrial and building heating. The report estimates that this combined policy pathway would create 2.7 million additional jobs, grow GDP by $700 billion, and avoid 3,900 premature deaths by 2030.

The report identifies a 'carbon-pricing certainty gap' that inhibits private investment in Canada's industrial decarbonization. It proposes three primary recommendations: introducing carbon contracts for difference (CCfDs) to guarantee the carbon-price schedule, preventing carbon-credit oversupply through strengthened federal benchmarks and public registries, and offering policy-contingent loans via the Canada Infrastructure Bank. The authors suggest that a successful CCfD program could accelerate up to 40 Mt of emissions reductions by 2030 with limited contingent liabilities for the government.

The Inflation Reduction Act (IRA) of 2022 provides significant tax credits and financing to lower the cost of clean electricity and facilitate the retirement of fossil fuel infrastructure. Independent modeling suggests the IRA could make 73% to 76% clean electricity the lowest-cost pathway for the U.S. by 2030, potentially reducing electricity sector GHG emissions by 67% to 78% from 2005 levels. However, the report argues that realizing these benefits requires proactive state-level policy, including updated procurement assumptions by Public Utility Commissions, increased clean electricity standards from legislators, and strategic coordination by governors to address transmission and supply-chain constraints.
