The Canadian Climate Institute's research indicates that climate change acts as a continuous drag on Canada's GDP, with cumulative losses estimated at $25 billion by 2025 and potentially up to $103 billion by 2055. The study highlights that low-income households are disproportionately affected and that proactive adaptation can save $13-$15 for every dollar spent, potentially cutting climate costs in half.

The Inflation Reduction Act (IRA) of 2022 represents the largest congressional action to date on climate change, allocating nearly $370 billion toward disadvantaged communities and clean energy. It introduces technology-neutral tax credits starting in 2025, a 10-year runway for energy incentives, and significant funding for domestic manufacturing of solar, wind, and batteries. Rhodium Group modeling suggests the IRA could increase U.S. greenhouse gas reductions to 31%-44% by 2030, potentially meeting the U.S. nationally determined contribution when combined with other agency and local actions. The law also establishes the $27 billion Greenhouse Gas Reduction Fund and provides incentives for electric vehicle adoption, though domestic content requirements may affect the scale of EV growth.

Between October 2021 and September 2022, wind and solar energy became the primary source of electricity in Chile, accounting for 27.5% of generation and surpassing coal at 26.5%. This shift follows a period of rapid growth where wind and solar generation doubled between 2018 and 2021. Since 2016, these renewable sources have fully met the growth in electricity demand, contributing to a 6% reduction in annual CO2 emissions between 2016 and 2021 despite an 11% increase in demand. The report highlights Chile's progress toward its goals of 80% renewable electricity by 2030 and a zero-emissions grid by 2050, noting the closure of 8 coal plants as part of a broader decarbonization plan.

The report assesses gender dynamics and barriers for climate entrepreneurs and support organizations in Latin America and West Africa, specifically focusing on Mexico, Côte d'Ivoire, and Senegal. It identifies systemic gaps in education, agriculture, and energy, and provides recommendations for the project's Executing Entities to increase women's participation in climate innovation.

The research demonstrates that site-specific CNN models can effectively detect retrogressive thaw slumps (RTS) using Sentinel-2 satellite data, achieving precision, recall, and F1 values above 0.8. While this approach enables the creation of time series data to approximate greenhouse gas emissions from rapid permafrost thaw, current results show no clear trends due to the 10 m resolution of the satellite data and a lack of diverse validated training data.

The report finds that the world's largest private companies significantly lag behind their publicly-listed counterparts in setting net zero targets and publishing implementation plans. While 69% of the top 100 public companies have net zero targets, only 32% of the top 100 private companies do. Furthermore, only 13% of private companies with targets have published a plan to achieve them, compared to 73% of public companies. The analysis highlights a 'blind spot' in climate accountability, particularly in high-emitting sectors like fossil fuels, where none of the investigated private firms have pledged net zero. The authors warn of 'fossil-spinning,' where public companies divest carbon-intensive assets to less-regulated private firms, and call for mandatory climate disclosure for large private entities to ensure whole-economy decarbonisation.

The author contends that reducing food loss and waste is a non-contentious solution to climate change and biodiversity loss, yet it remains under-adopted by governments. While some countries have set targets aligned with SDG 12.3, only 38 nations have included food loss and waste in their Nationally Determined Contributions (NDC). The text highlights that agriculture drives 70% of terrestrial biodiversity loss and 30% of greenhouse gas emissions, with rotting food in landfills serving as the third largest cause of methane emissions.

The author uses recent heatwaves and wildfires in Europe to illustrate how climate change exacerbates air pollution and health issues. The text details a feedback loop where petrochemical production leads to plastic pollution, which in turn releases methane and ethylene, harms soil carbon absorption, and disrupts marine food production. It concludes by highlighting the need for holistic legislation, citing the European Union's decarbonization strategy, a proposed UN global treaty on plastic waste, and updates to the Canadian Environmental Protection Act.

The U.S. has seen a steady increase in the frequency and cost of billion-dollar weather and climate disasters since 1980. In 2022, by September 30, the country had already experienced 15 such events totaling $29.3 billion in losses, exceeding the historical annual average of seven. The time between these disasters has shrunk from 82 days in the 1980s to an average of 18 days between 2017 and 2021, reducing the time available for recovery and preparation. While hurricanes are the most costly event type, the overall trend of increasing extremes is linked to human-caused greenhouse gas emissions, with projections suggesting further intensity without rapid emissions cuts.

The study assesses decarbonisation pathways for Ulaanbaatar's heating sector, finding that solar assisted ground source heat pumps (SAGSHP) are more cost-effective and less electricity-intensive than full electrification. While SAGSHP increases fixed costs by 30%, it reduces total costs by 9% due to lower electricity demand and reduced requirements for power capacity and grid expansion. The authors argue that reducing the burden on the power sector is essential to decouple heat and power supply and facilitate the penetration of renewables.

Projected emissions for the analysed major economies under current policies (36.2-41.8 GtCO2e by 2030) remain far above the 43% reduction from 2019 levels required by the Paris Agreement. While average per capita emissions are projected to decrease slightly from 9.6 tCO2e in 2015 to approximately 8.8-8.9 tCO2e by 2030, significant disparities exist, with emissions per capita expected to more than double in Türkiye and Viet Nam while halving in Australia, Canada, the United States, and the United Kingdom. Only eleven countries are currently on track to meet their latest NDC targets, with Brazil and Indonesia moving off track due to increased land-use emission projections.

The Institute for Policy Integrity asserts that the Bureau of Ocean Energy Management (BOEM) is incorrectly relying on a 2009 D.C. Circuit case, Center for Biological Diversity v. Department of the Interior (CBD), to claim it cannot consider downstream greenhouse gas emissions in its 2023–2028 leasing program. The brief argues that while CBD established that the Outer Continental Shelf Lands Act (OCSLA) does not require such consideration, it does not prohibit it, and that considering these effects aligns with OCSLA's text, legislative history, and regulatory history.

The Canadian Climate Institute and Net-Zero Advisory Body advocate for a federal emissions cap on the oil and gas sector, noting that emissions in this sector rose by nearly 20% between 2005 and 2019. They argue that a cap is necessary because current policies are insufficient and that failure to act risks 'locking-in' emissions through high-carbon projects. The authors propose three design priorities: ensuring absolute emissions reductions rather than just intensity improvements, maintaining a focus on low-cost methane reductions, and using market-based instruments to prevent emissions 'leakage' to other jurisdictions.

The Canadian Association of Physicians for the Environment (CAPE) urges the Government of Canada to adopt a 'planetary health' framework in its federal budget, arguing that climate change is the most significant global health threat of the 21st century. Key recommendations include reducing greenhouse gas emissions by 140% below 2005 levels by 2030, phasing out fossil fuel subsidies by 2023, and redirecting public finance from Export Development Canada (EDC) away from fossil fuels. CAPE also advocates for a 'wellbeing economy' that defines success beyond GDP, increased funding for the National Adaptation Strategy, and an additional $200 million for the Chemicals Management Plan to protect vulnerable populations from toxic pollution.

The report details how the global production of nitrogen fertilizers has grown nearly ninefold since 1961, creating a systemic dependency on fossil gas. It argues that the agrochemical industry is collaborating with oil and gas companies to 'launder' fossil fuels through the promotion of blue hydrogen and blue ammonia paired with carbon capture and storage (CCS). The document asserts that these technologies are technically and economically infeasible for most uses and serve as a distraction to delay the phaseout of fossil fuels and industrial agriculture. It further highlights the environmental impacts of these chemicals, including the crossing of planetary boundaries related to nitrogen and phosphorus flows and chemical pollution.

The report applies the AIIB-Amundi Climate Change Investment Framework (CCIF) to evaluate climate-related financial risks and opportunities across sectors, companies, and debt issuers. The analysis reveals a strong focus on climate mitigation and greenhouse gas measurement, but a significant deficiency in climate adaptation planning and implementation. Notably, no analyzed company performed well across all three CCIF objectives: mitigation, adaptation, and financial contribution.

The UN Human Rights Committee ruled that Australia violated the rights to family, home, and culture of Torres Strait Islanders due to inadequate climate adaptation. The decision establishes a precedent for state responsibility for climate-related 'loss and damage' and mandates that Australia provide compensation and secure the communities' continued existence on their islands.

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.

Low-temperature industrial heat (up to 165C) accounts for approximately 35 percent of U.S. industrial process heat demand and produced 171 million metric tons of CO2 in 2021. Industrial heat pumps are identified as the most efficient and cost-effective zero-carbon solution for this range, outperforming alternatives like electrolytic hydrogen, bioenergy, and carbon capture and sequestration. Modeling suggests that a full transition to heat pumps by 2050 would reduce industry GHG emissions by 284 MMT (16 percent) relative to a business-as-usual case and prevent over 3,000 premature deaths by 2050. Economically, this shift could increase U.S. GDP by over $42 billion in 2030 and create 275,000 jobs in 2030. While heat pumps have higher capital costs than natural gas technologies, the gap is small and likely narrowing due to rising natural gas prices and falling electricity costs. The report recommends federal financial support via the DOE's AMMTO and IEDO offices, as well as the implementation of technology-neutral energy efficiency and GHG emission standards.

The report analyzes the IRA's transportation incentives, including tax credits for new and used EVs, commercial vehicle credits, and charging infrastructure support. Through three modeling scenarios (Low, Moderate, High), it estimates that the IRA can increase passenger EV sales shares to 34% (Moderate) or 39% (High) by 2030 compared to a 29% business-as-usual baseline. It highlights that while commercial and light-duty truck adoption will see significant boosts, passenger EV adoption may be limited in the near term by stringent eligibility requirements regarding North American assembly and sourcing from 'entities of concern'. The authors argue that the IRA is a foundational step but insufficient alone to meet 1.5°C climate goals, recommending complementary EPA tailpipe standards, state-level clean vehicle mandates, and strategic electric grid investments.
