The assessment finds that while a traditional benefit-cost ratio (BCR) would render the Bandung BRT project non-investment-worthy at 0.27, a sustainable BCR (S-BCR) that includes wider societal benefits results in a ratio of 6.67. The project is projected to generate a cumulative discounted net benefit of USD 2.02 billion between 2022 and 2050, primarily driven by time savings for commuters. Key environmental and social gains include the reduction of at least 1.2 million tonnes of CO2 emissions and the avoidance of 205 fatalities from traffic accidents.

The June 2021 heatwave in British Columbia was the deadliest disaster in the province's history, resulting in 619 heat-related deaths. The report estimates the economic value of these lost lives at 5.5 billion CAD using the value of a statistical life. Key vulnerabilities identified include a lack of mechanical cooling in residential and public buildings, inadequate urban canopy, and institutional failures in emergency coordination and early warning systems. Economic impacts extended to agriculture, where producers lost at least 25 million CAD in revenue, and the labor market, with significant productivity losses. Future projections suggest that without adaptation, heat-related hospitalizations could reach 6,000 per year by 2030, and annual heat-related deaths could average 1,370 by 2030. The report recommends prioritizing mechanical cooling, urban greening, updating building codes, and improving the precision and lead time of weather warnings to three days.

The June 2021 heat wave in British Columbia was the deadliest disaster in the province's history, resulting in 619 direct heat-related deaths. The report estimates the societal cost of these lives lost at $5.5 billion using the Value of a Statistical Life (VSL) metric. Beyond mortality, the event caused $12 million in healthcare costs, significant agricultural revenue losses (at least $25 million), and disruptions to electricity and transportation infrastructure. Vulnerabilities were exacerbated by a lack of mechanical cooling in homes, inadequate urban greening, and institutional failures in disaster response and communication. The report argues that without adaptation, heat-related hospitalizations could double by 2030 and annual deaths could average 1,370 by 2030. Key recommendations include updating building codes for mechanical cooling, increasing urban forest canopies, improving weather warning lead times to three days, and implementing independent public reviews of disaster responses.

The report evaluates the restoration of the Mallorquín Swamp in Barranquilla, Colombia, using a sustainable asset valuation (SAVi) approach. It finds that nature-based infrastructure (NBI) provides greater societal value and better climate adaptation benefits at a lower cost than grey infrastructure alternatives, particularly when combined with investments in ecotourism.

The report assesses the escalating risk of catastrophic biological threats driven by the democratization of biotechnology and climate change. It highlights that future pandemics could be orders of magnitude more lethal than COVID-19, whether through natural emergence, laboratory accidents, or deliberate use. The authors argue that current U.S. biodefense spending is insufficient, representing less than 1% of the defense budget. They propose a "10+10 over 10" investment plan—$20 billion annually for ten years—focusing on pathogen-agnostic defensive tools, strengthened international norms, and improved deterrence through preparedness. The report concludes that such investments are highly cost-effective compared to the trillions of dollars in potential economic losses and millions of lives at risk.

The assessment of Coimbatore's proposed Non-Motorized Transport (NMT) network reveals that while traditional benefit-cost ratios suggest the project is not investment-worthy, a sustainable valuation (S-BCR) shows a ratio of 4.75 per USD invested. The project, which involves 300 km of routes to be completed by 2035, is projected to generate a cumulative net benefit of USD 486.1 million between 2022 and 2045, primarily driven by avoided costs from traffic accidents and improved public health.

The SAVi assessment of Coimbatore's NMT plan, which involves 300 km of routes to be implemented by 2035, demonstrates that the project is highly profitable from a societal perspective. While a conventional benefit-cost ratio (BCR) suggests the project is not economically viable (0.47 to 0.50), the sustainable benefit-cost ratio (S-BCR), which includes externalities, ranges from 4.75 to 4.93. The largest individual benefit is the avoided cost of traffic accidents, valued at INR 30,144 million. Other significant gains include health benefits from physical activity and reduced fuel costs, although these are partially offset by the health costs of increased air pollution exposure for cyclists.

The report assesses the economic viability of flood mitigation strategies in Colombia's La Mojana region, comparing grey infrastructure, nature-based infrastructure (NBI), and sustainable agriculture. It finds that all considered interventions are investment-worthy, with the potential to avoid over USD 1.26 billion in damages over 30 years.

The report finds that the IRA will significantly accelerate the adoption of electric vehicles (EVs) and zero-emission vehicles (ZEVs) in the US, potentially exceeding the Biden administration's 2030 targets. However, the authors argue that these incentives alone are insufficient to meet the US Nationally Determined Contribution or the Paris Agreement goals, necessitating additional federal GHG standards and investments in infrastructure and manufacturing.

The report identifies a significant financing gap of USD 10 billion per year needed to achieve sustainable food system transformation in Ethiopia, Malawi, and Nigeria. It argues that current funding is overly skewed toward short-term emergency assistance rather than long-term agricultural development. By investing in on-farm productivity, social protection, and climate-resilient infrastructure, the report projects that undernourishment could drop below 3% and the incomes of 29 million small-scale producers could double by 2030, all while meeting nationally determined contribution goals for greenhouse gas emissions.

Ethiopia is not on track to meet the UN Sustainable Development Goals by 2030, with poverty and hunger projected to remain high due to conflict in Tigray, climate change, and economic shocks. The report argues that a sustainable food system transformation is possible with an additional annual public investment of USD 4.6 billion from 2023 to 2030. This funding would target increasing agricultural productivity, transitioning to healthier diets, and enhancing climate resilience. A significant financing gap exists between short-term emergency food assistance and the long-term investments required for systemic resilience. Key recommendations include prioritizing on-farm interventions, scaling up sustainable livestock intensification to reduce GHG emissions, and integrating nutrition education with social protection programs.

The report evaluates a 2,868-hectare assisted natural regeneration (ANR) project in Sodo Woreda, Ethiopia, finding that it provides direct economic benefits to farmers and delivers climate adaptation and mitigation services. The analysis demonstrates that ANR is an investment-worthy strategy for combating land degradation and enhancing rural resilience, particularly when located upland of cropland to reduce erosion.

The report argues that BEVs are generally not the optimal short-term decarbonization strategy for most Indian vehicle segments due to high costs, a coal-dependent electric grid, and poor cost-effectiveness per ton of CO2 reduced, with the notable exceptions of commercial three-wheelers and low-speed vehicles. It suggests that improving conventional engine efficiency, adopting mild hybrid technology, and increasing ethanol blending offer more viable near-term emissions reductions.

The report evaluates 10 water retention projects in Manitoba's Seine Rat Roseau Watershed District, finding that such projects generally provide positive economic returns, particularly for livestock producers. While upfront construction costs are the primary expense, benefits include flood and drought protection, improved water quality, and operational efficiencies. A cost-benefit analysis indicates an average benefit-cost ratio of 3.16 for livestock producers over a 20-year period, though crop-only operations showed lower returns due to high initial costs and fewer on-farm co-benefits.

Australia could reduce its annual methane emissions by 18% by 2030 by focusing on coal mine methane (CMM) mitigation. The report argues that CMM is one of the cheapest and fastest sources of methane to mitigate, costing approximately $270 AUD per tonne of methane, which is four times cheaper than agricultural mitigation. Key recommendations include phasing out thermal coal mines by 2030, preventing new coal mine expansions, and implementing technical solutions like ventilation air methane (VAM) capture and extensive drainage. The report also warns that current reporting is likely underestimated, citing the IEA's estimate that 800 thousand tonnes of methane are missing from reported figures.

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.

The Green Climate Fund (GCF) has developed a policy to protect its commitment authority from foreign exchange (FX) volatility, primarily driven by non-USD denominated promissory notes. The proposed strategy prioritizes natural hedging, followed by the use of derivative financial instruments—specifically FX spot, forward, and swap contracts—to lock in the USD value of future encashments. To implement this, the GCF intends to outsource execution to an external third-party provider and establish a USD 50 million collateral reserve. The policy aims to increase funding predictability and reduce the required size of the FX commitment risk buffer.

Malawi is not on track to meet its 2030 Sustainable Development Goals due to climate change, economic shocks, and high poverty. The report argues that an additional annual public investment of USD 543 million is required to end hunger, double smallholder incomes, and transition 14 million people to healthier diets while meeting climate commitments. Key priorities include on-farm investments in irrigation and livestock, nutrition education, and building climate resilience for vulnerable groups, particularly women.

The report demonstrates that Europe can achieve a 94-96% clean power system by 2035 at no extra cost compared to stated policies, provided wind and solar deployment quadruples. This transition would enable wider electrification, potentially halving fossil fuel consumption by 2030 and saving between €530 billion and €1 trillion by 2035. Key requirements include expanding interconnection, deploying electrolysers for green hydrogen, and phasing out coal by 2030 and unabated baseload gas after 2025.

The California Energy Policy Simulator (EPS) 3.3.1 update finds that current policy commitments will leave California's 2030 emissions nearly 20% above the SB 32 target. To address this, Energy Innovation proposes a 'Deeper Decarbonization Scenario' focusing on rapid electrification of vehicles, appliances, and industry, alongside a strengthened clean energy standard. This approach is projected to lower 2030 emissions to 230 MMT of CO2e and generate significant economic and public health benefits, including $60 billion in monetized social benefits by 2050, while reducing reliance on unproven carbon dioxide removal technologies.
