This research paper proposes that India can develop a cost-competitive sustainable aviation fuel (SAF) industry using power-and-biomass-to-liquids (PBtL) technology, leveraging low-cost green hydrogen and agricultural residue to reduce crude oil imports and aviation emissions.

India is uniquely positioned to produce cost-competitive sustainable aviation fuel (SAF) using a power-and-biomass-to-liquids (PBtL) pathway. By combining low-cost green hydrogen—enabled by plummeting solar and battery costs—with abundant agricultural residue, India can produce SAF that is more cost-effective and has lower carbon intensity than competing technologies like HEFA, ATJ, BtL, and PtL. Analysis indicates that a 2030 PBtL project could produce SAF at costs 40% lower than recent fossil jet fuel prices, with parity potentially reached in the 2030s. Beyond decarbonization, this approach reduces dependence on crude oil imports (currently 90% of supply) and mitigates severe air pollution caused by open-field residue burning, which is linked to 44,000 to 98,000 premature deaths annually. The brief recommends government support through first-of-a-kind demonstration projects near Delhi, Pune, and Mumbai airports, the use of trade policies to access EU and UK markets, and the implementation of incentives based on the social cost of carbon and avoided health costs from air pollution.

The report argues that India is uniquely positioned to lead in sustainable aviation fuel (SAF) production via the power-and-biomass-to-liquids (PBtL) pathway. By combining world-leading low-cost green hydrogen (driven by cheap solar power) with an abundance of surplus agricultural residue, India can produce SAF at costs significantly lower than global benchmarks. The analysis shows that PBtL is more resource-efficient and has a lower carbon intensity than other pathways like HEFA, ATJ, and BtL. The report projects that PBtL SAF could reach price parity with fossil aviation turbine fuel (ATF) in the 2030s, providing a hedge against crude oil price volatility and reducing air pollution from crop residue burning. It identifies regions around Delhi, Pune, and Mumbai airports as ideal for first-of-a-kind demonstration projects.

The study finds that anthropogenic climate change approximately tripled the probability of the April 2026 heatwave in northwestern India and Pakistan, making it about 1°C hotter than it would have been in a preindustrial climate. Analysis indicates that extreme heat is occurring earlier in the season, with the likelihood and intensity of April events increasing more rapidly than those in May. This trend extends the period of dangerous heat exposure for hundreds of millions of people, compounding risks to health, agriculture, and the economy. The report also highlights systemic vulnerabilities, noting that heatwaves are not officially declared disasters in India and Pakistan, which limits access to relief funding.

The document advocates for a transformative approach to climate adaptation that moves beyond infrastructure to include 'communication justice'. It highlights the role of constructive journalism in combating 'climate fatigue' and the potential of AI to improve disaster prediction and information dissemination. The author criticises global agendas, such as those for COP30, for overlooking the role of independent journalism and public engagement. The statement calls for coordinated collaboration between governments, the private sector, and local communities to close digital divides and ensure that the voices of the most vulnerable are integrated into national development plans.

The document evaluates the feasibility of fuel cell electric trucks (FCETs) and hydrogen internal combustion engine (ICE) trucks in India. It finds that while FCETs could be more cost-competitive than diesel trucks in long-haul, heavy-duty applications by 2040, they currently struggle to reach cost parity with battery electric trucks (BETs) due to high hydrogen fuel costs. These costs are driven by production, refueling infrastructure, and an 18% GST. The brief argues that hydrogen trucks are a critical complement to BETs for use cases requiring high payload and minimal downtime. It recommends a coordinated pathway involving capital subsidies, tax rationalization (reducing GST to 5%), and the development of public hydrogen refueling stations (HRS) to unlock the market.

The report analyzes the challenges and opportunities for financing nature-based solutions (NbS) in Indian cities, noting a heavy reliance on public funds and a lack of bankable project pipelines. It maps a wide array of financial and business mechanisms—ranging from green bonds and CSR funds to land value capture—and provides early recommendations to improve the enabling environment, project bankability, and the diversification of funding sources to enhance urban climate resilience.

The document addresses the financing gap for urban Nature-based Solutions (NbS) in India, where investment remains heavily dependent on public funds. It proposes a three-step guidance framework: identifying the enabling policy environment, leveraging financial and business mechanisms, and applying a nine-factor project evaluation framework. The guide maps existing Indian national and sub-national policies—including forestry, water, and infrastructure schemes—that can be leveraged for NbS. It also catalogues various financial instruments (such as municipal bonds, green bonds, and blended finance) and business models (including carbon credits and user-pay systems) to improve project bankability. A repository of nine global and domestic case studies, such as Chennai's municipal bonds for stormwater drainage and Chicago's Tax Increment Financing for green roofs, illustrates replicable approaches for Indian urban contexts.

The document proposes a shift from traditional technology-replacement efficiency to a 'whole-systems' approach. It argues that combining electrification with energy end-use efficiency (reducing the demand for energy services) can reduce overall energy demand by 50-75%. The author provides sector-specific examples: in buildings, through passive design and compact urban development; in mobility, via land-use reforms and smaller, lighter electric vehicles; in freight, through modal shifts to rail and material demand reduction; and in steel, via circularity and material substitution. The brief concludes that achieving the COP28 goal of doubling energy efficiency improvement rates requires engaging a diverse range of stakeholders to trigger social tipping points.

The MigrationRhythms project conducted a face-to-face survey in Hanoi, Karachi, Manila, and Mumbai to investigate the relationship between migration and upward social mobility among the lower-to-middle-middle class. The documentation describes a probability-based sampling method using random walks to identify 500 respondents per city. It details the use of SurveyCTO CAPI software for data collection, the development of a structured questionnaire covering socio-economic status and multi-generational migration histories, and the rigorous data cleaning and anonymization processes required to produce an open-access dataset for publication on Zenodo.

The report discloses the environmental and social management framework for a 50 MW solar power project in Karnataka, India. Classified as Category B, the project has undergone an Environmental and Social Impact Assessment (ESIA) and established an Environmental and Social Management Plan (ESMP) to manage risks related to land leasing, labour, and community health. The project will be governed by the Radiance business-specific ESGMS, which aligns with the Green Growth Equity Fund (GGEF) and Green Climate Fund (GCF) policies.

The report evaluates India's readiness to scale subnational climate finance across four categories: climate policy, budget and finance, climate data, and coordination. It finds that while India has strong national commitments and policies, urban local bodies (ULBs) lack institutional mandates for climate action, suffer from limited fiscal autonomy and poor financial management, and have minimal access to climate-specific data. The analysis highlights a heavy reliance on intergovernmental transfers and a significant gap in private investment and municipal bond issuance. Key recommendations include amending state municipal acts to incorporate climate functions, expanding the scope of Central Finance Commission grants to include climate action, and strengthening the capacity of ULBs to conduct green budgeting and issue municipal bonds.

WRI implemented over 30 nature-based projects in Mumbai, Kochi, and Jaipur, including urban farming and water-body restoration, to combat climate risks like urban flooding and extreme heat. These initiatives, which included a school-based gardening project in Mumbai scaling to 250 schools and an urban farm at Jaipur Central Jail, led to the establishment of India's first national-level forum on urban nature-based solutions to share best practices and scale these approaches across Indian cities.

The document examines what it means to be and become 'middle class' in Mumbai, highlighting the importance of education, salaried employment, and assets like home ownership. It finds that while internal migration to Mumbai is a primary driver of social mobility, international migration is perceived as less essential for improving living standards. The study reveals a complex view of upward mobility that combines hard work, formal education, and social connections.

The document explores how residents of Metro Manila define being and becoming middle class, highlighting a diversity of markers including employment, consumption, and values. It examines the intersection of social mobility and migration, noting that Metro Manila serves as a hub for internal migrants and a transit point for international migration, with remittances and family support networks playing key roles in achieving middle-class status.

Lodha is implementing a systems-leadership approach to decarbonize India's rapidly growing built environment, aiming for carbon neutrality by 2035. Central to this strategy is the Palava project near Mumbai, which serves as a 'smart city learning lab' to test sustainable urban design and energy-efficient construction. Through the Lodha Net Zero Urban Accelerator, the company seeks to scale these learnings and influence industry standards and government policy.

The document analyzes Gogoro's transition from a startup to a global provider of light EV battery swapping. It attributes the company's success to three system-level innovations: the creation of a swappable battery standard adopted by multiple manufacturers, the implementation of new business models such as battery-as-a-service and virtual power plants, and the development of a physical 'swap-and-go' platform. The case study highlights Gogoro's role as a catalyst in Taiwan, where its batteries power 90 percent of electric scooters, and its strategic expansion into markets like India, South Korea, and the Philippines.

The document defines Nature-based Solutions (NbS) as actions to protect, manage, and restore ecosystems to address societal challenges while providing biodiversity and human well-being benefits. It identifies a lack of specific NbS frameworks in South Asia but notes that existing national laws and policies in India, Bangladesh, and Nepal provide a foundation for their mainstreaming. The report categorizes NbS into five IUCN-based approaches: ecosystem restoration, issue-specific ecosystem-related, infrastructure-related, ecosystem-based management, and ecosystem-protection. It details 15 urban case studies, including the Yamuna Biodiversity Park in New Delhi, the restoration of riverine areas in Rohingya camps in Cox's Bazar, and the Green Lumbini Initiative in Nepal, highlighting the role of multidisciplinary partnerships and community engagement in achieving ecological and socio-economic resilience.

The analysis examines how the expansion of built-up areas at the expense of natural heat sinks like green spaces and water bodies increases urban heat risks in major cities across the Critical 9 countries. Using Copernicus Land Monitoring Service data and the IPCC's SSP1-1.9 scenario, the report details specific land-use losses in cities such as Shanghai, Karachi, and Dhaka, linking these changes to increased vulnerability to dangerous heat days (above 35°C) and rising energy demands for active cooling.

The report assesses the gender landscape in India's urban transport and e-mobility sectors to identify barriers for women, such as safety concerns and limited workforce participation. It proposes a Gender Action Plan for a financing platform, focusing on increasing female employment, improving safety infrastructure (like lighting and CCTV), and collecting sex-disaggregated data to mitigate gender-blindness in project design.
