INDIA’S AVIATION OPPORTUNITY: TURNING AGRICULTURAL RESIDUE AND LOW-COST SOLAR INTO COMPETITIVE SUSTAINABLE AVIATION FUEL WITH POWER-AND-BIOMASS-TO-LIQUIDS
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.

Biogas and its role in the energy transition
The document argues that biogas and biomethane should primarily be reserved for hard-to-abate sectors like petrochemical production and industrial heating, as electrification via renewable energy is more cost-effective for power and heat. It highlights that biogas only addresses a minority of agricultural emissions (at most 28.9%) and warns that scaling production to meet targets, such as the EU's 35 bcm goal by 2030, could threaten food security by requiring significant arable land. Additionally, the briefing notes risks from fugitive methane emissions, high reliance on public subsidies, and safety hazards including explosions and toxicity.

The Impacts of Infrastructure Sector Corruption on Conservation
The document argues that infrastructure corruption, particularly 'grand corruption' occurring early in the project lifecycle, leads to oversized or unnecessary projects that cause irreversible ecological damage. It distinguishes between petty corruption, which typically has indirect conservation impacts, and grand corruption, which influences project scope and design for private gain. Using a lifecycle analysis (origination, feasibility/design, contracting/implementation, operation/maintenance, and evaluation/audit), the briefing identifies specific risks such as bribed environmental impact assessments and the circumvention of protections. It proposes anti-corruption strategies based on integrity, transparency, and accountability, recommending risk assessments and a combination of advocacy and direct action to improve conservation outcomes.

Fueling a Clean Transportation Future
The document analyzes the evolution of ethanol use in the U.S., noting that while E10 blends have reduced oil dependence, corn-based ethanol causes significant environmental damage and can spike global food prices. It argues for a shift toward advanced biofuels derived from wastes, agricultural residues, and perennial crops to lower lifecycle emissions and protect biodiversity. The report forecasts that by 2050, emissions from biorefineries, agriculture, and land use can be substantially reduced through technological optimization and smarter crop choices.

High Octane Fuels: Challenges and Opportunities
The document examines the potential for mid-level ethanol blends (E25 to E40) to improve fuel efficiency and reduce greenhouse gas emissions in the U.S. transportation sector. It highlights that a significant portion of the existing vehicle fleet and fuel infrastructure can accommodate these blends with moderate costs. Research indicates that increasing ethanol content can enhance engine performance and that a nationwide E25 blend could reduce transportation GHG intensity by 5 to 9 percent.

Hypercars: A Market-Oriented Approach to Meeting Lifecycle Environmental Goals
The document proposes the "hypercar" concept, which utilizes a recursive "mass decompounding" process to create ultralight vehicles. By combining advanced composites and hybrid-electric drives, the authors argue that cars can achieve significantly higher fuel economy and lower emissions without sacrificing performance or cost. The paper examines the lifecycle benefits of this approach, including reduced embodied energy in manufacturing, lower in-use emissions, and the potential for high-value recycling of polymer composites through processes like low-temperature catalytic pyrolysis.
