Lexie Bullock is an environmental professional with 10 years of experience in the field. Her passion and area of expertise is environmental compliance in the aviation industry. As the Manager of Environmental Compliance Programs at Air Canada, Lexie supports ground and flight operations in meeting their environmental obligations. Through this article, Lexie Bullock, Manager of Environmental Compliance Programs at Air Canada, shares insights from her career and the challenges of maintaining environmental compliance in the aviation industry. Starting her journey as a field technician, she progressed through roles in waste management, industrial compliance and now aviation. She discusses the critical challenge of navigating compliance during the COVID-19 pandemic and highlights the growing importance of sustainable aviation fuel (SAF) and emerging regulations aimed at emissions reductions. A Journey in Environmental Stewardship My professional journey started as a field technician in the municipal sector, focusing on waste management and water resources. I was fortunate to gain hands-on experience early in my career, including surface and groundwater sampling, landfill methane monitoring and hazardous waste management. After this, I pivoted to the industrial sector, where I worked for a paper manufacturing company. Here, I identified environmental risks in the operations and implemented process changes to meet regulatory requirements related to spills, waste and effluent treatment. This led me to my role at Air Canada, where I support our ground and flight operations in meeting compliance with environmental legislation. I work with a team of experts who develop and manage programs related to wastewater, storage tanks, hazardous waste, air pollution and other areas of environmental compliance. Maintaining Compliance During Crisis The biggest challenge I encountered while working in the aviation industry was maintaining environmental compliance during the

Ammunition on city streets remains a key focus in global security discussions. While larger or ample calibers often receive regulatory attention, small arms ammunition is frequently overlooked, even though it drives most street-level violence and illicit trade. The public and international organizations such as the UN and NATO continue to call for greater accountability, yet clear pathways for implementing effective traceability remain limited. Bullet ID, a Canada-based platform, is helping to bridge that gap. Its end-to-end traceability doesn’t just track where ammunition goes but documents how each round is manufactured and what materials are used to ensure data integrity across jurisdictions. Marked with a unique identifier during high-speed laser engraving at the point of production and linked to a secure digital record, each round becomes individually traceable. The system captures the full lifecycle, from raw material inputs and batch-level manufacturing to packaging and deployment. Integrated directly into the production workflow, Bullet ID delivers this level of visibility at an industrial scale, without slowing throughput, whether 500,000 or several million rounds per day. “If a cartridge is found in the field, on a base or in a civilian setting, it can be traced back to the exact case it shipped in and its distribution point,” says Cristian Talle, CEO. “This gives defense forces the ability to monitor inventories precisely, investigate diversion risks and improve accountability across the supply chain.” This is especially timely as NATO-aligned countries seek to manage joint stockpiles more effectively and prevent expired or counterfeit rounds from entering circulation. Estimates suggest that 20 percent of global ammunition circulates outside formal systems, affecting public safety and regional stability. Bullet ID addresses this vulnerability with a system built on open, internationally recognized standards for secure interoperability. Without overhauling existing infrastructure, governments can link every round to metadata like shelf life, deployment history and location. The result is an ammunition ecosystem that’s secure and data-ready. “We’re not here to regulate—we’re here to empower. BulletID helps manufacturers deliver smarter, safer, and more trusted munitions,” says John Tsihlis, commercial director. “We’re seeing a shift: defense and law enforcement authorities both want accountability for ammunition inventories, but without complexity. BulletID delivers exactly that!”.
