Beyond cutting fossil fuel emissions, achieving climate change targets will require active carbon dioxide reduction (CDR) technologies. Implementation of these technologies will require suitable tools for measuring, reporting, and verifying carbon uptake, and understanding and monitoring potential environmental impacts. This project will investigate these questions through two emerging marine-based CDR technologies: alkalinity enhancement and algae carbon sequestration.

• Assess the current national and international legal framework for the application of carbon dioxide reduction technologies;
• Develop monitoring approaches for alkalinity additions in both ocean and river environments in Nova Scotia, considering the effects of mixing and sediment-alkalinity interactions;
• Address knowledge gaps in carbon reduction via algal deposition on the ocean floor;
• Develop optimal approaches to monitor and report the effects of alkalinity enhancement on biogeochemical processes in oceans and estuaries through chemical and biological surveys;
• Engage youth and policy makers in exploring meaningful ocean/climate solutions.
