Nathan has led the development and implementation of a cost-effective in-house carbon accounting solution called the Impact Tracking Tool (ITT). This system reports on almost 50 GHG inventories, which represent over 100,000 tonnes of CO2 emissions. The ITT identifies trends to help Canadian enterprises target areas of high emission releases. It encourages companies to use mitigation strategies by setting science-based targets; it inspires organizations to discuss measuring Scope 3 emissions and prompts them to align with international standards. Nathan is working on engaging businesses to improve the accessibility, quality, and education around GHG measurement.
