In July 2023, the International Maritime Organization revised its GHG Strategy to commit the marine shipping industry to reach net-zero emissions by or around 2050. The current long-term target is aligned with the Paris Agreement’s 1.5°C goal. In light of the sector’s decarbonization strategy, this research explores to what extent achieving these goals will also reduce emissions of harmful pollutants – such as sulphur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM2.5) and volatile organic compounds (VOCs) – and in turn, benefit the health of coastal and port communities in Canada.
To answer this question, this project is developing an integrated modelling framework that links policy scenario analysis, emissions and air quality modelling, and health impact analysis.
The research team conducted a survey of multi-sectoral expert opinions on future decarbonization pathways for the maritime shipping industry. This expert input will enable the development of future emissions scenarios for greenhouse gases and other air pollutants from ships to improve air quality modelling tools in Canada. The project also included a MITACS-funded sub-project on developing policies for methane slip mitigation. This sub-project identified and evaluated measures and policy strategies to reduce methane slip on LNG-powered marine vessels.
