Harbours Review Spotlight: Greenhouse Gas Emissions in Shipping – with IMO’s recent decision to cut greenhouse gas emissions from shipping by 50% compared to the base year (2008) by 2050, there is a need to carefully examine the shipping industry’s current state and create a clear path to reaching this highly ambitious goal.
Reducing greenhouse gas (GHG) emissions is the key to avoiding the most catastrophic impacts of climate change. Despite international shipping being excluded from the Paris Agreement, the International Maritime Organization (IMO) is developing its own strategy to reduce GHGs from ships. IMO member states will need to understand recent trends in ship activity and emissions to develop an effective strategy. Policymakers would benefit from the most recent understanding of the drivers of shipping emissions (e.g., transport demand, ship capacity, and speed), in order to make informed decisions.
