Should governments formally classify underwater ship noise as a regulated form of marine pollution?
South Africa, Chile, and Georgia have submitted a global gap analysis to the International Maritime Organization (IMO) detailing the absence of national legislation that classifies underwater ship noise as pollution. This research was produced under the GloNoise Partnership.
Why it matters
The study highlights a critical lack of baseline acoustic data and economic incentives, which currently prevents effective global regulation to mitigate the impact of shipping noise on marine life.
The analysis, presented at the 85th session of the IMO Marine Environment Protection Committee, examined legal instruments and policies via questionnaires and literature reviews across 6 pilot countries.
The players
International Maritime Organization
The United Nations specialized agency responsible for the safety and security of shipping and the prevention of marine and atmospheric pollution by ships.
GloNoise Partnership
A collaborative initiative involving the Global Environment Facility, the UNDP, and the IMO focused on building capacity to manage underwater noise from shipping.
The details
Researchers utilized questionnaires sent to focal points alongside targeted meetings to evaluate how existing legal frameworks address acoustic disturbance. The study identified that while guidance exists, nations lack the specialist acoustic skills and baseline noise measurements required to draft enforceable national standards. Current legal instruments also provide no economic incentives for the shipping industry to adopt noise-reduction technologies.
Timeline
October 2026: Findings were submitted to the 85th session of the IMO Marine Environment Protection Committee.
The Tech Race
This research serves as a foundational step for the GloNoise Partnership as it works to standardize acoustic metrics across international waters. The effort aims to mirror the regulatory trajectory of chemical pollutants by establishing a clear legal definition for noise in marine environments.
This policy gap analysis identifies the regulatory hurdles that prevent the shipping industry from adopting uniform noise-reduction standards. Future national legislation resulting from these findings could eventually mandate new acoustic engineering requirements for commercial fleets.
The takeaway
The lack of baseline data and legislative recognition remains the primary barrier to addressing shipping noise as a pollutant. Observers should track subsequent IMO Marine Environment Protection Committee sessions to see if these findings trigger the development of formal international noise standards.
