OCE-B.09.B - ALDM Prevention and Reduction Measures
Does the company implement measures to prevent and reduce ALDM in its operations and supply chain?
About the data
The WBA Ocean Benchmark measures and ranks the world's most influential companies on their efforts to halt and reverse nature loss in marine ecosystems, tracking how companies manage their impacts on ocean biodiversity, marine habitats, and the communities and workers dependent on healthy seas. The 2026 edition is WBA's first Ocean Benchmark, assessing 125 companies across key sectors dependent on oceans, including seafood, maritime transport, offshore wind energy, shipbuilding, port operations, apparel, and chemicals. Companies are assessed on 47 indicators across four measurement areas: governance, ecosystems and biodiversity, social responsibility, and core social indicators. The benchmark builds on WBA's Nature Benchmark and the former Seafood Stewardship Index, and its methodology was developed with input from more than 50 stakeholders including ocean communities, companies, scientists and civil society, with human rights and social impacts kept at its core alongside nature-specific concerns.

Methodology
Over the past decade, significant attention has been given to the issue of abandoned, lost
and discarded fishing gear (ALDFG) – often referred to as ‘ghost gear’ – and its detrimental effects on
the marine environment, including ghost fishing, entanglement and habitat damage. This concern has
been heightened by the growing awareness of plastic pollution and its severe impact on marine
ecosystems, with ALDFG contributing significantly to the problem. The amount of ghost gear found in
oceans is estimated to be at least 640,000 tonnes annually (FAO, 2018; WWF, n.d.)
The term ALDM used in this indicator additionally includes material from other sectors, such as
aquaculture operations, marine transportation, or land-based material that can represent a substantial
portion of marine litter. With the ongoing global expansion of aquaculture, which now provides over
half of the world's seafood, there is a need to address the ALDM issue at the farm level. This indicator
also requires companies from other sectors to account for marine litter, defined by the United Nations
Environment Programme as ‘any persistent, manufactured or processed solid material discarded,
disposed of or abandoned in the marine and coastal environment’ (UNEP-FI, 2021), and contributes to
SDG 14.1, which aims to prevent and significantly reduce marine pollution of all kinds.
Research Guidance:
For this element to be **met**, the company **must** :
describe activities to prevent and reduce ALDFM.
Examples:
Collection or recycling of nets, technologies for recovery, and reduced incidence of lost material.
Sustainable fishery certification that accounts for ghost gear (MSC)
Company example: Nueva Pescanova's activities they implement to reduce ALDFG (p6-7).
