Dear Maritime New Zealand,

Subject: Analysis of atmospheric and climatic impacts of shipping emissions

Request:

I request copies of any documents held from 1 January 2015 to present that:
1. Assess or analyse the atmospheric impacts of shipping emissions, including:
• sulphur dioxide (SO₂)
• sulphate aerosols
• particulate matter
2. Evaluate or discuss:
• aerosol–cloud interactions
• cloud condensation nuclei (CCN)
• cloud formation or reflectivity
• rainfall or precipitation effects
3. Relate to implementation or impacts of:
• MARPOL Annex VI
• Marine Protection Rules Part 199
4. Include any modelling, monitoring, or scientific assessments of:

If no documents exist that evaluate rainfall or cloud effects, please confirm that no such analysis has been undertaken or is held.

Kind regards,

Spencer Jones
