The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. —Dunmore et al.

Study finds warming caused by synthetic greenhouse gases could outweigh climate benefits from phasing down CFCs

Chlorofluorocarbons (CFCs)—commonly used in refrigerators and air conditioners—play a role in creating a hole in the ozone layer over Antarctica. HFCs are particularly strong greenhouse gases, so even relatively small levels in the atmosphere can contribute to warming.

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. Of that, international shipping accounts for 83% (870 TgCO 2 yr ?1

In their extensive analysis of the physical and chemical composition of the emissions, McDonald and colleagues found that the most abundant pollutants were carbon dioxide, carbon monoxide, NO, and NO 2. This phase was conducted at SwRI in 2012. These ancillary studies evaluated endpoints not examined in the core study.
