British Rail Class 55 Deltic diesel locomotive with their characteristic dense exhaust when starting a train.
Diesel exhaust is the gaseous exhaust produced by a diesel type of internal combustion engine, plus any contained particulates. Its composition may vary with the fuel type or rate of consumption, or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator or other application.[1]
Diesel exhaust is a Group 1 carcinogen, which causes lung cancer and has a positive association with bladder cancer.[2][3][4][5][6] It contains several substances that are also listed individually as human carcinogens by the IARC.[7]
Methods exist to reduce nitrogen oxides (NOx) and particulate matter (PM) in the exhaust. So, while diesel fuel contains slightly more carbon (2.68 kg CO₂/litre) than petrol (2.31 kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower due to higher efficiency. In use, on average, this equates to around 200 g CO₂/km for petrol and 120 g CO₂/km for diesel.

The scientific evidence was reviewed thoroughly by the Working Group and overall it was concluded that there was sufficient evidence in humans for the carcinogenicity of diesel exhaust. The Working Group found that diesel exhaust is a cause of lung cancer (sufficient evidence) and also noted a positive association (limited evidence) with an increased risk of bladder cancer
^"Report on Carcinogens: Diesel Exhaust Particulates" (PDF). National Toxicology Program, Department of Health and Human Services. October 2, 2014. Exposure to diesel exhaust particulates is reasonably anticipated to be a human carcinogen, based on limited evidence of carcinogenicity from studies in humans and supporting evidence from studies in experimental animals and mechanistic studies.

After a week-long meeting of international experts, the International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), today classified diesel exhaust as probably carcinogenic to humans (Group 1), based on enough evidence that exposure is associated with an increased risk of lung cancer.
