The health and environmental impact of transport is significant because transport burns most of the world's petroleum.This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide.
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, [1] or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe , flue gas stack , or propelling nozzle .
British Rail Class 55 Deltic diesel locomotive with their characteristic dense exhaust when starting a train. Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates.

Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel.In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from a reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel.
Among all human activities, fossil fuel combustion is the largest contributor to the ongoing buildup of carbon in the Earth's biosphere. [10] The International Energy Agency and others report that oil & gas use comprises over 55% (18 billion tons) of the recorded 32.8 billion tons (BT) of CO 2 released into the atmosphere from all energy ...
Soot, particularly diesel exhaust pollution, accounts for over one-quarter of the total hazardous pollution in the air. [12] [22] Among these diesel emission components, particulate matter has been a serious concern for human health due to its direct
Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution.The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.
