Carbon Dioxide is a gaseous pollutant with the chemical formula CO₂. It has no colour, no odour and no taste. It is considered non-flammable as it is the end product of carbon combusting in oxygen. 

Carbon dioxide emissions are predominantly a result of combustion of carbon-based or fossil fuels such as coal, biomass, oil, natural gas and biogas. The dominant sources of CO₂ emissions in the UK is combustion for the purposes of electricity and gas production; road transport and residential fuel combustion also are significant contributors.. 

Carbon dioxide is widely known to be a dominant greenhouse gas, which is significantly contributing to the rise in global temperatures due to the increasing greenhouse effect (trapping solar radiation within the earth’s atmosphere). 

In high localised concentrations, CO₂ is considered a workplace hazardous as it can cause headaches, dizziness and loss of consciousness (asphyxiation).. 

The primary focus of carbon dioxide control is based on the attempt to reduce production and general shift to using alternative sources of energy and transportation that do not involve fossil fuel combustion. 

There have been several and varying approaches to the removal of CO₂ directly from the atmosphere, including direct air capture (DAC) Abatement technology including injecting CO₂ enriched gases with amines or calcium oxide to trap or chemically combine with CO₂ (scrubber). As well as increasing focus on restoration natural ecosystems including oceans and which act as significant carbon storage sinks through natural carbon sequestration. 

There is also expanding scope into the alternative production of energy through greener or alternative sources of energy and transport. 

Alkali Environmental perform periodic measurements of Carbon Dioxide in ducted emissions from point sources to the standard reference method PD CEN TS 17405. The reported results carry UKAS and MCERTS accreditation where the method can be performed to the standard. 

These measurements are taken using an on-line combustion gas analyser where instantaneous and logged results can be taken.
