What is a Carbon offset / Carbon balance?

Affordable carbon dioxide emission financial instruments used to achieve carbon neutrality targets.  They are used to offset the carbon dioxide emissions produced by companies or individuals. Carbon offsets, which are equivalent to the carbon emissions they produce, help them become carbon neutral. The sources of carbon offsets are: renewable energy, methane gas combustion, energy efficiency, industrial pollutant removal, reforestation. The aim of the carbon offset financial instrument is to make people, projects, companies, governments take responsibility for the carbon emissions they cause. However, carbon offsets are seen as highly controversial by climate activists, as buying carbon emissions does not actually lead to the cessation of an environmentally damaging activity.
