Ecological Footprint Carbon Emissions Accounting

The ecological footprint of energy land reflects the degree of pressure on the surrounding ecological environment caused by the consumption of fossil fuels by human activities and economic development. The traditional method of measuring the ecological footprint of energy land mainly considers the CO₂ emitted after the combustion of fossil energy. This paper takes into account the difference in carbon emissions during the land use process, based on the traditional ecological footprint consumption account, and replaces the traditional ecological footprint of energy land with a carbon footprint, which can better reflect the change pattern of carbon emissions in the total ecological footprint during human activities and is closely integrated with the IPCC land use carbon emissions study. It is also possible to take into account the impact of carbon emission factors on the carbon sequestered land in the ecological footprint. $$E{F}_C=\frac{\left(E_g+E_j+E_w\right)}{\mathit{NP}}$$
In Eq. (10), ${\mathit{EF}}_C$ is the carbon footprint, $E_g$ , $E_j$ and $E_w$ denote the total annual CO₂ emissions from cropland, construction land and unused land respectively, and $\mathit{NP}$ is the average carbon sequestration capacity of grasslands, woodlands, gardens and watersheds, t/hm2.
