Abstract: The increasing carbon emissions from fossil fuel combustion and land use change will lead to disastrous global warming in the near future, so it is widely recognised as one of the most challenges facing human societies. In this paper, we will assess the atmospheric carbon dioxide removal and recycling utilisation which can turn anthropogenic carbon emissions from carbon pollution into valuable resource and then satisfy the needs of sustainable development goals (SDGs). The direct removal of atmospheric carbon dioxide is mainly through direct air capture, sustainable biochar, desert geoengineering, and ocean fertilisation. Captured atmospheric carbon dioxide can further be utilised in the synthesis of various fuels or enhance of traditional energy production. This novel approach can bring the atmospheric carbon dioxide back to the energy cycle, converse fossil energy into carbon-neutral energy, and then achieve the recycle of carbon dioxide resource.

Keywords: carbon emissions; carbon dioxide removal; carbon dioxide utilisation; carbon-neutral fuel; sustainable development goals; SDGs.
