Can other land-based approaches to greenhouse gas removal, such as enhanced weathering and biochar, help achieve net zero without negative environmental impacts?

Background

To limit future warming requires rapid reduction of greenhouse gas (GHG) emissions and achieving net zero by 2050, as required by UK legislation. Climate mitigation is led in government by the Department of Business, Energy and Industrial Strategy (BEIS). But Defra is responsible for efforts to reduce GHG emissions from four sectors: agriculture, waste and wastewater, land-use, and fluorinated gases (F-gases). Defra also has responsibility to promote forestry, which acts as a carbon sink. Together, the four Defra sectors represent 15% of the total net UK GHGs, with agriculture being the biggest contributor (about 10% of UK emissions).

Defra has research interests in reduction of emissions, the removal of GHG from the atmosphere, and in understanding the impacts of mitigation activities on other environmental outcomes.
