leave additional sequestration after 2035 available for sectors like agriculture to reach net zero. So that farmers can take full advantage of the new funding, the government should develop a new Farm and Soil Carbon Code, based on the model of the existing Woodland Carbon Code. This would expand the scope for quality checked and marketable services for plant and soil carbon sequestration in the UK. The government should also factor in the UK’s share of international aviation emissions to its domestic net zero obligation, and secure an international agreement to reduce global aviation emissions, in line with the Paris climate agreement goal to limit global heating to 1.5oC. Once the two risks of offsetting are addressed, there will be considerable advantages in the approach we describe: it will fund vital carbon removals in parallel with action to reduce emissions, and it will allow high standard providers of carbon removals to show what a good carbon credit looks like. This will set a quality benchmark for other CORSIA participants, and help to build an exemplary carbon removal industry in the UK, which will be necessary to comply with the net zero law.
