In 2023, the UK recorded nitrous oxide emissions amounting to 16.8 million metric tons of CO2 equivalent. This emission figure is projected to decrease steadily over the next years, reaching 14.8 million metric tons by 2028. From 2024 to 2025, emissions are forecasted to drop by 2.67%, with subsequent annual reductions of roughly 2.61% and 2.75% leading into 2026 and 2027 respectively. Over the five-year span from 2024 to 2028, the compound annual growth rate (CAGR) indicates an average decline of 2.66% in emissions annually.

Future trends to watch for:

Monitoring the progress and impact of UK policies on agricultural practices, which are significant contributors to nitrous oxide emissions.
Technological advancements in emission control and their adoption rate across key sectors.
Potential regulatory changes or international agreements targeting greenhouse gas emissions reduction.
Economic activities and industrial developments which could potentially influence emission levels.
