The Climate Change (Emissions Reduction Targets) (Scotland) Act 2019 sets the ambitious net-zero greenhouse gas (GHG) emissions reduction targets by 2045. This report provides an updated assessment of the emission reduction potential of the most effective mitigation measures in Scotland. The research team assessed 25 distinct farm technologies (in total 39, when considered for different livestock types) and practices which can reduce GHG emissions in Scotland by 2050. The measures were derived via a systematic process taking forward the most suitable options for Scotland for quantitative modelling.
