• In the Introduction, figure 1.2 (p. 39), 'offshore migration' has been corrected to 'offshore mitigation'.
• In Chapter 3, figure 3.14 (p. 78) previously listed gross emissions in 2021 as 1.14 MtCH4 and 0.64 in 2050. This has been corrected to 1.30 MtCH4 in 2021 and 0.8 in 2050. The listed reductions in the figure were accurate.
• In Chapter 4, 'Energy' (p. 85) previously stated 'electricity demand would increase by 59% from 2022 to 2050'. This has been corrected to 64%.

• In Chapter 4, 'Transport' (p. 93) previously stated 'would reduce overall distances travelled by vehicles by 15% in 2040'. This has been corrected to 18%.
• In Chapter 4, ‘Agriculture’ (p. 99) previously stated ‘methane reducing technologies would reduce emissions by 4 MtCO2e in the fourth budget period.’ This has been corrected to 1.05 MtCO2e.
• In Chapter 4, ‘Agriculture’ (p. 99) previously stated 'We assume land currently used for dairy is converted to horticulture at a rate of 2000 ha per year'. This has been corrected to 1,103 ha per year.
