For comparison purposes, the global warming potential of 1 million tonnes of N20 is equivalent to 265 million tonnes of carbon dioxide.) Reduction strategies could potentially hold emissions at 4.1 million tonnes in 2030 and cut them to 3.3 million tonnes by 2050. However, offsetting the projected increases in emissions under the business-as-usual scenario for the year 2030 would require the adoption of all five of the emission reduction strategies presented in Table 11, including behavioural changes such as reducing animal protein in diets, making the reduction estimates uncertain.
