Net Zero is a very topical subject across all sectors of society at the moment. It refers to the balancing of carbon emissions produced from human activity. Many governments and corporations are making commitments to achieving Net Zero by the year 2050. Despite the food industry making strides towards getting to Net Zero there is significant changes required if it is to get anywhere near Net Zero. Agriculture remains one of the biggest offenders particularly looking at a country like Ireland where agricultural emissions are the largest source of carbon emissions of any sector. The study seeks to understand the major causes behind carbon emissions and how to negate this in achieving Net Zero. The Agricultural impacts will be examined in both Ireland and globally, looking at causes of emissions along with successful examples of mitigating emissions in achieving Net Zero. The Study will examine potential technological advances that give hope for achieving Net Zero. There is a detailed review on how policy makers look to tackle this issue and how that relates to the food industry. There are many studies highlighting how Net Zero is perceived by both individuals and their impacts from shifting to a more plant-based diet along with sectors in the food industry in implementing changes that will allow them to achieve Net Zero. The study is an overall review in how Net Zero can be achieved in the food industry for a more sustainable and waste reduced circular model.
