Quantitative Assessment of Greenhouse Gas Emissions in New Zealand Using Exploratory Data Analysis and Statistical Modelling Approaches

This study analyzes New Zealand-sourced greenhouse gas data to identify trends and factors of emission. These findings are expected to guide and enable the creation of efficient policies and sustainable practices supportive of New Zealand's goals on climate change for a greener and sustainable future. The study tries to highlight the rising greenhouse gas levels which have been impacting agriculture, transportation, and public health. New Zealand's industrial landscape is so diverse that it provides a very special opportunity to study the trends in emissions and identification of effective mitigation strategies. The review covers major trends by sector, region, and household activities from 2007 to 2022. Based on the findings, agriculture is the largest contributor to emissions, accounting for 18.6% of total GHG outputs. Primary industries, forestry, and fishing are also big contributors, while urban transportation shows a flat trend. Regional disparities are reflected, with Waikato, Canterbury, and Auckland having the highest emissions.
