The adoption of the Paris Agreement to reduce greenhouse gas emissions by 45% by 2030 and achieve net zero emissions by 2050 [1] has created an opportunity for countries, especially in their energyintensive industries to phase out these energy sources and move to low-carbon renewable sources. Since energy generation is a major contributor to emissions, it has been found that the most effective way to implement decarbonization strategies is through target setting and tracking of energy usage. Most businesses, especially the intensive energy users and those publicly listed have thus been constantly tracking their emission levels through energy usage and efficiency to meet the 2030 targets and ultimately, the 2050 net zero emissions target. In this study, sustainability targets of the Top 100 listed companies by market capital on the Johannesburg Stock Exchange (JSE) in South Africa have been reviewed to find the correlation between energy efficiency targets and their corporate sustainability goals. Of the 100 evaluated companies, 76 have energy efficiency targets and are deemed to be on track to achieve their GHG emission reduction targets. This target-setting and reporting approach has further assisted some companies in innovating their business practices without any major impact on their business operations.AbstractenCorporate sustainabilityEnergy efficiencyNet Zero EmissionsTop 100 JSE listed CompaniesSustainability targetsConference PresentationN/A
