Material actions and disclosures
Scope 1 emissions dropped 7.8% year-on-year, mainly due to a 20% decrease in fleet emissions. Scope 2 emissions reduced 66% year-on-year, primarily due to a decrease in the grid emissions factor. The company reduced its reported scope 2 emissions by 2,270 tCO2e through a ten-year renewable energy partnership with Genesis Energy.
Spark also committed to a 56% reduction in absolute scope 1 and 2 GHG emissions by FY30 from a FY20 base year. The company aims for 70% of its suppliers by spend to have science-based targets in place by FY26.
Scope 1 and 2 emissions were restated to reflect the sale of data centre operations to TenPeaks in January 2026, and the FY20 base year for reporting was rebaselined to 15,574 tCO2e, reflecting the new organisational boundary.
Spark’s emissions reduction target has been verified by the SBTi as consistent with a 1.5°C pathway to FY30.
According to the company’s announcement, the reductions were achieved through a combination of operational changes, boundary adjustments, and the retirement of Renewable Energy Certificates (RECs).
