The term 'carbon footprint' has gained popularity since its introduction in 1999, helping individuals understand their environmental impact. However, researchers argue it has shifted the burden of climate responsibility to individuals rather than policymakers and businesses. Critics highlight the term's ineffectiveness in prompting action from decision-makers and its association with greenwashing by oil companies. Experts advocate for a broader approach to measuring sustainability and suggest that focusing on resource security rather than guilt over carbon footprints may be more effective in driving change.
