A tech startup recently introduced a revolutionary app that helps users track their carbon footprints. The CEO stated, "Since using our app, many users have reported significant reductions in their carbon emissions. This shows that our app is invaluable in combating climate change." However, a technology reviewer noted, "The app’s effectiveness should not be judged solely on user reports, as it lacks scientific validation proving that using the app leads to real-world emissions reductions."
