Centre says Delhi saw best air quality this year since 2016, CM responds

The Ministry of Environment has said Delhi saw the highest number of 'good to moderate' air quality days this year since 2016. This data doesn't include 2020 when a lockdown was imposed due to COVID-19. Reacting to this, Delhi CM Arvind Kejriwal said, "This was perhaps the most difficult task — improving air quality. But a series of steps...helped us."
