evidence: Prime Minister Narendra Modi today said his government has distributed 10 crore LPG connections in four years, including four crore free to poor women of which 45 per cent beneficiaries have been Dalits and tribals resulting in a "big social transformation". [...] Interacting through video-conference with some women beneficiaries who received free cooking gas connection under the Ujjwala Yojana, a flagship welfare scheme aimed at increasing LPG coverage among the poor, the prime minister said 10 crore LPG connections have been given in the last four years as compared to 13 crore in six decades since independence. [...] Ujjwala scheme was launched in May 2016 to provide in three years as many as 5 crore free LPG connections to women from extremely poor households. It also aims to reduce the use of polluting fuels such as wood and dried cow dung that, according to the World Health Organization, cause 1.3 million premature deaths in India every year.
