Share Article Coal production from the top ten companies fell from a collective 1,704Mt in 2019 to 1,633Mt in 2020 – a 4.2% decline. The most significant declines were observed from Arch Resources (28.6%), PT Bumi (24.9%), Glencore (23.9%), and Peabody (21.8%). Production from Arch Resources (formerly Arch Coal) declined primarily due to the sale of the Holden #22 Surface mine in December 2019 coupled with weak economic conditions during Q1 2020. In addition, the temporary suspension of the Viper mine in Q2 2020 further disrupted the company’s coal production. Heavy rainfall amid the outbreak of COVID-19 impacted PT Bumi’s output in 2020.
