“Specifically, we’re calling for a price on carbon, increasing the proportion of natural gas in our business, investing in renewables and low-carbon innovation, and pursuing increasing energy efficiency,” he said.
A spokesman for Shell said it backed the goal of a “net-zero emissions world by 2050”. “The greatest contribution we can make in the near term is providing more natural gas to replace coal in power generation, which reduces overall emissions in the global energy system,” he said.
Diamond giant De Beers, part of Anglo American – which charted 31st on CDP’s list – recently announced plans to be the world’s first carbon neutral miner within five to 10 years. It wants to use waste rock from mining to absorb carbon in the atmosphere through a process called mineral carbonation.
“Since the 2015 Paris Agreement on climate change, there has been a huge jump in carbon pricing schemes,” said Dr Evelyn Mervine, a geologist at De Beers. “What’s clear is there will be carbon pricing by 2030s – it will be a cost of doing business.”
