据路透社7月23日伦敦报道，全球最大的上市矿业公司必和必拓周二表示，将在五年内投资4亿美元(3.21亿英镑)，以减少其自身业务和资源使用所产生的排放。

必和必拓是最大的炼焦煤生产商，炼焦煤与必和必拓开采的铁矿石一起用于炼钢，这个过程产生数百万吨二氧化碳。

必和必拓首席执行官安德鲁·麦肯齐在伦敦发表讲话时表示，该公司的“气候投资计划”将扩大技术规模，以帮助公司自身业务脱碳，并推动投资以抑制下游排放。

“我们必须对整个价值链中的排放承担产品管理职责，并承诺与我们产品的托运人、加工商和用户合作，以 减少范围3的排放，”他预计会根据他的评论提前摘录说。

排放分为几类。范围1和2涵盖组织的直接排放和由其购买的电力产生的间接排放。

范围3排放是在使用公司产品时引起的，例如在炼钢或运输到客户时。

必和必拓的投资相当于去年8月公布的89.3亿美元全年基础利润的约5%。

必和必拓与其他矿业公司不同，其目标是在本世纪下半叶实现净零排放，符合联合国的碳减排目标。

预计它将在周二表示，希望更进一步，为范围1和2的排放设定一个以科学为基础的中期目标。其他措施还包括加强排放业绩与高管薪酬之间的现有联系。

BHP to invest $400 million to curb climate-changing emissions

The world’s biggest listed miner BHP (BHP.AX) (BHPB.L) said on Tuesday it would invest $400 million ( ￡321 million) over five years to reduce emissions from its own operations and from those generated by the use of its resources.

BHP is the biggest producer of coking coal, which is used with iron ore, also mined by BHP, to make steel in a process responsible for millions of tonnes of CO2.

At a speech in London, BHP CEO Andrew Mackenzie was due to say the company’s “climate investment programme” would scale up technology to help decarbonise the company’s own operations and drive investment in curbing downstream emissions.

“We must take a product stewardship role for emissions across our value chain and commit to work with shippers, processors and users of our products to reduce scope 3 emissions,” he was expected to say, according to advance extracts of his comments.

Emissions are divided into categories. Scope 1 and 2 cover direct emissions by an organisation and indirect emissions generated by power it buys to run its operations.

Scope 3 emissions are caused when a company’s products are used, for instance in steel-making or when they are shipped to customers.

BHP’s investment is the equivalent of roughly 5% of its most recent full-year underlying profits, announced last August, of $8.93 billion.

BHP stands apart from others in the mining sector with its target of net zero emissions by the second half of the century, in line with U.N. carbon-cutting goals.

It was expected to say on Tuesday it wished to go further and establish a medium-term, science-based target for scope 1 and 2 emissions. Other measures will include strengthening an existing link between emissions performance and executive pay.
