今天，我们宣布了重大的新环境目标，因为我们努力增长3M并提高对价值观的承诺。We have a long record of environmental stewardship, and we’ll do even more going forward to improve both air and water quality – including a commitment to become carbon neutral by 2050. Over the next 20 years, we expect to invest approximately $1 billion to accelerate ongoing efforts to improve our operations and deliver on these new environmental goals.
