ERO COPPER PUBLISHES 2021 SUSTAINABILITY REPORT

Ero Copper Corp. has published its 2021 sustainability report. The report provides an update on the company's strategy, practices, performance and management approach to key environmental, social and governance (ESG) topics. The report is available on Ero Copper's website.

"This report showcases the excellent work being performed on sustainability across our organization, as well as our commitment to clear and transparent disclosure for all of our stakeholders," said David Strang, Ero Copper's chief executive officer. "This is our third annual sustainability report, and I'm pleased that each year, we have meaningfully enhanced our disclosure. Of note, this year, we have provided broader quantitative data on our health and safety performance, greenhouse gas (GHG) emissions and intensity, as well as the economic value generated and distributed in the regions we operate. In particular, I'd like to highlight our favourable position as one of the lowest GHG-intensive copper and gold producers in the world driven by Brazil's leadership in renewable energy combined with the high-grade nature of our mines. Although we are proud of our relative positioning, we believe that we can continue to improve our GHG emissions intensity and are committed to providing GHG emissions targets in our 2022 sustainability report.

"Our 2021 report includes an update on the work we are doing to align the company with the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD), as well as our first annual communication on progress (CoP), which highlights our commitment and progress towards advancing the 10 principles of the United Nations Global Compact within our business. I look forward to continue executing on our 2022 sustainability goals throughout the duration of this year and further advancing our ESG practices and disclosures."
