These actions resulted in a 31 percent reduction in cumulative anode effect minutes per pot day from a 2018 baseline of 0.39 anode effect minutes per pot day. This translates into improved operational efficiency, consistent aluminum production, and reduced emissions.  â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â€¯â¶Ä¯â€¯â¶Ä¯â€¯

The Lista team was able to maintain these results for more than 12 consecutive months, making 2022 their first full year with green anode effect numbers. That is, the anode effect minutes were kept below the threshold goal.  â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â¶Ä¯â€¯â¶Ä¯â€¯â¶Ä¯â€¯
