London Stock Exchange Group scores 55/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified August 2026.

That places London Stock Exchange Group joint 34th of 596 companies scored, and 2nd of 35 in Financial Services / Banking.

LSEG publishes detailed carbon and resource data with third-party assurance, but Scope 3 lacks binding absolute targets for its largest emission source (purchased goods, 78% of total). Material gaps: Tradeweb excluded from carbon boundary; recycling rate declining; water and nature strategies documented but without quantified reduction targets. Structurally exposed as financial infrastructure serving fossil fuel clients.
