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.
