VanEck Sustainable World Equal Weight vs Xtrackers MSCI World ESG

They track different indices: VanEck Sustainable World Equal Weight follows MarketGrader Sustainable World Equal Weight and Xtrackers MSCI World ESG follows MSCI World Low Carbon SRI Leaders. They also differ in cost (0.30% vs 0.20% TER), replication (physical vs physical) and domicile (Irlanda vs Irlanda).

Nobody can know that: they track different indices, so their returns will diverge, and past index performance is not a prediction. What you can control today is the cost, the tax structure and whether the index actually covers what you want exposure to.

Xtrackers MSCI World ESG has the lower annual fee. Applying the same 7% gross return to both with €300/month, that fee gap alone is worth about €1,853 after 20 years — that part is arithmetic, not a forecast.

Both are accumulating, so on this point there is no difference between them.

Yes. Unlike two funds tracking the identical index, these give you genuinely different exposure, so holding both is not automatically redundant — just be aware you may end up overlapping on the largest companies and doubling your rebalancing work.
