You are asking for an LCA of electronic components. The best ones are proprietary, such as the one we put together at Apple ten years ago, which is probably still updated and unrivaled.
The good news is that electronic components often obey commodity pricing. And for commodities there is a very good approximation for LCA: their market price.
An LCA is a sum environmental impacts, weighted by importance. Market price represents some sort of consensus weighting. You can argue for other weightings, but such arguments are at least as subjective as the market weights and seldom give a significantly different result.
Interestingly, even non-commodities reveal their environmental impact through their price. The difference is, their prices include all downstream environmental impacts, whereas traditional LCA and commodity prices only reflect impacts within some "system boundary".
If you mean "secret", then we're not going to progress much. Impact on environment is not like impact on your finance. Your finance are private, the environment is everyone's. Therefore, everyone's must have access ton the information needed to assess if the impact is acceptable or not.
