What are ASX 200 investors considering?
The Rio Tinto share price is in the green on the back of another leg up for iron ore prices.
The industrial metal broke back above the US$100 mark yesterday and gained another 2.4% overnight to US$101.25 per tonne. That's the highest price in more than two months amid new Chinese government stimulus for the nation's property markets.

In other news likely to draw the interest of ESG-focused investors, the miner announced it will invest another $600 million in renewable energy assets in the Pilbara. The new investment is part of Rio's ongoing effort to decarbonise its Western Australian iron ore operations.
Rio Tinto intends to construct two 100MW solar power facilities and 200MWh of on-grid battery storage by 2026.
Commenting on the new renewable energy investments, Rio Tinto Iron Ore CEO Simon Trott said:
The Pilbara is extremely well-positioned to take advantage of renewable power with land, access to people, and abundant wind and solar resources. Our Pilbara electricity grid is the largest privately-owned grid in Australia, ensuring that we have the initial infrastructure required to enable a transition to renewable energy.
We expect to invest around $3 billion to install renewable energy assets as well as transmission and storage upgrades in the Pilbara as part of our commitment to halve our emissions from the Pilbara by the end of this decade.
