I'm actually working on carbon markets. Anyone knows where I could find EUA (european union allowances) futures prices intraday (15 minutes) from 2008 until now for free? Thank you for your help
Have a look at Tick Data. They sell trade (and optionally quote) data for a lot of different instruments including the EUA futures. Their pricing is 125 USD for a one year tick history and you need to order for at least 250 USD at a time.
I ordered some Eurex DAX future tick history from them. The order process was flawless and their pricing was significantly cheaper than other providers I could find (incl. Eurex directly).
