in 2001 that had risen to 90m tonnes

[English80s]

Is using past perfect "had risen" in the following sentence right?

"In 1989 an estimated 30m tonnes went by road, in 2001 that had risen to 90m tonnes, with further big increases expected by 2009."

"In 1989 an estimated 30m tonnes went by road; in 2001 that had risen to 90m tonnes, with further big increases expected by 2009."

Yes, that's correct.

Note that you had a comma spice in your original. After "by road", you had two choices: a semi-colon, or a full stop and a second sentence.

 

[English80s]

The past perfect is used before the past, right? Here the past perfect "had risen" is used after the past tense "went by". How do you see it? It should be "had gone by", right?

I do not see the need to use the past perfect tense when the tiiming of the two events are clearly distinguished by time markers.
