Energy company goes around making stuff for green travellers (8)

I believe the answer is:

ecotours

I'm a little stuck... Click here to teach me more about this clue!

'making stuff for green travellers' is the definition.
I can't tell whether this definition defines the answer.

'energy company goes' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mco).
'company' becomes 'co' (abbreviation).
'goes' becomes 'tours' ('tour' can be a synonym of 'go').
'e'+'co'+'tours'='ECOTOURS'

'around' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
