I urgently need to know if this is correct.

I want to reply this:

I've just read your last email, informing me about our French partner's decision to vary the title of the project. (I suppose the original title was just on biodiversity in water..)
As I have already told you once, we should stick to what we agreed upon during our preliminary meeting when our schools' principals were there.
As you know, I can't take any decisions on behalf of either my principal or the other teachers.
Ours is primarily a scientific project combing the study of natural sciences with English and ITC. ( Can you help me express it better).

A day late, but here goes ...

I've just read your last email, informing me about our French partner's decision to vary the title of the project. (I suppose the original title was just on biodiversity in water..)
As I have already told you once, we need to stick to what we agreed upon during our preliminary meeting when all our schools' principals were there. As you know, I can't make any decisions on behalf of either my principal or the other teachers. Ours is primarily a scientific project, combining the study of natural sciences with English and ITC.

Ignore my first response ...

To ensure accuracy and clarity in your response, here's a revised version:

"Thank you for your email. I have reviewed the information regarding our French partner's decision to modify the project title, which was originally focused on biodiversity in water. As we discussed during our preliminary meeting with our schools' principals, it is crucial that we adhere to the agreed-upon plan.

Please understand that I do not possess the authority to make decisions on behalf of my principal or the other teachers. Our project predominantly revolves around the integration of natural sciences, English, and ITC to facilitate scientific exploration. If you have any suggestions or thoughts on how we can express this objective more effectively, please feel free to share them."

Remember, it's always important to maintain a professional tone and offer the opportunity for open communication and collaboration.
