NOC Code for - energy, environment & sustainability

[NJvv]

Hello all,
I am writing seek help on the NOC code for profiles in energy, environment & sustainability. I have a Bachelor in Civil Engineering and a MS in Environmental Engineering with the following work experiences. Could anyone please suggest the appropriate NOC code for this profile.

@legalfalcon Since my max work experience has been as an energy & sustainability consultant and BE & MS have been in engineering, I am wanting to be sure whether the NOC Code for natural resources & applied science - 4161 or the one for management consulting - 1122 or the civil engineering one would be applicable.

1.5 years in energy procurement, clean energy, carbon emissions, energy news and policy analysis & sustainability as an Energy Consultant
0.5 years in environmental impact assessment, water, land use and sustainability as a Research Intern
0.4 years in energy - emissions analysis, environment and sustainability as an Energy Intern
0.4 years in drone mapping & analyzing land use change as a Project Lead

Thanks in advance for your inputs!
