This is common sense worldwide — a fundamental principle of resource management.
Literal
This [topic-は] world [genitive-の] common-sense [being-であり], resource management [genitive-の] great-principle [is-だ].
A short but formally framed declarative. ~であり is the formal/written conjunctive form of ~である (the literary copula), used to chain clauses in essay or journalistic prose — a more buttoned-up counterpart to ~で or ~だ. The sentence ends with the plain copula だ rather than です, which in combination with であり gives it a declarative, editorial tone: the speaker is stating something as uncontestable fact. 大原則 ('great principle' = fundamental / overarching principle) is a register-marker on its own, typical of formal argumentation.
