NTT西日本 builds gen-AI consulting method on 約1,000自治体 plans

The announcement lands against Japan's 2050 carbon-neutral goal, which asks municipalities nationwide to cut greenhouse gas emissions across their areas. The regional version of the local government execution plan is the document meant to carry that work, but NTT西日本 notes that preparing it takes heavy time for legal checks, local analysis, statistics gathering and aligning with related plans, and demands broad expertise to turn local traits into effective measures.

NTT西日本's answer is to combine its own GX consulting knowledge with a program that draws on published plans from roughly 1,000 municipalities. The company says the program runs in a closed environment to limit leakage risk, and clarifies the sources of the data it uses to curb hallucination — the tendency of generative AI to produce factually wrong content. It also lets consultants reference good examples from other municipalities facing similar issues.

Looking ahead, the company says it will move from plan-drafting support to helping execute measures such as renewable energy and energy savings, and to offering PPA and subsidy support in one package. The test is likely whether municipalities actually adopt the method, since the release names no specific deployment or price.
