Abstract: As a dry medium and low vacuum pump, screw vacuum pump has many advantages such as wide pumping speed range, low energy consumption, no oil pollution, etc., and is widely used in various fields. In order to serve the national carbon neutral development strategy, this paper applies the accounting and management method of carbon footprint to the design and manufacture of screw vacuum pumps. By tracking, analyzing, accounting and managing the carbon footprint of the entire product life cycle, specific measures to reduce carbon emissions are put forward from the perspective of design, processing and manufacturing, supply chain transportation and institutional levels. The research of this work will help enterprises to formulate relevant carbon neutral goals, complete the accounting of carbon footprint, and achieve the purpose of energy saving and emission reduction.

Key words: screw vacuum pump, carbon peak, carbon neutrality, carbon footprint accounting, energy saving and emission reduction
