Environmental pollution, ecological destruction, and waste of resources are increasingly threatening human existence. The Chinese government has set the goal of “carbon peaking by 2030 and carbon neutrality by 2060” to promote green and sustainable development. Under the background of the green and digital era, it is necessary to promote green and sustainable higher education. It is of great theoretical and practical value to discuss the acceptability of green technology in higher education teaching. This paper takes the acceptance evaluation of green technology into college foreign language teaching as the object, constructs the acceptance evaluation index system based on the Delphi method, selects the entropy weight TOPSIS model to evaluate the acceptance, and finally tests the main factors affecting the acceptance through the whole and grouping regression models. The main conclusions are as follows: (1) Based on the Delphi method, a five-dimensional acceptance evaluation index system including “teaching mode, teaching skills, teaching ideas, teaching content, and teaching effects” can be constructed. (2) Based on the entropy weight TOPSIS model, it is found that the relative proximity Z value of the acceptance of green technology into college foreign language teaching has significant heterogeneity. (3) Through multiple linear regression analysis, it can be found that the evaluation subjects’ dependence on green technology, imagination, educational equity, and interpersonal interaction have the greatest impact on their acceptance. The scientific and rational use of green technology tools such as digital technology will become a possible direction for the reform of intelligent foreign language teaching.
