Identification of Major Themes or Topics
In order to build the company's sustainability DNA, strengthen the company's CSR and competitiveness,and to understand the level of stakeholders' concern for sustainability issues, Nova Tech follows the content of the GRI General Principles 2021 and the guidelines of AA1000 SES, and through the following four steps (identification, ranking, implementation, and communication), identifies the sustainability issues that stakeholders are highly concerned about, analyses the positive and negative impacts that they may have, and analyses the probability of impacts and the degree of impacts through surveys, in order to identify the company's major sustainability themes. In 2022, Nova Tech collected and screened 19 key sustainability topics to determine the level of economic, environmental, and social concerns of the domestic engineering industry, and distributed questionnaires for analysis, ranking, and consolidation.
In 2023, the results of this survey will be continued, and Nova Tech will compare the key sustainability topics with the industry trends and issues of interest to its benchmarking peers in 2023, and examine the development of company issues. Taking into account the development of the company's issues, NovaTech identified 13 key sustainability themes (one new theme from last year) that are used as the basis for the compilation and disclosure of this Sustainability Report. The screening process for 2022 is described below:
