It has been six years since Hua Nan Financial Holdings prepared its first CSR report in 2014. As the first financial holding company established in Taiwan, it has operated the century-old Hua Nan Commercial Bank (HNCB), which was founded in 1919. With a century of experience, we have learned and thought about the fulfillment and direction of corporate social responsibility with the world. We have not only maintained communication and interaction with stakeholders, including the government, shareholders, customers, employees, suppliers, and the general public to understand each stakeholder's expectations of the Group, but also we are moving toward the goal of corporate sustainable development.
We pay close attention to the development and initiatives of international CSR in recent years to strengthen the strategic blueprint for the Company's sustainable development. In 2019, a letter from shareholders suggested that we pay attention to climate change issues, disclose relevant risks identified, and formulate strategies to respond. To this end, we have responded to the Carbon Disclosure Project (CDP), based on which we plan to introduce Task Force on Climate-related Financial Disclosures (TCFD) gradually to establish a risk management and control mechanism on climate change, and we will examine the three major aspects of the environment, society, and corporate governance (ESG), while constantly adjusting our pace to cope with future operational risks, in the hope of gaining insights and grasping the opportunities that arise with risks.
The stable development of our core business is the driving force behind the continuous progress of Hua Nan Financial Group. Looking back on 2019, the financial performance of the Group had grown steadily, with consolidated net income after tax of NT$15.955 billion, a 9% increase from the previous year, and the earnings per share (EPS) was NT$1.31. As for non-financial performance, the results are equally impressive. The Group has continued to be selected as a constituent stock of the FTSE4Good Emerging Index, the FTSE4Good TIP Taiwan ESG Index, the TWSE Corporate Governance 100 Index, the Taiwan HC 100 Index, and the TWSE RA Taiwan Employment Creation 99 Index. In 2019, Hua Nan Financial Holdings won the Gold Sponsorship, Long-term Sponsorship, and Promotional Bronze Awards at the 2019 Sports Contribution Award again, which have all indicated that the Group's performance in ESG has been highly recognized by professional institutions at home and abroad.
Meanwhile, how to respond to environmental issues through the core business and to pursue a sustainable new economic model are the goal the Group strives toward through continuous improvement and learning. The subsidiary HNCB has followed the spirit of the Equator Principles since 2017 and has completed the formulation of the Sustainable Credit Principles and the Negative List in May 2019 to strengthen the integrity of ESG risk assessment. Secondly, the Green Energy Technology Financing Promotion Team has been formed to integrate internal resources, continue to develop green energy technology financing business, and cooperate with foreign banks, green energy technology businesses, and local governments, to expand green finance business opportunities. As of the end of 2019, the total balance of credit granted to the green energy technology, new agriculture, and circular economy industries was NT$297.6 billion, of which the balance of credit to the circular economy reached NT$185.4 billion.
In addition, the head office building of HNCB has obtained certification of the ISO 14001 environmental management system and the ISO 14064-1 greenhouse gas inventory for four consecutive years since 2016. In 2018, it also obtained certification of the ISO 50001 energy management system. In order to track and analyze the Group's greenhouse gas emissions more comprehensively and reduce impact on the environment, we expanded the scope of our greenhouse gas inventory to 30 branches of HNCB in 2019, and in 2020 the scope of our inventory will be expanded to 186 branches in Taiwan. Hua Nan Financial Group expects to lead corporate clients to face up to the impact of corporate operations on the environment and society through its financial influence, and to go on a journey to sustainable development with its customers.
As a member of the financial industry, Hua Nan Financial Holdings shoulders the important responsibility for supporting the development of the industry, bringing positive benefits to the society through its professional financial services, and striding forward with the society when making profits. In the future, while formulating relevant strategies in the face of emerging risks, we will remain committed to bringing profits to shareholders and protecting the wealth and assets entrusted by customers in the changing situation, while complying with the government's regulations and standards so as to accompany everyone who trust Hua Nan through our professionalism and integrity. "Safeguarding your original intention" is a specific demonstration of our step-by-step implementation of CSR.
