继6月28-6月29日的破冰与组队环节之后，可持续发展马拉松项目Hack2的参与者在环境学院师生团队的帮助下，于接下来的5天内陆续完成了听取主旨演讲、头脑风暴、问题调研、阶段性汇报等活动环节，并于7月5日进行了Hack2的最终汇报。针对多样的环境问题，12支队伍各自展示了自己颇具创意的解决方案，其中由Choi Pak Yin等6位同学组成的Tesla M队斩获了Hack2的杰出团队奖，并代表Hack2在总会场做精彩展示。
Following the ice-breaking and team formation sessions from 28 to 29 June, participants of the SDG Hackathon Hack2 completed keynote speeches, brainstorming, problem research and cross pitches over the next five days with the help of a team of students and faculty from the School of Environment, and presented in the Hack2 final report on 5 July. Each of the 12 teams showed their creative solutions to a variety of environmental problems, as the Tesla M team, consisting of six students led by Choi Pak Yin, won the Hack2 Outstanding Team Award and represented Hack2 in the final presentation.
主旨演讲
Keynote speeches
6月29日晚与6月30日晚，来自环境学院的李金惠老师、侯德义老师、左剑恶老师和鲁玺老师分别就构建零废弃物城市、应对土壤污染、污水处理和大气污染防治四个领域做了主旨演讲。学生们即从中积累了环境领域的基础知识，也通过和老师的问答讨论激发了后续项目的灵感。
On the evenings of 29 June and 30 June, Prof.Li, Jinhui, Prof. Hou, Deyi, Prof. Zuo, Jianxiao and Prof. Lu, Xi from the School of Environment gave keynote speeches regarding four fields: zero-waste city, soil pollution, wastewater treatment and air pollution. The students gained basic knowledge in the field of environment from the lectures and were inspired by the Q&A sessions with the teachers for their subsequent projects.
小组讨论与阶段性汇报
Group discussion and cross pitches
6月30日-7月4日是同学们开展小组讨论，明确思路和打磨方案的重要时间段。在这几天中，同学们不但要在小组协作时克服时差等线上交流带来的障碍，还要在7月1日和7月3日两天完成两次阶段性汇报。在各小组的头脑风暴中，起初模糊的想法逐渐成型，并在两次阶段性汇报中得到了导师们的指点，逐渐完善成具体可行的方案。
The period from 30 June to 4 July was an important time for the students to work in groups, clarify their ideas and polish their proposals. During these days, students not only had to overcome barriers including time difference in online communication when working in groups, but also had to complete two cross-pitches on 1 July and 3 July. During the brainstorming sessions, the initial vague ideas were gradually shaped and refined into concrete and feasible solutions with suggestions from the teachers during the two cross-pitches.

学员感想：
Reflections of participants:
Choi Pak Yin：The most exciting part of the Tsinghua GSS is the SDG Hackathon. My teammates come from a very culturally diversified background, while some of them believe in the power of social innovation and some of them believe that the government should take the lead in environmental protection. With all these great ideas coming together, we have figured out a solution that would enhance the engagement of various stakeholders. Thank you, Tsinghua, for hosting this amazing event!
Jorge Enrique Ascencio Damian: Through this Hackathon, I learned a lot of things, especially about the SDGs, and why they are important for our society and future. In the Hackathon I also got the opportunities to work with other international students and propose a sustainable solution towards an environmental problem that is affecting our world. I’m looking forward to applying all the knowledge I got to the benefits of our society. Thank you!
最后，感谢各位老师和同学对本次活动的关注和参与对本次活动的大力支持。可持续发展背景下的环境保护是人类社会在21世纪最为重要的话题之一，希望每一个关注环境问题的人能开动创意，提出更多富有创造力的解决方案，并通过行动真正地为环境保护事业做出贡献。
Finally, We would like to thank all the teachers and students for their interest and participation in this event. Environmental protection under the context of sustainable development is one of the most important topics for human society in the 21st century. We hope that everyone who is concerned about environmental issues can be creative, come up with more innovative solutions and make a real contribution to the cause of environmental protection through their actions.
