    副行长关于金融支持碳达峰、碳中和主题演讲稿

    第一,知行合一,切实提高绿色低碳转型的思想自觉和行动自觉。要有全面、系统、深刻认识“30·60”内涵的思想自觉。与发达国家相比,我国仍处于快速工业化、城镇化进程,经济将在较长一段时期保持中高速增长,人均能源需求尚有较大上升空间,未来碳减排压力较大。据国际组织、科研机构测算,我国碳排放峰值将超过XXX亿吨,而XX碳排放峰值为XX亿吨,XX约为XX亿吨。我国从碳达峰到碳中和仅有XX年时间,远低于欧XX家XX-XX年的时间。“碳达峰、碳中和”不是要简单以牺牲经济增长速度、国民财富积累和人民生活水平提高为代价,而是要实现碳减排约束下全面、协调、可持续的高质量发展,需要充分、理性、智慧地平衡好生态文明建设与经济社会发展的关系。未来几十年,绿色低碳转型将嵌入所有经济活动的内核,成为投资、生产、消费和流通等决策的核心逻辑。

  • 国旗下的讲话稿:社会主义核心价值观记心中

    国旗下的讲话稿:社会主义核心价值观记心中

    尊敬的老师、亲爱的同学们: 早上好!我今天演讲的主题是:《社会主义核心价值观记心中》。同学们,你们知道什么是社会主义核心价值观吗?那就是富强、民主、文明、和谐;自由、平等、公正、法治;爱国、敬业、诚信、友善。那么我们小学生要怎样践行核心价值观呢?当我们发现地上有废纸时,要主动把它捡起,放进垃圾箱;当发现有同学乱扔垃圾、践踏草地时,我们要及时阻止

  • 国家宪法日国旗下讲话稿:宪法在我心中

    国家宪法日国旗下讲话稿:宪法在我心中

    尊敬的各位老师,亲爱的同学们:大家早上好!今天我讲话的题目是“宪法在我心中”。在社会这个大家庭里,我们每个人如何约束自己、规范自己的行为呢?那就是——“法”。它是我们每个人明确是非的界限,这也是我们每个公民所应具备的最基本的素质。12月4日,是中国的“宪法日”。之所以确定这一天为“宪法日”,是因为中国现行的宪法在1982年12月4日正式实施。宪法是国家的根本大法,中华人民共和国宪法主要包括序言,总纲、公民的基本权利和义务、国家机构和国旗、国歌、国徽、首都四章。它保障国家权力有序运行,规范和制约国家权力;确认和保障公民基本权利;调整国家最重要的社会关系,维护社会稳定和国家长治久安。XX年全国人大常委会设立每年12月4日为国家宪法日。法律对我们小学生来说,可能只是一个神圣而又模糊的名词。法律是一件安全的外套。从我们出生开始,法律就对幼儿、小孩受教育、婚姻、生命财产不受侵害、社会医疗保障、老年抚养等等都作了明确的规定,同时还特别在1991年制定通过了未成年人保护法,对未成年人健康成长的保障进行了完善。法律的保护让我们快乐地成长,幸福地生活。法律是行动的指针。像我们开口不能骂人,伸手不能打人一样,我们的言行都要受到法律的约束,同时也受到法律的保护。大人们每做一项工作,每签一个合约,都要涉及很多法律条款,法律使社会运行有序,人们和谐相处。

  • 关于初中学生端午节在国旗下讲话演讲稿

    关于初中学生端午节在国旗下讲话演讲稿

    老师们、同学们!端午节,门插艾,香满堂,吃粽子,洒白酒,龙舟下水喜洋洋。这些,都是曾经端午节上最热闹的活动,然而,随着时代的变迁,社会节奏的加快,外来文化的大举入侵,中国人不再眷顾流传几千年的中国传统文化,而是将目光转向了“圣诞节”“愚人节”这样的节日,面对这种现状,我们不得不感到悲哀,发出“端午节是否不再姓“中”这样的疑问。当我们还沉浸在西洋节日的欢声笑语中时,据可靠消息说“亚洲某国准备向联合国教科文组织申报端午节为本国的文化遗产,目前已将其列入国家遗产名录。听到这种消息,中国人除了惊讶只有尴尬,这不仅仅是一个传统节日的得失,不仅仅是少了几项庆祝活动,更重要的是,这是中国的传统节日,文化内涵丰富,留存着华夏民族独特的文化记忆,每过一次传统节日,就是中华民族凝聚力和向心力的一次加强和洗礼,如今,这个拥有XX多年历史的传统佳节眼瞅着即将成为他国的国家遗产,我们将有多么尴尬?

  • 关于安全的国旗下讲话稿 安全常系心中

    关于安全的国旗下讲话稿 安全常系心中

    谢谢大家!尊敬的各位老师、亲爱的同学们:大家好!今天我讲话的题目是《安全常系心中》。你们知道生活中什么最重要吗?是安全。只有保证我们生命和生活的安全,一切才有意义。当同学们听到有关小学生意外伤害事故时,不知道你们想了些什么。我想,同学们至少会想到:这些教训无论发生在谁的身上都会给受害者人身造成伤害、甚至死亡;会给受害者家庭造成极大的损失;会给学校正常教学秩序造成混乱;会给社会造成不稳定影响。安全问题关系到我们每一位学生的切身利益,只有安全才能为我们保驾护航。在这里,我向全体同学发出倡议:1、校内课间不追逐打闹,上下楼梯慢步轻声,靠右行。2、放学按时离校,不在校园内逗留。3、不到小摊小贩购买食物,不吃不洁食物,喝水要讲究卫生,注意身体健康。4、保证用电安全,不乱动电源插座。
