2024年5月20日是第25個“世界計量日”，國際計量局（BIPM）和國際法制計量組織（OIML）發布了2024年“世界計量日”全球主題——“Sustainability”。市場監管總局將“世界計量日”全球中文主題正式確定為“可持續發展”，“世界計量日”中國特別主題正式確定為“計量筑基新質生產力，促進可持續發展”。以下為國際計量局（BIPM）與國際法制計量局（BIML）局長聯合致辭（中英文版）——我們今天的測量，是為了可持續發展的明天（We measure today for a sustainable tomorrow）。
世界計量日——2024年5月20日
World Metrology Day - 20 May 2024
我們今天的測量，是為了可持續發展的明天
We measure today for a sustainable tomorrow
計量，即測量的科學及其應用，一直處于科技進步的前沿。它的影響可見于社會的方方面面，存在于生活的點點滴滴。
Metrology, the science of measurement and its application, has always been at the forefront of technological and scientific advancements. Its impact can be seen in all aspects of society and it is omnipresent in our lives.
今年，世界計量日的主題是“可持續發展”。準確的測量是環境研究和政策制定的基礎，因為它使我們有能力了解和應對復雜的環境挑戰，如氣候變化、污染和資源枯竭。可持續發展的主題鼓勵我們探索計量如何改善我們的日常生活。例如，準確可靠的測量有助于更好地監測環境參數，更好地評估人類活動影響，更好地制定促進生態平衡戰略。計量還使我們能夠作出明智的決策，無論是通過量化碳排放，測量廢棄物，還是監測自然棲息地。
This year, the theme for World Metrology Day is sustainability. Accurate measurements are the basis of environmental research and policymaking because they enable us to understand and tackle complex environmental challenges such as climate change, pollution, and resource depletion. The theme of sustainability encourages us to explore how metrology contributes to improving our lives every day. For example, accurate and reliable measurements enable better monitoring of environmental parameters, better assessment of the impact of human activities, and the development of strategies that promote ecological balance. Metrology empowers us to make informed decisions, whether by quantifying carbon emissions, measuring waste, or monitoring natural habitats.
計量在碳核算中發揮著至關重要的作用。碳核算涵蓋廣泛的活動，包括污染物的精確測量、計算、監測、報告和核查。碳核算方案和其他保護環境的監管措施需要可靠的數據，其基于對環境中潛在的十億分之一水平的污染物的準確測量。
Metrology plays a critical role in carbon accounting, which can cover a wide range of activities including the accurate measurement, calculation, monitoring, reporting, and auditing of pollutants. Carbon accounting schemes and other regulatory measures for safeguarding the environment require reliable data, based on the accurate measurements of pollutants potentially present in the environment at part per billion levels.
計量的重要性還體現在它支持聯合國可持續發展目標（SDGs）和聯合國為實現可持續的全球發展所做的各種努力，包括：
Metrology is also of key importance because it supports the Sustainable Development Goals (SDGs) and the efforts of the United Nations in achieving sustainable global development:
· 以法制計量為基礎的公平、透明的貿易，能夠改善所有人的經濟狀況，有助于減少貧困；
· fair and transparent trade based on legal metrology serves to improve economic conditions for us all and assists in reducing poverty;
· 可靠和可比的測試結果，對于增進我們的健康和福祉至關重要；
· reliable and comparable test results are important in order to improve our health and well-being;
· 有效地應對氣候變化行動，必須以能夠量化排放量、監測基本氣候變量、監控減排策略有效性的測量技術為基礎；
· effective climate action must be based on measurement technologies that quantify emissions and essential climate variables as well as monitor the effectiveness of mitigation strategies;
· 測量對于開發和監測清潔能源技術至關重要，這些技術保證了我們能夠獲得負擔得起的清潔能源；
· measurements are essential in order to develop and monitor the technologies that ensure we have access to affordable and clean energy; and
· 工業創新和基礎設施，依賴于對各種參數的準確測量。
· industrial innovation and infrastructure depend on accurate measurements for a wide range of parameters.
2024年的世界計量日主題強調了計量在所有這些情況下發揮的關鍵作用，并提醒我們有保護地球的共同責任。
The theme for World Metrology Day in 2024 underscores the pivotal role that metrology plays in all these cases and reminds us of our collective responsibility to safeguard our planet.
今年也標志著世界計量日推廣工作的新篇章，因為2023年11月召開的聯合國教科文組織（UNESCO）第42屆大會通過決議，正式認可每年5月20日的世界計量日慶祝活動。這將為宣傳計量提供新的契機，它也與聯合國教科文組織“通過科學和教育建設更美好世界”的使命相吻合。
This year also marks a new chapter in the promotion of World Metrology Day following the Resolution adopted by the 42nd Session of the UNESCO General Conference in November 2023 to grant official recognition by UNESCO to its celebration on 20th May each year. This will provide new opportunities to promote metrology, and aligns with UNESCOs mission to construct a better world through science and education.
