2024年5月20日是第25個“世界計量（liàng）日”，國際計（jì）量局（jú）（BIPM）和國際法製計量組織（OIML）發布了2024年“世界計量日”全球主題——“Sustainability”。市（shì）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（liàng）日”中國特（tè）別主題正式確定為“計量築基新質生（shēng）產力，促進可持續發展”。以下為國際計量局（BIPM）與國際法製計量局（BIML）局長聯合致辭（中英文版（bǎn））——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（chí）續發展的（de）明天
We measure today for a sustainable tomorrow
計量，即測量的科學及其應用，一（yī）直處於科技進（jìn）步（bù）的前沿。它的影響可見於社（shè）會的方方麵麵，存在於生活的點點滴滴。
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（xù）發展”。準確的測量是環（huán）境研究和政策製定的基礎，因為它使我們有能力了解和（hé）應對複雜的環境挑戰，如氣候變（biàn）化、汙染和資源（yuán）枯竭。可持續發展的主題鼓（gǔ）勵我們探索計量如何改善我（wǒ）們的日（rì）常生活。例如，準確可靠的（de）測量有助於更好地監（jiān）測環境參數，更好（hǎo）地評估人類活動影響，更好地製（zhì）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（cè）量廢（fèi）棄物，還（hái）是監（jiān）測自然棲息地（dì）。
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（fā）揮著至關重要的作用。碳核算涵蓋廣泛的活動，包括汙染（rǎn）物的精確測量、計（jì）算、監測、報告和核查。碳核（hé）算方案和其他保護環境的監管措（cuò）施需要可靠的數據（jù），其基於對環境中潛在的（de）十億分之（zhī）一水平的汙染物的（de）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（xìng）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（chí）續的全球發展所（suǒ）做的各種努力，包括（kuò）：
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:
· 以法製計量為基礎的公平、透明的貿易，能夠改善所有人的經（jīng）濟狀況，有助於減少貧困（kùn）；
· 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，對於增（zēng）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（dì）應對氣候變化行動，必須以能夠量化排放量、監測基本氣（qì）候變量、監控減排策略有（yǒu）效性的測（cè）量技術為基礎（chǔ）；
· 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（duì）於開發和監測清潔能源技術至關（guān）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，依賴於對各種（zhǒng）參數的（de）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（liàng）日主題強調（diào）了計量在所有這些情況下發揮的關鍵作用，並提醒我們有保護地球（qiú）的共同（tóng）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.
今年也標誌著世界計量日推廣工作的新篇章，因為2023年11月（yuè）召開的聯合（hé）國教科文組織（UNESCO）第42屆大會通過決（jué）議，正式認（rèn）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（kē）學和教育建設更美（měi）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.
