國(guó)際計(jì)量局局長(zhǎng)安妮特·古和國(guó)際法制計(jì)量局局長(zhǎng)安東尼·唐納倫2026年世界計(jì)量日聯(lián)合致辭

每年，“世界計(jì)量日”都為我們提供了審視計(jì)量在社會(huì)發(fā)展中的關(guān)鍵作用的契機(jī)，以及推動(dòng)全球測(cè)量結(jié)果可信可比、廣泛可靠的國(guó)際合作。

在紀(jì)念《米制公約》簽署150周年這一里程碑之年過(guò)后，2026年世界計(jì)量日繼續(xù)引領(lǐng)我們放眼未來(lái)。本年度主題“計(jì)量：建立信任的基石”，直接闡明了科學(xué)、治理與公信力之間的內(nèi)在關(guān)聯(lián)，也彰顯了計(jì)量領(lǐng)域默默耕耘、為科學(xué)決策提供堅(jiān)實(shí)支撐。

測(cè)量何以成為建立信任的基石

可靠的測(cè)量數(shù)據(jù)，是政策制定者應(yīng)對(duì)各類(lèi)復(fù)雜挑戰(zhàn)的依據(jù)，無(wú)論是守護(hù)公眾健康、保障公共安全，還是統(tǒng)籌能源系統(tǒng)、開(kāi)展環(huán)境監(jiān)測(cè)、維護(hù)日常市場(chǎng)交易，都離不開(kāi)精準(zhǔn)計(jì)量。當(dāng)數(shù)據(jù)準(zhǔn)確、可比且可溯源，決策方能更清晰、更可信賴(lài)。

測(cè)量不僅要具有科學(xué)嚴(yán)謹(jǐn)性，更需在清晰、規(guī)范的法律框架下實(shí)施，才能進(jìn)一步夯實(shí)信任根基?？茖W(xué)計(jì)量保障測(cè)量結(jié)果準(zhǔn)確、跨境可比；法制計(jì)量確保測(cè)量在實(shí)踐中統(tǒng)一公正實(shí)施。二者協(xié)同發(fā)力，推動(dòng)政策目標(biāo)轉(zhuǎn)化為惠及公共利益的務(wù)實(shí)舉措。

測(cè)量在制定政策中的實(shí)踐

計(jì)量對(duì)政策的影響，在醫(yī)療健康等領(lǐng)域尤為凸顯。例如新冠疫情期間，全球各國(guó)計(jì)量實(shí)驗(yàn)室通力協(xié)作，為病毒檢測(cè)、防護(hù)裝備及疫苗研發(fā)提供可靠測(cè)量支撐。依靠可比、可溯源的測(cè)量數(shù)據(jù)，政府衛(wèi)生健康部門(mén)能夠在關(guān)鍵時(shí)期研判風(fēng)險(xiǎn)、評(píng)估成效、科學(xué)施策。

同樣，長(zhǎng)期環(huán)境監(jiān)測(cè)亦依賴(lài)可信的測(cè)量數(shù)據(jù)?；趪?guó)際可比的大氣、水質(zhì)及污染物監(jiān)測(cè)數(shù)據(jù)，各國(guó)政府部門(mén)能夠有效研判長(zhǎng)期態(tài)勢(shì)，為制定保障公眾健康、守護(hù)自然資源的政策奠定堅(jiān)實(shí)基礎(chǔ)。若對(duì)測(cè)量方法與數(shù)據(jù)比對(duì)缺乏信心，相關(guān)決策將失去穩(wěn)固根基。

計(jì)量亦是質(zhì)量保障與市場(chǎng)公平交易的重要支撐。以食品安全為例，計(jì)量體系有效提升了各國(guó)對(duì)食品污染物、殘留物質(zhì)及營(yíng)養(yǎng)成分的檢測(cè)能力，幫助政府監(jiān)管部門(mén)和生產(chǎn)企業(yè)證明產(chǎn)品符合既定的標(biāo)準(zhǔn)規(guī)范。

與此同時(shí)，法制計(jì)量框架為加油機(jī)、水表、電表等商用計(jì)量器具的準(zhǔn)確可靠運(yùn)行提供保障。計(jì)量器具依法依規(guī)接受監(jiān)管，既能有效增進(jìn)經(jīng)營(yíng)者與消費(fèi)者之間的互信，也能進(jìn)一步提升公眾對(duì)政府部門(mén)的信賴(lài)與認(rèn)可。

以合作凝聚信任

歸根結(jié)底，計(jì)量為政策制定提供科學(xué)依據(jù)，為社會(huì)治理構(gòu)建制度保障，并支撐經(jīng)濟(jì)社會(huì)穩(wěn)定。當(dāng)測(cè)量結(jié)果可靠、應(yīng)用規(guī)范統(tǒng)一，信任便會(huì)超越數(shù)據(jù)本身，延伸至依托測(cè)量數(shù)據(jù)的各類(lèi)機(jī)構(gòu)、各項(xiàng)協(xié)議與各類(lèi)決策之中。

值此世界計(jì)量日之際，我們誠(chéng)邀全球計(jì)量界同仁，深刻審視可信的測(cè)量在科學(xué)決策中的重要作用，并使得這一信任成為可能的合作和共同承諾。

期待與各界同仁共慶5月20日世界計(jì)量日！

Each year, World Metrology Day offers an opportunity to reflect on the essential role measurement plays in society — and on the cooperation that allows measurements to be trusted, compared and relied upon world-wide.

Following a landmark year celebrating 150 years of the Metre Convention, World Metrology Day 2026 invites us to look forward. This year’s theme, Metrology: building trust in policy making, speaks directly to the relationship between science, governance and public confidence, and to the quiet work that enables decisions to be made with assurance.

Why measurement matters for building trust in policy making

Reliable measurements provide the evidence policymakers depend on when addressing complex challenges — from protecting public health and ensuring safety, to managing energy systems, monitoring the environment and supporting everyday market transactions. When data is accurate, comparable and traceable, decisions can be taken with greater clarity and confidence.

Trust is strengthened further when measurements are not only scientifically sound, but also applied within clear and predictable legal frameworks. Scientific metrology ensures that measurements are accurate and comparable across borders; legal metrology ensures that they are applied consistently and fairly in practice. Together, they help translate policy objectives into practical provisions that serve the public interest.

From measurement to policy in practice

The impact of metrology on policy can be seen clearly in areas such as healthcare. During the COVID-19 pandemic, for example, metrology laboratories around the world worked to support reliable measurements for testing, protective equipment and vaccine development. Comparable and traceable data enabled health authorities to assess risks, evaluate performance and act on evidence at a critical moment.

Similarly, long-term environmental monitoring relies on trusted measurements. Internationally comparable measurements of atmospheric gases, water quality and pollutants underpin the data used by authorities to track trends over time and to design policies that protect health and natural resources. Without confidence in how these measurements are made and compared, such decisions would lack a stable foundation.

Metrology also underpins quality assurance and fair market practices. In food safety, for example, metrology programmes have strengthened countries’ ability to measure contaminants, residues and nutritional content, helping authorities and producers demonstrate that products meet agreed specifications.

In parallel, legal metrology frameworks help ensure that measuring instruments used in commerce, such as fuel dispensers, water meters and electricity meters, perform as expected. When instruments are subject to appropriate legal control, trust is strengthened not only between producers and consumers, but also between public authorities and the communities they serve.

Trust built through cooperation

Ultimately, metrology underpins the evidence that informs policy, the frameworks that protect society, and support economic and social stability. When measurements are reliable and consistently applied, trust extends beyond data — to the institutions, agreements and decisions that rely on them.

This World Metrology Day we invite the global metrology community to reflect on the role trusted measurements play in shaping decisions, and to recognise the cooperation and shared commitment that make this trust possible.

We look forward to celebrating with you all, on 20 May!
