減輕香港氣候風險對吸引人才至關重要:第 1 部分 – 交通運輸

香港地球之友綠色金融顧問

在其他條件相同的情況下,人們更喜歡生活在氣候穩定的地方。特別是年輕一代希望保護他們未來所依賴的星球,氣候變化和環境管理已成為企業、城市和國家吸引和留住人才的關鍵因素。儘管作出了 2050 年碳中和承諾,但香港特別行政區政府仍缺少實現目標的詳細路線圖、政策和財政支持。

根據最新的政府報告,2020 年香港 80% 的排放來自兩個領域——電力和能源行業以及交通運輸[1]  。在 COVID 之前,來自這兩個排放源的排放份額甚至更高,達到 84%。香港如何獲取能源和管理交通系統是其脫碳的關鍵考慮因素。遺憾的是,這兩個領域都只取得了一點進展。正如香港地球之友對 2022 年政策的回應中指出,我們缺乏政府強而有力的氣候政策來幫助香港適應和減輕氣候風險。

自 2015 年以來,來自交通運輸的總氣體排放量並沒有顯著增長。事實上,有人可能會爭辯說,交通運輸的氣體排放已經在 90 年代後期達到頂峰。我相信對這種排放穩定性的主要貢獻是來自我們的鐵路系統。鐵路載客量佔公共運輸總載客量約41%,但僅貢獻了運輸排放量的 3%。相比之下,作為主要客運排放源的私家車和摩托車佔我們運輸排放量的 24%。巴士和的士分別貢獻了 21% 和 16%[2]

港鐵沙中線已通車,我們預期會有更多乘客轉乘鐵路進行日常交通。這反過來將有助於減少總排放量。 港鐵仍有空間擴展其網絡。然而,由於我們的鐵路網絡已經覆蓋了我們大部分的人口。未來港鐵鐵路項目對減排的邊際影響會逐漸減弱。減排的負擔顯然落在了交通系統的其他部分。

我們很高興看到更多人駕駛電動汽車或混合動力汽車,但柴油巴士和石油氣的士的運行是現行香港氣候風險的主要製造者。為了使巴士脫碳,政府需要推動向由電力和綠色氫驅動的巴士過渡。此外,政府與巴士運營商多年來一直在討論的巴士路線重組應加快推進。優化道路交通可以顯著減少運輸上的氣體排放。

的士在人口稠密地區的減排中發揮著關鍵作用。在新加坡,的士公司已率先承諾在 2040 年或之前使用百分百清潔能源汽車。[3] 香港政府至少應考慮設定有時限的目標,將所有的士轉換為電動汽車或混合動力汽車。低排放也應作為未來的士和其他車輛出牌或續牌的要求。

貨運是我們需要削減排放的另一個領域。商業環境委員會今年早些時候發布了一份關於該領域脫碳的報告[4]。我建議香港政府認真考慮和落實報告中提出的建議。

出於篇幅考慮,我將在另一時間討論電力和能源行業在香港的碳足跡。

Mitigating Hong Kong Climate Risks is Important to Attract Talent: Part 1 – Transport

Green Finance Advisor of Friends of the Earth (HK)

All other things equal people prefer to live in an environment with stable climate. In particularly, the younger generation wants to preserve the planet where their future depends on. The management of climate change and environment has become a key factor for companies, cities and countries to attract and retain talents. Despite making the 2050 carbon neutrality commitment, the Hong Kong SAR government is missing a detailed roadmap, policies, and financial support to achieve the goal.

Based on the latest government report, 80% of Hong Kong emissions in 2020 came from two areas – power & energy industries and transportation. [1]  Before COVID, the share of emission coming these areas was even higher at 84%. How Hong Kong sources its energy and manages its transportation system are key considerations of its decarbonization. Sadly, only a little progress has been made in both areas. As pointed out in the Friends of the Earth (HK) Response to the 2022 Policy, there is a lack of strong climate policies from the government to help Hong Kong adapt and mitigate climate risks.

The total emission coming from transport has not been rising much since 2015. In fact, ones may argue that transport emissions already peaked in the late 90s. I believe a major contribution to this emission stability is our reliance on railways, which deliver 41% of all trips on public transport of the city but contributed only 3% of its transport emissions. Comparatively, private cars and motorcycles, the major passenger transport emitters, generated 24% of our transport emission. Buses and taxi contributed another 21% and 16% respectively.[2]

Following the commencement of the MTR Sha Tin to Central Link earlier this year, we could expect more passengers to switch to railways for daily transport. This in turn will help reduce the overall emissions. There remains room for MTR to expand its network. However, since our railway network has already covered majority of our population. The marginal impact for future MTR railway projects to emission reduction is likely to taper off.

The burden for emission cuts clearly goes to the rest of the transportation system. We are glad to see more people driving electric cars or hybrid vehicles but the running of diesel-fuelled buses and LPG-powered taxis is a primary builder of climate risks of Hong Kong. To decarbonize buses, the government needs to drive the transition to buses powered by electricity and green hydrogen. In addition, the bus route rationalization, which has been discussed for many years between the government and bus operators, should speed up. Transport emissions can be materially reduced when road traffic is optimized.

Taxi plays a critical role in emission cuts in densely populated areas. In Singapore, taxi companies have taken lead to commit to 100% cleaner energy vehicles by 2040.[3]  To the minimum the Hong Kong government should consider setting time-bounded targets for conversion of all taxi to electric vehicles or hybrid vehicles. Low emissions should also be included as a criteria in the new license application and license renewal of taxi and other vehicles.

Freight transport is another area we need to slash emissions. The Business Environment Council earlier this year published a report about decarbonization of this segment.[4] I recommend the Hong Kong government to seriously consider and implement suggestions given in the report.

In the interest of space, I will discuss about the carbon footprint of our power & energy industries in another time.

ESG投資講就天下無敵,實際還是有心無力?

香港地球之友綠色金融顧問黃思靈

英國投資顧問公司Redington在9月27日發表了一篇研究報告, 指43%的受訪投資經理無法提供過去12個月裡由於ESG原因而作出有關賣出決定的例子,35%的回覆人士未能證明因ESG動機而作出買入決定。雖然一直都說全球都越來越重視ESG議題,鼓勵ESG投資,但這報告似乎狠狠的說明了ESG投資還沒有想像中成熟。

是次調查訪問了122名來自不同地方的投資經理,他們代表著接近40萬億美元的資產。 98%的投資經理表示工作機構有企業的ESG政策,80%已有專門的團隊或者人員負責ESG投資事宜;超過一半回覆單位都至少為僱員每年進行一次ESG相關培訓。一切聽起來都很理想,只是實際上把ESG真正放到投資考量時,力度還是讓人失望。

10月6日Morningstar刊登的調查報告也有類似的結論,訪問了500名環球資產所有者,當中只有29%被訪者有把ESG因素放到一半以上的資產投資決定裡面去,就是說大概70%的資產所有者沒有在作他們大部分的投資決定時考慮到ESG。 ESG投資可能帶來負回報是受訪人士最大的憂慮,說到底還是回報最重要。

但是大家不應該因此就覺得氣餒,筆者認為目前社會都還在ESG教育階段,ESG投資的價值不單純在金錢回報,目標是希望能把人類的生活變得更可持續,不要到最後把自己都毀滅掉。 ESG模式都還在發展中,現時鼓吹的做法也未必最有效。但只要大眾都能同意ESG的方向是對的,最後總能開拓出合適的方案。這些報告就是告訴我們目標還沒有達到,繼續努力吧~

Metaverse and ESG

【Idea Exchange】Andy Yiu, CESGA

Everybody talks about the Metaverse, but what exactly is the Metaverse? What does the Metaverse have to do with ESG? In recent months, I have attended the annual conference events of the Hong Kong Institute of Certified Public Accountants (HKICPA) and the Royal Institution of Chartered Surveyors (RICS) to share the latest developments in the Metaverse and its potential impact on the traditional professions. The first question I was always asked: what is the Metaverse?

The definition of the Metaverse varies, and its origin can be traced back to science fiction from decades ago. In my opinion, the Metaverse consists of the following three key elements: (1) immersive experience, (2) socializing activities, and (3) asset ownership. First of all, with the development of hardware technologies, such as data bandwidth and wearable devices, software and hardware applications of Extended Reality (XR for short, including AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality)) began to emerge. The cost is lower and more reasonable to retail users, reducing the threshold for mass adoption.

Second, it is about socializing activities. From the current online “play-to-earn” games to futuristic digital smart cities, the Metaverse focuses on improving the well-being and productivity of human society through the combination of virtual and physical worlds. Thirdly, it is the use of digital assets enabled by blockchain technology as an economic model to incentivize the development of the Metaverse. From Web1.0 era which transmission of information is one-way, to Web2.0 where large social platforms own all the user data, we are progressing towards a new economic model of Web3.0 that advocates the “creator economy”.

In the “14th Five-Year Plan”, the Chinese government lays down the plan to develop the digital economy. Key industries include blockchain, internet of things, virtual reality, and other essential components of the Metaverse. Since 2021, both the national and local government levels have announced their Metaverse-related development policies. To date, as many as 24 provinces and cities, including Beijing, Shanghai, Guangzhou, Wuhan, Chongqing, etc., have announced their Metaverse development policies.

Another major national policy of China is to achieve carbon peaking by 2030 and carbon neutrality by 2060. So, can the Metaverse technology help the grand goal of carbon reduction? In his book “How to Avoid a Climate Disaster”, Bill Gates emphasizes that everyone should have the chance to live a healthy and productive life. It is unethical and impractical to ask backward countries to give up using more energy to improve their lives. The solution should be to invest in breakthrough technologies to achieve carbon neutrality.

The use of blockchain and even metaverse technology to solve the climate crisis is no longer just a concept, and many business cases have already been implemented. The digital twin technology can model the whole process and perform sandbox simulations. For instance, it has been applied in the real estate industry for planning and design instead of making physical models, reducing carbon emissions. Singapore, Boston, and San Francisco have established city-level digital twins to analyze and plan urban development with real-time data, simulate policy effects, and strengthen risk management capabilities to respond to crises.

Cases in other countries include NFT trading platforms to facilitate peer-to-peer trading of renewable energy certificates and carbon credits. An Australian company called Power Ledger uses the blockchain decentralization technology to try to innovate the electricity trading market. For example, consumers can trace the source of electricity production through the immutable ledger on the blockchain, so that they can have a choice on clean energy. Its trading platform allows consumers to conduct P2P buying and selling of solar power. Another company in South Africa, The Sun Exchange, uses Bitcoin and other cryptocurrency technologies to promote third-party investment in solar panels, and lends electricity to local schools, retirement homes, and small and micro enterprises through its online micro-leasing marketplace. Investors earn interest income from it, borrowers obtain clean energy required for production, and the local environment achieves carbon reduction, achieving a win-win-win situation.

Earlier, I attended the HKUST 30th Anniversary Web3 Carnival, an alumni event of Hong Kong University of Science and Technology. In his keynote speech, Professor Yang WANG, Vice President of the university, pointed out that Hong Kong, as the most international city of China, should take advantage of “One Country, Two Systems” to become the sandbox and the bridge to the world for China’s digital economy and the development of the Metaverse. Hong Kong needs to develop the Web 3.0 digital economy as one of the key catalysts to address its own social issues. The vision is to establish “Metaverse Hong Kong” (MetaHK), striving to make Hong Kong a Metaverse-powered Smart City.

綠色元宇宙

【意見交流園地】姚樹誠, CESGA

潮流興講元宇宙,但究竟甚麼是元宇宙?元宇宙與ESG又有甚麼關係?筆者近月分別出席香港會計師公會(HKICPA)及皇家特許測量師學會(RICS)的年會活動,分享講解元宇宙的最新發展及對傳統專業的潛在影響。第一個必問的問題,甚麼是元宇宙?

元宇宙的定義言人人殊,典故可以追朔幾十年前的科幻小說。筆者認為元宇宙包含以下三項元素:(一)沉浸式體驗,(二)社交型活動,(三)資產擁有權。首先,隨著數據頻寬及可穿戴設備等硬件科技的發展,越來越多擴展現實(Extended Reality,簡稱XR,包含AR (增強現實)、VR (虛擬現實)、MR (混合現實))的軟硬件應用開始出現,使用成本開始可為零售用戶接受,降低廣泛推廣普及使用的門檻。

第二,社交型活動。從現時已能實現、多人線上“邊玩邊賺”(Play-to-earn)游戲,到展望將來的宏觀的數字城市,元宇宙講求的是通過虛實結合的方式,提升人類社會的福祉及生產力。第三,是利用區塊鏈技術實現的數字資產,作為激勵元宇宙發展的經濟模式。從Web1.0 單向式傳遞資訊,到大型社交平台擁有用戶資料的Web2.0,我們正逐步邁向推崇“創作者經濟”的Web3.0新經濟模式。

國家在《十四五規劃》中明確發展數字經濟,重點產業包括區塊鏈、物聯網、虛擬現實等元宇宙重要構成部分。從2021年開始,國家層面及地方政府,針對元宇宙相關產業的政策設計陸續推出。據統計,已經有多達24個省市,包括北京、上海、廣州、武漢、重慶等公佈了其元宇宙發展政策。

國家另一個重大政策是“雙碳”,即2030年前實現碳達峰、2060年前實現碳中和。那麼元宇宙科技又能否協助達至綠色減碳這個宏大目標呢?比爾蓋茨在其著作《如何避免氣候災難》中強調,每個人都應該有機會過上健康和富有成效的生活,而要求落後國家放棄使用更多能源改善生活是不道德及不切實際的。解決出路應該是投資突破性技術實現碳中和。

使用區塊鏈甚至是元宇宙科技以解決氣候危機已經不再只停留在概念上,不少案例已經落地進行。數字分身(Digital Twin)技術,可以對全環節建模仿真及沙盤推演,在例如房地產業已經開始應用,可以減少規劃設計時的碳排放。新加坡、波士頓及三藩市等城市甚至已經建立城市級別的數字分身,以實時數據分析規劃城市發展,模擬政策效果,強化城市風險應急能力。

其他外國的案例包括建立類似NFT交易平台,促進可再生能源證書及碳排權點對點交易。一家叫Power Ledger的澳大利亞公司,利用區塊鏈去中心化技術,嘗試創新電力交易市場,例如消費者可以通過區塊鏈上不可篡改賬本追查電力的生產來源,令其對潔淨能源有所選擇。其交易平台可以讓消費者進行P2P買賣太陽能電源。另一個在南非的公司The Sun Exchange,利用比特幣等加密貨幣技術,促進第三方投資太陽能電板,通過其線上微租貸平台向當地的學校、老人院、小微企等借出電力。投資者從中獲取利息收入,借貸方獲取潔淨能源拓展生產所需,當地環境實現碳減排,達至三贏。

筆者早前出席香港科技大學30週年校慶暨Web3嘉年華的校友活動,副校長汪揚教授致辭指出,香港作為中國最國際化的城市,應利用一國兩制的優勢,成為中國數字經濟和元宇宙發展連接世界的橋樑和沙盒。香港自身需要發展Web 3.0數字經濟,以其為解決社會問題的一個重要引擎。願景是建立“元宇宙香港”(MetaHK),力爭將香港打造成元宇宙智能城市。
