國際可持續公共採購的實踐與展望

[意見交流園地] 章逸飛博士(港大經管學院經濟學高級講師)、 江梓茵女士(港大經管學院本科生)、葉梓淇女士(港大經管學院本科生)

在2002年8月的可持續發展世界首腦會議上,可持續公共採購(Sustainable Public Procurement)概念首度被提出。此後,這一概念逐漸成為可持續生產和消費領域的關注焦點,並被納入公共採購制度的嶄新政策方向和推動全球可持續發展的重要實踐範疇。聯合國環境規劃署和聯合國經濟與社會事務部更將之視為馬拉喀什全球氣候行動夥伴關係(Marrakech Partnership for Global Climate Action)的關鍵一環。

何謂可持續公共採購?這是一種將環境、社會和經濟效益互相結合的採購策略,旨在通過政府採購活動促進可持續發展。傳統的公共採購主要集中在成本、品質和滿足需求,而可持續公共採購在此基礎之上,更強調環境、社會和經濟效益的平衡,使公營部門可以有效支援可持續發展目標,推動環境保護、社會福利和經濟增長。

在亞洲,日本於1992年率先推出《環保採購法例》,規定所有政府部門必須每年提交相關基本方針、預算和事項。每個採購決策都應建立在明確的數據標準上,以便提供客觀指標,可見日本對可持續採購非常嚴謹和重視。

市民的認同和支持,足令推行環保政策事半功倍。日本政府每年進行公眾諮詢,以便適當調整採購項目。例如當局曾經採購超過4萬個滅火筒,其中99.1%符合官方標準:滅火筒的液體至少40%符合再造物料成份的標準,經過完善的收集和處理流程,同時使用再造塑膠。採購完成後,政府會持續監管,透過追蹤每年符合標準的滅火筒數量,以檢討成效。通過這場大規模的環保公共採購,符合當局要求的滅火筒在本國市場佔比從2006年的46%上升至2013年的67.3%。

歐盟同樣是較早期就施行可持續公共採購,在2001至2010年期間,先後頒布了各項法例來完善制度,並給予成員國足夠靈活性,以致大部分成員國在2012年已經制定了相關條例和國家計劃。過半數成員國已落實可持續採購,當中德國、荷蘭和芬蘭表現最為積極。歐盟亦會以相關條例規範成員國實踐可持續採購。

在採購過程中,歐盟十分重視產品生命周期理念和分析方式,鼓勵廠家公開有關資訊。計算產品生命周期成本,有助於政府在兼顧環境和經濟效益的同時,避免只着眼於價格,而忽視生態效益顯著但初始成本較高的綠色產品或服務。

許多歐盟成員國政府部門都能成功運用產品或服務生命周期成本的概念。以德國漢堡為例,該市的環境部門決定以一個節能燈泡取代兩個普通燈泡的比例,替換所有燈泡。這一措施每年可減少45吉瓦時電力消耗,相當於減少2700噸二氧化碳排放。若每千瓦時電費節省5歐分,這個替換方案就可為漢堡節省22.5萬歐羅的電費開支。

可持續公共採購不僅帶來可量化的實際改變,也能對各個產業鏈產生潛移默化的影響。例如,希臘政府與7個地方政府聯合採購再生紙,再生紙的採購成本因而下降:每包500張紙的售價由2.9歐羅下降至2.34歐羅,減幅約為20%,進而帶動綠色市場的發展。因此,供應商不僅減少了有關開支,同時也提升了產品品質。從源頭推廣綠色產品,足以改變消費趨勢。減少廢物排放,自然也有利於社會環境和生態保護。

內地與香港的實踐經驗

中國政府近年致力於加大綠色低碳產品採購力度,並從建築業着手,提升全民的環保意識。鑑於目前全國建築全過程碳排放超過50億噸,佔碳排放總量一半,而材料的碳排放量尤甚。有見於此,財政部、住房和城鄉建設部、工業和信息化部於2022推出《關於擴大政府採購支持綠色建材促進建築品質提升政策實施範圍的通知》,在包括北京等48個市轄區實施政府採購政策,支持使用綠色建材,以促進建築品質。綠色建材具有節能、減排、安全、便利和可循環再用的優點,足以大幅減低建築時的自然能源消耗及其對生態環境的影響。各城市可先由部分項目開始施行,累計一定經驗後逐步擴大範圍,目標於2025年落實全國政府採購工程項目政策。

香港亦以促進環境保護和可持續發展為目標,積極推廣綠色採購,鼓勵在工務工程項目上使用可循環再造及環保材料。基於綠色材料成本可能高於傳統材料,政府要求各部門評估,並且替企業承擔因使用綠色材料而導致的額外成本,通過經濟誘因鼓勵企業予以採用。

在監管方面,特區政府訂定在工務工程項目中使用綠色材料的政策和指導原則,為採購流程提供了清晰的框架,並設跨部門工作小組,負責監督綠色規格的採用、審查常用產品和服務的採購,以及推廣綠色材料在工務工程項目中的使用。除此之外,當局採用了試用、早期實施階段和全面實施優先使用的3階段流程,確保新回收和其他綠色材料在技術上和在市場上的可行度。這一系列舉措不僅有利於減少廢物產生,還能推動企業採取更環保的生產和營運方式,從而提升其環境、社會及管治的表現。

企業作為政府可持續採購的供應商和合作夥伴,扮演着至關重要的角色。放眼未來,可持續公共採購可以使企業不斷推動綠色產品和服務的創新,以滿足政府部門在採購過程中對環保、節能、社會責任等方面的要求。這將惠及企業的競爭力,並為實現可持續發展目標作出貢獻。

為了滿足可持續採購的要求,企業將更加關注綠色供應鏈管理,確保其產品和服務在整個生命周期中盡量減少對環境和社會的影響。這包括對原材料、生產過程、運輸、銷售和回收等環節的全面考慮,以降低資源消耗和污染排放。隨着可持續公共採購理念的普及和政策推廣,企業將有機會拓展新的市場領域,包括綠色建築、節能交通和可再生能源等,既為企業帶來蓬勃商機,亦促進社會可持續發展,締造雙贏局面。

Justice for a Warming World: Climate Lawsuits Emerge as a Powerful Force

Green Finance Advisor of Friends of the Earth (HK)

Climate litigation, after years of development, is showing promising results globally, offering hope to climate activists that polluters might finally be held accountable.

In the United States, the Vermont case[1] represents a bold step towards holding fossil fuel companies financially responsible for climate damages. It seeks to recover costs for infrastructure damage, economic losses, and public health impacts caused by climate-related events.  Similarly, the Puerto Rico government filed a lawsuit alleging that the fossil fuel industry engaged in campaigns misleading consumers and the public about the impact of fossil fuel emissions.[2]  This lawsuit seeks compensation and remedies that could cost the oil and gas companies billions.  Notably, similar lawsuits against fossil fuel companies are filed in California, Connecticut, and other states.

A joint-staff report released in April 2024 by the US House Committee on Oversight and Accountability and the Senate Budget Committee exposed the fossil fuel industry’s deceptive commitments to reduce emissions.[3] The report, the culmination of a three-year investigation, uncovered misleading statements about the alleged climate safety of natural gas, false promises on new technologies, and obstruction of investigations.  These findings, alongside other documents, reveal that the oil and gas industry acknowledged the climate impact of fossil fuels as early as the 1950s[4], a stark contrast to the denial of major oil companies about climate change.

The evidence uncovered in the US investigation could strengthen climate litigation efforts not only domestically but also internationally. In Europe, the Paris Court of Appeal accepted a case brought by NGOs and local authorities against an oil company.[5] This case challenges the company’s failure to adequately report climate risks and take action to mitigate them, reversing a pre-trial decision to dismiss the case. This landmark case could pave the way for an unprecedented climate trial against the oil giant under the “Duty of Vigilance” law.  Additionally, this oil company faces other legal challenges, including a recent criminal case filed against its executives and directors.[6]  Individuals and NGOs argue that these executives, through their decision-making roles, are personally responsible for the company’s contribution to climate change and subsequent deaths caused by extreme weather events.

While the success of these climate lawsuits remains uncertain, they represent a powerful wave of action. These cases bring the climate crisis to the forefront of the legal system, challenging the longstanding impunity enjoyed by the fossil fuel industry.  By holding individuals accountable, these lawsuits aim to dismantle the corporate shields that have protected the industry from bearing the full weight of their actions and push for meaningful change in the fight against climate change. Similar to the tobacco lawsuits, which ultimately led to the Master Settlement Agreement[7], these cases have the potential to reshape the energy landscape, forcing the industry to take responsibility for its actions and accelerate the energy transition to a sustainable future. 

While the oil industry has been able to delay and deflect responsibility for decades, the legal landscape is shifting. The momentum for accountability is growing, fuelled by increased awareness of the climate crisis and its devastating impacts. Climate lawsuits could be the catalyst for a fundamental shift in the relationship between the fossil fuel industry and society. Just as the tobacco lawsuits ultimately led to a decline in smoking rates, these climate lawsuits could pave the way for a future where the oil industry is forced to prioritize sustainability over profits, ushering in a new era of clean energy and a healthier planet.

Is Blended Finance the Answer to Climate Tech’s Funding Slump in Economic Turbulence?

Mostafa Monira Firdouse, Green Finance Advisor. Friends of the Earth (HK)

Key word: Climate tech, blended finance, innovation, ESG & SDG

At the beginning of 2024, climate tech start-ups are running into a major bottleneck. Funding for companies ready to build commercial-scale facilities is declining. Investment dropped 20% in the first half of 2024 compared to the same period last year but backing for growth-stage companies fell even further. 

But it’s not all doom and gloom. While climate tech investors are keeping a tight grip on the purse strings — due both in part to the tough macroeconomic climate and uncertainty ahead of the US election — deals and even mega-deals are still getting done. Climate tech start-up kicked off 2024, raising $8.1 billion.

Reasons for downward trend of investment

  1. Solar & wind market uptake: Part of the reason for the fall is that more mature sectors like wind and solar need banks and governments – rather than early-stage investors – to fund big deployments. Solar and wind start-ups are getting a much smaller share of investment than in the past. This is because the technology and the markets for them already exist, it’s cheaper and profit driven. 
  2. Global risks focus: Globally, climate-related focus much concentrated to biodiversity loss, natural disasters and extreme weather events. Against this backdrop, in difficult geopolitical and financial times, investment needs to be channeled to where it will have the most impact.
  3. Speeding-up supply chain decarbonization: Decarbonization technologies mostly exist in the market, so, investors are focusing funding companies in technology deployment, such as, renewable generation, power grids, green energy, transportation, energy storage and so on.
  4. IPOs, SPACs, Acquisitions: Overall, IPOs, SPACs, and M&A transactions decreased by 50 percent in 2023. SPACs, in particular, saw an 89 percent downturn, signaling a potential collapse in that market for climate tech companies. Transportation and Energy saw the largest number of companies go public or get acquired, representing 64 percent of the sector’s total exits in 2023. More than 80 percent of M&A deals in the climate tech space were for undisclosed amounts.
  5. Corporates: Since 2020, corporates have emerged as the most active acquirers of companies, responsible for 41 percent of all acquisitions. Notably, BP, Shell, and Schneider Electric have been particularly significant players.
  6. Risks: Identifying potential impact driven climate tech involves HUGE RISK for investors, such as:
  • Technology Risk: Assessing technology risk, specially, for the new technology, often the single biggest issue investors face. Risk exists at each step through from concept to early and late prototypes, all the way to first-of-a-kind (FOAK) and commercial operation stages. 
  • Execution or Project Risk: With a database of over 16,000 projects globally, Bent Flyvbjerg estimates that over 90 percent of projects (construction) aren’t completed on time, overrunning by an average of 60 percent. 
  • Geographic Risk: The success of specific solutions will greatly depend on the local context. Some innovations may be more applicable or relevant in certain geographies than in others.
  • Geo-political Risk: With this rising geo-political issue, lack of law/regulation, inflation and FX volatility etc. posses additional risk for FOAK to take-off at scalable stage.

However, as discussed in my previous article (January), climate technologies need more money than venture capital firms usually provide, and they’re riskier than private equity and infrastructure funds are willing to support. To make these technologies more widely available, we need a different approach to financing. Like; 

  • Public-sector support to lower the cost of capital and attract private investment.
  • Blended finance models, which combine public and private money, are important for funding riskier projects in the early stages. 

Blended Finance Ecosystem

It is now widely accepted that the energy transition is a technological revolution which will play out over the next two decades — and potentially longer. It will harness the power of many new technologies, many of which are not the present options in their respective sectors.

So, it is imminent that we need blended finance to support projects or initiatives that aim to generate both financial returns and positive social or environmental impact. And keep continue financing innovation to create pathway to achieve environmental, social and economic impact towards sustainability & SDG.
