循環經濟如何因應生物多樣性喪失

We have already seen some decent ambition around nature at the start of COP when countries have committed to halt deforestation by 2030. Although not binding, a step in the right direction. Today’s nature day is too proving promising, with 45 個國家承諾改變其農業和糧食系統 through policy and innovation to protect and preserve nature. Again, this is a step in the right direction but these pledges still aren’t going far enough. 

如果不解決氣候危機，我們就無法解決 生物多樣性 loss and land degradation. Our biodiversity and natural assets work as carbon sinks on a large scale and are the most effective way of capturing and storing carbon we have. But not only is our biodiversity a crucial element in our fight against climate change – it is also under massive threat. Biodiversity is declining rapidly, and the latest figures from the UK suggest 47% our biodiversity has been lost in the last 50 years. Some already speak of a sixth mass extinction.  

But what threatens our forests and ecosystems? According to UNEP, 90% of it comes down to the extraction and processing of 自然資源 – 與施工 發揮著重要作用。 為了成為解決方案的一部分，我們有一個工具來解決這個問題。 

當談到氣候變遷時，路徑是明確的——我們需要使我們的經濟脫碳，而諸如此類的框架 淨零 help us understand the issue. But that alone won’t solve the destruction of our natural world. Greenhouse gas emissions are just one issue we are facing and if we cut our emissions to zero there are many more crises to come: deforestation and biodiversity loss are among the most pressing ones.  

Moving to a Circular Economy can be an answer to these issues. While Circular Economy is able to effectively 減少碳排放，它能夠做更多的事情——讓我們擺脫當前線性經濟的破壞性開採行為，轉向一種再生模式，讓所有材料保持循環，並減輕對自然系統的壓力。  

那麼需要發生什麼？與我們在全生命週期碳方面的發展類似，我們需要研究產品、製程和材料的整個生命週期對生物多樣性和自然的影響。為了做到這一點，我們需要整個供應鏈的清晰度和透明度，這將使我們能夠引導我們的經濟度過向完全循環的過渡階段，從而避免使用最有害的材料和工藝。  

Secondly, we need to keep materials in loop for as long as possible to avoid the need for virgin materials. That means prioritising refurbishment over new built, trying to procure reused materials where possible and designing for deconstructability to allow for the future use of the building’s components. Putting the necessary infrastructure in place to enable that will be a crucial task for the industry.   

最後，重生。一旦我們減輕了自然世界的壓力，那些因我們的經濟活動而退化的地區就可以再次充滿生機。  這包括透過基於自然的解決方案曾經存在於我們城市中的自然和生物多樣性。
