  • 化工是全球最大的行业之一,年收入约为4.7万亿美元。此外,它创造的产品深深嵌入了世界上最大的价值链,如制造业和建筑业。

    2021年,化学工业的全球二氧化碳排放总量约为9.25亿吨,约占总排放量的2%。与此同时,该行业正在发生根本性的变化,包括消费者对低碳产品的需求增加,消费者对回收和使用再生材料的意识增强;对资源节约型生产的需求增加;监管压力加大,要求更严格的材料要求。


    化工作为欧洲能源密集程度最高的行业之一,在能源体系重组和减少二氧化碳排放方面可以发挥特殊作用。考虑到这一点,我们研究了多个国家的化工行业的20多个脱碳项目,包括比利时、芬兰、法国、德国、意大利、荷兰、挪威、西班牙和瑞典。我们的研究结果表明,企业可以通过追求蒸汽产生、利用余热、改变电力采购和提高能源效率来减少排放。

    考虑到数据的规模和可用性,我们选择将分析和说明性示例集中在德国的化学工业上。然而,这并不否定脱碳杠杆对其他国家的普遍适用性。

    • 《清洁工业协定》强调必须摆脱对化石原料的依赖。这对化工行业构成巨大挑战——目前其价值链中超过90%的碳元素源自原始化石原料。值得注意的是,直至2050年,碳仍将是绝大多数化学品及其衍生品不可或缺的核心元素。因此,必须建立全新的碳管理机制,确保无论碳源如何,都能彻底阻止二氧化碳排入大气。欧盟需要制定一个清晰且全面的方案,以解决化学行业及其整个经济领域所使用的碳排放问题,这一点得到了多个成员国的倡导。.这一愿景应当成为即将出台的《化学工业行动计划》的一部分,并且应当:-强调强大的创新元素,解决欧洲在创新方面的不足,例如在新材料和新产品方面;-建立明确的计算方法和验证体系,以衡量回收和生物质衍生成分的含量,包括质量平衡的供应链管理和标准化的可持续性标准;-考虑新的措施,以创造更多的市场需求并支持可靠的商业案例,经过全面的影响评估后,这些措施可能包括针对产品特定法规(如PPWR、ELVR或ESPR)中涵盖的新来源循环碳的额外碳含量要求;-考虑化学产品和化学公司在欧盟碳去除战略中的作用;-最大限度地增加化学工业的生物质和回收原料的可用性,并与其他经济部门建立公平竞争的环境;-确保对投资于循环解决方案的公司的持续公共支持和资金投入。

    • Over the past few years, Europe has faced unprecedented challenges, notably with the COVID pandemic and Russia’s invasion of Ukraine. This year, 2023, directly follows this difficult period characterised by the economic downturn, high energy prices and increasing competition on the global stage. We hope that 2023 will first and foremost bring peace to Europe. At the same time, the energy crisis and supply chain issues have laid bare the need to strengthen Europe’s industrial resilience to undertake an ambitious transformation towards the 2050 EU Green Deal goals. Our European chemicals industry supports the EU Green Deal and has the ambition to go climate neutral by 2050. This means, we need to change how we produce and what we produce in less than 30 years. And we need to do this while remaining globally competitive so that we could continue supplying to important EU value chains, including clean tech. Indeed, we are facing the biggest transformation in the history of our sector, as we go climate neutral, circular, and digital at the same time as transitioning to safe and sustainable chemicals. All these actions require billions of additional investments between now and 2050. We need certainty that Europe is an attractive place for our industry to invest. This is why the implementation of  the dedicated Transition Pathway for our sector, published by the European Commission in January 2023, is vital to keep not only our industry in Europe, but also all other value chains depending on chemicals. Chemicals are everywhere, and are present in more than 90% of manufactured goods. They are indispensable for disinfectants, medical devices and smart sensors to monitor health, for example. Solutions developed by the chemical industry extend the lifespan of wind turbines, turn waste into sustainable fibre for new clothes, and make electric vehicle batteries more powerful and efficient. This is why having a strong and thriving EU chemical industry will remain key to achieving the objectives of the European Green Deal and our strategic autonomy.
