Topic Introduction
Carbon neutrality, as a state of net-zero CO2 emissions, which can be achieved by counterbalanced all worldwide greenhouse gas emissions by carbon sequestration. Another way to reduce emissions and to pursue carbon neutrality is to offset emissions made in transportation, energy production, agriculture, and industry by reducing them through science-based measures such afforestation and energy saving and reduction emission. This can be done through development of renewable energy, energy efficiency or other clean, low-carbon technologies (https://www.europarl.europa.eu/news/en/headlines/society/20190926STO62270/what-is-carbon-neutrality-and-how-can-it-be-achieved-by-2050). In the 75th session of the UN General Assembly President Xi Jinping proposed that China will increase its National Determined Contribution and adopt more powerful policies and measures. We strive to peak CO2 emissions before 2030 and achieve carbon neutrality before 2060 (http://www.igdp.cn/wp-content/uploads/2021/08/2021-7-21-IGDP-Report-EN-What-to-Expect-in-Chinas-Second-NDC.pdf) (https://news.bloomberglaw.com/environment-and-energy/china-pledges-carbon-neutrality-by-2060-and-tighter-climate-goal). Till the end of December 2021, net zero targets has been set by 136 countries, 115 regions, 235 cities, and 682 companies, which have covered 88% of global greenhouse get emissions, 90% of global GDP and 85% of the world's population (https://news.climate.columbia.edu/2021/12/16/net-zero-pledges-can-they-get-us-where-we-need-to-go/).

Carbon Neutrality and Life Cycle Thinking
Abstract: Climate change is one of the most critical sustainability challenges facing the humanity. International communities have joined forces to mitigate climate change impact and aim to achieve carbon neutrality in the coming decades. To achieve this ambitious goal, life cycle thinking can play critical roles. Specifically, life cycle thinking helps evaluate the true climate impacts to avoid shifting emissions across processes in a product life cycle. It can also help inform consumers with carbon footprint information to make climate-conscious choices. Finally, it can help identify key processes dominating the carbon footprint of a product so that future improvement can set priorities. High quality data is required for accurate and timely carbon footprint accounting and critical challenges exist to obtain and share such data.
