净零碳排放的概念来自物理气候科学。然而，它是通过社会、政治和经济制度运作的。我们确定了净零的七个属性，这些属性对于使其成为成功的气候行动框架至关重要。这七个属性突出了减排的紧迫性，减排必须是前期工作，以及覆盖所有排放源，包括目前困难的排放源。这些属性强调了社会和环境完整性的必要性。这意味着二氧化碳清除应谨慎使用，碳抵消的使用应有效监管。净零排放必须与更广泛的可持续发展目标保持一致，这意味着公平的净零过渡、社会生态可持续性和追求广泛的经济机会。它是在社会、政治和经济背景下实施的。该观点提出了七个属性，这些属性对于实际有效地实施净零至关重要。
The concept of net-zero carbon emissions has emerged from physical climate science. However, it is operationalized through social, political and economic systems. We identify seven attributes of net zero, which are important to make it a successful framework for climate action. The seven attributes highlight the urgency of emission reductions, which need to be front-loaded, and of coverage of all emission sources, including currently difficult ones. The attributes emphasize the need for social and environmental integrity. This means carbon dioxide removals should be used cautiously and the use of carbon offsets should be regulated effectively. Net zero must be aligned with broader sustainable development objectives, which implies an equitable net-zero transition, socio-ecological sustainability and the pursuit of broad economic opportunities.Net-zero emissions is more than a concept of physical climate science. It is implemented in social, political and economic contexts. This Perspective proposes seven attributes that are critical for the practical and effective implementation of net zero.
