The reduction of anthropogenic greenhouse gas emission rates alone appears insufficient to limit the rise in global temperatures. Negative Emission Technologies (NETs) can be helpful in this critical goal by actively removing CO₂ from the atmosphere. Industrialised countries like Scotland will require NETs to address their climate targets and reach net-zero carbon emissions in a timely manner. However, the implementation of NETs has varied energy, economic and environmental implications that need to be analysed in detail. In this paper, we explore the potential energy and economic costs for implementation of land-based NETs in Scotland. This analysis is based on the calculated averaged costs of the different technologies and the availability of resources for its implementation in Scotland. We found that the country has a maximum technical potential to abate 90–100% of its annual CO₂ emissions by means of land-based NETs, thanks to its low annual emissions and large land area for implementation of NETs. Even in less optimistic scenarios, Scotland is exceptionally well suited for land NETs, which can complement and enhance the potential of more conventional technologies, like renewable energy resources. Our results show that Scotland could lead the transformation towards a carbon-neutral society.

仅人为温室气体排放量的减少似乎不足以限制全球温度的上升。负排放技术（NETs）通过积极去除CO ₂有助于实现这一关键目标从大气中。像苏格兰这样的工业化国家将需要NET来解决其气候目标，并及时达到零碳净排放。但是，NETs的实施具有多种能源，经济和环境影响，需要详细分析。在本文中，我们探讨了在苏格兰实施陆基NET的潜在能源和经济成本。该分析是基于计算得出的不同技术的平均成本以及在苏格兰实施该技术所需的资源。我们发现该国拥有最大的技术潜力，可以减少其年度CO _2的90–100％由于陆基网的年排放量低且实施网的土地面积大，因此通过陆基网产生的二氧化碳排放量大。即使在不太乐观的情况下，苏格兰也非常适合土地网，它可以补充和增强可再生能源等传统技术的潜力。我们的结果表明，苏格兰可以引领向碳中和社会的转变。
