This work presents an Integrated Assessment Model (IAM) developed for Ecuador, the so-called Ecuador Land Use and Energy Network Analysis model (ELENA). This model includes six distinctive sectors of the economy and displays the four geographic regions composing the country. The model enables to capture sectorial interactions, under a set of scenarios designed to evaluate the energy and land perspectives until 2050. The model is a crucial planning instrument to evaluate public policies, such as National Determined Contributions (NDC) and even more ambitious decarbonisation scenarios. Findings show that Ecuador's NDC are not aligned with the “well below” 2 °C target, committed in the Paris Agreement. Moreover, to achieve deep decarbonisation it is necessary to endorse disruptive strategies in which bioenergy and reforestation play a main role. To keep under the 1.5 °C temperature threshold above pre-industrial levels, Ecuador's energy matrix must be diversified with higher shares of low carbon technologies and electrification of energy end use in the transport, buildings and industry sectors. Biomass with carbon capture and storage (BECCS) and biofuels could transform the energy sector in a CO₂ sink.

这项工作介绍了为厄瓜多尔开发的综合评估模型（IAM），即所谓的厄瓜多尔土地利用和能源网络分析模型（ELENA）。该模型包括六个独特的经济部门，并显示组成该国的四个地理区域。该模型能够在一系列情景下捕获部门间的相互作用，这些情景旨在评估直至2050年的能源和土地前景。该模型是评估公共政策的重要计划工具，例如国家确定贡献（NDC）以及更具雄心的脱碳情景。 。调查结果表明，厄瓜多尔的国家数据中心与《巴黎协定》中设定的“远低于” 2°C目标不符。此外，为实现深度脱碳，有必要批准破坏性战略，在这种战略中，生物能源和植树造林将发挥主要作用。为了将温度限制在高于工业化前水平的1.5°C以下，厄瓜多尔的能源矩阵必须多样化，其中低碳技术的比例更高，并且交通运输，建筑和工业部门的能源最终用途应实现电气化。带有碳捕集与封存（BECCS）的生物质和生物燃料可以改变一氧化碳中的能源部门_2个水槽。
