France has constrained the Aquitaine region to set up a climate plan to avoid an emission of 2883 ktCO(2)eq for the period 2007-2013. In parallel, the region has decided to carry out the construction of road infrastructures in order to avoid very high congestion costs. Those road projects will involve an increase in greenhouse gas (GHG) emissions during that period. In the present context of strong sustainability, all emissions (direct and indirect) generated by those projects should be offset. At the regional level, the offsetting of GHG emissions is usually carried out by implementing carbon sequestration projects or projects that reduce energy demand. This paper aims at determining the maximum budget for financing GHG emissions offsetting projects, with computation being based on the opportunity costs of projects, the minimum cost of economic activity reduction required to offset emissions from those projects. The maximum budget devoted to GHG emissions offsetting projects should not exceed €(2001) 1920 M to €(2001) 3592 M, according to low/high traffic growth assumptions.
法国已强制要求阿基坦地区制定一项气候计划，以避免在 2007-2013 年期间排放 2883 千吨二氧化碳当量。与此同时，该地区已决定建设道路基础设施，以避免高额拥堵成本。这些道路项目将在该期间增加温室气体（GHG）排放。在当前强烈的可持续性背景下，这些项目产生的所有排放（直接和间接）都应得到抵消。在区域层面，温室气体排放的抵消通常通过实施碳封存项目或减少能源需求的项目来实现。本文旨在确定为资助温室气体排放抵消项目提供资金的最大预算，计算依据是项目的机会成本，即抵消这些项目排放所需的经济活动减少的最低成本。根据交通增长的低/高假设，用于温室气体排放抵消项目的最大预算不应超过 19.20 亿欧元至 35.92 亿欧元。
