OFI SF7 New Integrated Design Approach for Wharves in Nova Scotia to Meet 2050 Target GHG Emissions Set by the Environmental Goals and Climate Change Reduction Act

新斯科舍省的《环境目标和减少气候变化法案》（Environmental Goals and Climate Change Reduction Act）设定了加拿大最雄心勃勃的气候变化目标，其中规定到2030年将温室气体（GHG）排放量在2005年的基础上减少53%，到2050年实现新斯科舍省的净零排放。挪威的海洋建筑行业是一个重要的温室气体排放源。温室气体的排放量目前没有考虑到海洋结构的设计、建造和维护。为了达到省级排放目标，需要考虑气候变化对码头恶化加剧（海平面上升和海水盐度升高）的影响，将温室气体排放的影响纳入NS海洋结构的结构设计和生命周期评估。文献调查表明，在评估海洋结构的设计方案及其对气候变化的影响时，缺乏定量方法，可供有管辖权的当局、设计工程师或承包商用于量化概念和详细设计阶段的温室气体排放[2,3,4]。

The Environmental Goals and Climate Change Reduction Act of Nova Scotia (NS) sets the mostambitious climate change goals in Canada whereby it specifies reducing greenhouse gas (GHG) emissions by 53% below 2005 levels by 2030 and to achieve a net-zero emissions in NS by 2050 [1]. The marine construction industry in NS is a significant GHG emitter. The magnitudes of GHG emissions are currently not factored in the design, construction, and maintenance of marine structures. To meet the provincial emission targets, work is required to incorporate the impact of GHG emissions in the structural design and life-cycle assessment of marine structures in NS by considering the impact of climate change on the increased deterioration of wharves (increased sea level and water salinity). Survey of literature indicates the lack of quantitative methods that can be utilized by the authorities having jurisdiction, design engineers, or contractors to quantify the GHG emissions at the conceptual and detailed design stages when evaluating design options for marine structures and their impact on climate change [2,3,4].
