was to analyse the GHG baseline for a major coastal infrastructure that will attract regional investment for several industrial process facilities. The purpose of the study was to develop a baseline estimate of the GHG emissions for the construction and 50-year operational life of the infrastructure. The outcome was that the baseline estimate supported the roadmap required for reducing GHG emissions during both the construction and operational phases in the development of

the infrastructure. Carbon Column (see Figure 3 ) provides a focussed approach that offers technical insights and solutions recognising the Taskforce for Climate-related Financial Disclosures (TCFD), GHG Protocol, and ISO standards. The delivery is through a Tiered Reporting Process with four internationally recognised Tiers: Tier 1 – Default factors based upon knowledge of project parameters, such as fuels, materials, services, and product types. Tier 2 – Application of benchmark factors for equipment type, characterisation of fuels, and estimate of consumption. Materials, services, and product types and estimates of quantities and transport type and distances. Tier 3 – Application of defined factors for specific equipment and details of final fuel types and rates of consumption. Specific material quantities and regional or source factors and transport type and distances. Feedstocks and product quantities, mode of transport, and distance to markets. Tier 4 – Measurement – Fuel quality and quantity, power consumption, and leak detection. The application of Wood’s ENVision

Our team effectively deployed ENVision across a chemical complex that included 26 large chemical units in Saudi Arabia, with real- time emissions data collation, verification, and reporting. Utilising the ENVision tool, over 1.3 million individual data points are updated every 30 seconds to operators to provide the necessary information to help drive efficiency and reduce emissions. The client indicated an improvement of 10 times faster reporting methods and a better vision of plant operations, which resulted in a reduction in effort associated with emissions reporting by around 80% and a reduction in excess emission time by 40% through early identification. It is also becoming more critical to understand not just the carbon footprint of our assets, but also the carbon footprint of the activities associated with building, maintaining, and modifying them. To that end, Wood, and its project services subsidiary company rhi, developed the Carbon Column toolkit to allow us to assess the carbon emissions associated from material sourcing, transportation, and construction activities (among other scope 3 emissions). This enables ourselves and our clients to make informed decisions and minimise the carbon footprint of project delivery. One example of this tool being implemented
