Climate Change Reducing our GHG emissions at our operations is a key component of our climate change strategy. Our current long-term target is to achieve carbon neutrality by 2035. However, we recognise we have the ability and mechanisms to accelerate this target, particularly for our Nova Operation. We have already seen a 14% reduction in our emissions since FY19. Emissions intensity at the Nova Operation has, on average, decreased since the solar farm was commissioned. However, we recognise that solar optimisation is a key improvement opportunity from the graph below. This will be a focus area for FY22 as part of our emissions reduction projects described on page 61. We have set a short-term target to reduce operational GHG emissions (Scope 1 and 2) by a further 10% on our FY20 baseline during FY22. This will be achieved through the execution of our emissions reduction roadmap, which has been outlined throughout this section. The key components of this roadmap include: • ventilation on demand • solar optimisation • hybrid generators; and • culture and behaviour changes. During FY22 we have committed to improving our understanding of our total carbon footprint emissions, engage and influence our suppliers and customers, and make clear choices on how we do business with consideration of climate change. We will: • comprehensively understand and report on our total carbon footprint which includes Scope 3 emissions on which we have an influence (and/ or financial input). This will include emissions from our joint venture partners • complete baseline research on our Scope 3 and value chain emissions • complete a risk assessment and gap analysis of our current contractors and suppliers climate change policies, reporting, TCFD alignment, and climate change targets and initiatives, to understand alignment with our own policy and strategy; and • refine our procurement and contracting framework to ensure climate change is part of our contract evaluation model and assessment matrix for award of contracts or supply agreements.
