Discover the roadmap to achieving net zero carbon built environments in Australia. The research paper lays the critical principles, targets, and pathways needed for a sustainable future. Balancing operational and embodied carbon considerations, the proposed approach aims for all new buildings and major renovations to achieve net zero operational carbon by 2030, with a phased reduction in embodied carbon quotas leading to net zero by 2040. The comprehensive strategy includes comparing and combining operational and embodied data, ensuring a holistic understanding of carbon emissions.

midst a disparity between academic theory and practical implementation, benchmarking for embodied CO2e in buildings remains a challenge. Despite lacking formal policies, industry leaders are proactively embracing CO2e assessment, driven by upcoming regulations and potential rating benefits. The study highlights persistent uncertainties, including institutional, economic, technical, and knowledge-related barriers. Precise scenario predictions, comprehensive life cycle stage consideration, and grid decarbonization are underscored as pivotal factors.

Recent research analyzed the emissions intensity of the Australian National Electricity Market (NEM) to understand how energy storage can accelerate decarbonisation. The study calculated the Marginal Emissions Factor (MEF) for each time period, representing the emissions intensity of the highest bid price generator.

The average MEF for different NEM regions was found to vary, with some intervals having zero MEF. Intra-day variability showed higher MEF values overnight and during low demand, while low MEF values occurred during peak demand. Interestingly, a strong anti-correlation was observed between MEF and spot price, indicating the need for energy storage optimization to balance costs and emissions.

Electric Vehicle (EV) charging infrastructure is essential for EV adoption. The review highlights the need for transparent pricing, continued public support, and improved data accessibility. Standardised labelling and consumer protection can enhance customer experience, while subsidies and partnerships are crucial for infrastructure development. Gathering more data and understanding driver preferences will aid in future planning efforts.

The challenges facing the Australian electricity and gas markets, include the need to transition to lower emissions generation while ensuring reliability and affordability; the impact of higher gas prices on manufacturing businesses and residential consumers, as well as the potential for supply gaps in southern states from 2024. There’s a need for continued investment in new infrastructure and technologies to address these challenges and secure Australia’s energy future.
