We Strive to be a Good Neighbour We aim to mitigate the noise generated by certain segments of our operations. Our measures include: • Keeping all noise within legal limits and within permitted hours • Replacing noisy equipment with quieter models and providing sound insulation where applicable • Monitoring and reviewing noise emission levels from our operations • Conducting boundary noise checks in accordance with regulatory guidelines To keep the contamination of surrounding air to a minimum, we use air pollution control equipment such as scrubbers. We will continue to monitor and minimise stack emissions and the level of air pollutants. OUR APPROACH TO CLIMATE CHANGE We Recognise the Impact of Climate Change and the Importance of Addressing It We support initiatives to address climate change within our operations globally. We adopt a two-pronged approach of doing our part and enabling our customers. We do our part to reduce GHG emissions and adopt environmentallyfriendly practices in our business, as well as encourage our employees to inculcate similar habits in their daily lives. We develop products and solutions that will help our customers reduce their carbon footprint in their journey towards net zero. We track our absolute GHG emissions and emission intensity. We include the following gases for conversion to CO2 equivalent emissions in our GHG inventory – CO2, CH4, N2O, PFC5, HFC5, SF6 and NF3. Additionally, we take guidance from accredited sources for computation methodologies, conversion factors and calculation tools. The Group established our initial GHG inventory processes in 2009. Our Singapore operations achieved our first externally validated assurance statement in 2012 for a 2011 GHG inventory. Over time, we have expanded our data collection to material business units globally. In 2024, we revised our base year from 2010 to 2015 in line with best practices to use a more recent base year for emission targets. As our emissions have significantly reduced between 2010 and 2015, this change in base year means that our target of achieving a 50% reduction of our Scope 1 and 2 emissions by 2030 will become more challenging. This change further demonstrates our commitment towards a pathway to net zero. Core to our corporate purpose, ST Engineering believes in the potential of technology and innovation to reduce our operational emissions and enhance overall efficiency. To reduce Scope 1 emissions, we conduct energy audits and replace equipment and fixtures with energy efficient models when they are due for replacement to optimise energy efficiency. Additionally, we optimise energy utilisation in our operational activities such as delivery runs and engine test cell usage, and continue to electrify our vehicle fleet. To reduce Scope 2 emissions, we install solar PV systems across our global sites where practically feasible. For power transmission, we have switched to more energy efficient static converters, which replace conventional mechanically driven models. Our businesses continually streamline and reengineer production and operational processes and facilities through the use of smart systems and other technologies. We are progressively expanding the tracking, disclosure and reduction of our Scope 3 GHG emissions, building upon efforts in 2023 to establish our Scope 3 data collection and disclosure roadmap. We prioritise using carbon reduction to reduce our emissions before considering the adoption of neutralisation methods such as offsets and investments in nature-based solutions.
