GHG EMISSIONS, RENEWABLES AND ENERGY EFFICIENCY In 2021, the Group achieved a 30% absolute reduction of GHG emissions with 2010 as the base year. This translated to a 46% reduction in intensity. While there was a slight increase in emissions as operations recovered from 2020 the Group is still on track to achieve the target of a 50% absolute reduction by 2030. Our Singapore operations consolidated their efforts into a single GHG emissions assurance statement. Our GHG emissions were verified in accordance with ISO 14064-1:2006 Greenhouse Gases. In 2022, we plan for the external assurance process to be aligned with ISO 14064-1:2018. We continued our roll out of solar photovoltaic (PV) systems across our global operations to increase the proportion of renewables in our energy mix. We added about 44,000m2 of solar panels in Singapore, bringing the total to 110,000m2. This increased the number of buildings with solar panels deployed to 39, compared with 24 in 2020. In our Singapore operations, the solar PV systems generated 8% of the total electricity used. This was the same proportion as in 2020, as our businesses ramped up from a lower production rate. Our business units in Singapore initiated the use of electric vehicles with a pilot of eight vehicles and two charging stations. We intend to replace the current fleet of internal combustion engine vehicles in phases over the next few years. Our businesses continue to replace production equipment and cooling systems to reduce GHG emissions.
