Summary of 2022
In 2019, we introduced a new approach to measuring and assessing our environmental performance, using the Sectoral Decarbonisation Approach (SDA) methodology to set ourselves a number of environmental targets, alongside more traditional environmental targets or key performance indicators (together, the KPIs). The SDA methodology is the only approach with transport sector-specific metrics, using climate science to enable organisations to set targets relevant to their industry. We set new SDA KPIs on traction energy usage, traction carbon emissions and total (Scope 1 & 2) carbon emissions, which at the time met the 2018 Intergovernmental Panel on Climate Change (IPCC) goal of controlling the increase in global warming to below 2°C. The SDA KPIs were set over an initial seven-year performance period – 2019 to 2025 – from a 2018 baseline. We supplemented these SDA targets with KPIs on site emissions, waste to landfill and water usage, which we also aim to achieve over the same seven-year performance period against a 2018 baseline.
Our intention is to review the SDA KPIs on a regular basis as climate science, technology and forecasting methods improve, and we intend to refresh our KPIs in 2023, using 2022 as the baseline year and aligned to the ambition of the Paris agreement to control the increase in global warming to below 1.5°C. These targets have a purpose to aid our commitment to an overarching goal of achieving net zero (Scope 1 & 2 emissions) across the Group by 2040.

This had the effect of reducing the environmental efficiency relative to normalised operation. The year began, therefore, with Covid-19 continuing to have a significant impact on our intensity metrics.
Over the full year, the 2022 traction metrics have all improved on the 2021 result as patronage improved over the year. Whilst we remain behind our 2025 targets on all three traction metrics, we are seeing the start of a positive impact of ZEV transition, mostly in the UK, and expect this to continue as we roll out the ZEV transition in future years and therefore there remains potential for material improvement in intensity metrics as this progresses.
There was a good performance on absolute site emissions and landfill waste disposal in the year, with a 5.8% and 6.1% respective reduction year on year. Whilst water consumption slightly increased on 2021 levels, this was a good result given both the service curtailments and low office occupancy levels in 2021 reduced water usage significantly, e.g. from vehicle cleaning.

The fact that, measured in MWh, emissions are up 29% year-on-year whereas measured in tCO2 they are up 25% is driven by a combination of definitions, measurement standards and changes in energy ‘mix’.

Health and Safety
Safety is embedded in our culture and at every level of the business. Our safety performance in 2022 is our best ever result. In the UK we were recognised with the award of the sixth Sword of Honour by the British Safety Council. In North America School Bus, all of our operating authorities received the highest safety rating from the US Department of Transportation (DOT) and Canadian Provincial Governing Agencies and in ALSA we also achieved external recognition for our safety achievements and AENOR certification for road safety.
