Our sustainability goals for Hertford 2030

In 2021 we conducted a baseline audit to establish our current carbon footprint. This has estimated our total emissions at 5,992t CO2e, for the reference year 2018-2019 (as the most recent full year view pre COVID). A breakdown is shown below.

The Greenhouse Gas Protocol classifies emissions into three scopes: Scope 1 (direct emissions), Scope 2 (indirect emissions – purchased energy), and Scope 3 (all other indirect emissions – not energy-related).

This is the single largest component of our scope 1 and 2 emissions, accounting for over 99% of our scope 1, and around 9% of overall core emissions. We recognise that replacement of current gas-based solutions will be challenging on a practical level, and also from a cost perspective. Up-front capital costs are likely to be significant, and alternative energy sources currently attract a higher price. Swapping over to electricity without paying attention to the broader need to reduce overall energy demands should also be avoided. Until we are able to develop a clear plan in this area, our target will necessarily remain under review, and subject to later confirmation.

We already draw the majority of our energy in this category from renewable sources – saving around 440 tCO2e of emissions – but could remove the remainder.​​​​​​​​​​​​​​

Catering accounts for 27% of our core emissions, of which meat and dairy represent 77%.

• Increasing take-up of meat alternatives by improving the range and appeal of those, and by affording them the most prominent positions on selection menus and across servery layouts (i.e. ahead of meat options).
• Where selections are required, defaulting to non-meat options as the standard – i.e switching around our current default settings.
• Reducing the amount of meat in standard portions
• Reducing food waste through improved forecasting and planning

Options involving removing meat / dairy provision (e.g. meat-free days) were considered, but not included. There were two primary reasons for this. First, our preferred approach is to encourage and support amended behaviours, and forcing these through removing choice would run counter to those aims. Secondly, approaches that make special occasions of not doing something can simply act to reinforce the notion that those things represent the norm, which is the precisely the view we should be aiming to alter.​​​​​​​

This is a challenging area for reductions, as in many cases there are few low / no emissions supply options for goods and services that are critical to our day to day operations.

• Selecting providers with strong sustainability credentials, where available
• Choosing low carbon product and service alternatives where we can (maintaining quality)
• Favouring products that can be used multiple times rather than those that have a short usable life

We hope to achieve at least a 20% reduction through the combination of such measures.

• We will adopt an economy-only approach to all travel bookings
• We will make use of virtual meetings in place of travel where possible​​​​​​​

Beyond core emissions are the downstream supply related impacts caused primarily by travel of students and conference guests to College, and in particular those travelling from overseas. These emissions are considerably larger than core, representing around 70% of our total footprint. While not currently reportable under the GHG protocol, we have determined to seek improvements here too.

Achieving reductions in this area presents challenges to our core aims and objectives, as well as a significant portion of our current income. Our approach will thus be founded upon a steady minimisation, avoiding any compromise to our academic activities, and positioning ourselves to be able to mitigate financial impacts.

• Encourage lower carbon methods of travel for our students (e.g. public transport), supporting this through practical support for storage over vacations, or finding ways to incentivise such choices.
• Seek to redesign current services to be less carbon-intensive, by adapting the length of our own college-run (i.e. conference-based) courses, to reduce turn-over travel while maintaining volumes.
• Develop alternate, lower carbon-cost, commercial revenue streams to displace carbon-heavy services over time. ​​​​​​​
