The first two case studies in what we hope will be a growing library.

Case Study 1: Hampshire Cultural Trust and Greenly #

Josephine Lethbridge and Jo Lindsay Walton, November 2023

Highlights -#

  • GLAM sector organisations face many challenges in decarbonisation, including need for financial support to decarbonise, and expertise in carbon accounting and management planning.
  • Carbon accounting and management support needs to be offered accessibly and at scale, and there is a role for automated approaches to help this happen.
  • Interdisciplinary academic expertise, including fields like the digital humanities, AI ethics, critical data studies, and political ecology, can usefully inform the further development of carbon accounting platforms and tools.

Hampshire Cultural Trust (HCT) is an independent charity that manages and supports visitor attractions, museums, art galleries and arts centres across the UK county of Hampshire. The trust runs a wide variety of workshops, classes, events and exhibitions, welcomes over 15,000 children every year to its immersive education programme, and runs projects with individuals, groups and communities that would otherwise not have access to culture. In addition, the trust cares for 2.5 million objects relating to Hampshire’s rich history. It employs around 140 staff and has over 400 volunteers. +#

In addition, the trust cares for 2.5 million objects relating to Hampshire’s rich history. It employs around 140 staff and has over 400 volunteers. HCT has made a concerted effort to better understand and improve its environmental impact since 2019. Rolling, detailed action plans for the next 12 months have been developed, and a dedicated project team has been set up – 12-14 people from across the organisation, all of whom dedicate half a day per week to HCT’s environmental action. -With the support of a small HEIF grant via the University of Sussex, we — Josephine Lethbridge and Jo Lindsay Walton, with support from other DHCC members — were able to engage with HCT in 2023 to find out about their approach to decarbonisation and to offer support. This support included bringing in the carbon accounting platform Greenly (see below) as a project partner.

Prior to this project, HCT had carried out a biodiversity opportunity review and buildings-level analysis for scope 1 and 2 emissions. (Scope 1 refers to direct emissions, e.g. vehicles, burning fuel on site, and scope 2 refers mostly to indirect emissions from buying electricity and heating/cooling). Based on this analysis and in partnership with the local council, HCT had also installed a total of 654 photovoltaic solar panels across four of its sites. In June 2022, HCT was given bronze accreditation from the Carbon Literacy Project and became the first museum organisation in the UK’s south to achieve Carbon Literate Organisation status.

When our project began, the trust’s main ambitions were to:

  • Further develop action plans so as to achieve its commitment to reach net zero by 2030 (scopes 1 & 2) as well as reducing scope 3;
  • Engage internal and external stakeholders around the severity of the climate crisis and the need for action.

HCT’s immediate ambitions, and reasons for getting involved in this project, were to carry out deeper analysis of its carbon impact, and include those learnings in the next version of its environmental action plan. As a charity, HCT does not have funds readily available to enact the costlier elements of this plan. Over the next year, the organisation has ambitions to raise £100,000 in funding to dedicate to its sustainability trajectory.

HCT’s key challenges, we heard at the outset of the process, included:

1. Accessing expertise

  • Comprehensively calculating carbon emissions, and devising a plan for reducing them, are complex tasks requiring specialist skills and knowledge.

2. Prioritising and coordinating action -Of course, many decarbonisation actions can be taken even without comprehensive emissions data. However, without such data it is difficult to:

  • know what to prioritise,
  • ensure that teams across the organisation understand and feel invested in sustainability,
  • persuade senior management to commit finance and other resources, and
  • ensure a coordinated, evidence-based approach to new sustainability initiatives or projects.

3. Mobilising staff time and other resources to deliver -With staff often juggling many duties, it has sometimes been hard to get buy-in on sustainability initiatives. Staff may feel that sustainability is not really part of their job description. In the case of the HCT-Greenly engagement, however, there was dedicated staff time to compile and prepare the data for Greenly’s analysis.

Greenly #

To make timely progress toward net zero, all sectors need to decarbonise. But organisations come in many sizes and shapes. Some may have in-house expertise to do their own carbon accounting, or have resources to invest in climate consultants — but a great many don’t. Greenly is one of many fast-growing tech companies that position themselves as a tech solution to the time-consuming and complex tasks of carbon accounting and the creation of carbon management plans. There is some overlap between what Greenly does and climate consulting, except that ‘climate consulting’ tends to refer to more expensive, bespoke engagements, whereas Greenly wants to offer a relatively more accessible package. Companies operating in a similar space might include Watershed, Sweep, Plan A, Persefoni and Normative.

Founded in France in 2019, Greenly has more recently expanded into the US and UK. At the time of writing, Greenly has c. 170 staff and over 1500 clients. The bulk are small and medium-sized enterprises (SMEs), though they are increasingly working with bigger clients. Greenly offers its clients annual greenhouse gas (GHG) reports, support from its climate experts (i.e. carbon accounting and management experts), and automated carbon reduction suggestions through its platform.

Greenly calculate carbon footprints using a hybrid approach of spend-based and activity-based assessment. Spend-based assessment is relatively quick and easy to do. The amount a company spends across various categories is multiplied by numbers (Emissions Factors) representing typical GHG emissions associated with that type of spend, to get a rough idea of emissions. Activity-based assessment is much more detailed, and can require very complex data collection and analysis, but can be much more accurate. Greenly emphasise that carbon accounting should support actions to decarbonise, not become an end in itself. The flexible mix of spend- and activity-based assessment is a way of doing this while also keeping costs down.

Fig. 1. Screenshot from Greenly’s website

As well as the core carbon accounting offering, clients can also use the Greenly platform to engage employees and suppliers in the company’s climate journey, purchase carbon offsets, and/or work towards receiving the Greenly Net Zero Contributor certification (achieving this is reliant on paying Greenly to co-develop or audit these plans). They can also access some resources, such as slide decks, to help with communicating around decarbonisation and net zero.

Additional support from Greenly’s climate experts, for example providing deep-dive analysis into a particular portion of an organisation’s emissions, or in putting together a decarbonisation strategy, is also available for purchase. Further services are available through the Climate App Store section of the Greenly platform. This offers a wide range of tailored carbon calculators, from basic calculators which are free to use, to sector-specific paid-for ‘premium’ apps such as the cloud app, which integrates with cloud service provider APIs to measure carbon emissions based on hourly electricity map data. Similar premium apps are also available for websites, events, freight, menus and construction site carbon calculators, amongst others.

HCT was a slightly atypical client for Greenly, and part of the appeal of the project for Greenly was the chance to try out its tools and expertise in a new context. At the same time, expanding to serve new types of clients is very much part of Greenly’s model. Greenly aims to eventually create a platform that is near 100% automated, by learning from each client and building those learnings into the platform, so that next time a similar client comes along, they don’t need nearly as much face-to-face help.

Outcomes #

The HCT team was thrilled at the level of granularity available in the emissions data, and the variety of charts and views available. One team member told us: “We’re all a bit rabbit in the headlights at how brilliant it all is … It probably would have taken us a few years to get to this place.”

Overall, the spread of emissions over different aspects of HCT’s operations, and what this implied about main areas to focus on, tallied with HCT’s expectations, apart from some surprise at the scale of emissions deriving from service and product purchase.

The main benefit of the analysis was seen to be its potential in lending clarity and gravitas to the team’s existing plans. One told us: “We were really stuck. Some people want to see data and figures and proof backing up suggested approaches and action plans. So Greenly has really helped with that.” Another said: “Just having the data is fantastic. There’s going to be so many ways we can use it – in funding applications, fighting our case and trying to push things through with the council, and internally as well, being able to get people on board”.

We asked how the engagement could be further improved. HCT suggested they would be keen on more advice and support on using the data internally. This might also have included more active encouragement from the Greenly side for senior staff to engage, particularly for the final presentation, and to involve more staff from across the organisation in data collection.

Greenly were transparent about various assumptions, estimates and compromises which needed to be made along the way. “We were able to observe how such decisions, while made for good pragmatic reasons, tended to grow less visible over time. While this didn’t especially worry the HCT team, we wonder whether just a hint more acknowledgement of the estimated nature of the assessment could go a long way in terms of developing clients’ understanding of the nature of their emissions, and inform more robust measurement and action in the future.” For more on the relationship of uncertainty data and climate decision-making, see Communicating Climate Risk: A Toolkit.

As HCT mentioned internal comms as a topic of special interest, we also invited Climate Action Unit (CAU) to share their perspectives. We were joined by Freya Roberts for a wide-ranging discussion. One key principle which emerged was the importance of two-way dialogue: that individuals should get the space and support to express whatever challenges they face in taking action.

Future directions #

At time of writing, we are working on refining our recommendations for project partners. We hope to continue to work with both HCT and Greenly, and have recently sought follow-on funding (AHRC IAA and AHRC Net Zero Design Accelerator) to support this work. On the Greenly side, we see potential for expanding resources to support clients in using data internally and externally, opportunities around quantifying and visualising uncertainty, as well as localising decarbonisation recommendation resources, and transforming approaches to carbon offsetting. On the HCT side, we are exploring the possibility of delivering workshops for internal and/or external audiences to expand the opportunities for dialogue on decarbonisation.

If the ambition to automate carbon accounting is realistic – if Greenly are going to be able to make the process seamless and intelligible for their clients, and create GHG assessments that are accurate enough for those clients to develop comprehensive, tailored action plans – then the potential benefits could indeed be enormous. One presumes that costs might be so reduced that the carbon accounting platform would become accessible to organisations in the cultural sector that have traditionally struggled to raise any funds for this kind of work.

There are also potential policy implications. One expert we interviewed as part of our background research, who is a Managing Director of a Sustainability Consultancy in Southeast Asia, commented, “If platform services reduce the cost of decarbonisation for SMEs, then I can see that being a huge piece of the puzzle that’s missing. It would actually help the regulators roll out wider requirements on disclosure and perhaps even reduction. They’re very reluctant to do that right now due to high costs and perceived difficulty”.

The tech platform approach to carbon management is relatively new, and approaches are evolving rapidly. It is crucial that its evolution is shaped by all stakeholders, including interdisciplinary academic expertise. The use of automation indicates a clear role for disciplines and fields such as the digital humanities, critical data studies, AI ethics, and political ecology, as well as many different climate-related fields within the social and physical sciences.

Given that the main beneficiaries of the platform-based approach to carbon management include SMEs, NGOs or cultural organisations that those that don’t have the finances available for more expensive, sector-specific consultants, it’s crucial to consider how such platforms can better serve the specific needs of those organisations in the context of the overall aim of a just transition. The design of automated systems is seldom value-neutral, and we see collaborative, interdisciplinary approaches as the best way to ensure reflection and conversation around these issues.

It is also key to keep an open mind about the future. From what we have observed here, it is still difficult to say exactly how existing carbon accounting approaches would fit into the bigger social and economic shifts implied by most moderately positive vision of the future. Bold policy changes, and/or social, cultural and economic shifts, may transform the assumptions on which such engagements have operated to date.

James Baker, Lisa Otty, Christopher Ohge et al. 2022

This was a workshop run in 2022 with DH researchers as the primary audience. We underscored how as arts and humanities researchers it is our role to probe the values, the power structures, and the future imaginaries that underpin sustainable digital solutions. Moreover, given the immense and monopolistic power wielded by the global tech sector, and the critiques of this power that are part of the Digital Humanities, this community is well positioned to create change and demonstrate to our colleagues and collaborators how change can happen. Our use of technology and infrastructure should be informed by the ways corporate economic, cultural, and scientific power perpetuates and exacerbates the crisis. Choosing a hardware or hosting provider, for example, should mean considering direct environmental impacts, broader environmental policies and record of the provider, and more broadly still, the kinds of collective future that such a collaborative encounter presupposes. We should be able to candidly explore the complex and sometimes contradictory nature of our ecological impact: we should be able to measure and model where possible, while also creating context around our measurements, flagging uncertainties, and advocating for transforming wider conditions.

Themes #

  1. decarbonising our research and teaching,
  2. working at the intersection of humanities and digital technology to understand the role of data science in climate transition and climate justice,
  3. transforming DH (and knowledge institutions) within broader transformations of society.

Structure -#

Introductions. Refining questions, challenges, opportunities (40 mins)

First, facilitated brainstorming and rapid co-production will refine questions, challenges, and opportunities around climate change and the digital humanities that are relevant in your local contexts. This part of the workshop will draw on the workshop model developed for the November 2021 “Greening DH summit”. This model balances the knowledge that time is fleeting and there is an impetus to act, with an awareness that participants will have variable expertise regarding the climate crisis, the energy/resource costs of digital technologies, and ‘green computing’ practices.

Access the slides.

10 minute break

Greening DH Toolkit (50 minutes)

Second, participants will be asked to respond to sections of the DHCC’s work-in-progress Greening DH Toolkit. Specifically, participants will work in small groups to evaluate prototype sections of the toolkit, and to design their own implementation strategies for these sections. In keeping with the “RE-MIX” theme of the conference, we will discuss how agencies, funding bodies, and institutions in the Benelux region can be leveraged to enable implementation, as well as the barriers they might create.

  • Introduction to the Tool-kit and how it is structured [5–10 min]
  • Engaging with the tool-kit
    • Participants to examine a section of the tool-kit that speaks to their needs and interests [20 min]
    • Formulate responses–questions or provocations or suggest edits–and discuss as a group [25 min]

10 minute break

Commitments (up to 60 minutes)

Third, participants will be asked to vocalise their next steps, the commitments they make to their future DH work, so as to create both an individual and collective impetus to act. Participants who would like to continue to collaborate on the Toolkit after the workshop will be invited to join the DHCC Toolkit Action Group.

  • How can we translate what we discussed into concrete next steps?
  • Possible next steps inspired by an earlier DHCC workshop and maybe H4F workshops [10 min]
  • Ask participants what commitments they can make for the next week, month, year, collect those commitments on Jamboard and discuss [20-25 min]
  • Pick a commitment and ecard and schedule the card to be sent in a week/month/year as a reminder

Applying minimal computing principles #

Sayers (2016) notes how a minimal approach can create complex questions and trade-offs. To work in minimal ways means “to define, often implicitly, what and for whom ‘excess’ and ‘essential’ mean in the first place.” For example, it may be important “to share the mess of development with others, and minimalist aesthetics may all too easily afford an impression that everything has been polished or refined from the start.”

Here are some ways you might apply minimal computing principles in service of environmental sustainability:

Minimal languages.

  • Using an efficient programming language can improve environmental impacts. If you have the liberty to make the language decision for yourself, there is some literature about the ecological impacts of these choices. How much energy, time and memory these languages require play an important role here. Humanities researchers often default to high level scripting languages, such as Python (perhaps they are easier for our humanist brains to understand). However, there are consequences for not thinking critically about our choice of programming languages.

  • Python, the go-to language of choice for many Digital Humanities researchers, can be observed in the following table (Pereira et al. 2017) comparing the energy and time factors of Python. Note that ‘time’ in this context means compute time, which is the time the computer takes to run the scripts, and not the time it takes to learn to write the language (although learning time is an important cost of labour factor, it is not a direct environmental factor of computational research activity):

Energy Efficiency across Programming Languages (Pereira et. al. 2017).

Energy Efficiency across Programming Languages (Pereira et. al. 2017).

Minimal consumption.

  • Serverless instances which only consume compute time on demand. However, these require an understanding of the research and technical side to coordinate and operate.
  • Shared libraries at the operating system levels, between the disk sharing and network sharing all add costs. The big providers use lots of memory, which is cheaper than hitting disk, but the consequence is you need big hardware and large scale data centres.

Minimal maintenance.

  • Why are you still running it?
  • On demand infrastructure.
  • Creating cost models
  • Infrastructure is declared - a knowledge system to load the YAML file into to get your emissions costs back would be great - instead of the calculators.
  • Get the ICT service catalogue to update with emissions/costs.

Other principles. Here are some of the other principles to use to plan specific aspects of minimisation.

  • Minimal design
  • Minimal barriers
  • Minimal internet
  • Minimal externals
  • Minimal automation
  • Minimal space
  • Minimal ephemerality
  • Minimal visibility
  • Maximum access
  • Maximum accessibility
  • Maximum impact
  • Maximum mobility
  • Maximising resources.

Static versus dynamic websites -#

As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving the same results for less energy.

Wim Vanderbauwhede

A static website has fixed content which appears the same to every user (until it is manually updated). A dynamic website is generated “on the fly” and is more associated with interactivity. Social media sites are dynamic websites, since they are woven together from a variety of user generated content.

static-v-dynamic-2

Figure: a dizzying diagram of dynamic websites (Image: Partricia Searl, University of Virginia Press.)

  • A dynamic site uses server-side programming languages and technologies to pull information from a database and show it on your browser. All project data and content is stored in a content management system (CMS), which allows for bespoke, personalised, and automated changes to websites. Dynamic sites tend to be content-heavy and user-driven (that is to say the users are interacting with the content in specific ways).
  • A static site consists of a directory of files that lives on the server. This means that when you are accessing web content, you are directly accessing a file on the server rather than making a request to a database or CMS for the content. Pages are therefore accessed as-is and changes need to be made file-by-file.
  • A hybrid web site uses both elements of dynamic and static content.

Why might you choose one or the other (or both)?

There are good reasons to create dynamic websites, but a lot of scholarly projects will do just fine with static sites. Most of us are simply trying to communicate information on our websites: blogs, portfolios, project websites, magazines, documentation sites all can be made cheaply and hassle-free with static site generators. For example, if you are putting your CV online, you do not need a WordPress site to do that well. Static site generators, such as Hugo, even have excellent themes (e.g. Academic) for creating content such as CVs. If you have a collection of transcribed manuscripts, you can also publish that as a static site. Dynamic sites work better and are more appropriate for more complex projects that have interactive features like APIs, search engines, data visualisations, and other structured information stored in databases. That said, even a hybrid site that mixes some dynamic and static content will reduce its carbon impact. Wholegrain Digital offer a tool for estimating the carbon footprint of a website.

Although, it’s a little more complicated.

The benefit from a static site is a little more blurred nowadays, because of the way data gets cached on the web. Browsers store certain data to speed up repeat visits and may send the website an ETag to quickly check if a piece of content has changed. If not, it uses its cached copy. Service providers have similar caching techniques. This means it is not always clear which parts of your backend infrastructure are being hit directly when you use a dynamic site. A good proportion of the content might actually already be stored on your device.

Static Site Generators #

Use a static site where possible. You can do so using a static site generator such as:

Content Management Systems #

However, static sites will never be suitable for everything. A content management system (CMS) is a tool that helps you create a dynamic website without coding. WordPress and Drupal are well-known examples, but there are lightweight alternatives you can use instead:

  • Strapi: An open-source modern headless CMS alternative to WordPress.
  • Ghost: A lightweight headless CMS designed for content creators.
  • Mukurtu: A grassroots CMS project aiming to empower communities to manage, share, narrate, and exchange their digital heritage in culturally relevant and ethically-minded ways.

If you are accustomed to building websites with online CMS platforms like SquareSpace, Wix, or Wordpress, there may be a bit of a learning curve. But it is probably not as steep as it looks, and well worth investing the time. Wagtail is also worth investigating.

Tips for sustainable websites #

Minimal web design for absolute beginners

  • Use fewer videos and images. Make the ones you do use really count! Turn off autoplay for videos, and use lazy loading so that images are only loaded if needed.
  • Shrink your images using a tool like Squoosh.
  • Use the newer WebP image format (but keep your eye on browser compatibility).
  • Create an attractive, accessible design that favours dark colours. On some screen types they use less energy.
  • Do some research and try to pick a green hosting provider. The Green Web Foundation’s directory is one useful resource.
  • Use a tools such as Ecograder and Webvert (in French), to see the carbon impact of your site, and learn more about unnecessary elements (e.g. unused Javascript).
  • Avoid use of large third-party scripts, such as social media plug-ins or “all-in-one” solutions.

It is worth exploring the work of the Green Software Foundation, including the Software Carbon Intensity Specification, which includes a methodology for calculating a SCI score for “any software application, from a large, distributed cloud system to a small monolithic open source library, any on-premise application, or even a serverless function” (Green Software Foundation 2021).

You may also want to investigate the efficiencies of different coding languages. Could this be something you develop in a relatively energy-efficient language like C, C++, or Rust? Mojo is a newer programming language that may be worth investigating too; it promises, “Write Python or scale all the way down to the metal.”

Critical design and system change #

‘Digital technology has ushered in an age of inconspicuous consumption. It is easy to understand the environmental impact of buying ‘stuff’ or flying across the Atlantic. It is harder to wrap your head around how much energy it takes to fly data across the web.’

Arwa Mahdawi, The Guardian

Minimal computing can sometimes feel like fighting a losing battle. Joana Moll’s project The Hidden Life of an Amazon User seeks to make visible the huge amount of code involved in making one simple purchase from Amazon:

In order to purchase the book, the Amazon website forces the customer to go through twelve different interfaces composed of large amounts of code, which is normally invisible to the average user. This code carries out all sorts of operations, such as organizing and styling the site’s content, allowing interactivity, and recording the user’s activity. Overall, I was able to track 1,307 different requests to all sort of scripts and documents, totaling 8,724 A4 pages worth of printed code, adding up to 87.33MB of information. The amount of energy needed to load each of the twelve web interfaces, along with each one’s endless fragments of code, was approximately 30 wh. (Moll 2019)

Do we really have to burn coal so that every user can get personalised recommendations whether they want them or not? Yet these maximalist approaches are everywhere. So how do we also work toward larger structural change? We need to do two things:

  • Adopt and promote behaviour change (such as minimal computing), and
  • advocate for deeper structural changes to support those changes in the longer term.

Although the first point is vital, on its own it is not enough. E.g. a review of interventions at the household level concludes that: “taken in isolation, behavioural interventions have a very small positive effect on climate change mitigation behaviours while the intervention is in place. Once the intervention stops, there is no evidence that such interventions produce lasting positive changes” (Nisa et al., 2019). Rather, lasting positive changes come when there are structures that support and encourage them.

The design of technological interfaces and systems, where the human meets the machine, are among the structures that must change. So are cultural norms, the rules and norms of communities and organisations, and legal and economic structures. So we might think of the link between Minimal computing and system change as a series of opportunities:

  • When a user behaviour is wasteful, there is an opportunity to transform that behaviour.
  • When a user behaviour resists transformation, there is an opportunity to redesign the technical environment.
  • When a technical environment resists transformation, it is an opportunity to redesign the institutional environment.
  • Whenever the institutional environment resists transformation, it is an opportunity to push for deeper legal and economic changes.

In this way, the everyday use of digital systems (for research and other purposes) reveals an abundance of research questions, data gaps, design challenges, exercises you might set your students, opportunities for technological innovation or entrepreneurship, as well as ways to focus and refine advocacy and activism for deeper system change. See “Advocating Within Your Institution” for further ideas.
