The Times Higher Education Impact Rankings are the only global performance tables that assess universities against the United Nations¡¯ Sustainable Development Goals (SDGs). We use carefully calibrated indicators to provide comprehensive and balanced comparisons across four broad areas: research, stewardship, outreach?and?teaching.

Definitions of areas?

Research: the most obvious, and traditional way that a university might help to deliver the SDGs is by creating research in relevant topics.

Stewardship: universities are custodians of significant resources; not just physical resources, but also their employees, faculty, and students. How they act as stewards is one of the key factors in delivering the SDGs.

Outreach: place is critical in higher education, and the work that universities do with their local, regional, national and international communities is another key way that they can have an impact on sustainability.

Teaching:?teaching plays a critical role, both in ensuring that there are enough skilled practitioners to deliver on the SDGs, and in making sure that all alumni take forward the key lessons of sustainability into their future careers.

Which SDGs are included?

There are 17 UN SDGs and we are evaluating university performance on all of them in our second edition of the ranking (click on a category below to view its specific methodology):

ÁñÁ«ÊÓƵ

• SDG 1 ¨C no poverty
• SDG 2 ¨C zero hunger
• SDG 3 ¨C good health and well-being
• SDG 4 ¨C quality education
• SDG 5 ¨C gender equality
• SDG 6 ¨C clean water and sanitation
• SDG 7 ¨C affordable and clean energy
• SDG 8 ¨C decent work and economic growth
• SDG 9 ¨C industry, innovation and infrastructure
• SDG 10 ¨C reduced inequalities
• SDG 11 ¨C sustainable cities and communities
• SDG 12 ¨C responsible consumption and production
• SDG 13 ¨C climate action
• SDG 14 ¨C life below water
• SDG 15 ¨C life on land
• SDG 16 ¨C peace, justice and strong institutions
• SDG 17 ¨C partnerships for the goals

Universities can submit data on as many of these SDGs as they are able. Each SDG has a series of metrics that are used to evaluate the performance of the university on that SDG.?

Any university that provides data on SDG 17 and at least three other SDGs is included in the overall ranking.

As well as the overall ranking, we also publish the results of each individual SDG in 17 separate tables.

How is the ranking created?

A university¡¯s final score in the overall table is calculated by combining its score in SDG 17 with its top three scores out of the remaining 16 SDGs. SDG 17 accounts for 22 per cent of the overall score, while the other SDGs each carry a weight of 26 per cent. This means that different universities are scored based on a different set of SDGs, depending on their focus.

The score from each SDG is scaled so that the highest score in each SDG in the overall calculation is 100. This is to adjust for minor differences in the scoring range in each SDG and to ensure that universities are treated equitably, whichever SDGs they have provided data for. It is these scaled scores that we use to determine which SDGs a university has performed most strongly in; they may not be the SDGs in which the university is ranked highest or has scored highest based on unscaled scores.

The metrics for the 17 SDGs are included on their individual methodology pages.

Scoring within an SDG

There are three categories of metrics within each SDG:

Research metrics are derived from data supplied by Elsevier. For each SDG, a specific query has been created that narrows the scope of the metric to papers relevant to that SDG. As with the World University Rankings, we are using a five-year window between 2014 and 2018. The only exception is the metric on patents that cite research under SDG 9, which relates to the timeframe in which the patents were published rather than the timeframe of the research itself. The metrics chosen for the bibliometrics differ by SDG and there are always at least two bibliometric measures used.

ÁñÁ«ÊÓƵ

Continuous metrics measure contributions to impact that vary continually across a range ¨C for example, the number of graduates with a health-related degree. These are usually normalised to the size of the institution.

When we ask about policies and initiatives ¨C for example, the existence of mentoring programmes ¨C our metrics require universities to provide the evidence to support their claims. In these cases, we give credit for the evidence and for the evidence being public. These metrics are not usually size normalised.

Evidence is evaluated against a set of criteria and decisions are cross validated where there is uncertainty. Evidence is not required to be exhaustive ¨C we are looking for examples that demonstrate best practice at the institutions concerned.

Timeframe

Unless otherwise stated, the data used refer to the closest academic year to January to December 2018.

Exclusions

Universities must teach undergraduates and be validated by a recognised accreditation body to be included in the ranking.

Data collection

Institutions provide and sign off their institutional data for use in the rankings. On the rare occasions when a particular data point is not provided, we enter a value of zero.

The methodology was developed in conjunction with our partners??and Elsevier, and after consultation and input from individual universities, academics, and sector groups.
