Tracking 20 leading cities’ Sustainable Development Goals research

Local challenges help to explain why some goals are prioritized over others.

Leading science cities’ output related to the United Nations’ 17 Sustainable Development Goals (SDGs) speak to research strengths and priorities. This analysis features articles in the 82 selected natural-sciences journals tracked by the Nature Index that were filtered using SDG-related classifiers in Digital Science’s Dimensions database.

Nature Index’s signature metric, Share, is used to measure cities’ SDG-related article output for the period 2015–20. Share is a fractional count for an article allocation to an institution, city or country/region, that accounts for the proportion of authors on the article whose institutional affiliation is with that institution or location. (For more information on the analyses used in this article, see ‘A guide to Nature Index’.)

Top targets

SDG-related output for 20 leading science cities in the Nature Index is mapped against the three leading SDGs in the index. Performance over time is indicated by coloured arrows, which track whether cities’ output related to the three SDGs has increased, decreased or remained the same over the period 2015–20.

A tale of three cities

Baltimore–Washington is the most prolific area for SDG3-related research, with a Share of 264.45. Baltimore is home to Johns Hopkins University, which in 2019 spent a record US$2.9 billion on research and development, higher than any other university in the United States for the 41st consecutive year, according to the US National Science Foundation.

Despite such strong commitment to research, the city has significant health inequalities. The 2018 State of Health in Baltimore white paper reports that life expectancy varies by up to 19 years between neighbourhoods.

Many major science cities are highly active in clean-energy research, often in response to local challenges. Beijing leads, with a Share of 1,241.53 for SDG7. The city hosts the Bluetech Clean Air Alliance, a non-profit organization launched in 2012 to improve China’s air quality. Of its 31 institutional members, 21 are drawn from the Chinese cities highlighted here, including 12 in Beijing.

Institutions in Boulder, Colorado, have the highest proportion of total research output related to all 17 SDGs (16.3%) among the leading 20 cities. The city’s strongest performance is for SDG13 (ranked fifth), with a Share of 197.79. In 2018, Boulder and San Miguel counties partnered with the city of Boulder to file a lawsuit against Suncor and ExxonMobil for contributions to climate change, they claim the oil companies have made — the impacts of which include wildfires and drought.
