In December 2018, Blackpink donated their prize money from the Elle Style Awards 2018, worth ₩20 million (around US$16,630), to low-income and single-parent households in South Korea. In April 2019, Blackpink made a donation of ₩40 million (around US$33,300) to the Hope Bridge Association of the National Disaster Relief for the victims of the Goseong wildfire in South Korea. In April 2020, Blackpink released face masks via UMG-affiliated merchandising company Bravado; all proceeds benefited the Recording Academy’s MusiCares initiative, which launched a relief fund in response to the COVID-19 pandemic and its impact on the music industry. In December 2020, the group called for action on climate change and promoted the 2021 United Nations Climate Change Conference (COP26), hoping their fans will "join us on this journey" to "learn about what's happening, what needs to happen and how we can play our part." On February 25, 2021, Blackpink were formally appointed official advocates for COP26 in Seoul, where they received a personal appreciation letter written by the Prime Minister of the United Kingdom, Boris Johnson, for their work in the spread of climate change awareness.
