The bar graph compares the number of publications by year from 2004 to 2025. The x-axis represents the years, and the y-axis represents the number of publications. There are 13 vertical bars, each representing a different year. The bars show an increase in the number of publications over time. The years 2004, 2011, 2012, 2015, 2016, and 2019 each have 1 publication. The years 2020 and 2021 each have 3 publications. The year 2022 has 1 publication. The year 2023 has 4 publications. The year 2024 has 6 publications. The year 2025 has 16 publications. The color scheme is blue. All values are approximated.Distribution of publications by year in the systematic literature review (n = 39). Note(s): The chart shows the temporal evolution of research in sustainable consumption and green product design from 2004 to 2025. The data reveals three distinct periods: an early foundational period (2004–2016) with sporadic publications, a middle expansion period (2019–2022) with moderate growth, and a recent acceleration period (2023–2025) showing exponential increase in research output, with 2025 accounting for 41% of all publications in the review
