During the past decade, numerous schools in Sweden have implemented education for sustainable development (ESD) as an explicit guiding approach in teaching. In this paper, we investigate the effect of this approach in comparison with that of pupils taught in ordinary schools. Accordingly, we introduce the concept of sustainability consciousness to represent the holistic view of sustainability. Within the concept of sustainability consciousness, we combine and investigate the environmental, economic, and social dimensions of sustainable development in terms of sustainability knowingness, attitudes, and behavior. A Likert-scale questionnaire with 50 items was developed to evaluate pupils’ sustainability consciousness through a nationwide study in Sweden. A total of 1773 pupils from the 6th and 9th grades participated. The results indicated that the ESD profile schools had a small positive effect on the pupils’ sustainability consciousness, while in grade 9 the effect was negative. The implications for further ESD implementation are discussed.

Previous research has shown that interest in and concern about environmental issues tends to decrease in adolescence, but less is known about adolescents' broader consciousness of sustainable development, also including economic and social issues. This study investigates students' sustainability consciousness in the transition to adolescence. This was done by surveying 2,413 Swedish students in the sixth, ninth and twelfth grades using an age-adapted questionnaire. The results unambiguously show that Swedish students' sustainability consciousness dips in adolescence, strongly indicating a need to modify the sustainability education for adolescents. Education for sustainable development is recommended as an approach to meet that need.

This study extends previous environmental education research on gender differences by investigating the gender gap between boys’ and girls’ sustainability consciousness. The issue of whether the gender gap in environmental education can be identified also in sustainability education is addressed. It has been suggested that Education for Sustainable Development (ESD) is a teaching approach that could play a key role in diminishing the gender gap. However, the possible gender-specific effect of an ESD-oriented teaching approach is empirically untested. A survey instrument was used to detect the hypothesized gender gap in students’ sustainability consciousness on a sample of 2,413 Swedish students aged 12–19. Findings reveal a gender gap in students’ sustainability consciousness. The gender gap increases throughout the age span and is amplified in ESD oriented schools.

In recent decades, the Taiwanese government has worked actively to implement the concept of a sustainable Taiwan. As an important step in their strategy, the Ministry of Education has decided to promote the Green School Partnership Project in Taiwan (GPPT). However, academic research and critical reflection on the effects of this environmental and sustainability education initiative are lacking. Therefore, this study focuses on filling this gap by means of a nationwide generalizable effect study. The sampling allowed comparisons between the sixth, ninth, and twelfth grades in GPPT and non-GPPT schools and considered the geographic location (north, center, and south of Taiwan) as well as socio-economic area of the schools. A total of 1,741 students participated, answering a questionnaire that focused on student sustainability consciousness (SC) and its components (i.e., knowingness, attitudes, and behaviors in relation to sustainability). Data were analyzed through structural equation modeling. Our findings make an important empirical contribution, indicating that GPPT schools and non-GPPT schools have a similar effect on the SC of students, i.e. schools engaged in the GPPT do not enhance student SC. In addition, the gender gap regarding SC increased consistently with each increasing grade level, yielding higher mean values for the girls than for the boys. Furthermore, an adolescent dip occurred in the student SC, especially with regard to student sustainability behavior. Given these findings, implications for developing GPPT are discussed; this research could provide valuable informationabout the educational transformation process to enhance environmental and sustainability behavior among students in Taiwan.

Perhaps the most important issue in our time is how to sustain our planet's resources, while developing wealth and well-being for a growing population. This monumental task has been defined in the concept of sustainable development (SD). During the last few decades the world communities have agreed upon addressing SD through international treaties. As a response Education for Sustainable Development (ESD) has been launched as an answer to cope with sustainability. However, empirical studies are a missing link in the discourse around ESD, where decisions and implementation strategies are heavily based on policy recommendations and gut feelings by practitioners. We used data from 2413 students in grades 6, 9, and 12 from 51 schools across Sweden to study the effectiveness of ESD. In line with the current debate on the definition of ESD, we quantified the extent to which teaching can be labeled as holistic and/or pluralistic. Through a series of descriptive analyses and the estimation of structural equation models, our results indicate that ESD can indeed impact on student outcomes in terms of their sustainability consciousness. The results of this study reveal the key role ESD plays in addressing SD, paving the way for a more sustainable future.
