The objective of the research is to design a training program for the professional development of secondary chemistry teachers based on the development of problem solving skills and assimilation of environmental concepts. The researcher designed the program and its tools which were in the list of problem solving skills, the list of environmental concepts that should be absorbed for chemistry teachers, Solving problems, and testing the assimilation of environmental concepts by conducting tribal measurements and then implementing the program and re-measuring again after implementation. The results were to show the effectiveness of the program in developing the skills of solving problem solving skills and developing comprehension of problems The researcher found that there are statistically significant differences between the average scores of the pre-and post-tribal experimental groups in favor of the post-application in the problem-solving skills test, It also found that there are statistically significant differences between the mean scores of the experimental and tribal experimental groups in favor of the post-application in testing the understanding of environmental concepts .Therefore, it recommends reconsidering the professional development programs of chemistry teachers by directing the attention of green chemistry researchers, who seek to provide the teacher with problem solving skills and understanding of environmental concepts
