A(n) _____ career describes careers in which attention is given to reducing the negative impact industries and society have on the environment.
I suppose this sentence could be completed in with a specific job title or in a more general sense. But since it references "careers," I am thinking that a general adjective might work best, so I would suggest "green." According to the Bureau of Labor Statistics, green jobs are defined as "jobs in which workers' duties involve making their establishment's production processes more environmentally friendly or use fewer natural resources." Green jobs are categorized as those in water conservation, sustainable forestry, biofuels, geothermal energy, environmental remediation, sustainability, energy auditing, recycling, electric vehicles, solar power, and wind energy.
Hope this helps, and feel free to let me know if additional details would be helpful, or if you'd just like to discuss.
