Transition into environmental field

Hi everyone! I'm graduating with a degree in business management, but I have a strong passion for the environmental and sustainability field. While I’m considering pursuing a master’s degree to transition into the industry, it’s currently out of my budget. I’ve been exploring alternative options like certifications and came across the Sustainability Excellence Associate (SEA) and Certified Environmental Professional (CEP). However, the CEP requires a bachelor's degree in an environmental-related field and relevant work experience, which I don’t have. I’m thinking of pursuing the SEA certification instead, but I’m unsure if it’s enough to help me break into the field. I feel a bit lost and would really appreciate any advice or professional opinions on how to move forward. Thank you so much!
