The environmental conditions that induces the oxygen to bind to hemoglobin is oxygen rich environment.
When the concentration of the oxygen in the environment is more as compared to that of carbon dioxide then the by the process of diffusion cell uptake oxygen and form oxy-hemoglobin.
This oxy-hemoglobin is then transported to the various cells of the body which supplies oxygen to the cell for its function.
An environment high in carbon dioxide and high in oxygen induce oxygen to bind to hemoglobin. Another factors are an environment under high pressure and an environment under low pressure.
