What sort of precautions should individuals or organizations take to curb global warming in areas that are at a high risk of air pollution?

a mon avis c'est aux pays industrialisés de trouvés des solutions.

Depends on the law of the country in which one works. 

reduce deforestation and encourage tree planting, avoid activities that produce green house effect gas and governments should introduce environment protection courses in education program from nursery school  

Industries should base their technologies where carbon emission is least. 

Insustrial waste management should be assessed

plant trees, build houses or any other buildings in a eco friendly way with gardens

Measuring the radiation doses lead us to get the desicsin.

It might be a key KPIs of Safety and Environmental team in the organization. They should communicate working plans to address it and together with HR and Ops team work towards its achievement in a systematic and time frame

Go back to nature and think you are not alone on this planet and that humans have to live on this earth in future generations and they need clean surroundings as we do so we must act immediately through other energy resourses and ristricted industry and house wastes plus providing green spaces instead of concrete.  

Practise before preaching. Do and be a role model in wasting the stationary, encourage people to use bicycles and make it as an engagement programme.Plant trees as an organsiation.
