Some companies offer cleaner solutions through their products and services, either in terms of energy consumption, emissions, water consumption, waste, etc.
In your analysis, you should start by describing the technology. Then, state when it was released, where and what has been its impact on the environment or society. You must be critical of the green solutions’ limitations.

Make sure to also take into account:
1/ The breadth of the impact
Is the impact local, national, or global?
How many people are concerned? Thousands? Millions? Billions?
As a rule of thumb, if it affects at least 1 million people it is considered significant. Although, please bear in mind that this is not always the case, as, at times, it could be considered unfair to expect an impact to touch that many lives. Thus, this is flexible.
2/ The depth of the impact
Is the life of people concerned deeply affected, or does the issue just marginally impact them?
Are the changes brought by the issue profoundly changing society or the planet?
3/ The persistence of the impact
Finally, make sure the solution has a current impact, and not a future one, and on a significant scale.
