Do yo think the objetives of 2030 agenda can be met if countries like China, India and Russia are not truly involved?

No

No

No 

The selected 3 countries contribute most of the world population and are taking active part in different sectors, like scientific development, industry, sports, economy etc. Excluding the three will no doubt reduce the population burden but at the same time we would be deprived of many things required to meet the target. 

Yes, I think so.

Hmmm. Depends what you mean by "not involved".  Perhaps you are not involved and they are involved. I am a scientist in the Global South. The answers to climate change differ from country to country. Its up to EACH country to find out what it can do better to help prevent global warming and not look around and criticize others - rather consult with them nd ask for technical help if you need it. I think scientists are quite good at consulting globally. Its just politicians who are not!!! LOL!

No

No. Even though all the big superpower economy strong nations are working together, the issue of climate change and sustainability will go beyond many factors and at the global scale. It is a matter of all nations working together and it is beyond 2030.
