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

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..their active participation is necessary 

No, they have to involve 

No. They are too big and would need to be on board to meet global targets. 

No. These three countries account for about half of the global population and a good percent of the global economy. They are also among the largest countries in the world. So, to me not only their involvement but sincere participation is critical for realizing 2030 agenda. 

No.  The agenda is an aspiration.  Without it nothing will happen; with it, slow progress will occur consistent with the economic conditions of the various countries that contribute the most to climate change.  The process of moving away from fossil fuels is a transition that will take decades and is driven by more than just climate issues.  Note also that all international agreements are just "good faith".  There is no penalty for violations. And, what is promised today, is by one political administration. There is no deal that all future political administrations will honor it.  When administrations change, the promise can be broken outright.  

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.

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.
