Alex Salmond spoke with the UN Secretary General, Premier Wen, President of Iceland Olafur Ragnar Grimsson, President of the UN General Assembly HE Nassir Abdulaziz Al Nasser, President of Kosovo Atifete Jahjaga and Prime Minister of South Korea Kim Hwang-sik.
The First Minister said: "Scotland's energy challenges and champions make us a leader in the international sustainability debate. We are also world leaders in the transition to a low carbon economy and in particular the renewables revolution. It is only fitting that we should be part of the foremost annual meeting committed to finding solutions to the energy needs of the future.
"It is vitally important that, as the world moves towards economic recovery in 2012, we place climate justice at the very heart of the decisions we make on energy policy and economic and social development in the coming months.
"I believe we have a once-in-a-generation opportunity to enshrine this important principle - that economic development should be linked to human rights - in global energy policy, ensuring that countries and communities least able to cope with the extreme weather events climate change brings are not further disadvantaged.
"In the run up to the UN Rio+20 conference in Brazil in June and beyond, I am calling for climate justice to be made central to decisions taken by major countries on energy and development.
"Given that one of the themes of this year's conference is linking the green economy to sustainable development, an important part of Scotland's contribution to Rio+20 will be to champion climate justice."
The First Minister also called for binding targets for greenhouse gas reductions to provide long-term certainty for businesses and investors.
He said: "In Scotland, we have a commitment to reduce greenhouse gas emissions by 80 per cent, from 1990 levels, by 2050. And we also have an interim target of reducing emissions by 42 per cent by 2020 - the most ambitious target of its kind in the world.
"However as we move towards an international agreement on greenhouse gas reductions - and I very much hope that such an agreement will be achieved - we need to be able to ensure that politicians and governments are held to account in the short term, as well as in the medium and long term. The developed world, which is chiefly responsible for past greenhouse gas emissions, must surely take the lead in doing this. "
