The Spring Alliance of European trade unions and civil society organisations wants world leaders to commit to “a concrete action plan leading to sustainable development and poverty eradication within the limitations of the planet.”
The 2nd international Trade Union Assembly on Labour and the Environment called on governments to undertake "a process of profound change in all areas of economic life."
And Stop Climate Chaos Scotland urged the Scottish Government to champion climate justice at Rio+20.
The coalition said Scottish Environment Minister Stewart Stevenson should use Scotland’s progressive stance on environmental issues to influence the global talks.
SCCS wants Scotland to help frame the fundamental change needed to guarantee rights-based sustainable development for all.
Scotland has the strongest climate change legislation in the world, although efforts are needed to ensure the targets within that Act are met.
Tom Ballantine, SCCS Chair, said: “The Rio+20 conference is a major opportunity to refocus on sustainable development and the eradication of poverty.
“Governments must steer away from prioritising ‘the economy’ alone – and instead focus equally on the three pillars of sustainability: the social, the environmental and the economic.
“Climate change, environmental damage and unsustainable consumption of resources – combined with the financial meltdown – all point towards an economic system that isn’t working.”
