An alliance of over 20 organisations, including Oxfam, WWF, Cymdeithas yr Iaith Gymraeg, Friends of the Earth and Christian Aid, is calling for Welsh Ministers to deliver a 'strong and effective' Well-Being and Future Generations Bill, ahead of its launch.
Ministers have pledged 'ground breaking' legislation which will make sustainable development the 'central organising principle' of government and the devolved public sector in Wales.
But following concerns that the Welsh Government's initial proposals were too weak, the Sustainable Development Alliance is calling for the Well-Being and Future Generations Bill to set clear goals to live within the finite resources of the planet, and to ensure that decisions taken by public bodies minimise negative impacts outside Wales.
Chair of the Sustainable Development Alliance, Anne Meikle, said:
"Wales must be truly fit for the future, in the face of massive global challenges. So today it's crucial that Ministers deliver on their promises, with a strong and effective Future Generations Bill that can tackle big issues such as poverty, protecting wildlife and supporting the Welsh language.
"We need to be ready for a future of fierce competition for scarce natural resources, and we need to recognise our global impacts, for example playing our part in addressing climate change.
"We can't afford to saddle future generations with more problems. Instead, we want to see a bill that ensures public bodies make the right decisions, to meet the needs of our children and grandchildren by delivering good jobs, thriving communities and a healthy environment."
The Alliance says that putting sustainable development at the heart of decision-making is vital for meeting the social, environmental, cultural and economic challenges facing Wales and meeting the needs of future generations
The alliance agrees the legislation must include:
A strong definition of sustainable development
A strong duty on the devolved public sector to achieve sustainable development within its functions
A powerful, independent Sustainable Development Commissioner
