2015 marked the target date for the achievement of the Millennium Development Goals and the start of the post-2015 development and climate processes, which ultimately aim to eradicate poverty, improve people’s lives, and rapidly transition to a low-carbon, climate-resilient economy, are mutually reinforcing: when acted on together, they can provide prosperity and security for present and future generations.
Sustainable development, which balances current needs with the needs of future generations, is at the core of the UN’s development agenda.
The UN has shifted to the idea of sustainable development in part because of climate change. According to the Intergovernmental Panel on Climate Change, if climate change is left unchecked, it will increase the likelihood of severe, irreversible changes to our ecosystems. Sustainable development, because it is less harmful to our ecosystems, can help in the fight against climate change. Sustainable development will also help the development needs of the poor and most vulnerable, who have contributed the least to the climate change problem.UN
