The latest analysis shows that if we act now, we can reduce carbon emissions within 12 years and hold the increase in the global average temperature to well below 2°C and even, as asked by the latest science, to 1.5°C above pre-industrial levels.
Thankfully, we have the Paris Agreement – a visionary, viable, forward-looking policy framework that sets out exactly what needs to be done to stop climate disruption and reverse its impact. But the agreement itself is meaningless without ambitious action.
UN Secretary-General António Guterres is calling on all leaders to come to New York on 23 September with concrete, realistic plans to enhance their nationally determined contributions by 2020, in line with reducing greenhouse gas emissions by 45 per cent over the next decade, and to net zero emissions by 2050.
To be effective and credible, these plans cannot address mitigation alone: they must show the way toward a full transformation of economies in line with sustainable development goals. They should not create winners and losers or add to economic inequality; they must be fair and create new opportunities and protections for those negatively impacted, in the context of a just transition. And they should also include women as key decision-makers: only gender-diverse decision-making has the capacity to tackle the different needs that will emerge in this coming period of critical transformation.
The Summit will bring together governments, the private sector, civil society, local authorities and other international organizations to develop ambitious solutions in six areas: a global transition to renewable energy; sustainable and resilient infrastructures and cities; sustainable agriculture and management of forests and oceans; resilience and adaptation to climate impacts; and alignment of public and private finance with a net zero economy.
Business is on our side. Accelerated climate solutions can strengthen our economies and create jobs, while bringing cleaner air, preserving natural habitats and biodiversity, and protecting our environment.
New technologies and engineering solutions are already delivering energy at a lower cost than the fossil-fuel driven economy. Solar and onshore wind are now the cheapest sources of new bulk power in virtually all major economies. But we must set radical change in motion.
This means ending subsidies for fossil fuels and high-emitting agriculture and shifting towards renewable energy, electric vehicles and climate-smart practices. It means carbon pricing that reflects the true cost of emissions, from climate risk to the health hazards of air pollution. And it means accelerating the closure of coal plants and halting the construction of new ones and replacing jobs with healthier alternatives so that the transformation is just, inclusive and profitable.
