This event comes at an opportune time.
The Paris Agreement calls for governments to keep global temperature rise to well below 2 degrees and as close as possible to 1.5 degrees.
We are way off target.
Climate change is running faster than we are.
The commitments made so far by Parties to the Paris Agreement represent just one-third of what is needed.
We risk irreversible catastrophe if we don’t act more quickly and with more ambition.
The world has already warmed by 1 degree.
We are already seeing the consequences for people, economies and ecosystems everywhere.
The IPCC’s 1.5-degree report released last week is clear.
Limiting global warming to 1.5 degrees is still possible and will prevent some of the worst-case scenarios.
To limit warming to 1.5 degrees, greenhouse gas emissions must come down by 45 per cent by 2030 and reach net zero by 2050.
To achieve that, we absolutely must bend the emissions curve by 2020.
As the UN Intergovernmental Panel on Climate Change stressed, limiting temperature rise to 1.5 degrees will require rapid, far-reaching and unprecedented changes in all aspects of society – especially how we manage land, energy, industry, buildings, transport and cities.
That means ending deforestation and planting billions more trees.
It means drastically reducing the use of fossil fuels and massively increasing renewable energy.
It means switching to climate-friendly sustainable agriculture.
And it means considering new technologies, such as carbon capture and storage.
I see three areas where you can make a difference.
First, we need a new economic framework that integrates climate and disaster risk in all aspects of finance, planning and budgeting.
Last year, the economic costs of climate-related disasters hit a record 320 billion dollars.
By 2050, climate change could reduce annual GDP in some countries in South and Southeast Asia by up to 4 per cent.
We cannot afford to ignore climate risk.
Second, we need effective economic policy and fiscal instruments.
We need to put a meaningful price on carbon and end fossil fuel subsidies, which today amount to 373 billion dollars a year.
Carbon pricing and ending fossil fuel subsidies can promote the low-carbon and climate-resilient growth we need.
Carbon taxes or emissions trading systems are now in place or planned in 70 jurisdictions worldwide.
But this coverage amounts to only one fifth of total global emissions.
According to the 2018 New Climate Economy report, carbon pricing and ending subsidies could generate nearly 3 trillion dollars in government revenues or savings by 2030.
Third, we need fundamental shifts in climate financing.
We need to turn global investment in climate action from billions to trillions.
The money is there but the policies that will liberate it are weak or non-existent.
Mobilizing private sector financing is essential.
But public financing and policies need to provide the foundation for the private sector to embrace climate action.
Governments need to encourage their banks to support green financing and innovative financial instruments – such as green bonds -- and debt instruments that can strengthen the resilience of vulnerable nations.
We need to see the Green Climate Fund become fully resourced and operational.
It is also essential that governments fulfil their pledge to mobilize 100 billion dollars a year by 2020 for climate action.
In this regard, President Emmanuel Macron of France and Prime Minister Holness of Jamaica have accepted my invitation to co-chair an initiative to support a political process to meet this pledge.
Finally, we need to avert investment decisions in infrastructure and agriculture that would lock in irreversible, high-carbon unsustainable development.
Some 90 trillion dollars of infrastructure investment is expected by 2030.
It needs to be climate friendly.
As I said, the next few years are critical.
So, I think you can see how your leadership is needed.
Next September, I will convene a Climate Summit to mobilize action and enhance ambition.
We have six areas of focus: energy transition; industry transition; resilience; local action and cities; finance and carbon pricing; and nature-based solutions.
We need to show that countries and businesses are putting in place the policies and instruments that we need.
Between now and then, we have the annual UN Climate negotiations in Katowice, in December.
It is important that this COP is a success.
We cannot afford another Copenhagen.
We need to come out of the meeting with a robust framework that allows countries to operationalize and implement the Paris Agreement.
The negotiations in Poland will require strong and visionary leadership from around the globe.
I count on all leaders to call on their negotiators to resolve all sticking points and insist on progress.
I encourage you all to engage in moving these critical issues forward.
