United Nations: on Energy & Oil

Mike Bloomberg: US must set real and binding carbon reduction targets

However, between now and the Copenhagen Conference next year, we must establish, I think, the preconditions for such progress. Both developed and developing nations must recognize the need to alter their policies and make serious commitments to change. And I believe that our experience in New York City, and the experience of many of the world's other great cities, too, can help guide that process.

The first precondition for making the Copenhagen negotiations a success, I believe, is that the US, which leads the world in greenhouse gas production, must finally set real and binding carbon reduction targets. And I believe the American people are prepared to accept our responsibility to lead by example.

Mike Bloomberg: Reducing carbon output increases socio-economic well-being

1. We're converting our city's taxi fleet to hybrid cars, reducing carbon by 1/2%. It will also clean our air of pollutants.
2. We've proposed a program of congestion pricing, designed to discourage driving in our busy business district during the peak weekday hours. It will also make our economy more productive, and finance the new transit lines we desperately need.
3. We're working to green our buildings--again, not just to cut carbon emissions, but also because it will allow us to redirect billions to better purposes.
4. We're planting one million trees throughout our city during the next ten years. They will not only capture carbon dioxide, but also clean the air, cool our streets, reduce street flooding, and raise property values.

Mike Bloomberg: Cities are taking the lead on climate change

It's why, even though our national government has yet to approve the Kyoto Protocol, more than 700 cities in the US, representing more than 80 million Americans, have pledged to meet its goals. And it's why, later this year, NYC will convene a 2-day conference of representatives from more than 20 major world cities. It will feature experts in such fields as transportation, city planning, public health; and it will address the challenges that the world's cities share in reducing urban air pollution and curbing climate change.

Barack Obama: America will join China in Paris Climate Agreement

U.S. President Barack Obama and Chinese President Xi Jinping announced in Hangzhou, China, where the two leaders have met in the context of the G-20, that their countries have officially joined the Agreement.

The Paris Agreement commits parties to take action to keep global temperature rise well below 2-degrees Celsius to stave off the worst impacts of climate change on health, food security, and extreme weather. The agreement will enter into force 30 days after at least 55 countries have formally joined, representing at least 55 percent of the world's global greenhouse gas emissions. China and the United States together make up 38 percent of the world's emissions, and the fact they have officially joined the agreement this early marks significant progress toward ensuring the Paris Agreement takes effect quickly.

Liz Truss: Transition to gas then future of renewable & nuclear energy

We are cutting off the toxic power and pipelines from authoritarian regimes and strengthening our energy resilience. We will ensure we cannot be coerced or harmed by the reckless actions of rogue actors abroad.

We will transition to a future based on renewable and nuclear energy while ensuring that the gas used during that transition is from reliable sources including our own North Sea production. We will be a net energy exporter by 2040.

Pope Francis: Moral imperative to address climate change

Speaking to more than 1 billion Catholics around the world, Pope Francis is a powerful and influential voice. So when the Pope states that humans are causing climate change and argues that we have a "moral imperative" to address it, as he did in today's encyclical, the world takes notice. "The climate is a common good, belonging to all and meant for all."

Rishi Sunak: Can we summon the collective will to tackle global warming?

He is expected to call on governments to deliver on the promises made at COP26 in the Scottish city of Glasgow a year ago, when host nation Britain helped to broker a wide-ranging climate pact - much of which has yet to be implemented.

"The world came together in Glasgow with one last chance to create a plan that would limit global temperature rises to 1.5 degrees. The question today is: can we summon the collective will to deliver on those promises?" he will say, according to extracts released by his office in advance.

The chances look slim. A United Nations report at the end of October said government pledges to cut greenhouse gas emissions put the planet on track for an average 2.8 Celsius temperature rise this century after "woefully inadequate" progress.

Vladimir Putin: Reduce Russia's greenhouse emissions by 70% by 2030

I suggest, however, we should take a wider view on this issue. Yes, we might defuse the problem for a while, by setting quotas on harmful emissions or by taking other measures that are nothing but tactical. But we will not solve it that way. We need a completely different approach.

We have to focus on introducing fundamental and new technologies inspired by nature, which would not damage the environment, but would be in harmony with it. Also, that would allow us to restore the balance upset by biosphere and technosphere upset by human activities.

We propose convening a special forum under the U.N. auspices for a comprehensive consideration of the issues related to the depletion of natural resources, destruction of habitat and climate change.
