US climate envoy John Kerry on Monday said that cooperation with China on reducing emissions was "the only way to break free from the world's current mutual suicide pact."

"As a large country and economic leader and now the largest driver of climate change, China absolutely can help lead the world to success by peaking and starting to reduce emissions early during this critical decade of 2020 to 2030," Kerry said in a speech in London.

The former US secretary of state and senator compared the global fight against climate change to World War II, saying: "This test is now as acute and existential as any previous one."

"The world order that exists today didn't just emerge on a whim," he said.

"It was built by leaders and nations determined to makes sure that never – never – again would we come so close to the edge of the abyss."

But without "sufficient reduction by China", the current goal of limiting warming to 1.5 degrees was "essentially impossible," Kerry added.

Britain is due to host the COP26 climate summit in Glasgow in November, which will gather negotiators from 196 countries and the European Union, along with businesses, experts and world leaders.

The summit marks a "pivotal moment for the world to come together to meet and master the climate challenge," the US envoy said.

"Glasgow is the place, 2021 is the time and we can, in a little more than 100 days, save the next 100 years.

"Above all we need to provide action, and we need to do it now, because time is running out," he added.

The world must build on the Paris agreement reached in 2016, because "even if every country, fulfilled its initial promises… the temperature of this planet will still rise by upwards of 2.5 or three degrees centigrade", warned the US politician.

He called for a global effort to cut emissions of greenhouse gasses by at least 45 percent by 2030, as the first step to net zero emissions by the middle of the century.

"Let me be clear, we are not saying that every country must, will or can do the same thing, we are saying every country can do enough," he said.

Kerry, who was speaking at the famed Royal Botanic Gardens in Kew, was appointed by Joe Biden to lead US international efforts to tackle the climate crisis.

EU ministers fear populist pushback to bloc's mammoth climate plan
Brdo Castle (Kranj), Slovenia (AFP) July 20, 2021 –

European environment ministers expressed strong reservations on Tuesday against certain aspects of the EU executive's climate plan that they said could trigger populist pushback.

Meeting in Slovenia, bloc ministers gave their first analysis of the dozen proposals that will require approval by the EU's 27 member states as well as the European Parliament.

The mammoth plan was unveiled on July 14 and is intended to transform the bloc's economy from fossil fuel dependency to net-zero emissions.

"Many reservations have been expressed," warned Andrej Vizjak from Slovenia, which holds the EU's rotating presidency, after a meeting with his EU counterparts.

"It will be a difficult puzzle to solve, the Commission will have a lot of explaining to do."

At issue is a proposal that could see fuel and heating costs rise for consumers, which ministers say could trigger a replay of the French "yellow vests" protests.

These erupted when the French government tried to impose a new fuel tax in the name of defending the environment.

"We must not introduce new divisions and inequalities and avoid a poverty trap. This argument resonated (among the ministers)", said Michal Kurtyka of Poland.

To answer the opposition, the commission proposes to set up a 70 billion euro solidarity fund to help citizens make the transition to cleaner lifestyles, but the solution had yet to convince many of the countries most concerned.

The EU's environment supremo Frans Timmermans defended his proposals and asked member states to remain open-minded.

"There is always a risk that people will reject proposals, but sometimes the 'yellow vests' argument is used by those who have very specific interests to defend," Timmermans said.
