If only China had the balls to call out Biden for the Obama Administration doing nothing for the environment during those years because Obama didn't want the the blame for any international agreement made when it would fall apart because of US domestic politics.

This is what I've been talking about where China would save itself from a lot of headache if they would call out the US on its own hypocrisy but instead doing what typical Chinese do which is nothing when the US and the West spew out lies.

COP26 has become another annual theatrical climate show. Leaders of public, private and civil society are gathered in Glasgow this week and the next to nudge each other and edge forward a multilateral process to fight climate change collectively.

But this round, there shall be differences. Scientists are providing more affirmative evidence of a crumbling planetary climate system that is crucial to support lives on Earth. The hottest decade on record has put humankind through the hell and horror of some of the most devastating disasters. A global clean energy revolution is embraced as the only pathway forward to mitigate climate warming and enhance human capability and capacity in adaptation and resilience.

As the world's largest greenhouse gas (GHG) emitter today, China and Chinese people bear a sense of urgency and aspire to accelerate its clean and climate-resilient transition. The low carbon economic transition in the last decade has brought evidence and co-benefits from aggressive measures of decoupling its continued economic growth from energy and resources consumption, carbon and other pollutants emissions while investing in non-fossil fuel energy sources and infrastructure.

The Chinese people have learned two things. First, transition is always painful, short-term and even longer-term, but no transition is destructive. The premium or cost of transition won't go up forever. Determination, persistence and perseverance will turn a punishing situation into something rewarding. China's success in developing renewable energy, especially solar and wind energy, electric vehicles (Evs), energy storage and smart power grids in the last decade has made the case. Now a leading global player in both manufacturing and supply chain, China can accelerate deployment domestically and support the global market and other developing countries to embark on a clean energy transition.

which is below even some developing countries while maintaining a high GDP per capita. Many central European countries like Netherlands, Germany, etc still has emissions around 10 tons/capita.

If China can lower emissions per capita back down to Sweden or France levels, that would greatly improve China's energy security and reduce climate change (not for others, but for ourselves).

Surprise surprise though, who are the biggest emitters...?

"Green hydrogen" is a crap idea. You waste 50% of the energy if you do electrolysis of water with energy generated from wind or solar. Then you might lose another 20% on transportation and storage. That is before you consider the energy wasted converting the hydrogen back into electricity. Fuel cells are like 60% efficient at best. Fuel cell manufacture cost is horrendous. The whole thing makes corn ethanol look good. Hydrogen is useful in some chemical processes, but you could just as easily use natural gas for it, in most cases, which is much cheaper.

It makes more sense to use pumped storage if you have that available. It is 90% efficient at storing electricity for later use. Batteries are also 80-90% efficient. You can make huge flow batteries for stationary applications and for mobile applications you have lithium batteries.
