“We can provide universal access to energy in Africa primarily through renewable energy. I call for a comprehensive package of support to meet this objective ahead of COP26,” Mr. Guterres said, referring to the UN climate change conference in November.

The United Arab Emirates and the US announced their joint commitment to tackle the climate challenge in a joint statement that stresses the importance and urgency of raising global climate ambition.

Meeting our shared goals for avoiding dangerous climate change requires a dramatic acceleration of progress towards clean growth and resilience.

Bruce Power has committed to achieving net-zero greenhouse gas emissions from its site operations by 2027, building on its previously announced NZ-2050 plan. The company says it is the first nuclear operator in North America to announce such an ambitious commitment.

Grossi said nuclear energy is a longstanding source of low-carbon electricity, has innovative solutions for further decarbonisation, and it enables renewable energy to be more effective.

Nuclear power is relatively expensive and some environmental groups worry about accidents and the storing of spent fuel, which is dangerous. Still, it’s the only source of carbon-free power that can run around the clock.

“Public engagement and acceptance are crucial for the future of nuclear power, and, as reactor designs continue to improve from both a safety and economic perspective, so too will the global community’s perception of this vital source of low carbon electricity.”

"The analyses did not reveal any science-based evidence that nuclear energy does more harm to human health or to the environment than other electricity production technologies already included in the Taxonomy as activities supporting climate change mitigation,"

Over the past few years, Russia has introduced several state incentives aimed at keeping up with the rising role of renewables in the energy mix.

The ecological transition for Europe can only be fully effective, the Commission said, if the EU’s immediate neighbourhood also takes effective action.
