The latest   post by  BBC News states,

• It aims to reduce the worst impacts of climate change — but some leaders and campaigners say it does not go far enough.

• The  COP26 agreement — although not legally binding — will set the global agenda on climate change for the next decade:

Emissions

• It was agreed countries will meet next year to pledge further cuts to emissions of carbon dioxide (CO2) — a greenhouse gas which causes climate change.
• This is to try to keep temperature rises within 1.5C — which scientists say is required to prevent a «climate catastrophe»  and limit global warming to about 2.4C.

Coal

• For the first time at a COP conference, there was an explicit plan to reduce use of coal — which is responsible for 40% of annual CO2 emissions.

• However, countries only agreed a weaker commitment to «phase down» rather than «phase out» coal after a late intervention by China and India.

Developing countries

• The agreement pledged to significantly increase money to help poor countries cope with the effects of climate change and make the switch to clean energy.

• There’s also the prospect of a trillion dollar a year fund from 2025 — after a previous pledge for richer countries to provide $100bn (£72bn) a year by 2020 was missed.

Fossil fuel subsidies

• World leaders agreed to phase-out subsidies that artificially lower the price of coal, oil, or natural gas.

• However, no firm dates have been set.

Other  COP26 announcements :

• The world’s biggest CO2 emitters, the US and China, pledged to cooperate more over the next decade in areas including methane emissions and the switch to clean energy.

• Leaders from more than 100 countries — with about 85% of the world’s forests — promised to stop deforestation by 2030.

• A scheme to cut 30% of methane emissions by 2030 was agreed by more than 100 countries.

• The big emitters China, Russia and India haven’t joined — but it’s hoped they will later.

• Financial organisations controlling $130tn agreed to back «clean» technology, such as renewable energy, and direct finance away from fossil fuel-burning industries.

• Most commitments made at COP will have to be self-policed.

• Only a few countries are making their pledges legally binding.

Next year’s COP27 summit is in Egypt.
