Pledges made under the PPCA to phase out 'unabated' coal-fired power aren't enough to reduce emissions, experts have warned.
The Powering Past Coal Alliance (PPCA) is a coalition of 30 countries and 22 states which aims to phase out coal power for cleaner air.
Database - Coal - Power - Plants - Team
By analysing a worldwide database of coal power plants, the team have shown that only wealthy countries, which don't use much coal, have joined the PPCA.
The research also shows that expansion of the PPCA to major coal consuming countries mean they would face economic and political difficulties.

Global energy experts also found that members of the PPCA mainly promised to close older plants near the end of their lifetimes anyway, resulting in limited emissions reductions.
They found that pledges from PPCA members will result in a reduction of about 1.6 gigatonnes of C02 from now until 2050.
C02 - Emissions - Time - Period - Coal
This represents only around 1/150th of projected C02 emissions over the same time period from all coal power plants which are already operating globally.
'To keep global warming below 1.5°C, as aimed for in the Paris climate agreement, we need to phase-out unabated coal power – that is, when the carbon emissions are not captured – by the middle of this century,' said Jessica Jewell.

Ms Jewell, an assistant professor at the Department of Space, Earth and the Environment at Chalmers University of Technology said: 'The Powering Past Coal Alliance is a good start but so far, only wealthy countries which don't use much coal, and some countries which don't use any coal power, have joined.'
To investigate the likelihood of expanding the PPCA, Professor Jewell, who led the study, compared its current members with countries whic aren't in the Alliance.

They found that PPCA members are wealthy nations with small electricity demand growth, older power plants and low...
