Study finds 'climate progressive' nations' mitigation plans fall short of Paris Agreement targets by factor of two

The Paris Agreement establishes an international covenant to reduce emissions in line with holding the increase in temperature to 'well below 2°C … and to pursue … 1.5°C.'

Global modelling studies have repeatedly concluded that such commitments can be delivered through technocratic adjustments to contemporary society, principally price mechanisms driving technical change.

However, as emissions have continued to rise, so these models have come to increasingly rely on the extensive deployment of highly speculative negative emissions technologies (NETs).
