This pamphlet is a challenge to all of us who champion the case for a visionary Green New Deal. It insists on a timescale that cuts carbon emissions in half, within the current decade; demands radical shifts into a more ‘circular’ economics, putting back more than we take out; and a vision that runs beyond obsessions with individual technologies. Instead, the pamphlet focusses on the ‘systems’ that tomorrow’s inclusive security must be built around.
