Newly released analysis by the Climate Action Tracker organisation, run by a collection of European scientists, has estimated that global carbon-equivalent emissions need to be halved by 2030 to meet the goal of limiting the global average temperature rise to 1.5^oC above the pre-industrial level. Energy-related carbon emissions were at a record high last year, according to Climate Action Tracker, while only two countries – Morocco and The Gambia – have national plans that would be sufficient to meet the 1.5^oC target (provided other nations raised their targets). Currently, if all pledges made under the Paris Agreement were delivered, CAT estimates that global temperatures would rise by 3.0^oC. In more positive news, that estimate is down from the same organisation’s estimate of a 3.3^oC increase made only in December last year, which is a sign that more ambitious targets are rather rapidly being made across the world.
