The less stringent measure of carbon intensity is also used by developing countries to design targets that allow for growth. Baseline years often coincide with historical peaks in national emissions. The choice of different baseline years by country is another of the complexities in setting targets, making direct comparisons difficult. In August, it stated an intention to reduce its emissions intensity by 45 per cent by 2030 compared with 2005 levels.Įmissions intensity is a goal that is criticised by climate experts because it allows for a rise in absolute emissions, as it measures emissions as a proportion of output. The third biggest annual emitter, India, has more recently set a target. However, it has passed flagship $369bn climate and tax legislation under the Biden administration that experts believe will help it get most of the way to its goal by stimulating green energy development. It has set an economy-wide target of cutting net greenhouse gas emissions by 50 to 52 per cent below 2005 levels by 2030. The US, the second-biggest emitter on an annual basis but the biggest historically, also failed to update its target in the past 12 months, submitting its latest commitment in April 2021. The Geneva-based World Meteorological Organisation estimates that the average global temperature in 2022 was about 1.2C above pre-industrial levels.Ĭhina, the world’s biggest annual emitter and heavily reliant on coal for power, last updated its target in October 2021, saying it would reach a “CO₂ emissions peak before 2030 and achieve carbon neutrality before 2060”. The 2022 year was the fifth warmest on record, according to the US National Oceanic and Atmospheric Administration and Nasa, concurring with the EU earth observation programme, Copernicus. Temperatures have already risen by at least 1.1C since the pre-industrial era. Recent analysis by the UN Environment Programme described these targets collectively as being “woefully inadequate” and indicated “no credible pathway to 1.5C in place”, referring to the 2015 Paris Agreement goal to avoid potentially disastrous planetary changes for global warming.
