Net Zero Carbon Paris Agreement

The resulting report, published in 2018, found that global emissions must indeed be halved by 2030 – 45% below 2010 levels – and by 2050 they must reach net zero. It found that staying inside the 2C heating would require a net zero until 2070, but the impact is expected to be much worse. Australia has chosen to maintain its 2030 target of reducing 26 to 28 per cent below the 2005 level, and has not yet set a date to reach net zero. The latest research is clear: to avoid the worst effects on climate, global greenhouse gas emissions must not only halve by 2030 and then reach net zero by the middle of the century. The Paris agreement stipulates that countries should make rapid reductions that would “achieve a balance between anthropogenic emissions from sources and the reduction of greenhouse gases from wells” – in other words, net zero “in the second half of this century.” Twenty countries and regions have set zero net targets from June 2020: Austria, Bhutan, Costa Rica, Denmark, the European Union, Fiji, Finland, France, Hungary, Iceland, Japan, Marshall Islands, New Zealand, Norway, Portugal, Singapore, Slovenia, Sweden, Switzerland and the United Kingdom. However, the experts said the agreement also stressed that industrialized countries should play a leading role and be guided by the “best science available.” The main objective of the agreement was to keep the average temperature increase of the planet “well below” 2C and to make “efforts” to limit it to 1.5 degrees Celsius. Climate science is aware that the ultimate magnitude of global warming at some convergence is proportional to the total amount of carbon dioxide that adds human activities to the atmosphere. It is important that the time to reach net zero emissions be significant if we refer only to CO2 or if we refer to all major greenhouse gases (including methane, protein and “F gases” such as fluorocarbons, commonly known as CFCs). For non-co2 emissions, the net date is zero later, because some of those emissions — such as methane from agricultural sources — are a little more difficult to release.

However, these powerful but short-lived gases will increase temperatures in the short term and could push temperature change much earlier beyond the 1.5 degree limit. Comments: In December 2020, in its national proposal to the United Nations, Nepal said it wanted to achieve net zero emissions by 2050 by investing more in renewable energy, electric transport and reforestation. Nepal`s per capita CO2 emissions are among the lowest in the world, but the country is highly vulnerable to the effects of climate change. Glaciers in Nepal`s Himalayas have lost nearly half a metre of ice every year since the turn of the century, and floods and landslides are common.
