New Zealand passed legislation in November 2019 that is expected to achieve zero net emissions by 2050. 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. Notes: Previous administrations have said that Costa Rica will be carbon neutral by 2021, which… it did not happen. In February 2019, President Carlos Alvarado Quesada presented a package of climate measures. A long-term strategy presented to the United Nations in December confirmed the target of net zero emissions for 2050. The country is regularly acclaimed for receiving almost all of the electricity generated from renewable energy sources, including hydropower, but citizens still need gasoline and diesel to get around. A decree on e-mobility adopted in 2018 is expected to change that. Hungary has set a binding target of achieving zero net emissions by 2050. In the face of this urgency, an unprecedented number of economic and local government leaders are supporting strong national climate ambitions through the UN Climate Plateau Champions` „Race to Zero” campaign. The global initiative sets minimum criteria for setting zero net targets and calls on regions, cities, businesses, investors and civil society to commit to zero net emissions by 2050 and to present a plan before the next UN climate change summit in 2021.
This is done on the heels of the UN Secretary-General, who is calling on countries to present zero net targets. In addition, more and more countries have joined the Alliance for Climate Ambition in order to achieve net zero emissions. This is why it is important for countries to indicate whether their net zero targets cover only CO2 or all major greenhouse gases. An overall zero net emissions target would cover all major greenhouse gases and ensure a reduction in non-CO2 gases. 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. „Together with the EU and the UK, they have explicit targets to achieve net zero-yield gas emissions by 2050, and they have a political architecture close to it. They also have comprehensive regulations. Australia has absolutely nothing to do with it. But there is a big loophole in the government`s climate proposal, because it does not involve achieving net zero for methane emissions – which probably capture about 30 times more heat in the atmosphere than CO2. He said there could be a lasting legal dispute over whether the Paris agreement would require net zero by 2050, but Australia should not „lock itself into legalism.”
