Analysis in new report from the Australian National University’s Centre for Climate & Energy Policy shows that producing hydrogen from fossil fuels carries significant risks, and is likely to be incompatible with decarbonisation objectives. These findings have big implications as Australia looks to become a ‘hydrogen superpower’.

On 1 April 2021, Australia’s Emissions Reduction Minister said at the International Energy Agency’s ‘COP26 Net-Zero Summit’ that “removing the price difference between current technologies and low or zero carbon solutions is the key to widespread global adoption” of low emissions technology – and that Australia was focusing on reducing the cost of ‘clean’ hydrogen.

US President Biden has today [26 March 2021] invited 40 world leaders to the ‘Leaders Summit on Climate’ he intends to host on 22 and 23 April 2021.

A new peer-reviewed study has found that the vast majority of Australian voters support climate action, but also highlights that more will need to be done to counter the fact that support for strong climate policy action may be limited by voters’ preparedness to incur personal costs, especially among older and conservative voters.

On top of a post-pandemic economic revival, global warming, biodiversity loss and environmental degradation inevitably will require disruptive economic and social transformations. Without a citizenry that has a stake in making the sacrifices involved, the changes won’t happen.

Professor Simon Lewis draws attention to the need to make carbon accounting trustworthy, and eliminate ‘carbon deceptions’ from approaches to emissions reductions.

The United States officially rejoined the Paris Climate Agreement on 19 February 2021. The US Secretary of State, Antony Blinken, issued a Statement in which he called the rejoining “momentous”, but noted that “what we do in the coming weeks, months, and years is even more important”. You have seen and will continue to see us weaving climate change into our most important bilateral and multilateral conversations at all levels. In these conversations, we’re asking

President Biden’s recognition of climate change, and determination to shift science to the centre of climate policy is important, and welcome. But a program that “achieves a carbon pollution-free power sector by 2035 and puts the US on an irreversible path to a net-zero economy by 2050” will not be enough. Adaptation to a 3.0°C temperature rise this century must now be a focus for governments.

Following US President Biden’s new orders that establish “climate considerations as an essential element of U.S. foreign policy and national security,” the Secretary of Defense released a Statement confirming that “[Climate change] is a national security issue, and we must treat it as such”.

Collective emission reduction efforts of nations will not avoid 3 degrees centigrade global warming by the end of the century. Therefore, national adaptation actions will need to prepare for the worse than expected scale and impact of climate change. Earlier ideological assumptions about governments will have to give way to policies that are interventionist and systemic.

In energy transition conversations, hydrogen is having a bit of a moment. But, as ever, there’s a catch. So here, from the Union of Concerned Scientists’ Julie McNamara, an introduction to hydrogen as a decarbonisation pathway, to help differentiate between the promise and potential and the distractions and misdirections.

Contemplating a world after COVID, some are calling for a reset of existing models of policymaking. In this essay the authors outline shortcomings in existing neoliberal economic models, and argue that the radical pragmatism of effective crisis response—a willingness to try whatever works, guided by an experimental mindset and commitment to empiricism and measuring results —represents a policymaking model that can and should be applied more widely, not only in times of crisis.

Future pandemics will emerge more often, spread more rapidly, do more damage to the world economy and kill more people than COVID-19 unless there is a transformative change in the global approach to dealing with infectious diseases, warns a major new report on biodiversity and pandemics by 22 leading experts from around the world.

The fact that the International Monetary Fund recognises the urgency of addressing anthropogenic induced climate change and the importance of reducing carbon emissions from human activity by 2050 must be seen as a welcome step. But the report is impractical and naïve in some respects. The next step needs to go beyond the high level of abstraction that smooths over the diversity of economic, political and climate impacts in local situations.

Without assistance, emerging economies and developing countries (EEDCs) will continue to add increasing amounts of greenhouses gases to the atmosphere for decades, preventing the curbing of global warming and adversely impacting all countries. While EEDCs were always going to require substantial assistance from the advanced economies, the need for strong multilateral action has become more urgent.

The International Monetary Fund has released its World Economic Outlook October 2020: A Long and Difficult Ascent, calling for global carbon emissions to decline to zero by mid-century, and setting out a model of what might be achieved.

The first multilateral attempt to legally bind countries to emissions cuts will enter into legal force on 31 December 2020, one day before the treaty expires. Does it matter, or is the outcome largely symbolic?

The urgent need to reduce carbon emissions can be usefully compared to filling a bathtub without a drain. Until the emissions tap is turned off completely, the bath keeps filling. And even when the tap is turned off, the bath is still filled to an undesirably high level. If the tap is never turned off, or turned off too late, in time the bath overflows disastrously. The Australian government’s extraordinary new fossil-fuel centred energy plan ensures the emissions tap will continue to flow.

Governments around the world are planning to produce about 50% more fossil fuels by 2030 than would be consistent with the 2015 Paris Climate Agreement pathways. What can be done?

The Paris climate agreement seeks to limit global warming to 1.5℃ this century, a target likely to be exceeded by 2024. This first overshoot would be temporary – but it casts new doubt on whether Earth’s climate can be permanently stabilised at 1.5℃ warming. Modelling shows that if emission reductions are large and sustained, the Paris goals can still be met, and the most severe damage to the natural world, economy and people may be avoided. But worryingly, we also have time to make it far worse.
