Getting to net zero CO2 emissions globally means we can halt global warming. This requires a rapid phase-out. It’s physics With another set of global climate talks behind us, the Australian government faces some tricky tasks before it takes over negotiations at the next round of talks next year in Turkey. Cop30 in Belém, Brazil, did not deliver the bold fossil fuel phase-out roadmap we needed, but it did nudge the system forward with more scrutiny of fossil fuel producers. And despite the weakness of the outcome, one can gain some important comfort by the fact that Bélem – and the G20 in Johannesburg at the weekend – both solidly endorsed the Paris agreement, its central goal of keeping warming to 1.5C and the importance of net zero emissions. Cop30 agreed that an “ambition accelerator” will be needed to fill the gap between what governments are planning (projected to warm the world by 2.6C) and the agreed guardrails of the Paris agreement: a limit of 1.5C. It also, crucially, began the momentum for developing a roadmap for a just transition away from fossil fuels, with more than 80 countries – including Australia – signing the “Belém declaration” on a transition away from fossil fuels. While this declaration didn’t get support from the whole conference, Brazil’s president, Luiz Inácio Lula da Silva, has promised to move forward on its implementation during the course of this year, until he hands over to Cop31 in Turkey.

As COP30 comes to a close, read the statement from CA CEO @billhare.bsky.social. This COP did not deliver the bold fossil fuel phaseout roadmap needed, but it did nudge other goals forward.

National leaders must now close the gap between promises and reality.

REPORT: If governments were to implement the promises they made in 2023, to triple renewables, double energy efficiency, reduce methane by 2030 & beyond, they could
✅ significantly cut projected warming - by 0.9˚C
✅ cut warming rate by a third by 2035 and halve it by 2040

The next few years are going to be critical in deciding whether the world can avoid the worst global warming damages, or lock in escalating damages. In this context the upcoming UNFCCC COP30 in Brazil is the most important since the Paris Agreement was adopted in 2015.

We can stop global warming by midcentury if we reach global net-zero CO₂ by 2050
Every year above 1.5°C raises the risk of crossing tipping points—irreversible ice loss, shifts in ocean circulation, ecosystem collapse, increasing economic damage due to heat, flooding, more intense storms.

This means immediate, sustained emissions cuts across all sectors, rapid phase-out of fossil fuels. Countries need to stop using forests to “offset” fossil fuel emissions. We have never been in a better position to achieve this due to rapidly reducing costs of renewable power

Bill Hare @billhare.bsky.social · 28d
Getting back well below 1.5°C before 2100 is still possible, but only if we act now to peak global warming as close as possible to 1.5˚C and minimise overshoot to reduce chance of crossing tipping points and to avoid catastrophic damages.

Conclusion The persistent classification of iron and steel and cement as “hard-to-abate” sectors has shaped both policy and industrial responses in ways that risk undermining the urgency and effectiveness of global climate mitigation efforts. While the technical and process-related challenges in these sectors are non-trivial, the evidence presented in this report demonstrates that their decarbonisation is not only possible but highly achievable with existing and emerging technologies—especially when guided by integrated, whole-of-system approaches and supported by robust policy frameworks. A narrow focus on production-side constraints—such as process emissions in clinker production or the fossil fuel dependence of BF-BOF steelmaking—has encouraged decarbonization strategies put forward by the industry to rely heavily on CCUS and offsetting as core mitigation strategies. This framing assumes that a substantial portion of sectoral emissions are unavoidable, which justifies delayed action and continued operation of high-emissions infrastructure. However, our analysis shows that much of what is labelled “residual” or “unavoidable” emissions can, in fact, be abated at source through a combination of clean technology deployment, material efficiency, and demand-side reductions. In the iron and steel sector, commercially available technologies—particularly electric arc furnaces (EAFs) coupled with high scrap availability and direct reduced iron (DRI) using green hydrogen—can replace the BF-BOF pathway. While steel production capacity is long-lived and capital-intensive, studies show that aligning investment timelines with early retrofit and decommissioning schedules could reduce cumulative emissions by up to 66% over 2020–2050, compared to just 47% if low-carbon measures are delayed by five years.
