As the world grapples with the existential threat of climate change, the term “net-zero emissions” has become a rallying cry for environmentalists and policymakers alike. The idea is simple: by reducing emissions to zero, we can prevent catastrophic global warming and ensure a sustainable future for generations to come. But there’s a growing concern that in our zeal to achieve net-zero, we’re ignoring a crucial aspect of the equation: the environmental and social costs of the technological fixes we’re counting on to get us there.
One of the biggest problems with net-zero emissions is that it relies heavily on a suite of technological solutions that we don’t yet have. Carbon capture and storage, hydrogen fuel cells, and advanced nuclear power are just a few of the technologies that are supposed to help us transition to a low-carbon economy. But what happens when these technologies fail to deliver? Or, worse, when they have unintended consequences that exacerbate the very problems we’re trying to solve?
Take, for example, the push for bioenergy with carbon capture and storage (BECCS). This is a technology that involves growing crops specifically for energy production, capturing the carbon dioxide emissions from that process, and storing it underground. Sounds like a no-brainer, right? But the reality is that BECCS requires massive amounts of land, water, and nutrients – resources that are already in short supply in many parts of the world. And when you factor in the energy required to produce and transport bioenergy, the carbon savings are often nowhere near as significant as promised.

Or consider the case of advanced nuclear power. Proponents argue that new reactor designs can provide clean, carbon-free energy at scale. But what about the waste? Nuclear power produces radioactive waste that can remain hazardous for tens of thousands of years – a legacy that we’ll be passing on to future generations. And what about the security risks? As nuclear power becomes more widespread, the threat of nuclear proliferation and accidents increases exponentially.
These are just a few examples of the kinds of risks and uncertainties that come with relying on technological fixes to achieve net-zero emissions. And yet, despite these concerns, the push for net-zero continues to gain momentum. Why?
One reason is that the narrative around net-zero is deeply entrenched in the policy and business communities. The idea of achieving net-zero emissions has become a kind of holy grail, a symbol of our commitment to the environment and our determination to do better. But this narrative ignores the fact that net-zero is a highly complex and contested concept. It’s a goal that’s been set without a clear plan for how to achieve it, and without adequate consideration of the trade-offs and risks involved.
Another reason is that the pursuit of net-zero has become a kind of moral imperative. We’re told that achieving net-zero is not just a matter of environmental sustainability, but a matter of human rights and social justice. The implication is that anyone who opposes net-zero is somehow complicit in the destruction of the planet. But this kind of moralizing ignores the complexities of the issue and the very real trade-offs that are involved.
So what’s the alternative? Rather than pursuing a narrow focus on net-zero emissions, we need to start thinking about the broader context of the transition to a sustainable economy. This means having a more nuanced conversation about the role of technology, the importance of social justice and human rights, and the need for a more decentralized and democratic approach to decision-making.
It’s time to rethink the net-zero narrative and start asking some harder questions about what we’re really trying to achieve. Is it just about reducing emissions, or is it about creating a more just and equitable world? If it’s the latter, then we need to start thinking about the kinds of solutions that will really make a difference – solutions that prioritize human well-being and environmental sustainability, rather than just focusing on the bottom line.
