In a candid discussion, Lord Nicholas Stern, the renowned economist behind the transformative Stern Review on climate change, reflects on the journey of climate action over the past two decades. As he notes, the challenges have intensified, but so too have the opportunities for innovation and green technology. Despite recent setbacks in climate policy and funding, Stern remains optimistic about the UK’s ability to champion the green agenda globally.
The Evolution of Climate Economics
Two decades ago, Sir Nicholas Stern was tasked by then-Chancellor Gordon Brown to analyse the economic implications of climate change. The resulting Stern Review, a rigorous 700-page analysis, fundamentally shifted the conversation surrounding climate action. It established that climate change is not merely an environmental issue but a significant economic concern, emphasising that the costs of inaction far outweigh those of proactive measures. Stern famously dubbed climate change “the greatest market failure the world has seen.”
Since the publication of the review, the landscape has changed dramatically. The cost of green technologies has plummeted, and global agreements like the 2015 Paris Accord have provided a framework for reducing carbon emissions. Yet, the paradox remains: while green advancements have surged, global emissions continue to escalate, and the repercussions of climate change are felt more acutely than ever.
A Reality Check on Climate Predictions
Reflecting on his original predictions, Stern acknowledges that the realities of climate change have proven to be even more alarming than anticipated. “At the time, we were accused of being alarmist, but in fact, we understated the risks,” he remarked during a recent interview. He highlighted that temperature rises in the UK have already exceeded earlier forecasts, reaching levels of 1.4 to 1.5 degrees Celsius above the late 19th-century baseline, rather than the 1.2 degrees projected.
Despite these challenges, Stern underscores the significant progress in renewable technologies. “We did not foresee that round-the-clock renewables would become cheaper than fossil fuels,” he explained. Additionally, the rise of electric vehicles signals a pivotal shift away from traditional combustion engines. However, he warns that sectors such as heavy industry and aviation must also undergo similar transformations, driven by strategic state investments and regulation.
The Pushback Against Progress
Stern identifies a troubling trend: a growing climate-sceptic lobby that seeks to undermine the logic of the green transition. This resistance is paradoxically a sign of progress; as the UK has achieved a 50% reduction in emissions since 1990, the complexities and challenges of advancing towards net zero have become apparent. Stern observes, “Now that we are in the process of actually doing it, we see that it is difficult and messy.”
He advocates for a more inclusive approach to climate action, emphasising the need to demonstrate the benefits of net zero to the populace. “If we need more air-source heat pumps, we must make them accessible,” he insists, calling for innovative financing solutions to distribute costs effectively. Furthermore, he firmly opposes plans to expand fossil fuel extraction in the North Sea, arguing that true energy security lies in rapidly transitioning away from fossil fuels.
Critique of UK Aid Cuts
Stern is equally critical of the UK government’s recent cuts to foreign aid, which he argues undermine the country’s global standing and commitment to climate finance. Reductions from 0.7% to 0.5%, and now to 0.3% of Gross National Income, are not only detrimental in humanitarian terms but also counterproductive in the fight against climate change. “These cuts are major mistakes,” he asserts. He believes that reallocating funds for defence or health should not come at the expense of crucial climate initiatives.
Despite these setbacks, Stern sees potential for positive change under the leadership of Prime Minister Andy Burnham. He advocates for strategies that encourage private investment in renewable energy and climate adaptation projects in developing nations. With the UK taking a prominent role at the World Bank under Foreign Secretary Ed Miliband, Stern hopes that the country will spearhead efforts to lower capital costs for developing countries.
A Vision for the Future
At the age of 80, Stern’s passion for climate advocacy remains undiminished. He recently published a new book that revisits the insights of the Stern Review, reaffirming that pursuing a climate agenda is essential for sustainable and inclusive growth in the 21st century. In anticipation of the upcoming COP32 climate conference in Addis Ababa, he is collaborating with fellow economist Vera Songwe to develop a sustainable growth agenda for Africa.
Stern’s motivation is deeply personal. “Not doing anything is profoundly dangerous,” he warns, highlighting the urgency of climate action for future generations. His grandchildren, aged 11 to 15, will bear the brunt of the consequences if significant changes are not implemented now. “If we do not make a difference now, we are talking about huge disruptions and the destruction of lives and livelihoods in their lifetimes.”
Why it Matters
The insights of Lord Nicholas Stern highlight the critical intersection of climate action, economic policy, and global leadership. As the world grapples with the immediate impacts of climate change, the need for a cohesive and inclusive approach to sustainable development has never been more urgent. By championing green technologies and advocating for equitable climate finance, the UK can not only lead by example but also secure a healthier planet for future generations. The stakes are high, and the time for decisive action is now.
