- Climate tech has shifted from niche policy discussions to mainstream action, driven by rapid growth in the circular economy and strong public demand for governments to tackle climate change.
- Improved measurement frameworks, international agreements and mechanisms such as the EU ETS and CBAM have made emissions tracking more accurate, enabling organisations to manage and reduce carbon more effectively.
- The sector now emphasises science-based targets, cross-disciplinary collaboration and transparency to ensure genuine decarbonisation, with policymakers playing a crucial role in accelerating large-scale change.
It’s only in the last few years that environmental issues truly moved from specialist conferences and policy papers into supermarkets, boardrooms, and the headlines. The renewed attention makes it a particularly exciting time to enter the climate tech industry.
The circular economy market reached $518 billion in 2025, and is expected to grow to $888 billion by 2030; research suggests 89% of people across the world want their governments to do more to combat climate change; and environmentalism is now a mainstream movement.
You can’t reduce what you don’t measure
Just two decades ago, high-level average emission factors were the norm, and benchmarks were rare and often inconsistent.
Over the last few decades, the landscape has changed in ways that make our work far more impactful: now in its fourth phase the European Union Emissions Trading System (EU ETS) introduced a cap-and-trade system for emissions in 2005; the Paris Agreement unites over 190 countries to commit to limiting temperature increases; and the latest development, EU’s Carbon Border Adjustment Mechanism (CBAM), places costs on carbon emissions, subjecting importers that fail to accurately report embedded carbon emissions of their imports to high default costs.
These developments have resulted in measurement and transparency improving dramatically. We’ve seen the creation of rigorous product and corporate measurement frameworks, wider adoption of life-cycle thinking, and growing demand for primary, company-level data, rather than country or industry averages.
This matters because the better we measure, the better we can manage. As the saying goes, you can’t reduce what you don’t measure.
Systems thinking
That progress is also reshaping the expertise required in the field as well. Greenhouse gas expertise used to be a niche that grouped emissions into a handful of easily defined buckets. Today, it covers multiple disciplines: life-cycle assessment, supply-chain mapping, data engineering, verification protocols, and regulatory interpretation.
Scientists, data specialists, and policy analysts now work alongside product teams and procurement and finance departments. For those entering or advancing in climate tech, this cross-disciplinary environment is an opportunity, as it rewards good communication and collaboration.
The ongoing challenge
At the same time, not everything has changed. One of the biggest ongoing challenges is conveying complex environmental concepts in ways that meaningfully influence everyday decisions, such as when someone is deciding whether to take a short domestic flight or opt for the slower rail. Public education remains essential, and individual choices do add up.
However, the main drivers of significant, rapid change are policymakers. They can accelerate progress through both regulation and incentivisation, the carrot and the stick. The impact of these drivers becomes particularly visible when industries improve performance across global supply chains, where change can be scaled quickly and consistently.
Aligning corporate performance with science
Because of this, climate technology increasingly focuses on aligning corporate performance with robust science. The next technical step is helping organisations meet specific emissions targets, including the Science Based Targets initiative (SBTi), net-zero roadmaps, and sectoral decarbonisation pathways.
These commitments move the needle because they require primary data collection and supplier engagement, as well as concrete reduction plans. The new generation of climate tech tools does not simply estimate emissions; it enables measurement at scale, with increasing accuracy.
That, in turn, allows organisations to manage emissions through operational improvements and capital investment choices.
Working in this space requires a strong commitment to transparency and vigilant resistance to greenwashing. Following carbon accounting standards ensures assessments are credible and capable of driving tangible change.
Such an approach prevents the creation of an illusion of progress, when in reality carbon burdens merely shift from one area of a supply chain to another. It ensures that there is real impact.
Climate expertise at home
The climate-conscious mindset should extend to personal life: how food is prepared to reduce waste; opting for low-carbon meal ingredients; thinking twice about fast fashion and choosing higher-quality clothes less often; and weighing the true cost and emissions of car ownership versus alternatives.
These choices are not always simple and often clash with time constraints, convenience, and household budgets.
There is also a good representation of women in climate-related roles, which is encouraging. Even in more traditionally male-dominated areas, like tech, the numbers seem to be growing. Many companies are starting to recognise that diverse leadership leads to better outcomes.
Why this moment matters
As a field, climate tech has moved beyond awareness and into action, measurement, and accountability. The tools are better, the data is stronger, and despite political headwinds, the demand for science-based action has never been higher.
For those of us working in climate tech today, the challenge is no longer whether change will happen, but how fast and how fairly it will unfold.
